Why does O2 convince themselves they are providing a quality mobile and data signal in my area?

O2 you are not providing a good quality signal to my mobile and data SIM cards. What do I need to do to convince you the service in my area is poor.

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. 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 you with this

Thanks

You could download the O2 My Network app and use it daily to test and send the results to O2 (the app claims to do this every time somebody uses it, keeping O2 aware of how their network is performing), @PasserBy.

The non-app version of this does similar, as documented in this Guide: How can I sort out my network issues? 

Also you could have some issue with the signal in your house because of this: Guide: Do you have poor coverage / signal Indoors? This may help Explain / resolve it - which means, if you have good WiFi coverage in your house, you could switch to using Voice over WiFi, if your phone supports it, @PasserBy - info here: https://www.o2.co.uk/help/network-coverage-and-international/wifi-and-4g-calling

If Voice over WiFi is something you would like to try, you have to be an O2 Contract Customer, and need, as @MI5 posted, to contact O2 to get it enabled on your account - Social Media is a good way to do that, or try your luck calling them around 08:00 any day, numbers here: Guide: Coronavirus Community Help and Support 

All the best, whichever route you choose.

Good luck!
