Which should you choose?

One important distinction: direct SMS notifications from the monitoring service are different from an integration that sends alerts through another provider. SMS availability, credits, and pricing can vary by plan.

Are you looking for an SMS integration to add to your existing uptime monitor, or are you willing to switch to a monitoring service that includes SMS alerts? That determines which options are most relevant.
