Unknown number?

Hi.

Just installed my replacement sim and it keeps coming up with unknown number.

Any ideas?

We're just customers like you but it sounds as if you need someone to access your account which can't be done from the forum.

You need to contact O2.

If you message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) ,

Thanks.

Contacting 02 would be great if I had all day.

The social media teams do actually seem more competent than the phone support

That's why I gave the social media links. They are based in the UK and do have a good reputation.

O2 replacement physical sims do not carry an embedded phone number.

You will need to manually enter your number in to any phone settings that require it.
