Nano-SIM Decision Delayed 117

judgecorp writes "The decision on the next generation of even-smaller SIM cards for phones and other devices has been delayed by standards body ETSI, and the issue (which should have been settled this week) is nowhere near resolution. Apple wants to trim the existing micro-SIM further, Nokia wants to move to something like a micro-SD card which may involve patents. Meanwhile RIM has complained about Apple's approach."

    My guess is the amount of space they take up in the phone is the problem. Basically, between the SIM itself and the hardware for reading it, that's a good amount of real estate.

    Because without a separate card, you get the Verizon/Sprint problem of refusing to activate devices that don't exist in their ESN database; i.e. devices that they didn't sell themselves at markup on extended contract. The SIM standard at least gives the telcos a (semi?)-secure method of identifying subscribers for billing purposes, while keeping them out of the business of dictating which devices are allowed on the network.

    Tme for all the hypocrites to come out against apple who is offering a free, perpetual license for the relevant patents, in favor of those who won't do the same, only because they have an irrational hatred of apple. Just look at the first post.

    The are offering a 'free' license only to anyone who licenses their patents under the same conditions. That's not really 'free' that's 'Apple is tired of getting charged license fees by people who've been doing phone R&D rather longer than they have'...

    The SIM isn't just a memory card. It also has onboard processing. Not much, but just enough to perform a handshake: The network actually authenticates the SIM itsself, with the phone just acting as a network interface and power supply. That way it is practically impossible to clone a SIM (There are ways, but they are far beyond the abilities of even most specialists in the field). As for why they are used, it's a regulatory thing intended to decouple the network operators from control of the devices, which could be seen as a conflict of interest or as a way to prevent customers from moving to a new operator (If they couldn't just move the SIM, they'd have to buy a completly new device).

    Not really, they are offering the design for 'free' to the standards committee so long as all others with possible patents covering the design do the same. If they get their way, anybody who wants to utilize a the new standard would be free of licensing costs. In no way is Apple trying to get a free ride, they want the ride to be free for everyone.

    Do you have any idea how irrelevant that amount of space is? The standard Mini-SIM is 25x15mm. It's tiny. The Micro-SIM is 15x12mm. It's about as small as it can be without getting lost instantly when you remove it from the phone. The Nano-SIM is 12x9mm. Your phone would save 6x12x0.76mm. A typical smartphone has far more wasted space than that in various places. For applications where that much space actually is important, there is the embedded SIM, which is only 5x6mm.
