amm_iphone6If you own a smartphone, I’m sure you are hooked onto Facebook, Twitter and Instagram. Even if you are not, you would also like to stay connected to your loved ones back at home, by using Whatsapp, LINE or WeChat.

Why pay hefty fees to your telcos when you can get stay connected in Bangkok for a lower price by getting their 4G Prepaid SIM card with Unlimited Data!!!

These are the telco operators in Bangkok offering 3G Prepaid SIM Card. Meanwhile, you can click on their respective pictures to check out the details (link updated with their respective promo page in English).

Getting the data sim cards with unlimited data, it saves all the hassle of topping it up daily as what I want is to use Whatsapp, Facebook, Twitter and Instagram. I also use it to do some local calls especially when I want to call some restaurants to make reservations or even to book a taxi via GrabTaxi.

Suvarnabhumi Airport (BKK)


Upon clearing the immigration at Suvarnabhumi Airport, proceed to your preferred telco counter on the same level (located at Arrival Hall, between gate 6 and 7).

299 baht

  • Unlimited data bundle for 1 week (7 days)
    • If you are staying for more than 7 days, not to worry because they have plans for 15 or 30 days too.
    • The first 1GB is high speed and subsequently will be at a lower speed
  • 100 baht of free talk time

Just tell the counter staff what you require. They are able to understand and converse in simple English. Just pass them your phone and they will help you to activate the service.


Suvarnabhumi (BKK) – AIS, dtac, trueMove : 24 hours

Don Mueang Airport (DMK)

At Don Mueang Airport (DMK), you will be able to find trueMove and dtac. true is open from 10am to 12am while dtac is open 24 hours.


You can find trueMove at Terminal 1 which can be easily seen on your way out after collecting your baggage.


dtac’s new 24 hours shop is located at Level 1, in between Terminal 1 & 2. If your flight arrives late (after midnight), I suggest you get your card here.

Alternatively, you can get the Prepaid SIM cards of the other telcos at the convenience stalls there. There are 2 convenience stalls there but it seems like they are offering different prices.


City (Central World / Siam Paragon)

If you want to have it done in the city, head on down to Central World or Siam Paragon.


Central World: AIS (Level 4), dtac (Level 4)


Siam Paragon: AIS (Level 4), dtac (Level 3)

Singapore Changi Airport

For Singaporeans, if you want to avoid all queues at Suvarnabhumi or Don Mueang, you can purchase the AIS Prepaid SIM from Changi Airport Recommends.

Update: You will need to press *120 to activate without having to head over to AIS counters. This is part of the new regulation change in Thailand which requires this additional step.

24 hour Locations:

Terminal 2 – Arrival & Departure Hall (Public area)
Terminal 3 – Arrival Hall (Public area)

For detailed location, please visit Changi Airport Recommends.

  1. hi, other than the airport, is there any other places in the city that i can pirchase the sim card as well?

      1. Hi Aroi,

        I am travelling to Bangkok this coming 13th to 17th Nov and wanted a pre-paid micro SIM card. Understand that DTAC offer 299Baht for unlimited data usage withotu adfditional charge and local 100min call. Is this still on offer? Also do I need to pay addiotnal for the SIM card? Appreacite your response. I need more data than voice. If I wanted 4G instead what is the best service operator to use? I will mainly focus in Downtown Bangkok area.

  2. Dear Sir
    I will be travelling to bangkok for 7 days. I would like to take a sim which gives me data free around 50mb. I found this sim DTAC HAPPY SMARTPHONE SIM ? But I dont know if it is for thai residents or foriegners too? please help

    1. No worries, it is available for foreigners too. Just head on down to DTAC counters at Airport / Central World / Siam Paragon. They actually sell it as a bundle package for 7 days with unlimited data.

  3. To help those who need this in the future, both the airport and central world locations
    were totally out of these. Make it easier on yourself and stop by any 7-11 and
    they have them. Btw, it’s 299 baht, a bargain.

