I've recently returned from overseas this morning, and my phone won't register on XT.
It's been working all through Europe, the Middle East and Australia without issue, and is now only not working in NZ!
I'm with Digital Island, and I've called them. Their diagnosis is a faulty SIM card, but it was literally working 5 hours ago in transit in Australia, and I can make emergency calls OK. They can't have it looked at properly until Monday, but I'm keen to be able to use my phone over the weekend.
WiFi etc. all works fine and I've re-entered all of the APN details without success. No voice or data is available, I just get Android's generic "This SIM cannot connect to the network" message,
Any help would be greatly appreciated!
