Mobile phone problem - How is this possible?

[Alan Medic]

Oldish phone. My OH can make calls to landlines and be heard but not to other mobiles. She can hear people but noone can hear her..........unless it's a landline.

This doesn't make sense to me. Has anyone had a similar problem and resolved it?

ETA It'a working now and I suppose will remain one of the great mysteries

Are you with orange? I have had loads of problems recently randomly my calls not working and other times all fine. I called yesterday and they said they were repairing a few masts in the area which would be cuasing a few problems.

I am with Orange too and funnily enough I thought I was going deaf as, when anyone calls me, I really struggle to hear unless I am in a sealed room.

I am with TMobile and every now and then, when I call someone or I receive a call, it sounds like the other person is a robot or underwater, but they can hear me fine. Doesn't seem to matter what Network they're on so I assume must be an issue with my phone, lasts a few hours then starts working normally again- very frustrating!
