can i use a verizon phone for sprint does any one know te codes?

Answer 1

You can't use Verizon phones on Sprint network. Even though they both work on CDMA they don't function the same way the GSM phone carriers do.

Answer 2

Verizon Wireless & Sprint PCS phones aren't compatible. Verizon Wireless V-Cast Network cannot work on a Sprint PCS Vision Phones they both might be on the CDMA but not compatible.
It would be better to have another Verizon Wireless phone to use on that network rather then a Sprint PCS phone. Sprint will let you take your Verizon Wireless cellular phone number with you but not the phone to their network and visa versa too.
