Is the verizon Motorola razr xt912 capable with sprint mobile?
Or any other non-contract phone previders?
well if you unlock it, you can; there's tutorials on youtube on how to unlock a phone.
It should be compatible. I believe they both use a CDMA network.
Unfortunately, it is not that easy for the Verizon Motorola razr xt 912 to work with sprint mobile. This is because of compatibility issues. However, if you unlock it, it would be able to work.
