Not experiencing this issue here.

To test, I had one bar signal and got someone to call me with their mobile. Call connected fine.

2 bars signal in my mancave, connected ok from the landline.

I am running 1.54.206.5 firmware\rom. 

Happy to try more testing tomorrow. Get my Mrs on EE to call me on 4G, see how that goes.

Problem solved. I went into an O2 shop and asked for a SIM swap. This has worked. Thanks for all your feed back.
