Check the activation first
Check the exact service, country and session expiry in your account. A supplied number and an accepted HTTP request are not proof that the external service sent an SMS.
Use the relevant guide
The guides below separate SMS delivery, temporary-number limits and reward holds. They do not promise acceptance by an external platform or a guaranteed income.
Contact support safely
Use @Smscashorg_bot or support@smscash.org. Provide the activation ID, approximate time and a description. Do not send a complete SMS code, password, API key or private wallet key.
