SMS History SMS was created during the late 1980s to work with a digital technology called GSM (global system for mobile communications), which is the basis for most modem cell phones.

Most sources agree that the first SMS message was sent in the UK in 1992. As SMS was born in Europe, it's not surprising that it took a little longer to make its way to the United States. Even today it is much more popular in Euгоре. A July 2005 study found that 37 percent of U.8. mobile phone owners had sent or received at least one text message in the previous month.
