Of course, we do everything we can to prevent critical errors on our production environment. But yea, sometimes, they happen. And most of the times, they happen on very inconvenient moments, or on moments they get noticed too late, like during the weekend.
For these last cases, I'd like to be able to subscribe to SMS alerts with critical errors. Just like the alert emails, but as an SMS. So I'll be able to reply faster once an error occurs.
