2 bars and no g4 coverage in my area any more

[Sonja59]

Told every month their is a mast problem but it looks more like my g4 cable has been rebooted ready for upgrade to g5 in my area but it is not helpful when phones call are garbled and connecting to Internet is hit and miss

@Sonja59 See these guides:

Why do I have poor coverage indoors? (o2.co.uk)

If there is an issue with your local mast, there isn't much you can do until the upgrade is completed. O2 normally doesn't give timelines for repairs or upgrades.

In the interim you might try a new sim to see if that helps. You can call into an O2 store if you have one nearby and they'll swap your sim for you. Be sure to bring identification with you.

Alternatively, you can request a new sim from customer service and do the swap yourself: SIM Swap: a mini guide (incl eSim) - O2 Community
