Simply the worst. I went to their store in liverpool one last week to buy a monthly paid number, data sim and portable wifi device, the sales person said all I need is an active UK bank account. I came back in a week with my credit and debit cards, and the sales person there told me 99% it is not possible to have what I have asked for, because I have recently opened my bank account, and I have to have my account open for at least a year. He did not even bother to do the checks on his system !!! They never mentioned this on the first time, so I had to come to them twice for nothing . What a waste of time!!! Anyways I got what I want from EE, which has a better coverage anyway.
