Intermittant 'No Service' on Sony M2

[Anonymous]

I've had my M2 for about a week and find that it often goes into 'No Service' when the screen is locked. When I reopen the screen 'No Service' can be seen and it then reconnects to O2 within a 30 seconds or so without any intervention.

Hi

Look at your http://status.o2.co.uk

And if you can try your SIM card in another phone as a process of elimination to test the SIM card and your phone.

Bear in mind if acquired from O2 you have a 14 day return window if it is the phone.

That is a strange issue as it sounds like your radio receiver is shutting down when the phone sleeps...
What if any, power saving options have you got set or any power save apps installed at all?

I think when I was playing with the Z Ultra, there was a power saving setting to turns things off like wifi/ data!
Have you tried calling it when it does this?

It sounds like a songs issue or a rogue app to me. It won't be a mast problem. Have you downloaded anything that coincides with the problem you are having?

Not a mast issue whatsoever. As @MI5 said it looks like a battery saving issue. Perhaps turn any off that you may have on.

Also, as @jonsie said regarding apps. Has this been happening always or ave you installed any apps and this started happening? If so a rogue app may be responsible
