Laravel Sms Gateway Troubleshooting: In-Depth Guide

Name the layer before you tail logs

Laravel SMS gateway troubleshooting is rarely “the framework is broken.” It is queue vs JSON vs radio vs wallet. Laravel send SMS. Device setup. Developer Center.

If step one is php artisan cache:clear, you are gambling. Ask whether the job ran, then whether GSM left the tray.

Laravel symptom → owner

Workers that never ran

Supervisor / Horizon must outlive the deploy. Sync ShouldQueue jobs in local .env lie about production. Version your integrations.

A 15-minute triage

1. Confirm the job executed. Failed jobs table / Horizon. A listener that never dispatched is not GSM.
2. Read the HTTP status. 4xx = your JSON/auth. 429 = backoff. 5xx = retry with jitter, not a hammer.
3. Check pairing and OEM battery. Permission denied and Doze look like “Laravel timeout.”
4. Check DLR, not only the log line. Submitted ≠ delivered. Timeout unknown in the UI.
5. Check pulsa and plan cap. Free is 300 SMS lifetime. Developer yearly cap. Operator prepaid is separate.
6. Staff canary on the same code path. Then customers. Do not load-test filters.

Webhooks: webhooks troubleshooting. Load-test ethics: load test carefully.

When Laravel is innocent

Dual SIM still one seat. Multi-device. OTP isolation: OTP verification.

Failed jobs still billed twice sometimes

Service pricing is based on device count and total SMS sent through the gateway. 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. Paid from $19/month. Device and SMS volume pricing. A job that POSTed then timed out may already have queued GSM — idempotency keys matter.

Next steps

Job, HTTP, pair, DLR, wallet — in that order. Then stop reinstalling a Laravel SDK that was never the patient.
