❌ Error: “No valid phone numbers found.” – How to Fix

When testing SMS API integration (e.g., via Postman), you may encounter the error:

{
  "status": "error",
  "statusCode": "122",
  "reason": "No valid phone numbers found."
}

This error is common among new users and occurs due to one of the following reasons:

✅ Reason 1: Using Demo/Sandbox Mode Numbers

If your account is in Demo/Sandbox Mode, you can only send SMS to:

  • Your registered mobile number (the one used during signup), or
  • Any additional numbers that you have whitelisted in your dashboard.

👉 To resolve:

  • Check if your test number is registered/whitelisted.
  • Whitelist additional numbers from your dashboard before sending SMS.

✅ Reason 2: Incorrect Country Code Format

Phone numbers must follow international format with country code. For example:

  • ✅ Correct: 919876543210 (India)
  • ❌ Incorrect: 9876543210

👉 To resolve:

  • Always include the country code.
  • Follow ITU-T E.164 standard for numbering.

📌 Summary:

  • Use registered/whitelisted numbers in Demo Mode.
  • Always prefix numbers with correct country code.

Once these two checks are followed, the error should be resolved and your messages will be sent successfully.
