    How do I fix this? The phone worked fine overseas and now here in the states I have bought 3 SIM cards from T-Mobile and all give the error. The phone was bought in the states unlocked and sent to me overseas.

    Hate to say it but is sounds like it isnt really unlocked. Mine use to say invalid sim until I got the unlock code from the carrier and now any sim works. If it was bought in the states what carrier is it branded to. Did you buy this from a reputable store?

    Hi, your phone seems to be locked to certain network..so you need to unlock the network..for unlocking , you can use unlock codes..it is very easy..this unlock code is available at many unlock providers . here you need to check for your phone model and the locked network..if it is available you can get the unlock code easily..

    The problem was I needed to do a soft reset. Once that was done the AT&T SIM worked.
