Welcome to Vodafone Community
Having had numerous issues in the past, the v3 seems to have been ok, until today when I noticed the mobile had no signal.
Tried making a call ont he mobile as that has "reactivated" the SS in the past but still no signal.
Powered off, waited 30 sec, powered on SS - same as above
Pressed and held SS reset button for 45 seconds, after various sequences of lights over 15 minutes it now has a sold red LED and the first white one slowly pulsating.
Nothing has changed or been distrubed on the internet side, and internet is working fine.
The following Vodafone Help thread maybe of some use.
Especially the 'Issue Not Listed' option that explains how to run a TraceRoute and paste the results back here for one of the Vodafone Social Media Team to look over.
They may need to resync your SS.
