Before traveling, I spoke with Verizon about using my phone while abroad. I told them I would want to get a local SIM card, and I was assured that this was possible because the S3 was unlocked. Now that I have arrived in Europe and bought a SIM card, I keep getting the error message: This SIM card is from an unknown source. I'm unable to use my phone, and I'm so frustrated. I don't have access to a land line where I can call Global Support, so now I'm on the other side of the world with no phone. I tried changing the mobile network to GSM and to Global, changing the available network, restarting the phone, and more. I have no idea what to do. Help?!
