Abstract
A server of a wireless operator creates a roaming list based on a user's roaming plan and sends the roaming list to the user's wireless device. The roaming list includes a list of public land mobile networks (PLMNs). When the user travels away from their home wireless network to another geographic area, the wireless device scans based on the roaming list for radio signals. The roaming list contributes to user satisfaction because timely attachment to a radio network while away from home occurs efficiently since the wireless operator creates the roaming list based on both i) roaming agreements that the wireless operator is a party to with other wireless operators, ii) the user's roaming plan, iii) the radio access technology (RAT) capabilities of the wireless device and iv) the RAT capabilities of other wireless operators in particular geographic regions.
