Dear,
I got Samsung Galaxy S3 from eBay...Earlier it was on Verizon network. Guy sold me saying it is UNLOCKED and I can use GSM (T-mobile SIM card) in it. It is not taking SIM card (Invalid SIM error message while boot up). I checked APN and vzninternet service has been stopped and I am trying to enter new APN (T-mobile).
Not even able to enter New APN. Will you be able to help me dear? I tried the method you mentioned. Somehow it is not working for me.
Thanks in advance.
Thanks
Sonu
