@georgeiordanidis Have you checked for any networking issues near you via here services
https://giffgaff.com/coverage-and-service#network can you please pop your full postcode in here to check for any network issues if shows none please try a manual roam as explained here http://is.gd/manualroam
or switch on and off your airplane flight mode a few times to refresh your network again
Or try a soft reset by holding down the power button and up and down volume button at same time until phone reboots its self and see if works then
If still have issues after that inquire with the agents click on calls texts and data issues then use the how can we help box and explain the problem contact the agents
remember allow from a few hours up to a maximum time of 24hrs for agents replies which will show here when logged into your account
Remember agents work from 8am until 11pm daily
@georgeiordanidis Hi, Assuming that you have tried the basics with your handset like checking the sim card is properly positioned and tried turning it off and back on.
I suppose you should check out the service in your locality
That is the first thing then if your service reports OK then you can go on to more involved methods like a manual roam.
Also it's worth checking that the sim is still active, which would not be the case if you had not used the account for six months.
@georgeiordanidis Hi welcome to giffgaff and the community
• You can check here to see if there is any mast problems in your area here ⬇️
• If the signal is good try doing a manual roam. ⬇️
Or here ⬇️
• I would also try taking out your sim out and trying it in a friend / family members phone that is unlocked and working to establish weather or not it is the sim
I hope this helps👍🏻