    1. Hi Happy, 299 baht for DTAC prepaid card with unlimited internet? wow.. good deal. just insert the SIM card to use or require to do configuration? What is the speed they offer? thanks.

      1. Just insert the SIM card and follow the instructions on the package. If you are at DTAC counters, they will help you to activate the service. The speed of dtac 3G is up to a maximum of 384Kbps.

  4. Hi, I will be in Bangkok for 4 days. Is it possible to get Happy Tourist sim 49 and purchase daily 3G internet ? What would you recommend?

  5. Hi Happy, if im staying bangkok for 3 nights. Is there any prepaid sim for internet only ? I remember when I was in koh samui. I bought the happy sim for 5 days internet access only for 250 baht where calls will be charged separately as per use. Thanks

    1. You need to purchase the SIM Card and indicate to them that you want a INTERNET Plan, they will be able to assist you further as they have various plans. There is no dtac counter at Don Muang Airport currently.

  6. Also I wonder if there’s any dtac counter at don muang airport? Can I know their operation hours as I will be arriving about 10-11pm local time. Thanks.

  7. Dear aroimakmak,
    I am a frequent Bangkok travelers, I come Bkk almost every month and I stay for about 4-5 days each time. I already got myself a happy tourist simcard, it is really a worry free SIM card for mobile. My question is,
    Since the package is for 7days, can I use back the same number during my next visit ? Do I get back the same package upon top up? Can you show me how?
    Second question, dtac data and speed isn’t enough for my usage during night time as I usually will surf a lots of nets and watching YouTube, too bad that my hotel do not provide us free wifi. So I got myself a mifi unit to work as wifi router, my question is, is there any Internet package is suitable and affordable to use for 7days or less? I just want to avoid monthly package type. Preferable prepaid with 7 days package

    Wish to get your reply as soon as possible. Thank you

    1. The total accumulated validity is 90 days. To check balance and validity, please press *101*9#. To keep the number active, you just have to topup to the same SIM Card / Number.

      The most suitable plan will be the tourist SIM as it is with 1 week of unlimited Internet usage.

  8. Hi. I’ll be travelling to Bangkok in November while my friend’ll be travelling there by the end of this month. What if I ask her to buy the dtac SIM card for me and I’ll use it when I’m in Bangkok? The Sim card which bought in 7-11 is just the same with the one bought at airport right?

    1. Hi, it is possible for your friend to get for you and you activate only when you reach Bangkok. Do check the validity of the card when purchasing though. Yes, the dtac card at airport and 7-11 is the same. dtac helps you to activate it while 7-11 does not. 🙂

        1. Yes, you will have to activate it yourself if your friend buys for you / you get it from 7 eleven. The instructions in the english manual are straightforward. However, if you want the staffs to activate for you, then you will have to get it from dtac stores.

  9. I bought the card at Suvarnabhumi Airport before and the staff there just gave me the card and asked me insert it into my phone by myself. I didn’t see him did anything on the card though but it could be used right after I inserted it into my phone(they’ve already activated the card??). This time I will be landed at Dong Muang Airport and there is no dtac service counter right? Sorry for asking so many questions and thank you for answering me:)

    1. Actually the card will activate on its on upon inserting into the phone. However, at times, some models require some additional settings and that is when the service staffs come in. Yes, the plan comes in Micro SIM card.

      You are right! There is no dtac counter there. You should have no problem with you card. The worst case scenario is to head on down to Central World or Siam Paragon if you encounter any problem. 🙂

  10. Hi, I bought a dtac sim card at a 7-11 in Bangkok, but realize now I actually needed a micro sim. Can I go to a dtac counter anywhere to have them trim it for me? Or do I have to buy a new one? Thank you!

    1. I’m not sure if dtac is able to trim for you. You can go to mobile phone shops to see if they are willing to trim it for you though. Otherwise, the other way is to purchase a new one.

