A:AnswerIt is a GSM only phone check with the company. It works great with T-Mobile, AT&T, Ultra, Mint and all other GSM Carriers. NO SPRINT and NO VERIZON!
A:AnswerYes! Although it doesn't work great but then again I only used it in one area where I was only getting 2 bars on a regular basis so it's very possible it works way better when your reception is better
A:AnswerTry to unsuccessfully unlock the phone 15 times. On some devices it will say "one more incorrect unlock and the phone will be reset to factory default".
