Try each of these things and see if they work.

1) Turn your phone off for 5 minutes and then restart.  This means powering it down completely, not just turning the screen off.

2)  Check for signal problems or maintenance with your local mast.  You can do that here -

3)  Try doing a manual roam.  This resets your phone's connection to the network.  You can find instructions for doing this here -

If you're still having problems, try taking your SIM out and popping it into a different phone and trying another SIM (from a different provider) in your phone.  This will help to determine if the problem lies with your phone or the SIM.

Hope that helps Smiley Wink

Hi there and thanks for visiting the community.
If you could please try turning your device OFF,wait 5 minutes,then turn your device ON again,as this can help in most cases.If your issue has not been resolved,check the signal in your area,by visiting or clicking onto the link below.
Please be aware that the website is updated hourly, so there may be a current issue that is not showing at the moment. Keep checking the signal checker website over the next few hours or so,cheersSmiley Very Happy.

If the signal checker is showing NO issues,you could also perform,a manual roam,which basically is searching for networks on your device.Go to your phones "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.Select any other network that is not your home provider network and After a few moments you will see "No Service" on the display.Now select your home provider(which is o2) network and change the selection back to AutomaticSmiley Very Happy.

Hi stu
Firstly check you have credit or a goodybag active by dialing these codes from your mobile

*100# Airtime credit balance
*100*7# Goodybag minutes balance

If you do start by rebooting your handset then

Check for mast or service issues

If that's ok try doing a manual roam

When did you activate your sim card?
Have you checked that your goodybag still has allowance on it?? ( if you got goodybag)
If you only have AIRTIME CREDIT make sure theres enough money to make calls, texts. Go to your online account and check your DASHBOARD.
Also check your phones setting if its none of the above. You could also try a basic rebooting of the phone.

Hi Stu, assuming you have Airtime Credit or a goodybag to cover the cost of calls/texts, can I suggest that you start by checking the giffgaff network status in your area to see if there are any local issues.


If the signal is fine, you can try manual roaming by following the link to guide below​/manual-roam/td-p/3345471

That can sort all types of issues!


Would also do no harm to reboot your mobile, if not already tried.

Please don't forget to Kudo if my post is helpful or mark as Best Answer if appropriate, thanks.

Have you purchased the goodybag on an old account you no longer use?
