Twilio virtual numbers for SMS verification

How Twilio numbers behave in the wild

Twilio numbers are in stock in 23 countries right now, 1.5M lines in total, and the entry price is $0.07 in Mozambique. 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.

If the first attempt fails, the repair is almost never another number in the same place — it is another country. A refusal at the country level does not change with the operator, and the hold on a silent number is released on its own, so working down the 23 countries in the table costs you time and nothing else.

The reason most people take a number for Twilio is not that they lack one. It is that a personal line attached to an account is a permanent link between the two, and there is no way to undo it later. A one-time line covers the verification step and disappears, which leaves the account without that link.
