Hi, I'm a website designer, and one of my recent projects has asked about text-based messaging for some aspects of the website.

I am aware it can be done, but I've never done it myself. I'm wondering if anyone knows where to start from / research.

- how is it done
- How much does it cost etc (I assume it's not free)
- how do we set it up?

Ps, the topic of the website is based in NZ, but it's hosted (currently) on a USA server. 

And I am aware of the multiple telecommunication services in NZ. 

What if we set this up via Spark? but the end-user is with another company?

some things I can think of using it for:
- confirmation code when someone registers themselves / their mobile phone number.
- Text to the manager when some specific action is needed / for their attention etc.
