Communications network capable of determining SIM card changes in electronic devices

A system supporting delivery of subscription services to users of a plurality of handheld electronic devices each enabled to operably couple to a user interchangeable programmed card, the system comprising:

• at least one server communicatively coupled to at least one of the plurality of handheld electronic devices via a wireless network, wherein the at least one server receives from the one of the plurality of handheld electronic devices an indication of a user interchangeable programmed card change event, and information identifying the at least one of the plurality of handheld electronic devices and at least one subscription service;
• wherein the at least one server sends to the at least one of the plurality of handheld electronic devices, via the wireless network in response to the user interchangeable programmed card change event, one of information for updating at least one memory in the at least one of the plurality of handheld electronic devices to enable user access to the at least one subscription service, and information for notifying a user of availability of the at least one subscription service;
• where the at least one server determines whether the at least one of the plurality of handheld electronic devices is able to support providing the identified at least one subscription service to a user;
• and
• wherein the at least one server automatically sends the information for updating the at least one memory in the at least one of the plurality of handheld electronic devices, if it is determined that one or more of the following:
• device configuration information, user preferences, and software or firmware of the at least one of the plurality of electronic devices, is not able to support providing the identified at least one subscription service to the user.

A handheld electronic device comprising:

• at least one processor operably coupled to circuitry for communicating over a wireless network and to at least one memory having stored therein executable code supporting a set of services on the handheld electronic device, the at least one processor operable to, at least,
• detect a user interchangeable programmed card operably coupled to the at least one processor,
• send, to a first remote server over the wireless network based upon the detection, an indication of a user interchangeable programmed card change event, and information identifying the handheld electronic device and at least one subscription service, and
• receive, from a second remote server over the wireless network, one of information for updating the at least one memory in the handheld electronic device to enable user access to the at least one subscription service, and information for notifying a user of availability of the at least one subscription service, wherein the information for updating the at least one memory is automatically sent to the handheld electronic device, if it is determined that one or more of the following:
• device configuration information, user preferences, and software or firmware of the electronic device, is not able to support providing the identified at least one subscription service to a user.
