<p>This invention generally relates to mobile subscriber identities for mobile devices, and more particularly, to dynamic assignment of International Mobile Subscriber Identities (IMSIs) to reduce roaming and overuse charges. Instead of using a reprogrammable embedded Subscriber Identity Module (SIM) card for remote activation of a device, mobile carrier charges, such as roaming and over limit usage fees, can be significantly reduced by reprogramming SIM cards dynamically from a pool of available mobile accounts. A smaller pool can be utilized to meet the needs of a large group, rather than a one-to-one association implemented within today's phones. Resource usage can be tracked and as one account reaches its maximum, a new account can be assigned to the mobile device to prevent overuse charges. Existing FMC concepts can insure single number inbound or outbound caller identification regardless of the name or number associated with the SIM card for the mobile device.</p> |
