Can you use a nextel sim card in a boost mobile I415?

Answer 1

If the phone is unlocked you can use a chip from any service provider. The chip must be the same brand as the people you pay your phone bill to. Like if you have t-mobile then you need a t-mobile sim card, but you can use an unlocked cricket phone.

Answer 2

No, it will give an error message asking for the unlock code. Once you get that error, you screwed up the sim and it will not work in either phone again. Nextel does not have the unlock code, Motorola made the phones that way. Motorola will not provide the code either.
