This service works like a permanent unlock service.
 I can program the phone for one country u need use only. For example if u need use in Mexico, I program the phone to work in the Mexico carriers.
I can program the phone to work in any country but only for one country. Once serviced your phone only will works with simcard, esim will not work.
I tested and did factory reset, also flashed the phone with new available firmware and phone is still unlocked. 
Always exist risk maybe samsung will patch it in the coming updates. I don't know.
