A:AnswerHi, Thanks for your interest. We can't guarantee that device is globally unlocked. It depends on the band coverage and it varies by model, country, and carrier. -Rich
A:AnswerYou probably can, but you should ask yourself if it's worth it for this level of phone. At $219-$299, keep in mind insurance is going to cost you between $8-$12 per month (Up to $144 per year). If you are on a super super tight budget it might be worth it, but otherwise consider the phone "disposable", keep your money and just buy a new one if you break or lose it.
A:AnswerThe unlocked version will - you have to get a Straight Talk Sim card kit. I think you can ask for specific carriers on it too (Att, Verizon) but am not quite sure on that one.
A:AnswerMost SIM cards can be cut from mini to micro to nano if you are handy as well as careful. My galaxy S4 uses a micro SIM that can be cut down to the smaller nano SIM. Search the web for instructions or ask BestBuy for help. I cut my card last time and it worked.
A:AnswerYes, it is dual Sim. But, the 2nd Sim uses the same slot as the MicroSD card. You have to chose between having a MicroSD card or a 2nd Sim. You can't have both.
A:AnswerIt depends how technical / mechanical savy you are. You can do it yourself - there are videos online that show how to do it. Or if you know someone who is. I'm sure there are places that will do it too.
