Long-Term Rentals

Keep the same US number for 3 to 30 days to receive SMS from one service, with optional auto-renewal and re-rent after expiry.


For ongoing SMS from one service over days or weeks, on the same number.

  • Durations: 3, 7, 14 or 30 days (availability varies by service)
  • Use case: keep one number for repeated messages from a specific service
  • Always active: the number receives messages for the whole rental period
  • Cancel window: full refund if you cancel within 60 minutes of purchase and no message has arrived yet. After that, the rental runs for its full term
  • Clear messages: clear your message history at any time without losing the number
  • Change duration: picked the wrong term? Open a ticket with the order ID and the duration you want. The team can upgrade it to a longer term, added on top of the current one

Auto-Renewal

Turn on auto-renewal on the number's page. When the term ends, the rental renews for the same duration at the current price, paid from your wallet balance. If your balance doesn't cover it, or the number can't be renewed, auto-renewal switches off and the rental expires. You're not charged.

Re-Renting After Expiry

An expired number can sometimes be rented again with Re-rent same number, at the current full price, as long as the carrier still holds it. It isn't guaranteed: to keep a number without a gap, turn on auto-renewal before the term ends.
