Hi I have a couple of ?? I bought my phone cheap and at the time it didnt have a sim card in it. Well it had the unlock device app on it. When I pushed it it kept telling me device wasnt couldnt unlock. Its through Metro PCS. But today I pressed it and it finally it said device permanatly unlocked. My question is does this mean that it t unlocked for me to purchase a sim card for any carrier? I ran the IMEI number through the blacklist and it isnt on there. I called Metro PCS and she told me yes It meant i could use any carrier. Can you please tell me if and what kind of carrier that is compaitable? Thanks.