  11. I had a dtac no. But I have forgotten that as it is the 2 years back my last thai visit was. So. Please tell me the code so that I could retrieve the no.


  12. If i am arriving at Don Muaeng airport and staying at Baiyoke sky hotel, which is the best place to get the happy tourist sim?

  13. Hi all

    Any suggestions for a pre-paid sim card allowing 4G internet access in Bangkok for 3 days?

    I will be using Samsung Note 3 LTE for the trip, just for internet surfing.


  14. Dear Sir/Madam,
    I shall be @ SUVARNABHUMI Airport about Late FEBRUARY 2014.
    Please help me find WHERE I can purchase:
    1) the CHEAPEST Mobile Phone SIM CARD for TEMPORARY USE,
    2) @ What COST ( in Thai Bhat ), &
    3) How to COMMUNICATE THIS to the Counter Staff???
    Thank you.

    1. Hi Pat, how many days will you be in Bangkok? You can either go for AIS or dtac SIM Tourist Package which comes with 7days of unlimited data plus 100mins free outgoing calls. The cost is 299Baht. The counter staffs are able to converse in English. 🙂

  15. Dear Mme, Sir Aroimakmak,
    i will stay nearly 2 months in Bangkok. i will arrive Bangkok next week sat 7th June. Can you recommend me which brand sim card i should buy? it will be especially for using data internet probably . Video streaming most of the time minimum 3 go per month. In the past 4 years ago i used I-Kool Internet data prepaid data. But it is difficult to find.
    What do you recommend me ?
    I heard TOT sells now IPTV box. But i would like to use 3g sim card

    Didier France

    1. Hi, I will recommend you to use AIS. They have monthly unlimited data for 299baht but also plans for 2gb / 3gb. Just proceed to the counter to checkout the prices when you reach Bangkok.

    1. I would recommend you to purchase the 7 days on data for 299 baht. If you want exactly 4 days, you have to top-up daily and it is not worth the effort.

      1. Hello,
        I leave for Bangkok tomorrow morning and was wondering if I can get one of these SIM cards with these amazing plans for my iphon5 IF it is not unlocked?

  16. I have a SIM card from 7/11 but my phone tells me to ask the carrier to allow access.. How do I do this?

  17. Hi, I will be landing in don muang airport, so is the 7-11 there able to purchase the micro SIM card 3G? If not where else can I purchase? Platinum mall or?

  18. Hi, i’m not sure if it’s too late nor you will reply this but i will just try my luck.

    I’m heading to BKK in this coming Sept for around 3 days 2 night, which data plan is suitable for me because i feel that if i were to get the 299BAHT data plan is a waste for me, the remaining 4 days i won’t be in BKK anymore. Please advise me on which data plan i could get, thank you :}

    1. Hi, I would prefer buying the 299 baht plan as it saves me the hassle of trying to top-up everyday. And I tried it before, it’s quite troublesome. So 299 baht is worth it as I can just use it for my days in Bangkok without worrying. 🙂

  19. Hi, I will be in BKK for 3 weeks and would like to get a prepaid SIM card. Which one is the best considering that I will use more data than voice/text. Actually, I will use lots of data. I need to card that gives me the best ratio quantity:price. tx!!

  20. I bought a dtac at the airport. I inserted in my android, however it doesn’t detect the simcard at all. And I’ve left the airport. I’m using a Samsung for duo simcard. Does this mean it can’t be used in my android?

  21. Hi, do you know what time the counter at Suvarnabhumi Airport closes? I will be arriving there past midnight.

    Thanks in advance 🙂

    1. I personally prefer AIS for now as their network is more consistent. Unfortunately, their networks are not LTE at the moment. It will be 3G or 3G+ most of the time.

  22. Hi there,

    I am a frequent traveller to Bangkok and would like to know if there is any prepaid sim card which will enable me to use for long and keep the same number as long as I top up the value before the value expiry date? For example assuming if the value in the card is having 30 days expiry date, and every top up will extend the validity for another 30 days or before finishing up the value. So as long as I keep topping up (might have a minimum top up amount?) before each expiry date, then I can keep using the same sim card for long? Is there such a card?

