Faulty signal

[Coop]

Been with O2 for years and the signal has progressively gotten worse. Especially so lately. Done all recommended fixes and nothing has improved. Doesn't seem to matter if I'm indoors, outdoors, near a mast or in the middle of nowhere. It's becoming infuriating. I can't run my business properly because of this. The signal isn't even logging at the moment. Even with a full signal icon, it doesn't hold a signal well enough to call or text.
