They cheat. The tariff costs 10 manat, and 3 manat room. So they will charge you another 5 manats just like that, for the beautiful eyes of a tourist, telling you that the activation of the number costs 5 manats, and you will be connected to a 5th class of some kind. In fact, deception. They don't give you a check, or documents for the number, or let you sign the contract. Avoid it . This is not an official salon, these are dealers!
