Hi, My three Ukrainian guests were handed SIM cards for the '3' network, (valid for 1 month) on arrival in UK. They have since been given 6 month Vodaphone SIMS which they are about to insert/activate. Can they transfer the number they are using on the '3' SIM cards to the vodaphone SIM? That number is on about 8 Government and bank websites, all of which are still in progress for completion. Brilliant support BTW Vodaphone, many thanks.
