What are good and not expensive services for SMS notifications?

Question

SMS

Hello, I need to make SMS notifications for users.
For example - password reset with a notification on the phone.
Or thanks for registering in the project.
It seems to me that this is not considered a mailing list, but I stumble upon services that are somehow designed for SMS advertising mailings.
So, what are some good services for sending SMS notifications, and not for sending ads?

Answer 1

Some time ago I settled on smsc.ru = this is about good services. I can recommend as an example of a quality product.
But I think there are cheaper ones.

Answer 2

Our company uses the service for these purposes: https://sigmasms.ru/servisnie_rassilki/ The price is adequate, and template traffic for notifications is not very expensive. We send out with a letter name, everything comes through.
