I have Doogee MIx 6/64gb with network-sim problem.
it can't register in any network and there are many networks detected. checked with different sim
Can't call emergency dial.

tested few firmware versions, emmc reset done.

SimProcessor advise appears when reboot (don't know if it helps to diagnose problem)

Any tips how solve the problem? Can I run some tests?

settings > about phone > baseband
but if IMEI is intact then i suspect baseband will be as well.
how exactly did this problem begin?

In about phone---baseband there is DOOGEE MIX 2017.08.18

phone has worked for about 1  month without problem.
with some days of approx, after changes operator sim has stopped to register.
will try to test imei on old nokia phone and tell you if the problem is imei.
