SIM cards and top-ups are available widely in Thailand from the major carriers (the big three: AIS, dtac and True Move H) as well as a number of smaller 'boutique' provides that lease government bandwidth and equipment or MVNO (such as iMobile or Tune). Purchase of a new SIM card/number is easy, and can be done at operators' shops and any 7-11 as well as at many airport kiosks. Thailand is beginning to require SIM card registration and the production of ID (such as passport for non-Thais) may be required.
Arriving at BKK (Suvarnabhumi) airport in Bangkok, you have the best choice. The 3 major players have their flagship stores in the arrivals hall almost side by side. So you can check prices and compare promotions. All carriers give out monthly promotions which are not mentioned in this article. The situation at DMK (Don Mueng) airport, Bangkok's budget airport and regional airports is different as only True Move shop is on location, but several small shops sell the tourist SIMs of other carriers (AIS/dtac). In Chiang Mai and Phuket, you may find True Move SIMs given out for free.
Concerns for all providers Edit
All of the big three operators do stock all SIM card sizes from normal, micro SIM to nano SIM. Normally the micro SIM card can be popped out from the normal SIM card but the nanoSIMs are often sold separately. It is advised that you request to the staff that you want which SIM card size before you buy.
All of the operators also allow tethering. All of them treat all data going through their network equally therefore your plan would include tethering by default to be used and shared to your other devices. If you are using an iPhone, you may need to perform a network reset or a carrier update for the mobile tethering option to appear.
For voice calling overseas heavily reduced rates as low as VoIP providers are offered by the three majors using special IDD codes. Let them give you the cheapest option for your destination which has to be dialled before the country code.
Topping up Edit
Adding credit or airtime is quite easy in Thailand. Airtime gives both validity and ability to make calls or subscribe to data packages. A few physical places where you can topup: 7-Eleven, Family Mart, BigC, Tesco, phone kiosks and the outlets of the Telecoms.
Adding credit online is also quite easy and there are a few options. MobileTopup.com accepts Visa and MasterCard as well as local debit cards and works on a mobile device. If you have Bitcoin you can topup at http://bitcoins.com.th incurring conversion fees, and if you use Webmoney you can do it thru wm-thailand.comFrom outside of the country mobile you're best bet is to pay online. MobileTopup.com has a reoccurring billing option that is quite useful for this purpose.
Expiry policy Edit
You have to top up a Thai SIM card every 45 days or pay to add validity to keep it alive as well as one call or SMS activity every 6 months. Normally Thai SIM cards expire 45 days after the last top up unless you are able to add extra validity and Tourist Cards sometimes even sooner. So It's hard to keep them alive outside the country, but start-up prices for new starter packs are minimal. True and dtac let you add validity for a price, check this site on how to extend.
Fair Use Policy (FUP) Edit
Fair use is the number of gigabytes you usually see advertised on a plan. Most monthly data plans say they are "unlimited", however they use FUP to say they will give X GB at their fastest speed and once you have used X GB, you will be reduced to 384 kbps, 128 kbps or even 64 kbps. For example: a 3 GB FUP plan for 499 Baht per month means you get 3 GB of data at their highest speed, and then after you use 3 GB your speed will drop. Slow speeds are OK for email and chat, but not good enough for browsing websites.
Over the past years there have been massive changes to all the major operators' networks. Before you purchase any SIM card, please make sure that the network you are choosing is compatible with your smartphones or devices (see below). The big three networks have separate networks operating on more than one set of frequencies. This is often made through domestic roaming on the same network. Operators' new SIM cards usually would roam back to their older networks once you are out of their coverage area (i.e. rural) and you may not not get full speed whilst on roaming. But you should enable (domestic) roaming on your device anyway.
- AIS: only 2G and 3G, 4G/LTE announced for 2016
- old networks (TH GSM): 900 MHz 2G/EDGE, 1800 MHz 2G/EDGE, 900 MHz 3G/HSPA

IDD Calling Rates
Thailand is one of the few countries where some international calls are charged lower than domestic or VoIP calls. For this you have to use certain IDD prefixes. So the correct order to dial abroad is:
<IDD prefix> <country code> <area code> <local number>
The prefixes differ between operators and are added at the end of each section. The major providers give out special discounted prefixes on which major landlines in Europe, America, Asia and Australia can be called for as low as 1 THB per min.
