Recently, I changed carriers from Verizon to T-Mobile. However, when I inserted my T-Mobile SIM card into my phone and rebooted, the status is always "Searching for Service" (not just for data, NOTHING works). I've looked on Android forums and they all have instructions for turning the SCH-I535 into a world phone, but that's not what I want. I just want to switch to T-Mobile (do I need to have a "world phone" to do this?)
I've installed APN Manager and tried to change APNs, but entering the details found here
The phone is rooted and not on a stock TouchWiz ROM (I'm using Paranoid Android, a JB ROM)
Why won't my phone recognize the T-Mobile SIM?