    1. Hi, in fact every prepaid SIM card can be reused as long as you top up when you return. However, doing this, it will be more expensive than getting a brand new SIM card. So it really depends on whether you want to keep the number of you want to save the money. 🙂

  23. Hi, i would like to ask if the 299baht for 7days unlimited data package able share among 2/3 devices? i mean hotspot. and is the deal still available in nov2014? thanks for responding

  24. Hello I saw from the previous comments that it is possible to get a prepaid card that can last for a month at the cost of 500 to 1000 baht. May I ask if this prepaid card has unlimited data usage and they do not require any further top up right? Is it possible if I activate the card when I want to use it? (as I am thinking of getting a friend to get that prepaid card weeks before my trip).

    1. Yes, it has unlimited data as well. It will be better to purchase the card when you get there so that the staff can do the activation for you. You probably got to get your friend to check with them if activation can be done later and what are the steps.

  25. Hi aroimakmak, i am a frequent bkk traveller for business purpose, so i visit Bkk once or twice a month and each time about 5 to 6 days, and i already hooked up to AIS unlimited social prepaid which is good enough to do those wechat whatsapp line etc, but the speed is quite slow, and the wifi that hotel provided is always slow and sometimes not even working, i have tried few different hotel to be honest and i think that was the problem from service provider.
    So all the while i am looking for a MIFI device that can provide me personal wifi or data and the challenge is I do not know which provider to go for, most of them my capped after about 500mb to 1gb which i think i could finish the quota within a day, and some of them just too expensive to pay just for 5 days use. And what i might need is unlimited usage and not capped for just 5 days. So I can activate the service each time i reach BKK.

    So in here, i would like to get your advice, what type of service i should pay attention to and i wish to know your best suggestion to my needs…. Really wish to get your professional opinion.
    I am willing to change my current AIS number for your info.

    1. Hi Anson. I have tried all 3 telcos (dtac, AIS, true) for their tourist prepaid card and I felt them in terms of network and speed, the most value for money would be AIS. The network for dtac may not be that strong at some places while many said that true is the best in terms of network but their plan is not that value for money if you are looking for unlimited data.

      Did you purchase the traveller’s SIM previously from AIS? They actually have plans for half or one whole month. But just bear in mind that the staffs have told me that it is actually slightly more expensive to top up and retain old number than get a brand new number. But for business it would be better to keep the same number. If no prepaid card is able to suit your usage perhaps you may want to consider post-paid. The best would be to check with AIS to see what they can offer at Siam Paragon or Central World.

  26. Hi aroimakmak,

    I’m going to Bangkok for 4 days at the end of the month. My friend is going to Changmai the following week and I plan to pass the number to him. Can the prepaid card purchased at Suvarnabhumi Airport be used in Changmai?


  27. Hi Aroimakmak,

    I will be travelling to bangkok next week for 4 days. Planning to get a data sim card which can be inserted into my Mobile Wifi router. Will it work?

  28. May i enquire , if my friend is now in Bangkok, can i get her to buy a 1 month data sim card for me and activate now but my departure will be 6 days later which is on the 21th Oct 2014. Will the card still be in used? If Yes, may i know , must i still need to activate the card again and can be used for 1 month? how much is the card cost?

  29. May I check where is the location of the store? Is it located inside the arrival hall or outside the arrival hall as I check from my friend, my friend says is inside the arrival hall. Is there any other ways to buy the card at the airport as she is out of the arrival hall already and has no access to enter.

  30. Hi there,

    I will be in BKK for few months. I want to get a prepaid sim card which I can use for internet, local and foreign calls, sms, skype and FB. And which I can top up conveniently at any convenience store.

    Which sim card can you suggest? Thanks .

