When I attempt to make a call everything seems to be working but a call is not made, "calling" flashes on screen but no ringing tone.
I can nearly see the mast from hear but the signal goes from zero to max, when I try to select a network I get full choice sometimes but it won't register on my provider Giffgaff. On another day everything works perfectly.
I've done a factory reset and a software repair online.
Ps.the simcard works in a different phone.
Any ideas?
