A:AnswerYes, this will work on Straight Talk. If you have the AT&T or T-Mobile SIM it should be simply plug and play. Technically it should also work on the Straight Talk Verizon SIM's as well, but some people have noted issues getting it to work properly with the Verizon network while others have had no issues, so YMMV.
A:AnswerYes, it should work just as long as it is an unlocked phone, not cell carrier specific (locked phone}
. You can go to Wireless web site and put the IME number of the phone you want into their cell phone compatibility checker!
A:AnswerIt comes with a small, keylike tool in the white box inside the packaging. Use that to insert into the hole on the top left side of the phone. It is easy to miss seeing the tool when you first open it.
A:AnswerDefinitely, I have purchased 3 for my family members and they all have AT&T. It was a easy transfer. I did it at Best Buy. I even purchased one for my mom's birthday and she was able to go back in and they transferred her information with no problem.
