A:AnswerYes 99% of the time you can always keep your own number but it has to be in service at the time that you poured it or rather take it to Total wireless if your phone number is not in service it might get released into the into the big pot of numbers you know again you have to have your number working for it to for you to keep it on a new activation with a separate company or your current company.
A:AnswerI don't believe so because they're not necessarily worldwide but they do have calling programs that you could call anywhere around the globe and if you get a TracFone that's usually international compatibility but you might have to get it unlocked but like I said TracFone is total wireless so I'm sure they would make it work for you but total wireless I don't believe has any world phones they do have world calling plans though
A:AnswerIf you can find a retailer that services phones and has it unlocking option then I don't see why not most of their phones have both GSM 4G and CDMA
I'M NO EXPERT BUT WE COULD DO IS COMPARE PHONES AND I BELIEVE AT&T IS GSM NOW RIGHT SIM CARD REQUIRED?
GODSPEED TO THE GOOD STUFF!