    1. I believe the most value for money sim card now is the tourist SIM offered by the various telcos at 299 baht but it lasts only for 7 days. If you are there for few months, do check with them what they offer. In terms of value for money and reception, I prefer AIS for now.

  31. I have a Huawei mobile wifi (MiFi) device. Can I purchase a AIS Traveller SIM and put in into my MiFi. I will use my mobile autoroaming as it would be easier for my business, and I tether onto the MiFi. Will it work in BKK?

    1. I personally have not used it but it should be able to work. It works as per normal sim card. For actual usage, you will have to check with the telco on the compatibility.

  32. Prakash Here frm India. I am travelling to Pataya and Phuket for a total of 7 days. I need to buy a prepaid SIM on arrival for my iPhone 4. I only need to have a voice card(no internet). How much it will cost and what will be the chaarges for per minute. Plase reply

    1. Hi Prakash, i believe you have already gone to Thailand. My query is also similar to you but didn’t get response yet from this forum. Will you be able to help me on this? Can i have your contact number so that i can directly talk to you. In case you would like to talk to me, my number is +91 9830400788.
      I will be going to Thailand on 9th Jan 2015. So your assistance is needed on priority.

  33. Hi, i am travelling to BKK next Sat for 6 days. Am wondering if AIS Traveller SIM is also good for google maps? Just in case I’m lost and I’d need google map 🙂

  34. Hi Aroi makmak,
    I’m traveling to Bangkok for a week. I plan to get a Sim Card, what will be the cheapest Sim Card suggested to purchase? As I don’t necessary need any mobile data, I just want to get a Sim Card for any emergency call usage in BKK instead.
    Is there any cheapest Sim Card I should I get?

  35. Hi Ariomakmak,

    Thank you for the clear info. Really useful for tourists. Have one question. I will be buying two DTAC sim cards (299 baht) for 2 of our phones, but for my iPhone 6 plus I want to use my mifi. Can I buy another Happy Tourist card and use it in the mifi unit? Or is there any other data sim needed for the wifi unit? Thanks in advance.

    1. I personally have not used their cards in mifi so I won’t be able to confirm the usage. But from my understanding, it should work properly. Perhaps you get one to try it on your mifi first before proceeding to purchase for your other phones. 🙂

  36. Hi, just want to check with you, are all these sim cards work country wide in Thailand? If I buy a card and use in BKK, can I use it when I travel to Pattaya, Chiang Mai and Hua Hin?

      1. Thanks Aroimakmak.

        Just to be sure, there are no extra charges for making/receiving calls no matter where I am in Thailand?

        And also for data charges, they are the same no matter which part of Thailand I am in?

  37. Hi,
    Where in Khao San area (Bangkok) or in Pattaya can I buy a prepaid card for 30 days?
    I need at least 2 giga of data (of course calls and more data will be welcomed).
    Whats recommended in terms of price and coverage across Thailand?

    Thank you!

    1. You can get it at 7/11 or Family Mart easily for 7 days. However for 30 days, it is better to go the the telco shop located at Central World or Siam Paragon. I personally prefer AIS.

  38. Hi Ariomakmak,
    I will travel to Hua Hin & Bangkok – 6 days 5 night in end of December, which telco is the best offer? I am heavy user. I will be using Samsung Note 3 LTE. Thank you

  39. Hi Aroimakmak, Is there any shop in Don Mueang airport that we can buy a data simcard for 7 days?
    Noted from all your comments above the only place is to purchase Dtac Happy Sim Card is only 7-11, is that true? No other telecom shops located there? micro Nano sim available at 7-11 stores too?
    I am travelling this Sat and will be my 1st time arriving at Don Mueang Airport.
    Appreciate your advice. =)

    1. Yes, you can only purchase it at convenience stalls as there is no telco outlets there. Usually Nano SIM card are lesser in quantity probably because of the high demand of iPhone users.

