Happy birthday SMS should be eye catching in order to attract the reader and lure him/her into wanting to read the entire message
. Adding a bit of humor to the SMS can make the both message and the day more memorable. Another principle when writing birthday messages is that 'less means more'. A brief message that is spot on will be easier for the recipient to read considering that there may be many more messages received. The best time to send a birthday SMS messages is late on the day previous to the birthday date or early on the material day. It is such a special feeling to wake up in the morning and find the phone full of nice wishes. Nevertheless it's still possible to send a belated birthday wish if at all one was not able to do it on the actual birthday.
