some stupid question: if a phone does not support any encryption, is it
possible to use it on an official GSM network? (authentication works, of
course) if so, what phone might it be?
I did a quick check, at least Vodafone and T-Mobile here in Germany
reject the Location Update Request with "Network Failure" (0x11) if
they get a classmark without any encryption available. The registration
works with the same phone if the classmark indicates that encryption
support is available. The test was done with a phone where I can
modify the classmark data.
Best regards,
Dieter
