Signal virtual numbers for SMS verification

How a Signal number behaves in the wild

A Signal number is in stock in 110 countries right now, 25M lines in total, and the entry price is $0.07 in United Kingdom. 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.

Price is not the only thing that separates those 110 countries. Local networks recycle their lines at different speeds, so the number of free lines moves through the day — the figures above are read at the moment you load the page, not cached from this morning. And nothing is charged until the code actually arrives, so a country that turns out not to work costs you a wait, not money.

At volume, the same catalogue is readable over the API: one key, a bearer token, and live prices for Signal in any country as JSON. It is the same prices and the same stock the page shows — there is no separate wholesale list — which is what makes it usable for reselling as much as for automating your own sign-ups.
