SMS stands for “short message service” and typically refers to a communication method that sends texts between phones. As such, a love SMS is a love message sent between phones via text messaging. For example, a love SMS posted on Lovemessage.org states, “As I lie awake in my bed. All sorts of thoughts run through my head, Like why do I love you as much as I do. Then I realize its because you are you."
Another example of a love SMS is, “A special smile a special face. A special someone I cant replace. I luv u, I always will. U've filled a space no one can fill!” A love SMS may also say: “People say you only fall in love once, but when I hear your voice, I fall in love all over again.”
People often shorten words in SMS texts to get around the 160 character limit. This limit is where the word “short” in SMS comes from, according to HowStuffWorks.com. The character limit is even shorter for people who use other alphabets. For example, those who use the Chinese alphabet have a 60-character limit.
The actual data that an SMS text contains is more than just letters. The other information includes the length of the message, the time that the user sends it, the user's phone number, and the phone number to which the user sends.
