Today T-Mobile announced a new type of SIM card that can be embedded into devices for machine-to-machine communications. The new SIM, which is made from silicon, not plastic, is small (the size of the head of a pin), rugged and can endure the elements. The new SIM provides all the same functionality as a standard SIM, but the smaller footprint and more durable design will allow companies to build it directly into their equipment without the need for provisioning and manually inserting SIM cards. The technology is not meant for consumers, but represents a new front for embedded, intelligent wireless devices.

get rid of sim cards

I wish they would get rid of sim cards, that would just about stop the massive world wide theft of gsm phones. If one of my customers has a Sprint or Verizon phone stolen, I call it in and that phone is then dead, good for parts only or by using gps the carrier can tell me where the phone is if it is on. If my at&t or T-Mobile customer has their phone stolen, the thief has a new phone and the customer is out of luck. I think with todays technology they could come up with a better way to allow multi-network multi-technology use without having to remove a sim card, maybe with just an access code and your numbers could be kept on a micro sd. Blackberry has some nice multi-network phones..just a thought..
that is actually not true, if a T-Mobile or AT&T customer loses a phone or its stolen the sim can be killed remotely you do not need to remove the sim from the phone to stop them from using minutes on their account.

gsm trying to be cdma?

the joy of using gsm is you can change networks back and forth with the use of sim cards and compatible globally. a great advantage compared to cdma which totally locks you on the network...

now that t-mobile is planning to put it inside their devices,will they be no different than the cdma counterpart?

i hope they're not trying to phase out sim slot. it's very small to bother them so i think they should just leave sim and its slot alone....
From front page:
The technology is not meant for consumers , but represents a new front for embedded, intelligent wireless devices.

For example, the t-mobile cameo could have a built in sim card that is small...
