Signal dropped on Three network

[jazzpianouk]

For some reason the network signal dropped yesterday on my Nexus 5 and I cannot connect to the Three network. It has worked faultlessly for 18 months I tried everything - even a factory reset and no result. I tried the Three sim in a different phone and it worked - I tried an O2 sim in the Nexus 5 and it worked. For some reason the Nexus 5 has stopped working with a working Three sim card. Any thoughts?

Sounds strange, but I don't think it would be the phones fault. I would suggest calling Three and have the phone near by, they will run through all your mobile network settings to ensure nothing has changed.
