You can make your phone work with any service using a process called "unlocking". Unlocking is illegal, though, so I wouldn't recommend it.
Apple will sell you an iPhone but you need to have a service plan for the phone to work. People auction off old iPhones on EBay and Amazon has used phones as well. Basically, you can get the phone anywhere but get your cellular service from sprint.
Yes if you buy an iphone and use geohot's black snow and get an international sprint sim
No. The iPhone 3GS is sadly a GSM only phone, so it cannot function on Sprint (or Verizon's) bandwidths.
Yes
Sprint doesn't use SIM cards...
No one can not flash a Sprint iPhone to Virgin Mobile. The main reason for this is because Sprint has always used some feature that lets the user only work that certain phone with Sprint. To better understand the reasoning the best way to do that would be to contact Sprint.
At&t, sprint, and verizon but i would reccomend verizon because at&t and sprint have the worst service
If you have a Mac code to transfer to that different network, then yes.
No. Different technology. ATT is GSM and takes a sim card. Sprint is CDMA and uses internal programming. Completely incompatible.
No because even if it is unlocked sprint works on a CDMA and AT&T works on a gsm signal it's like trying to use AM on FM radio only
Tikl it's free ptt app in the google play store it work great
Yess. It does. Trust me because I know a boy that has one with Page Plus. !
