Lots of potential reasons @Fryzmaster
Have you got mobile data turned on?
Do you have the correct apn?
Try resetting your network settings.
Is there a mast down locally ? O2 Service Status
Have you used all your data this month?
Is your sim faulty? Guide: How can I sort out my network issues?
Guide: Is the network down for me or everyone?
If still having problems, you can 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 you with this.
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.
