micha59331 When choosing a network one should check out the signal in their area.
One persons poor signal is excelelnt in a different area and vice versa.
No company provides 100% UK coverage.
A tall building or a large factory between you and a telephone mast can make all the difference.
As @allan1954 said check the signal in your area.
Do you get the same signal level everywhere? Then check your phone - switch it off/on.
Try your SIM in another phone.
As for giffgaff being chancers, they have around 3 million customers like me, who are very happy with the service they get - otherwise we'd all be out of here.
Edit: too many typos 😅
