Caller Line Identification

[Pongo42]

I have been moved from Virgin Mobile to O2. Generally happy, but both my phones will not display incoming numbers - just being shown as unknown number. Is this a known problem and how can it be fixed? Thanks.

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

Give O2 a call on  202 or 0344 809 202 (Contract)  4445 or 0344 809 222 (PAYG)

Or you can message O2 on social media on Instagram https://o2uk.co/O2CIG), Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW).

It is possible the Virgin SIMs you have presently need to be swapped for genuine O2 branded SIMs to resolve this, @Pongo42 - if you feel confident in using 202 or Social Media O2 support for this as suggested by @Cleoriff above, including the wait while new SIMs are mailed out to you, that is fine - otherwise, take both handsets and photo ID to an O2 Shop and ask them to move you onto the correct brand and type of SIM in each device. Good luck!

Thanks for the prompt responses. Visited a very helpful O2 shop in Aylesbury, they replaced the SIM cards and CLI immediately burst into life. Perhaps this experience could help others. transferring from Virgin to O2.
