Just purchased a 8320. Purchased as "unlocked- to work on ANY GSM network". I put in my SIM Card and now it says "Invalid Sim Card - HOME"

What is the problem?

Also, on the upper right hand corner there is a sign of that says "SOS". I have no idea what is wrong.

Hmm - guessing here that it's locked.

If you go to Options > Advanced Options > SIM Card and type MEPD.

This will bring up another screen. If the Network option shows "Disabled" then it is unlocked.

goto status> options> advanced> sim card> then type in mepd does it show active under network?

I am betting you got a LOCKED phone

1. On your BlackBerry, go to Options > Advanced Options > Sim Card.

2. At that screen type MEPD (see note below) on your keyboard. A new menu will pop up.

on a Curve 8300... But it won't type in MEPD? I tried doing that but oddly no screen pops up...

Help... The aliens have invaded my head.. stop.. please..

OK now where do I go to see if my BB is locked?


Ok.. just kidding.. no sleep for 2 days makes one a little crazy!

OOOps.. I forgot what I was going to say..

I got this error right after going to a beta 4.5.0.46... after a scary momment (BB dead.. oh crap) went back to 4.2

This happened to me after I wiped my unlocked device, luckily the buyer I had bought from had the unlock code written down on the inside of the box and all i had to do was imput it again.

actually, only the 8700 series needs to have a SIM card inserted to unlock the device, 8100, 8300, 8800 all do not require you to have a SIM card in the device to unlock the device

I have T-mobile service ...is it possible to use the 8830 world edition from Verizon after unlock it
Also does anyone know where I can download a software that let you unlock it please...please help me

The 8830 will not work in the US unlocked. And no there is not unlocking software. A code must be generated by the carrier or an unlocking service like HorizonWirelessOnline.com - Horizon Wireless, The World’s Cellular Repair Center ß

I do not believe you can use a Verizon phone on T-Mobile since Verizon phones do not take SIM cards.

Maybe I'm wrong as we dont have CDMA networks here in Ireland, but I thought the 8330 World Edition phone had a sim card slot also and can be used on 900/1800 networks, which is till no use to wph27 as TMO use 1900 band
