I’ve had exactly the same issue. Tried messaging multiple times, 202
several times, another forum and Twitter. The data issue is fixed, but
unknown caller persists. Can anyone help? Please
@O2Sarah - I am having the same issue of no caller ID since changing to
eSIM (and now back to plastic SIM) which didn’t fix the issue. O2
support are looking into this (1453220887), but haven’t got back to me
yet. Can you help, please? Many thanks
