Does what it says on the tin cheap calls
I have been with Giff gaff around 2 years now. They do excellent deals for a PAYG sim. Yes network has been down once or twice but its not a big deal these things happen. They have a good online log in system where you can track usage, top up etc. I cant rate the customer service as I have never spoken with them via email which is the only option. However I am glad everything has worked as I shouldn't really need to contact my provider unless the network is down and even in that case there is no need to contact.
