Run a campaign for me with a text message component to get phone numbers and emails for marketing and orders

I’m looking to run an ad for my pie business.
I want to replicate this ad. ESPECIALLY the text message aspect. I want to offer a free pie and drink with orders so I can get orders and people to subscribe to my text message marketing.

Here’s a link to the ad – https://www.facebook.com/101891244895063/posts/492937029123814/?d=n

I was scrolling on Facebook and saw this campaign for a good business offering a free sandwich with an order of equal or greater value.

Once I clicked the ad it took me to messenger and then asked for my phone number. It then sent me a text message to subscribe to their text alerts (see attached pictures)

Here’s the link to the ad so you can see it for yourself:

I was looking into text messaging systems and this looks like it could work for me, but I’m open to suggestions:
