Mass Phone number Delete...

You will want to go into the Advanced Features option and then to Reset Defaults. This is the place where you can reset the whole phone. The default reset code is 000000. If Nextel has changed it, you would want to contact them to see what the code is, but if it's not 000000, it's typically your 7 digit wireless number. Both phones should work the same way since they are both Motorola. I hope this helps. Thanks.
