Has anyone else had this? Last night I noticed my phone had No Service and no bars signal displayed, I live in a very good reception area so thought this odd, went into network and did a scan, it found all the networks, I selected automatic, it registered but still No Service, I went in again, scanned and selected my network, it registered and again still no service, I rebooted the phone, still no service, I then pulled the battery and sim restarted and all is back to normal. Has anyone else had this?

Even I`m facing the same problem. In my case, the service goes on and off for every 10-15 seconds.  I removed my battery and sim and restarted the phone for no good.  If you find a solution please let me know.

I just flew to US from Europe and despite all efforts could not get connected. Phone just remained in 'no servivce'mode and I already considered it to be a roaming issue with my European operator.

Accidentally I dropped the phone on the floor and the battery slipped out. Putting it back, the phone connected itself.

Very annoying situation.

Even I am having the same problem with my Nokia Lumia 710. Tried removing the battery, SIM, restart....nothing seems to help. The problem is not reproducible always because it happens randomly.

Try switching of WiFi...seams to only happen to me when in connected on WiFi

Many people from different Forums and I are facing the same issue. It's definetely a BUG with the Windows Phone + Lumia 710.
I've sent my mobile twice to Nokia Support Center (since it's brand new and stills under warranty) and it came back the exact same way. The only thing they did was reinstalling the OS.
The SIM Card is recognized, if you go to settings and select the Carrier, it will authenticate. I can normally use the 3G data connection (e.g. for surfing the web), but when I go to make a call, send a SMS, it says NO SERVICE!
Common, who's gonna give me a light for this...
I know we may flash the phone, install hacked ROMs, etc... but I just want the phone working. When I chose the phone I would buy, I was not expecting future headaches... I was wrong!
Here (in Sao Paulo, Brazil) the carrier which I use is VIVO.

Suffering from the same problem at the moment. I'm just back from a holiday in Sicily where I had a lot of phone problems and now I can't connect to my provider. I'll try your solution - pull battery & SIM - as soon as I can find my PUK number. Where did I leave it?
