1. Select the exact service
Choose Sendwave before selecting a country. Availability for another app does not imply that the same number is suitable for Sendwave.
About Sendwave SMS verification
NumFlow groups current countries, line references, and platform prices by target service. Select Sendwave first, then choose from the options currently shown for the account flow you are completing.
The assigned number and received code apply to the effective window of that order. Sendwave may restrict virtual or temporary numbers, so acceptance is determined by the target service rather than guaranteed by NumFlow.
How the Sendwave verification flow works
2. Compare current options
Review the available country, line reference, and platform price shown at the time of the order.
3. Track one order
Use the assigned number within the returned window and keep checking that same order until a code arrives or the order reaches its final state.
Sendwave verification FAQ
Can NumFlow guarantee a Sendwave verification code?
No. Sendwave controls whether it sends a code and accepts a particular number. NumFlow shows current availability and the resulting order status.
Which country should I choose for Sendwave?
Choose a country that fits the target account flow and is currently available. Compare the displayed line reference and platform price before ordering.
What if the Sendwave code does not arrive?
Keep checking the same active order until its returned expiry. If the order becomes cancellable or expires without a code, follow the status shown before retrying.
