Getting a local SIM card in Thailand can be a little daunting, not to mention confusing. This article aims to point tourists and expats in the right direction with regards to buying and setting up your Happy Tourist SIM. Many local networks provide inexpensive SIM cards, and many of the principles outlined will work for other networks such as AIS and Truemove, but the information contained herein is specific to the Dtac Network.
DTAC is the second largest mobile phone provider in Thailand, and since January 31, 2015, all SIM cards in Thailand must be registered. This is no big deal and can be done when you purchase your SIM card from either a Dtac, 7 Eleven or FamilyMart stores. You can order one in advance, to be collected at the airport, but this isn’t necessary because they can be picked up almost anywhere. You will need your passport when registering, so remember to take it along with you when buying your SIM.
There are three types that can be purchased:
• 50 baht - SIM card only
• 199 baht - 7 Day free unlimited internet 500mb Max
• 299 baht - 7 Day free unlimited internet 1.5GB Max plus 100 baht credit.
In Thailand ‘unlimited’ refers to the download speed rather than the amount of download allowance you can have.
Failure to register your SIM means you will be unable to use data or make calls. Anyone that has purchased a prepaid SIM card in Thailand, before January 2015, must provide their personal details before July 31st. This does not apply to those people on contracts.
Warning: Some smartphones may ask you if you would like to automatically change its settings in accordance with the new Sim. Tap no and do it manually because sometimes it may change your phone's language to Thai.
