I have a Bell Blackberry 9550 that has been unlocked. I have been using this BB with a Fido sim card for over a week and everything works fine until couple days ago when caller ID displays "unknown number" for all incoming calls. For testing I called my BB from my work cell phone and home phone and both shows up as "unknown number". I then pulled out the sim card from the BB and inserted into my spare phones (Samsung Jack and iPhone) and the phone numbers in the call display show up.
Anyone knows why the BB call display was working previously but now it's not working? I tried turning the phone off and turning it back on but still doesn't resolve the call display issue. I know I have subscription to call display because call display works on my Samsung Jack and iPhone when I pulled the sim card out from the BB and insert into those two phone.

Ok here's additional information to my "unknown number" call display. Today I did a test on my Blackberry 9550 Storm 2 with my co-workers and office phone. Call display on my Storm 2 shows my office phone number so I know it's working. Co-worker A has a Fido phone and he calls me and my Storm 2 shows his phone number. Co-worker B has a Rogers phone and calls me on my cell phone and displays her phone. But why doesn't it shows my home phone and my work cell phone (Bell Mobility)? These are the unknown number on my Storm 2 call display. When I called Co-workers with my work cell phone my work cell phone number comes up on their call display.
Welcome to the Fido technical community,
Your unlocked Blackberry 9550 Storm 2. Could be the cause of this issue. The device was not unlocked properly. Using an unlock device on the fido network will cause caller ID issue.
As you mention, when you place your sim card in a Samsung Jack or an Iphone you no longer have this issue for any number.
We're not able to guarantee Call display on an unlock device.
Unfortunately, this is beyond our scope of support.
