If your SMS messages are not being delivered, it could be due to mobile carrier rules and 10DLC compliance requirements.
If your SMS messages are not marked as "Successful - Delivered," they may be getting blocked due to mobile carrier rules and 10DLC compliance requirements. These measures help reduce spam and ensure messages reach their intended recipients.
Common reasons why your SMS messages might not be delivered:
1. No 10DLC Registration
To A2P text messages, your phone number must be registered for 10DLC messaging. Without registration, carriers may block your messages.- Ensure your number is registered under a 10DLC campaign. Follow the 10DLC registration guide
2. Non-Compliant Message Content
- Your messages must align with the sample message content you submitted during registration. If your messages contain unapproved content, they may be blocked.
- Avoid adding phone numbers or website links that were not included in your original campaign registration.
- If you need to update your content, you may need to re-register your campaign.
3. Missing "Opt-Out" Instructions
- Carriers require that all SMS messages provide recipients with a way to opt out.
- Include a phrase such as "Reply STOP to opt out" in your messages to ensure compliance.
4. Carrier Sending Limits
- Mobile carriers impose limits on the number of messages sent per day or per minute. Exceeding these limits can lead to delivery failures.
- If you need higher throughput, please contact support.
By following these guidelines, you can improve your SMS delivery rates and ensure compliance with carrier regulations. If you continue to experience issues, contact Notifyre Support for assistance.
