What is "expensive" in SMS terms is only relative when roaming charges are taken into account. Let's say an SMS is either free or 5c or less when sent locally and could cost around 20c when sent internationally, it still make sense because it is a one time cost and is relatively cheap, roaming calls can cost about 70c/minute, one can't expect to have the same telecom cost when roaming but in the context, an SMS is practically nothing compared to the savings that can be achieved.
I am all for a simple SMS trigger to get preset things going, once it works well Voxalot can always enhanced it with "specify your destination" type of SMS
