The invention is based on a platform that has both hardware and software. The latter includes, amongst other things, an algorithm to solve the problem encountered when, on passing between countries and operators, data services have to roam between mobile networks. The invention handles and solves existing technical limitations such as existing roaming logic for switches between operators not taking into account: which services the ‘original’ operator has activated; geographical coverage; different costs for different services; and, whether services other than speech can function in the selected network. |
