In the first email I was mistaken about the authentication method in pppd -
it is pap not chap. So, probably this is the problem. How can I change the
authentication method for the context activation in Ofono from default chap
to pap? Where is the best place to do it in the code?

Yours sincerely,
Sergei Golubtsov.
