Free sandbox key, instantly, no card. Sign-up is a human step: there is no API
that creates accounts.

1. Open https://joinsimplesms.com/signup and sign up (email or Google).
2. Copy the test key (`ssms_sk_test_...`) from the console.
3. Every endpoint works in test mode against https://api.joinsimplesms.com/v1, including magic
   numbers for verification. See https://joinsimplesms.com/docs/sandbox.md.
