When I try & dial out from my contacts it says not registered on network It does this a few times...i try 2 access the number different ways call logs etc & eventually it dials out but there is no direct method. Any advice welcome. I live central & over the last week a notification will flash up every few minutes for no signal too...This is also new..
If you could also try turning your device OFF and take your sim card out, then wait 5 minutes,and turn your device ON again,as this can help in most cases. Also try turning your airplane mode ON and OFF again. Please be aware that the signal checker website is updated hourly, so there may be a current issue that's not showing at the moment,so keep checking the signal checker website over the next few hours or so for any new updates. If the signal checker is showing NO reported issues,can you also perform a manual roam,,which basically is searching for networks on your device. Go to your phone's "settings" and Select mobile network options and Change the Network Selection Mode from Automatic to Manual, and list of available networks will be displayed after a few moments, ( be patient whilst your device starts searching for all the available networks) . Once all the available networks are showing, Select any other network that is not your own network,and After a few moments you will see "No Service" on the display. Now select your home provider(which is O2/giffgaff) network and change the selection back to Automatic,and see if that helps.
