You may remember that half a year ago Thai authorities issued a new rule requiring all prepaid SIM card users in Thailand to have their personal details registered. Failure to do so means that you’ll be unable to make phone calls, send messages or use data after July 31st, 2015.
The mandatory registration process started on February 1st and, well, the deadline is just around the corner. In fact, as of writing this, there aren’t even 30 hours left to have your personal details registered.
Ironically, your webmaster only just noticed himself that his SIM card has obviously not been correctly registered yet, that’s although a couple of years ago when I lost one of my old phones I had to show my passport at the local AIS shop to retrieve my old familiar number. You would think that’s enough to have your SIM card registered in your name? Nope.
If you’re not sure, you can dial *151# to check whether your prepaid Thai SIM card is correctly registered or not. If it isn’t you better hurry up as otherwise you might no longer be able to use your number from August 1st, 2015.
How to Register Your Prepaid Thai SIM Card
If you’re a foreign citizen in Thailand, the easiest way to register your SIM card is obviously to take your passport to the local store of your mobile network provider. Alternatively, you can also register your personal details at any “subscriber registration point” at Big C or Tesco Lotus, as well as any 7-Eleven store.
Thais will obviously just need to show their ID card to register their prepaid SIM cards.
Note: As the registration requirements have been largely ignored by mobile network providers in the past there’s no guarantee that your SIM card has been properly registered even if you’ve previously shown them your passport and they’ve registered your personal details when purchasing a prepaid SIM card, for example, at a 7-Eleven store.
Again, if you’re not 100% sure, you can dial *151# to check whether your SIM card is registered or not.
As enforced since February 2015, tourists who purchase a prepaid Thai SIM card (which they may never use again in the future) will also have to show their passport at the point of purchase in order to qualify as registered.
So you better hurry up, take your passport to the next 7-Eleven store or (arguably the most reliable option) the local store of your mobile service provider and register your SIM card today! If you don’t, you’ll most likely find yourself unable to make phone calls or use data after tomorrow, and have to purchase a new SIM card. There doesn’t seem to be another grace period.