  40. Hello Aroimakmak,

    i will be visiting bangkok for 5 days, then going to Atthutaya and hua hin for 2days each . does the data plan include all the areas? any Recommendations? thanks 🙂

    1. Yes, it includes. I’m currently working on a Guide for Hua Hin, probably will be released in January. Meanwhile, you can check out the Instagram account for places to go in Hua Hin. 🙂

  41. Hi There, i am coming to Thailand on 9th Jan 2015 and will be staying for 8 days till 16th Jan 2015. I am looking for some cheap ISD plan to call to India from Thailand. Need your assistance in this case. During my stay in Thailand i will be travelling to Bangkok, Pattaya & Phuket. Will i get the outlets in everywhere?

  42. Hi!

    I am going on a 6 day trip to BKK!

    Do I have to jailbreak my iphone 5 so as to use the sim card? And to my understanding, as long as you buy it at the ‘official’ shop counter itself (instead of convenience shops etc) they will help you insert and connfigure it?

    Thank you 🙂

      1. Hello- Quick question. I do not have an iPhone. Will SIM card from DTAC/AIS work with an Android phone?

        Thx in advance.

  43. There are no telco provides in Don Mueang. You can only get it at convenience stores.Yes, you can use as long as your SIM card is valid till that period.

    1. Hi Shiyu, you can get it done at the following places:

      AIS: Siam Paragon (Lvl 4), Central World (Lvl 4)
      dtac: Siam Paragon (Lvl 3), Central World (Lvl 4)

    1. Thanks! Yes, no other choices for them but to go for True unless they know how to get at convenience stores or outside the airport. 🙂

  44. The latest update, DMK has truemove now, but pls expect a long waiting time. You can still get it from convenience store too.

  45. It is unlimited for 7 days. Just that the first 1.5 GB will be high speed and thereafter will be at slow speed of 64 Kbps

  46. I’m not that sure. My feel is that it’s not possible as you will might need the staffs to assist you to tag the cards.

  47. Hi,
    I am at Sukhumvit Soi 5, Bangkok, Thailand, and I am having a hard time finding a SIM card. None of the 7Eleven are selling them, and i don’t know where else to look for them. Plz need immediate help.

    1. That’s wierd, seems like their sales for tourist SIM have sky rocketed. You may consider visiting the telco shops at Siam Paragon, Central World or Emquartier to get the SIM cards. All 3 telco, true, AIS and dtac will be able to assist you.

  48. Hi, i will be going Bangkok next week for 8 days, so may i know how much the 15 days prepaid data sim card with unlimited data and free 100baht worth of talk time will cost? and also which 1 do you suggest it will work better (AIS/DTAC/TRUE MOVE H)?

  49. Hi, i will be going to bangkok next week. But i will be there for 8 days. May i know how much will the prepaid data sim card cost? And also which carrier would you suggest me to get?

  50. Hi! Are the AIS SIM cards available in nano sim size? And if I were to get the group sharing package, is it possible to get SIM cards of different sizes (2 nano and 1 micro) since my group is using phones of different brands? Thanks!

  51. Hi! Do you advise to get additional overseas wifi router, if we are getting the AIS Sim card? We are only going for 2 days. Thanks! 🙂

  52. Hi, im going to bkk the week after, may i know if i get the AIS sim card from Changi Airport, do i need to do any setting for my iphone to use the AIS simcard when i arrive at BKK airport?

  53. Hi! Thank you for the article. I am leaving for Bangkok next week (not the first time but my last was about 8 yrs ago). I’ll go buy simcard when I arrive in Bkk so that I can commute with Grabtaxi and Uber whenever necessary conveniently.

  54. Hello! Those are some great information. thank you! I want to ask if you would happen to know other SIM cards that have more data available at higher bandwidth than the current AIS one at 1.5gb?

