Unfortunately they do not have 4 g calling like three do or WiFi calling that's why I left them and went to three as there data speeds were I live are faster than giffgaffs and 02s data speeds. If smarty had same 4g calling and WiFi calling I would have stuck with smarty as it's cheaper than three but am willing to pay more so I get a better service were I live.
I do still use giffgaff but now as a secondary service to three as use giffgaff for work calls and texts and use as an emergency network incase there network goes down then I can still make calls and text people.
