Choose meaningful rows
Start with countries your own application actually serves. For each one, record the expected calling code, sender and registration flow. Do not test dozens of countries merely because a directory lists them. Select a small representative set that covers your real routing and formatting risks.
Keep variables visible
Every test row should identify the application, country, one-time or rental mode, request time, delivery time and result. If a code fails, you can then ask whether the problem was format, sender delay, expired code or platform rejection. Avoid putting actual OTP values or personal customer data in a shared QA spreadsheet.
Use the catalog for execution
Create a separate number order only for an available, authorized route. Check the live price before starting each row; availability can change between test runs. The SMS Activation dashboard provides order status and history to connect the result back to the test case.
Using SMS Activation responsibly
Use numbers only for accounts, applications, and tests you are authorized to access. Follow the target platform’s terms and local law. Availability, prices, supported routes, and payment networks can change, so verify current details in the dashboard before paying.
