Iost virtual numbers for SMS verification

Buying an Iost number, in practice

An Iost number is in stock in 13 countries right now, 472K lines in total, and the entry price is $0.07 in Poland. The price gap between countries is not arbitrary: it follows what the local networks charge and how often they actually deliver, which is why the table above shows both next to each other.

Every line here is a real mobile number on a real operator, not a VoIP or relay range. That distinction decides more sign-ups than price does: platforms look a number up in the carrier databases before they send anything, and a line type that comes back as internet-provisioned is refused before an SMS is ever attempted. It is also why this catalogue is smaller than it could be.

If Iost answers that the number is already registered, the line has been through it before. Networks recycle their ranges and a recycled line can still carry somebody's abandoned account. Release it and take another: the hold comes back in full, and it is a faster route than anything you can do inside the app.