  55. You can too. Yes, it’s not available at Don Meuang. Depending on where you stay, there are AIS stores at Central World, Siam Paragon

  56. Hi will there be note 5 mini prepaid sim card at the airport? I really need to know cos the sim card is not the same size as note 3. Please help

  57. Hi there
    I have a different questions
    I will be working in thailand as an expat in thailand. I need to update my mobile phone number to my banking account in malaysia.
    -can I reuse my travel sim card for my next travel?
    -was there expiry date for the travel sim card?
    -my passport number have been registered on the sim card, is it save to reuse it back?
    – can I use my travel sim card as permanent usage?

    I never call to cancel my card…. I just let it be and place in my drawer.

    Please advise

    Thank you

    1. for SIM cards there will be an expiry date, usually after 6 months of purchase. it will be better for you to check with the telco on your questions.

  58. Hi, you mentioned that the price is 299bath. what is that 129 and 199 bath the sales person at convenience store showing? thanks

    1. It varies, you have to check the packaging to find out. Some of them do not include data and just comes with 100 baht of value. While some may have limited data.

  59. Hi, If i from dmk i booked a grabtaxi to siam area, it’s only around 200 baht? do we need to pay additional charge cause its from airport?

    1. depends on traffic condition. it should be around 200-300 baht. For booking using grab taxi there is additional charge of 25 baht. if they taxi goes by tollway (to avoid jam), there are additional costs.

  60. hi, i will arrive at dmk and is trumove traveller sim still available? do they have any option for nano and micro simcard?

  61. Hi there,

    Like to know cos im goin for a 3d2n , so isit worth to get the data sim card? or do they sell plan tt less then 7days ?

  62. Hi. Instead of waiting a long queue at the Suvannaphum airport to get sim card, I highly recommend everyone to get it at the Airport Link Phayathai Station at “Thai Sim” store instead (if you are planning on taking the train to city centre). The service there is great and they provide all 3 service networks as well. You also get stuff that the kiosks at the airport do not give you, such as the free map of Bangkok or duty free discount coupons.

  63. Sorry, I’m not sure about that. You will have to check with the staffs at information counter as there’s no information on their website too.

  64. AIS available in Don Muang airport. I heard that AIS coverage is slightly better compare to the rest as i plan to go to Khao Yai.

  65. I hear that if I buy a DTAC SIM online and then go at the airport to pick it up, I will avoid the queues of people waiting to buy a dtac sim. Is this valid ?
    Also, does DTAC allow tethering? ( I want to put it in my iphone 6 and use it as a mobile hot spot, so I can browse the internet from my other devices)

    1. I’m not sure about that because the all queues at the counter are always long. However I know that they have a self-service machine which allow you to buy the SIM Card. Yes you can use it as a tether.

  66. I do not carry a dual sim handphone. can i use a thai local sim card in the handphone and yet still maintain my Singapore mobile number when calling and watsapping?
    How is this possible?

  67. Hi! I’m planning to stay at Udon Thani for 15 Days and will be landing at DMK, is it better to buy Dtac or True Move? I heard True Move connection is not really good in small cities or rural area. Is there any package that serve more than 7 Days? Thank you!

    1. all telco have packages for more than 7 days actually. there are options of 15 or 30 days too. my experience with the various telco is that each has it pros and cons and majority of them usually won’t have good connection in rural areas.

  68. hi, read that there’s a new Traveller Group Sharing SIM by AIS.
    is it available at Suvarnabhumi airport? can’t seem to find any information on that.

      1. Hi, i checked the website and it seems that AIS no longer have the group sharing SIM card. Can you please confirm this if you have the info?

  69. If I purchase the SIM in Singapore, can I activate it first or do I have to wait till I am in Thailand before I can activate it?

  70. It depends on how many of you will be using the internet. If it’s just you alone, a SIM card will be sufficient. If many of you wants to use the internet then the mobile wifi will be a better choice.

  71. Hi, it really depends on your usage and the number of pax. The SIM card has high speed up to 1.5GB and it will become slow speed thereafter (which is almost not usable).
