| I have the Nokia 6263 with T-Mobile, and I get some calls that show up as 'Call'. I just got this phone, and I know that these calls are coming from people whose numbers are hidden, where on my last phone, it would show up as 'Unknown call'. Are you sure that the numbers that are calling you are not hidden? I do not see any settings in my phone that would restrict incoming Caller ID. It might be an issue with your network- you may want to contact your provider and ask them what's going on with it. |
