It is more than two decades since mobile phone technology started its journey, and it is growing stronger, faster and smarter every day. We have seen many philosophical changes in the network designs. However, some basic things, like subscriber identification process and SIM card design, have changed very little – philosophically. Networks still use a relatively large physical SIM card to identify a subscriber. In an age, where an average consumer is expected to have multiple’ web enabled devices’, each device is identified by the network as a separate subscriber gadget. But, these philosophies seem to be challenged by a few recent technological innovations.
