💬 SMS messages alongside email in an automation or campaign?

With most things, there is a work around. I was wondering how y'all in the hive mind that are sending SMS messages have been able to do it within automations (Telegram could possibly work too but not preferred).

My use case:

I deal with complex personal issues so people often avoid going back into the courses. However with a little nudge they do. While email is good, people are relying more and more on their phones and notifications.

I know how to handle all the tagging and customization with email, but wanted to add in SMS for weekly reminders. Everyone will be enrolling at different times so it won't be a broadcast and needs to be done in the automation.

Appreciate all feedback and suggestions
