Bought a bb8820 unlocked gsm was at&t put in my sim recognised the sim but won't allow callin my sim is from my nextel i670? can this be fixed


Reinstall your blackberry OS, some models need to reinstall their os after unlocked. If your unlocked blackberry 8820 still have same problem, bring that phone to nearest mobile repair shop and asking them to reflash your unlocked blackberry.

I just unlocked a blackberry 8100 from t mobile to use on the att network and the t mobile sim still works with my phone however when I put the att sim card into the blackberry I get a message on the phone...


It hasn't been unlocked, try again and follow these instructions:

Model : T-mobile BlackBerry Models
1 – On the Home screen, click the Tools icon. The Options screen appears.
2 – In the tools screen, select the Settings icon.
3 – Scroll to SIM Card and select it. You should see the phone number and the SIM ID number.
4 – Type ‘mepd’ to display the first five levels of SIM locking.
T-Mobile uses network locking so the Network should display Active. All other states should display Disabled
Please note: For the Blackberry 7100t you will hit the “P” twice when entering the ‘mepd’ and ‘mep2′ for steps 4 & 5.
5 – Type ‘mep2′ to display the dialog box asking for the unlock code (Press the Alt + 2 key to get the number 2)
6 – Input the Network Unlock code
7 – Press ENTER and reboot handheld.
Model : BlackBerry Pearl 8100 (Alternative instructions if above instructions do not work)
Can be done without a sim card inserted
To Unlock:
1 – While on the home screen, click the “blackberry key” on keyboard, then select “options”.
2 – Choose “Advanced Options”.
3 – Select “Sim Card”
4 – There is no area to type these letters, you just type them as instructed. No need to hit keys twice to get a letter either. Type m e p p d to display the first five levels of SIM locking. Most companies use network locking so the Network should display Active. All other states should display Disabled ( you will not see text appear on screen
while typing )
5 – Type m e p p 2 to display the dialog box asking for the unlock code
(Press the Alt + 2 key to get the number 2) ( you will not see text
appear on screen while typing )
6 – Input the SIM Unlock code
7 – Press in the trackball in once
Your phone is unlocked

You would need to get the unlock code and instructions from a company that specializes in unlocking devices. I recommend HorizonWirelessOnline.com.

I have a blackberry 7290 how do i reset to factory setting


You need to get it unlocked either by doing a search for unlocking blackberry 7290 and paying one of the online services.

Service providers will unlock their phones as well just tell them your traveling abroad and you need to unlock the phone. Otherwise if it is not affiliated with a service provider you will most likely have to pay someone to get you unlock code.

Is it locked to Rogers?


If it is set for one service supplier it should work on that sim - I suspect its locked on another supplier - question the seller on ebay - if he is ingenuine you can always leave bad feedback.

Please rate this assistance - I hope it is useful.
