Telnyx is a leading provider of SMS Communication APIs, designed to facilitate seamless messaging services for applications. It offers robust solutions for sending and receiving SMS globally, ensuring reliable and efficient communication for businesses.
One common issue users encounter is a delivery failure, where the message does not reach the recipient's phone. This can be frustrating, especially when timely communication is crucial.
When a delivery failure occurs, you might notice that the message status remains undelivered, or you receive an error notification indicating the failure.
Delivery failures can happen due to various reasons, such as incorrect phone numbers, network issues, or restrictions on the recipient's device.
To resolve delivery failures, follow these actionable steps:
Ensure that the phone number is correct and formatted according to international standards. For example, use the format +1234567890.
Confirm that the recipient's phone is on and within network coverage. You can ask the recipient to check their phone settings or try contacting them through another method.
Once you've verified the phone number and network status, attempt to resend the message. Use Telnyx's API to resend the message programmatically:
curl -X POST 'https://api.telnyx.com/v2/messages' \
-H 'Content-Type: application/json' \
-d '{
"from": "+1234567890",
"to": "+0987654321",
"text": "Hello, this is a test message!"
}'
