Dr Markus Kuhn said the SIM could have been replaced a long time ago . He believes one alternative could be typing in a user identifier and password directly into a phone - like we do with Wi-Fi networks . The researchers say they are not sure if this is possible or how it would work, but that there may be other ways to get access to data on an iPhone without having to enter your pass@@ The University of Cambridge lecturer also believes the time is right to switch because of recent advances in cryptographic techniques .
