iPhone & IOS Text Failures – Lightwire

Text message “Not Delivered” on iPhone

Fix SMS showing as failed when they’ve actually sent.

This issue affects iPhones and iPads.

If you can’t send text messages, try the steps below. If it still doesn’t work, check our SMS troubleshooting guide.

Sometimes your phone shows a “Not Delivered” error, even though the message actually reaches the other person.

This usually happens when the number saved on your device doesn’t match the number Lightwire has provided.

This only affects SMS (text messages), not iMessages.

You may see a red exclamation mark next to your message, with “Not Delivered” underneath.

Follow these steps in order:

Important: You need to remove your number completely, then add it again. Simply editing it will not fix the issue.

Once done, try sending a text to a non-Apple number to make sure everything is working.

If you’re still having trouble sending texts, get in touch and we’ll help you sort it.
