How to receive SMS to a Russian disposable number from abroad?

Question

SMS

Question from a friend, then from the first person. From time to time I stumble upon services in Runet, eager to know my cell number. Damn you, here it is - you can start spamming. But there is one more problem, it never occurs to their creators that someone’s cell number can start not with +7, but with something else, and it’s impossible to enter it. Yes, I'm not in Russia now and I don't have a Russian SIM card.
I'm trying to get out of the situation by using the services of receiving SMS to disposable numbers. But there the numbers are all occupied, in all services used more than once. Sadness in general.
Which disposable number services frequently update them and when exactly?

Or, as an option, do any of the Russian operators have SIM cards that do not go bad after three months without replenishment?

Answer 1

sms-activate.ru - and your hair will become white and fluffy... Russian, Kazakh, Ukrainian, American - 148 countries.
I used it myself - I started the box on the gmyle. Gmylo stubbornly ignored Russian numbers, had to register in Kazakh: DDD
Paid. But worth it.
There is registration on VKontakte, whatsapp, viber, gmylo and a bunch of other services

Answer 2

I have to give a banal but effective advice:
one green Russian operator has a tariff for IoT (Internet of things).
He is a priori "long-playing".
