Well, if you work with a SE embedded in a SIM card, if you change your phone you just have to change the SIM that is all.
When working with NFC using the SIM approach you have basically two options. On one hand you can create applications that communicate directly with SIM to carry out operations with the embedded SE, i.e. recharging the balance of a transportation ticket or just finding out the current balance. >From my experience this approach works well for Blackberry or any other J2ME phone supporting SATSA-APDU API. Android is just another different world, since such low level access to SIM is not allowed from user applications. In this case main processor and baseband firmware must be changed to support a similar functionality already found on several-year-old J2ME phones. This technique has not acquired much market adotion. On the other hand we have the TSM operation. In this case the carriers, who control de SIM and have other means to access remotely to the SIM (OTA), set up TSM services a provide third parties (transportation companies such as RENFE, etc.) a access to SIM (well, actually to a part inside the SE that holds that third party's own applications). In this case the user applications inside the mobile phone do not have direct access to SIM, but they operate with it through a business service that usually proxies to carrier's TSM server.
