<p>A mobile telecommunication device includes a table with rows of entries for use when roaming outside the home country. The entries have an order of preference, indicated by columns in the table. An entry may specify a subscriber identity and/or a local network. When roaming, a device will seek to establish a satisfactory connection using the subscriber identity and local network specified for the roaming country. If a satisfactory connection cannot be achieved, the next most preferred table entry is read. At least one group of entries specifies two different subscriber identities. Specifying multiple subscriber identities and local networks improves reliability by allowing a satisfactory connection to be achieved from another local network, if a specified local network is not available and allows an alternative subscriber identity from an alternative home network to be used if a failure in a home network prevents the establishment of a connection.</p> |
