Check the number and service first
Make sure you entered the assigned number correctly in the service you selected and requested an SMS rather than a voice call. Check whether the service accepted the number and whether the receiving window is still open.
Keep the private SMS inbox open or return to it to check for an update. Do not repeatedly buy new numbers while the current order’s outcome is unknown.
Use cancellation when the inbox offers it. Eligibility depends on the actual order and receiving status; a number that already received a code is different from an unstarted or confirmed no-code order.
If the service rejects the number, the window expires or the status is uncertain, contact support with the order reference and error. Never send passwords or verification codes to support.
