I just requested for a new number and I have got the new number from giffgaff but now I have no service? Any help please
How long ago did you request your number change?
I ask as it can take upto 4 hours to fully complete (doesn't happen between 9.30pm and 4.30am).
Have you tried rebooting your phone every so often to see if it helps?
give it time @farah173 restart your phone at intervals till connected again
please see here https://giffgaff.com/dashboard
does it show your goodybag/credit etc?
try restarting your phone
