REPORT TAGS probably will not work through a printer template like that. REPORT TAGS are different than Printer Template tags even though they share the same style of syntax.
The only way sending sms works currently is through the printer template… so it will be unlikely. You could probably try some advanced scripting if you had an SMS agent that uses an API that gives you access… but I have zero knowledge if such a thing exists. Additionally you would need to upgrade to v5 to access this scripting support.
