My number is shown on my account and I have signal, but I'm unable to make or receive calls and texts.
I have checked all the steps to make sure that the problem is with transfer not with my phone. All the settings are correct and sim card is not working on another phone as well.
Hi, was the giffgaff sim working before the transfer or didn't you get chance to use it?
Which phone do you have?
Do you see a connection symbol
(3G, 4G, H, E, gprs)
On your phone keypad dial *100*7# and press call
Do the same with *100#
What word or words do you see on the phone screen?
What do you hear exactly when you call your number from another phone?
