Really bad signal and 5g

[LukeB132]

Since the merger with Vodafone, my signal has been terrible, struggle to make phone calls with 90% of them cutting off saying network busy. And my 5g speeds have been terrible. I'm paying for a service that I can't use

Hey, Luke. 

There isn't anything about the merger that will have impacted network performance. It's likely you're having a local issue, or something else, such as a device or SIM issue. 

I'd recommend using the service status checker to see if there's anything going on locally. If there isn't, it might be worth checking the device and SIM by resetting the network settings from the reset menu, then restarting the phone. You could also try the SIM in another phone if that's an option.
