Apple and Samsung want to kill off SIM cards
The pair is hoping to develop an electronic version of a SIM that would allow users to quickly and easily change between mobile networks.
The technology behind the e-SIM will be similar to the Apple SIM. This was introduced with the iPad Air 2 and let users quickly switch between data networks on the tablet.
A difference between the two is that while users could remove the Apple SIM, the e-SIM will be non-removable, allowing the SIM card slot to be removed from smartphones.
The GSMA is hoping to finalise the specification of the e-SIM so that it can launch sometime in 2016. The association is confident that a "common architecture" for the e-SIM will be eventually adopted by the telecom industry.
Already, major carriers including AT&T, Deutsche Telekom (T-Mobile), Vodafone, Orange, and Telefónica have backed the proposed e-SIM standard.
