Some SONY smartphones can not be unlocked by unlock codes, because the counter was blocked ("0" attempt left / Counter blocked / hardlocked). In these cases the only thing you could do is to use the phone as MP3 player.
Sigma successfully handles such cases. This is a real solution that we need the most.
Also Sigma repairs IMEI on SONY devices. This is a perfect solution for phones blocked by operator.
People need to call using a phone. Not to use it as a balalaika
and operational log from such counter blocked phone
