Why can't some Nokia phone numbers be saved?

1, check whether all the formats of your stored numbers are consistent, and don't store your name in the company column or other places in the address book, otherwise the incoming call information will not be displayed.

Unplug your memory card and try to call you with a different number to see if this situation still exists. If it's a memory card problem, just format and reinstall it.

3. If the above two methods can't be solved, please try to format the phone, that is, restore the factory settings.

4. If none of the above works, please send the mobile phone to the customer service or maintenance personnel at the point of purchase for testing according to the National Three Guarantees Law. If it is a quality problem, it can be returned.
