1. Yes
2. You would insert a SIM card of a different carrier and see if it works (and is detected).
3. It will support any GSM carrier which supports its frequencies

[Q] how to unlock galaxy s3 on verizon

I ordered a galaxy s3 Verizon from Philadelphia. I live in Greece and I activate my galaxy with a Verizon's sim that my seller send it to me. I rooted the phone and then I installed the old version of ez-unlock . When I entered my SIM card it says that there is a non-Verizon SIM card. Do I need to restore it and do the process with a different order? Any solutions?

pls help mee with this problem... http://forum.xda-developers.com/showthread.php?t=1899806

No Sim message after using international sim

I have a galaxy s3 16 GB Verizon. After using an international Sim card, it will no longer accept any Sim card. I tried two Verizon Sims, and the international Sim. It would not detect either of them. I did a factory reset. Whenever you eject the Sim, it feels spongy. Stock 4.4 kitkat
