" s1 network unlock enabled for both servers.
that means, users can unlock locosto-based semc phones with "bugfixed mcu"
and neptune-based phones.
to make full unlock user should check both
"signed mode" and "do full unlock instead usercode reset" settings.
first stage (signature calculation) will consume 2 credits.
second stage (unlock) requires at least 1 credit on account, but will NOT consume credits.
service NOT working all 24 hours, so try your luck... "
so I think it is not for free unlock of neptune and locosto phones,new mcu type
