Upgraded sims but cannot receive or make calls or send and receive messages

[Marl8]

Using my account, I upgraded my SIM card. I noticed then that my data changed to the upgraded deal. I thought however that I had to activate the eSIM card. So I signed out and in again. For security, O2 send a code but I didn t receive it. I cannot make or receive calls nor send and receive messages

 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) , they should be able to help. Or call them on 202 or 0344 809 0202 (contract)

4445 or 0344 809 0222 (PAYG)
