Have you checked the network status here ? O2 Service Status
Is it everywhere or just in one location?
If everywhere, you may need a new sim or have a faulty phone.
If just one location, it may be that O2 isn't the best in that area and a change of network may be required.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
