trying to connect to different operators using --3gpp-register-in-operator

In your logs I see a connection attempt with an explicit operator id
(26203) at 1511990328.384995. The logic goes through the manual
registration process, trying to get registered in that specific
network. At 1511990345.704504 I see another connection attempt to the
same operator, that is approx 17s after the previous attempt.

Are you waiting some specific time between connection attempts? Those
two attempts seem too close to each other. You should leave much more
time for the connection attempt to go on, because re-registration in a
different operator, especially when doing it manually, may take some
time. The logs show that the registration in the operator didn't
happen in those 17s, and it looks like the actual COPS command used to
request manual registration didn't reply in that time either. Are you
able to manually reproduce these issues running the AT commands in
minicom?
