you also need a data cable, i think they sell them if you don't have one

I put all 0 for the code then hold down menu botton & power same time so it power off. Then turn back on it should work

i had the same prob jsut put a boost sim in it and wait for about 48 hours with the fone on and wit hfull service the whole time they will trace the fone and check to see if it is reported stolen and if it isnt they will unlock it is an automatic program built into the older fones kinda like lojak this should work on about 75% of the older fones out there ok and ps if it is "hot" jsut change the name the fone is registerd to in the fones menu in boost fones it is under my info ok that is all you will need to do

Your phone may state that you need the "special unlock" code but there is no such thing. This issue is rarely solved by powercycling the phone. In many cases the cusomer will have to take the phone to the nearest service and repair center for an exchange.

you cannot use a GSM sim card in a nextel / boost mobile phone, if you need it unlocked for iden service you can go here.

if its locked with a passcode, when it asks for the code, hit the menu button, then enter all zeros, if it still does not work contact the site above for help

No, it won't.

If this phone was originally a Boost phone, it is more then likley on the IDEN network, which is exclusive to Nextel/Boost. Once the new SIM from the company other then Nextel/Boost is put in the phone, it will ask for a special code- thus rendering the phone useless on the new network. IDEN is only used by Nextel/Boost and another company out of the South called southernlinc.

There is no actual "Special Code". The phone is programmed for one, but it won't work. If you can get to a Sprint Nextel repair center, ask them to use RSS to unlock the codeplug. Also note that many Nextel SIM cards will do this to a Boost phone.
