Might be worth checking the following guides, but also trying your sim card in a different phone..
Guide: How can I sort out my network issues?
Guide: Is the network down for me or everyone?
If nothing helps then contact o2 on 0344 809 0202 from another phone or via Social Media; if you send them a message on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG)..
- Xperia 1V - o2 and Spusu
- Pixel 8 Pro - o2 and Vodafone UK
