Microsoft virtual numbers for SMS verification

What to know before you buy a Microsoft number

A Microsoft number is in stock in 139 countries right now, 102M lines in total, and the entry price is $0.07 in Netherlands. 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.

Buy the number last. A Microsoft expires its own code within a couple of minutes, and the line you take is held for twenty — a number bought before you are ready has already spent part of its window waiting for you. Have the Microsoft sign-up open at the phone-number step first, then order.
