Help!!!
I am a TMobile US customer with a MyTouch4G. I am in Japan on business,
and my phone is only usable as a brick. I enabled international roaming,
but my phone shows "emergency use only", with no carrier connection.
According to TMobile, Softbank supports GSM at 2100MHz at 3G.
According to TMobile, my phone supports that as well.
What do I need to do to get my phone to make calls?
Do I need to have TMobile unlock my phone?? And do I need to get a local SIM card?
