There are two ways to receive SMS codes: a one-time activation and a rented number.
One-time activation
Best for a single sign-up. You get a number for a few minutes, receive one code and the order is complete. It is the cheapest option.
Rented number
Best when you need the same number again — for example for logins or recovery codes over several days. You keep the number for 1–14 days and receive every SMS sent to it.
Our recommendation
Use an activation for quick sign-ups and rent a number for accounts you plan to keep.
