Hello!
I sit and think, take for example VK or any other social network. network: they offer free SMS notifications for their users about new messages, etc. I do not dare to determine at least the approximate number of SMS messages that are sent per day, well, probably millions ... The
question is, how? Who pays for it?
Of course, the easiest option is to choose any inexpensive SMS gateway and send, periodically replenishing the balance, but what if the number of users has exceeded 100k. and everyone wants to receive notifications about absolutely everything ... it turns out to be expensive, not the word ...
How to organize free inexpensive SMS notifications for everyone that will work?
UPD:I came up with the idea to connect a smartphone phone to the server, buy a tariff with unlimited SMS in Russia and send) has anyone tried it?

Your thought is absolutely correct. This is how it is done. Only not a phone but a modem. It can also be a phone if it supports being a modem.
You connect several phones, buy an unlimited SMS plan, and send it at a minimal cost.
But you can also have problems with the provider. If there are too many SMS, they can block. Bezlemit is one thing, abuse is another. Therefore, as a rule, they put several modems and distribute the work between them. You can also change SIM cards once a day in one modem.
But this is only if you really send a lot.

I could be wrong, but in my opinion, very fat companies negotiate directly with the OPSOS. That is, they open to them the opportunity to be, as it were, a gateway for themselves.

That is, do you think that VK just figured out how to send messages for free? :)
Simply, the larger the volume, the lower the price.
By the way, if earlier a message came to VK if you didn’t read it for about 10 minutes, now in the settings you can’t send them more often than once a week.

With such a number of users, it is necessary to speak directly with operators.

Free - nothing.
It's just that within the framework of a large service, these mailings cost a penny. Then the question arises of choosing an SMS gateway - price / quality ratio, and that's it.

a modem and a computer will cost you much more than buying SMS from an operator, because. A limited number of modems can be connected to a computer, and as a result, to increase the bandwidth to send SMS, you will need to install additional computers with modems.

VK pays services. Services buy SMS from contractors. Contractors send from their SIM cards.
You can also make such a distribution of one-time passwords yourself.
You buy a phone, SIM cards, install smsgateway24 and send SMS.
