Do you need a city (as the main) number from operators, is it possible?

Question

Telephony

At the moment, after searching with well-known operators, I came across the fact that you can buy an additional city number to the main federal one.
Calls are received on the city and they go to the federal (judging by the description).
But in the opposite direction, when you call, your number is defined as federal.
Is it possible to make the city the main number for popular operators (or not popular ones)?
You need a sim card.
Or maybe someone has already solved this issue differently?

Answer 1

According to the rules for the provision of mobile telephone services (there is such a document), the subscriber is provided with a telephone number of a certain format (with a prefix +79...) For fixed communications, prefixes corresponding to area codes are used. The mobile operator can set up forwarding so that when you call a landline number, they get to your mobile (this is called the "landline number" service). But according to the rules, the operator cannot provide you with a city number for mobile communications. If it does, then it will be a violation, with a further fine from the regulator.
Your option is a GSM gateway (in this case, you are already breaking the law) or a radio extension (hello from the 90s).
There are other (IP-phone) solutions, but in this case there is a connection to the availability of the Internet.
