Key Takeaways

  • Open-source / GitHub SMS gateway projects still need real handset tests — emulators do not exercise OEM SMS ceilings, MMS APN, or carrier filters.
  • Keep a small lab: two OEMs minimum, dual-SIM if you claim it, staging API keys, and staff MSISDNs.
  • Automate API contract tests in CI; reserve radio canaries for a nightly lab job with budgeted airtime.
  • You bring phones and operator credit; platform pricing is devices plus volume when using sms-gateway.app.
  • Link the OSS hub; Free includes 300 SMS lifetime for limited canaries.

You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. Service pricing is based on device count and total SMS sent through the gateway. Pricing. No Unlimited SMS titles for lab guides.

Why emulators lie

Emulators skip modem firmware quirks, carrier SMSCs, and OEM “battery optimization” that kill gateway apps overnight. If your README promises SMS, your QA matrix needs glass and SIMs.

Green CI on mocks is necessary; green SMS on two physical OEMs is the release gate.

Handset matrix

Minimum: one stock-ish Android, one aggressive OEM skin, both on the target operator if possible. Dual-SIM claims need both slots exercised. Pair via setup.

CI vs lab phones

GitHub Actions should not drain prepaid wallets on every push. Mock HTTP for PRs; run a scheduled workflow that calls staging with a tiny allowlisted MSISDN set. Related load caution: load test carefully.

Airtime and keys

Staging keys only in Actions secrets. Budget failed retries. Isolate OTP test numbers from marketing fixtures. DLR: delivery reports.

Lab checklist

  • Two+ OEMs charged and paired.
  • Staff canary numbers documented.
  • Idempotency-Key on lab sends.
  • OEM battery exceptions recorded in runbook.
  • Results archived with app/OS versions.

Next steps

Publish the matrix in your OSS CONTRIBUTING.md. Downloads for the official app: APK. Multi-device: multi-device and dual SIM.

FAQ

Frequently asked questions

Direct answers about android sms gateway open source how to test on real handsets.

Why test an Android SMS gateway on real handsets?

Radio send, OEM background limits, dual-SIM slot behavior, and carrier content filters do not show up in JVM unit tests or most emulators.

Can GitHub Actions send real SMS every PR?

Avoid unbounded PR sends. Use mocked HTTP in CI; schedule limited canaries on lab devices with Idempotency-Key and airtime budgets.

Does open source include free carrier SMS?

You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. Service pricing is based on device count and total SMS sent through the gateway.
