ABSTRACT:
Methods and systems are provided for automatic over-the-air updating of a preferred roaming list (PRL) in a multi-mode device, based on an account association between the device and a wireless local area network (WLAN) access point. For each of a plurality of subscriber accounts, a set of subscriber account data is maintained in data storage, indicating an association between the subscriber account and one or more telecommunication devices. A determination is made that a given subscriber account is associated with both (i) a multi-mode device and (ii) a WLAN access point. In response to the determination, a PRL for the multi-mode device is automatically updated to include access data for the WLAN access point.
