Can we send a survey via text message to someone every day, week, or month?

Yes! To do that you'll want to use Storylines for the automated messaging functions. 

You can set the frequency: multiple times daily, daily, week, monthly or any variation, just choose which "Day #" to send the survey (or text message containing a survey link from a third party) and then enroll study subjects into the Storyline. Mosio will do the rest.

If you are using Mosio's text message surveys, then you're able to add those from a dropdown inside of Storylines. 

If you're using a third party for surveys and want to send those links, you can add those when creating your Storyline messages.

To use Mosio Storylines, you'll want a Basic or Plus Plan.
