I am assuming you are trying to use a sim card from a GSM network. This won't work because Nextel uses the iDen network. You will either have to get a sim card from Nextel, or get a different blackberry from a GSM cell provider.

I have a BB 8350 that was flashed from Nextel to Blackberry. We switched our sims cards from my phone to my wife and its back to the Nextel settings. I was wondering do I have to get it reflashed again.


What service are you trying to use? This phone will only work on an IDEN network (nextel,Boost,etc) It can not be used with a At&t or T-mobile. Sorry if the person who "said" they flashed it didnt do it right.

Invalid sim


1. (easyer way) When I got my Blackberry, I had to put it in a couple of times for it to work.

2. Buy a new sim card.
If this does not work, then check to see if it is unlocked.

How can I unlock my blackberry curve 8350i (nextel) to work with boost mobile?


You do not need to unlock the blackberry 8350i to work on boost, you need to replace the service books.  The phone and direct connect will work immediately if you put a boost sim in the phone.  To replace the service books, look here for instructions http://www.howardforums.com/showthread.php?t=1530734

Just follow the directions.  Good luck
