Hi all

I've been attempting to make a phone call from my current location where my iPhone 7 Plus flips between 1 bar of 4G, 1 bar of 3G or no data, but always one bar of signal. The phone will show that it's attempting to make the call but will remain silent for a number of minutes before beeping 3 times and saying 'call failed'.

I've tried restarting the phone but no joy. I'm on the Three network.

Many thanks

M.
