rasstre - I think you need to use a dedicated service with virtual phone numbers. Here https://sms-man.com/ you can read the description of this service in detail. I like that here you can choose any phone number from different countries. This is a really great solution if you need to register on a foreign forum or website. I was looking for similar services on the Internet, but only on this site there are really low prices for such services.

gate - I also use only virtual phone numbers to register and verify my accounts on different portals. By the way, I'm interested in this service that you share, because the prices on this site are really low.
