When SMS meets Somali culture

We get some interesting SMS feedbacks, some of them start with a 3-line greetings in a typical Somali style: "We send greetings to all Muslim people around the world and hope this msg finds you in good health...May God bless your souls and I wish you sons and milk". I get concerned this beneficiary will be taxed for this long greeting and might get put off from sending further SMSes when he sees the cost.
