I get free msg: unable to send message blocking enabled. This only happens on some of my contacts

Hi Cspriggs1,

Thanks for coming to Apple Support Communities for help today.

While we aren't 100% clear on the issue you are having, this article may help you start sending Messages again: If you can't send or receive messages on your iPhone or iPad.

"If you experience issues like conversations in Messages showing up as separate threads or sent messages appearing as green message bubbles instead of blue message bubbles when you set up a new device, update your settings using the following steps:

1. Update your device to the latest version of iOS or iPadOS if needed.
2. In the Settings app, tap Cellular. Make sure that your phone line is turned on. If you use multiple SIMs, make sure that the phone number you want to use is selected and turned on.
3. In the Settings app, tap Messages. Turn iMessage off and then back on.
4. Tap Send & Receive.
5. Tap the phone number that you want to use with Messages."

If that doesn't help, let us know more details. Include, if these are iMessages or SMS that won't send.

Have a fantastic day!

Hey there Cspriggs1,

Since this is occurring with SMS and you have not blocked your contacts, you may want to reach out to your carrier to check if there's issues on their end.

Regards.
