I have a Nextel sim card in my boost phone i335 I need special. Code

Yes you can use it, but, you need a boost sim card.  Nextel phones work fine on Boost (same network) but you need a boost sim.  You can get them cheaply on ebay, often with the $5 dollar credit for under $10.00.  Otherwise go to a local phone store and get a boost starter kit.  They are made so you can start service with a boost or nextel phone.

Remove the battery from the phone. Let it remain out of the phone for 10 minutes with the phone off. Replace the battery and turn the phone on.

This is a problem with the phone trying to read the SIM card after being in another phone. Be patient. It may take several minutes for the phone to read the SIM.

Sound as though maybe you're trying to use a "boost" sim card on a Nextel phone. The phone has to be unlocked in order for that to work.

I called Boost support about the same issue and I was told that that particular phone and any other Ic series phone by motorola will not work with Boost Mobile. There was also a few other phones that will not work. Try calling thier support line and requesting the list of phones that won't work. Good luck.

if it says sim pin blocked you will need another sim card, go on ebay and get a 5.00 starter kit with IMEI for like 4.50

boost only uses boost sim cards
you cant put in a nextel sim in a boost phone
call customer service

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.

No, it won't.

When you are using a Nextel sim card in a Boost phone, The Boost phone recognizes that it is not the alotted sim and will automatically lock up. This doesn't happen in all cases but it does happen often. There is no way to fix this issue besides replacing the phone, which you can do through warranty if you can not return it to the store.

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.
