Hi @jackshereuk,
Welcome back to our Community Forums! Thank you for your post and I'm very sorry to hear that you're unhappy with the O2 coverage in your area!
You can take a look at the O2 Coverage Checker on our website to see if this can advise on what's happening with your coverage.
Have you been experiencing this issue since you've swapped over to O2? Are you experiencing this problem with most locations you visit, or specific ones?
Please take a look at our Mobile Support page to run some further diagnostics so we can look into this issue further for you. Keep us updated.
Thank you.
