Caller Display problems

[jackbros]

When I first got my xda many months ago, whenever someone called me I would get their number displayed before I pick up. Now it just says "Unknown" and no number. This is an intermittent problem. Occassionally it works, most of the time it doesn't. I have tested this from many phones.

Has anyone else experienced this problem and what can I do about it?

Thanks in advance

If it's the same problem with other XDAs or mobiles, then it's related to your SIM or your service provider network. Call them and ask about the service CNIR (Caller Number Identification Restriction). It's a GSM network parameter for each SIM. I believe that some one has activated this service on your SIM by mistake.

Does that cause a intermittent problem? I thought it would either show caller display or not, not a bit of both or am I wrong?

Cheers

If it's that intermittent, check in different locations ... sometimes it's a location based problem ... as a good practice, replace the SIM in all cases.
