Phone did not unlock correctly. It just says emergency calls. It took 10 credits and I need them back.

I tested 3 simcards from different co.panied before giving the phone back to angry client.

After I saw no signal I updated the phone to the last version and still the same.

Hi, after no luck with this unlock I updated it to the latest update available from december 2020, and still was in emergency calls, it was recognizing the APN so it already reads the sim, but no signal or data in gsm/umts settings or automatic. Client didn´t want to wait anymore so I gave him back his phone and he left my store.
