Appointments & services
Confirming a field technician visit
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
A customer is waiting for a technician while assignments may change. Notifications should follow the team’s confirmed schedule.
Build the solution
After assignment, your backend selects the business phone and sends the agreed window. Schedule changes create a new notification version. An incoming reply can be attached to the service ticket through a webhook.
Check before launch
Keep building access codes out of SMS. Test reassignment, cancellation and several tickets sharing one phone number.
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.
