Compare the use cases
- Choose one-time activation for a single verification when no later access is expected.
- Choose a rental when an account may need recovery, another login, or repeated verification during the term.
- Consider full rental when several supported services must send messages to the same number.
Limits to keep in mind
A service may reject a number even when it is available in the catalog.
Availability, price, and supported senders depend on the current catalog.
