Yes. Still, what you highlighted in the picture is NOT Email to SMS, it's Events reporting via Email or SMS. :)
Events Reporting via SMS is already in the current firmware, but in a different spot than other routers (you can find it in Services → Events Reporting).
However, Events Reporting via Email is not yet available. But I can see that it is already developed but not yet tested. I asked when it will be available in the standard FW. I'll let you know when I receive a response from RnD.
