# What should I do if my messages aren’t being delivered?

1. Check if your customer’s number is valid and opted-in for messaging.
2. Ensure your DLT templates and headers are approved for SMS.
3. For WhatsApp, verify that your message templates are approved and that the customer hasn’t blocked your number.
4. Confirm your wallet balance in **[SMSGatewayCenter](https://www.smsgatewaycenter.com)** to ensure you have sufficient funds.
