Key Takeaways

  • wordpress android sms gateway troubleshooting: separate WP config bugs from radio/airtime failures.
  • No official plugin — your glue code is in scope.
  • Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Empty prepaid looks like “WordPress broken.”
  • Confirm live fields in Developer Center before rewriting handlers.
  • Free is 300 SMS lifetime; paid from $19/month.

Triage order

Debug WordPress SMS issues from the outside in: HTTP response → control plane → device → operator. Service pricing is based on device count and total SMS sent through the gateway. Overview: WordPress overview. Webhooks: webhook pattern.

If last-seen is stale, no amount of WooCommerce hook refactoring will deliver the SMS. Fix the phone first.

Symptom → likely cause

SymptomLikely causeFix
401 / 403 from gatewayBad/missing Bearer in envReload env; rotate key if leaked
Accepted but no SMSPhone offline / empty airtimeLast-seen + balance canary
Duplicate SMSRetries without client_refStable order/event refs
Webhook 404Permalink / REST route missingFlush rewrite rules; HTTPS URL

WordPress-specific pitfalls

Object caching stale options, cron disabled on host, REST blocked by security plugins, and keys in the database instead of env. Confirm live fields in Developer Center.

Phone and airtime checks

Battery, OEM kill switches, dual-SIM wrong slot, empty prepaid. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.

Troubleshooting checklist

  • Canary send from server CLI, not only WP admin.
  • Device online + funded.
  • Webhook URL reachable.
  • Idempotent client_ref.
  • No Unlimited SMS assumptions.
