Nextel i870 Subsidy Lock Code

its no code just try to dile a number and it should ask you to transfer from dat **** or go to your settings and turn it off

your nextel phone is for an IDEN system and the att is not... don't think you'll have much luck with this.

need to go to nextel for the code

You may need to purchase a new sim card for it to be compatible with your nextel phones BUT it won't hurt to call customer service and try to activate that sim card under the ic902's serial number. Because your ic902 is also a sprint phone it works off of a different network and will need programming. Customer service will be able to activate your phone and give you the info needed to get your phone up and running.

my motorola i870 is asking for a subsidy code.

your son activated the subsidy lock.....it requires special program to remove ...if you search online you will find it

search for raptor....you will also need a data cable
