Dear SIM security list,
Just a quick note that we started tracking the prevalence of USIMs around the world on GSMmap . We feel this is an important security metric given that state agencies can now break the 64-bit keys that older SIM cards produce to encrypt 3G connections .
If no data is available for your networks of interest, please contribute data through SnoopSnitch , an app for many Android phones. Aside from contributing data to GSMmap, the app also displays whether you are using a USIM under 'Network Info'.
