Can I get a dedicated phone number from SMS in the manner of VPS / VDS?

Question

mobile connection

I'm going abroad, I wanted to have a virtual permanent phone number, which will receive calls and / or SMS. With a full-fledged tariff from a real operator (preferably Megafon / Russia), with the ability to control through a browser.
NOT a smartphone virtual machine, but a phone number with SMS support. How it will be implemented on the iron side - I do not care.
Well, and, of course, the service is more reliable.

Answer 1

I doubt that operators take money for using their relay towers, the coverage of one tower is 20-30 km ... You need to use the operators' api, or how to conclude an agreement (although now they belong to a megaphone)
