Orange C550 Corrupted SIM contacts

[Guest vokesalex]

Hi,

Very recently i'm finding that all of the contacts stored on my SIM card are becoming corrupted. Instead of the names and details they seem to get renamed as a string of hexadecimal digits.

I.e.

3c3c49474e4f

4163636f756e

The phone numbers for each entry seems to be correct, it's just the name that's being changed for some reason.

This only affects the contacts on the SIM card, not the phone, they remain ok.

I've tried deleting all contacts using the SIM card manager and recopying them over from the phone's contacts but after a few days they revert back to these hexadecimal numbers.

Has anyone else had the same problem, or knows of the solution.

Cheers, and thanks for your time
