I'm capable of sending OMA setting for nokia 6600 using as security method USERPIN or NO Security.
I'm not able to do the same with a nokia 6620... It receives correctly settings if I use as security method USERPIN , but if I don't use any security method it shows me the message: Failed to save received connection settings...
i had tried to do with a example (2 SMS binary messages) in S40 1.1 document but my phone was received: "'Verification failed, settings was discarded". i think, wrong example?
