Checking the gateway after an Android restart
Implementation scenario · This is an example implementation, not a story about a named customer. Results depend on your integration, phone, network and carrier.
AI-generated scenario illustrationThe problem
After a restart, verify that an enabled gateway resumes. Manufacturer settings can change normal Android behaviour.
Build the solution
Check the current app version, permissions and auto-launch. Restart the test phone, wait for networking and inspect last-seen time in the dashboard. Then send a test to your own number and verify the result.
Check before launch
Do not just open the app, which can hide an auto-launch problem. Test reboot separately from force-stop, which requires manual opening.
How SIM Bridge works
Your backend creates a job through the API, and the connected Android sends SMS through your SIM. Store the message ID in your system and receive status changes through a webhook. A queued job is not yet a sent message: the phone must be available and the carrier must accept it.
Start with your own test number. Check Android permissions, screen-off connectivity, retries with the same Idempotency-Key, and unknown-status handling. Keep API keys out of browser code and public repositories.
