I was with GiffGaff for a short while. Great in the UK but not so good for overseas as data was expensive.I have just ditched Three and gone onto GiffGaff (who use O2).
I had been with Three for much longer than I can remember, most recently on a 30 day rolling contract. Never had any problems during extended stays abroad or at home.
As others have said, I received an email from Three telling me that they were ’putting‘ me on a new rolling contract which DID NOT include ‘free’ roaming abroad (£2pd). GiffGaff (and O2) are still offering ‘free’ roaming abroad.
I wonder when Three eventually realise that they are losing quite a few customers…
If Three ‘put me onto a new rolling contract which doesn’t include ‘free’ roaming they will become history. When moving from Three to another provider is it possible to retain your current phone number
