Does it at least display the number of the incoming call? If it displays the number but not the name then chek the following.
The most common causes of caller ID problems are:
- duplicate entries in your contacts, including entries stored on your sim card. This is a problem becuase the phone does not know which name to display and so it doesn't display any. Duplication also includes the same number in different formats. Try searching for a PART of the number as if for example you search for +353 123 456 789, it won't find +353123456789, whereas if you search for 6789 it would.
Having different formats is a problem for caller ID.
- using your international dial code instead of "+", eg: using 00353123456789 (wrong) instead or +353123456789 (right).
- spaces in numbers (some phones, some firmware versions only), eg: +353 123 456 789 (wrong) instead or +353123456789 (right).
- MS Outlook putting "(0)" in number - if you define a country for a contact in MS Outlook it will automatically add a country code and insert a "(0)" in the number in front of the area code, eg: +353123456789 becomes +353 (0) 123456789. You need to remove the "(0)"s
- there has been reports of more than 7 digit numbers causing problems. Some phones may not differentiate between +353123456789 and +353993456789.
