What it means
What happened
An SMS notification could not be sent because your account has no SMS credit left. Other channels still deliver.
Why
Why it might have happened
- SMS is in preview and runs on credit granted by the operator.
- Your granted segments have all been used.
- A long message can cost several segments.
Next steps
What you can try
- Ask the operator for more preview SMS credit.
- Keep SMS messages short — each 160 GSM / 70 Unicode characters is one segment.
- Telegram and browser push are unaffected and still deliver.
