1. A method for configuring a network device according to the identity of a plurality of removable wireless communications devices (RWCDs), the method comprising the steps of:(a) determining the identities of the plurality of RWCDS, wherein identities are based on one or more of International Mobile Equipment Identity (IMEI), Media Access Control (MAC) address, a telephone number, a user account, and a user profile;
(b) determining whether the network device is capable of using the plurality of RWCDs;
(c) retrieving policy settings from an authorized party or a storage medium of the network device according to the identities of the plurality of RWCDs;
(d) determining whether there are conflicts among groups of the policy settings;
(e) determining priorities of groups of the policy settings when there are conflicts among the groups of the policy settings; wherein the priorities of the groups of the policy settings are based on at least one of the following: information retrieved from the authorized party, physical positions of the plurality of RWCDs at the network device, pre-determined settings inputted into the storage medium, chronological order in which the plurality of RWCDs were connected with the network device, and the identities of the plurality of RWCDs; and
(f) configuring the network device according to at least one of the groups of the policy settings;wherein the plurality of RWCDs are plugged to the network device; andwherein the network device provides wireless wide area network (WAN) connectivity through the plurality of RWCDs.
