OK phone guys out there. I have a question or maybe a lost cause. I have a Nokia 1200 prepaid phone bought in Thailand, and used on the Thai AIS network. I bought the phone second hand and then just used my existing SIM with it over there. The phone is unlocked, displays welcome screen etc. I got a T-Mobile SIM card and activation kit for it when I can back to the USA, but it doesn't pick up any network signal. I activated the number online with the phone serial etc, but still have no network picked up by the phone. A friend of mine has T-mobile here as well, so I know there is coverage. It's not a great phone, but I just needed a cheap emergency back up. I really don't want to go buy yet another crappy phone when I may not be here long. Any ideas would be greatly appreciated.
