Microsoft virtual numbers for SMS verification

What to know before you buy Microsoft numbers

Microsoft numbers are in stock in 139 countries right now, 131.4M 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. 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.
