I have just spoken to one of the sales team and am not sure if it is me being dim but something seems not right.
He said I had to sign up and start paying today then a sim would be posted out and number ported across which would take about 5 days. This would mean I pay for 5 days of a service that is no real use as a temporary number would not be much use and appear unprofessional. If this is the case I will keep looking at other networks. G
