Angry Invalid SIM Card??

Please Login to Remove!

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.

Default what if you do ...

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...


Need help ~!

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

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

Wirelessly posted (Blackberry 8320)

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
