Cannot make/receive calls or texts

[casper64]

I recently purchased a SIM, pay as you go topped up with £15.

However I cannot make or receive calls or texts but I can use my data.

When ever I try to make a call it says "Unknown call" then ends. 

My device is a unlocked S9

I do have texts and minuets on my SIM.

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 4445 or 0344 809 222 (PAYG)

Or you can message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG), hopefully they should be able to help.
