❌ 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.
