After a fortnight of weird mobile phone behaviour, I rank OneTel, and got straight through to a man in a call centre in India.
My heart sank. How would a man such a long way away understand? How could he hope to explain why, in order to get text messages I have to leave the flat and walk five minutes up the road, hanging around on a street corner waiting for my mobile to ring like a guilty husband?
I was wrong. "Ah, sir, it's easy to explain - we've given top priority on our network to emergency services since those bombs. I see you live at the top of Tavistock Square, next to a police response unit, a fire station, and just by a University College hospital. That will cause your problems."
