That is something new to China. Obtained SIM card there easily a few years back, no ID needed. Maybe it's the way the world is going. In someone's eye, everyone is a terrorist, or a 'wannabe'.

What will happen to my DTAC Sim Card after July 1

I have had it for 7 years now?

I will be back in Chiang Mai in September?

So unable to Register while Overseas

Maybe you can send your sim card to someone in Thailand and have them register it in their name. I don't suppose there will be any checlk on who use what sim card.

Well, it depends a bit on the location. I was sometimes able to get SIM card by myself, even without passport, but most of the times I had to produce one. On some occasions they did not even sell me a SIM at all, but I guess that was more a communication fear than a regulation.

On my last job in India we had a local guy organizing all the SIM cards for our Site, after No 27, he got a friendly invitation to visit the local police station !!!