Under a new law all SIM cards have to be registered as of July 31, 2015. Be prepared to show an ID at the point of purchase from now on. You can check your registration status by dialing *151#.
AIS (1-2-Call, you! Mobile) EditAIS has the largest network with almost 50% customer share. It's part of the SingTel Corp. that also owns e.g. Optus in Australia and SingTel in Singapore. AIS is the only major provider in Thailand not to offer 4G/LTE yet. This is announced for 2016 on the 1800 MHz band. AIS operates two different prepaid brands called 1-2-Call and you! Mobile.
You can get their SIM cards online to be sent to a Thai address and at airports, major shopping malls, telecom stands, in AIS and Telewiz branded stores (shop locator in Thai with map). Change language of their messages to English by pressing *700# <call> and choose option 5.
Top-up, balance check and validy Edit
Top-ups can be done in many ways. But ATMs and internet banking require Thai bank accounts. So topping up by a top-up code slip or cash card is recommended. They are sold all over at convenience stores such as 7-Eleven, Family Mart, Tesco/Lotus, Big C or online. Every AIS store has a "payment kiosk" that is an automated top-up machine as well.
Top-ups up to THB 150 are valid for 30 days, of more than THB 150 are valid for 60 days. In case there is no usage or no top-up for 90 consecutive days, with no remaining validity, the number will be automatically terminated.
To top up by code, type *120*<16 digit voucher PIN># and push call button. To check account balance and validity, type *121# and <call>. Check data balances by *121*3#.
1-2-Call SIM cards are their regular prepaid voice and data cards. They are sold as different starter packs (for all prices add 7% tax) for THB 50:
- Freedom SIM: is their usual prepaid card. Be sure to get 3G SIM card. They include 15 THB call credit in 30 days and 100 MB valid for 48 hours.
- Facebook SIM: for social media. It includes unlimited Facebook, LINE, Kakao Talk and Whatsapp, if you top up at least THB 100 per month. Change from other tariffs by calling *777.

Tune Talk (on TOT) Edit
Tune Talk is one of the first MVNOs in the country. It started in 2013 and targets visitors, youth and professionals. It uses the network of state-owned TOT. Tune Talk is affiliated to AirAsia and the most accessible MVNO for tourists on the TOT network.
Tune Talk is a MVNO on the TOT network in 3G on 2100 MHz only. So for using Tune, you need to have a 3G device on this frequency. TOT network is quite good in the Bangkok and most towns giving very high speeds on DC-HSPA+ as it doesn't have so many users as the 3 private networks. But it's in 3G only, with no fallback to 2G/GSM and still very patchy in the countryside. TOT 3G coverage map
So it might be a good choice if you stay in Bangkok, but for travelling throughout Thailand better choose one of the three major networks.
Where to buy Edit
Their discounted starter packs are available on all Thai AirAsia flights along with the duty-free items. You can ask any flight attendant for this SIM card. Be sure not to get a Malaysian Tune Talk SIM. This is also a way to buy the SIM before landing, as at Don Mueang airport in Bangkok the choice of SIM cards is very low.
The "TuneNet!" SIM is available for THB 99 with 500 MB data at their dealers too. If you only get a "TuneTalk" SIM, you can change to TuneNet! by typing *788# and select "Tune Net".
Top up vouchers are available for THB 50, 100, 300 and 500 to give a valiability for 30 to 90 days. They are sold at Thailand Post, Big C or as electronic top-up at 7/Eleven stores.
Data packages Edit
Data on the TuneNet! SIM is by default outside of packages THB 0.50 per MB. You can choose between these monthly packs to add data by typing *788#:
- 1 GB: 200 THB
- 3 GB: 400 THB
Check data balance by typing *700# <call>. Overuse is charged at the default rate. You can buy a new package for more data anytime.
Further information Edit
- IDD prefixes: 007 or 008, but rates are not as low as True, dtac or AIS
- APN: tunetalk /or/ internet
- take care that Tune Talk has a national roaming agreement with AIS. Roaming data are not included in package and charged at 2 THB/MB. So lock device to TOT and disable roaming.
