Question about RIM BlackBerry Pearl 8100

1 Answer

Unlocked Pearl no locking onto network

I have purchased a used, unlocked T-Mobile Pearl and when I put my AT&T SIM in the phone, it will not lock onto the AT&T network. The phone finds the network, connects and then goes back to no network found. The phone continues to search and find the network tehn drop it again.

How do I fix this?

AT&T devices are integrated software and settings necessary to operate on the network. If GPRS attach is not an issue for you then this is likely the problem.
You could go through your settings, such as network provider, connectivity, etc with settings that come default with AT&T devices, however, AT&T will not support an unlocked phone regardless of previous provider. Find someone with same phone if possible and AT&T as provider, try to copy settings, but typically there are some that are view only and uneditable. You could also go to blackberry.com and download the latest version of handheld software onto the device.
If that doesn't work and a new sim doesn't alleviate problem, you are likely out of luck. No one really supports an unlocked phone.

My sim card invalid


The reason that it's showing that your sim card is invalid is because either the sim card has been deactivated already by your service provider, or the most likely cause is that your RIM BlackBerry Pearl 8100 is locked to another service provider. The only bypass for this would be to unlock your RIM Blackberry, or to subscribe to the service provider the phone is locked with.

Hi ive just bought a second hand blackberry 8100 phone inserted my vodaphone sim now says on screen sim not provisioned2 any help please


With that error note, you need to unlock your Phone. It just simply mean that your Blackberry is still operator locked, and would just accept its original operator sim.
There are several ways to unlock your phone.
Unlock by operator- where you will ask for unlock code FROM the original operator where the phone is locked to. Unlock by codes where you will buy unlock codes from sites.Have a search on Google for unlock codes for Blackberry, I cant mention examples, I dont want to be endorsing sites. Lastly professional Unlocking which is performed by technician using special gadgets and softwares.
Hope This helps.

I bought an unlocked blackberry 7230 PDA and I am trying to get it to work. My current cell phone gets a great signal. I got the unlocked phone and put in the Tmobile sim card and everything loads onto the...


Go to Options/Advanced Options/SMS card. Type MEPD, This should bring up a page of statuses. If Network says anything other than Disabled, you BB is still locked


just as a side note you won't see it when you type in mepd, i don't have my bb pearl handy but i believe you have to double tap the keyboard to get the p tho your phone may have the full keyboard
