Text congestion mars testing of tsunami warning system

Link: IOL: SMS glitch mars testing of tsunami warning.

Of more concern to test organisers was news later that plans to alert emergency coordinators to tsunami threats failed to work in Thailand when busy cell phone networks took hours to deliver key messages.

“The problem we faced was with communications. We have no idea whether our messages sent to local operations chiefs by fax and SMS arrived on time or not, and by midday some of them said they did not receive the SMS,” Pakdivat Vajirapanlop from the National Disaster Warning Centre told AFP.

I wonder if they have the ability to flag tsunami warning SMS messages so they get the highest priority on the network?
