SMS

SMS = short message service = (phone) text

Texting is commonly used here.  You might say - "It is used in the States too."  True, but here it has business uses I have not seen in the US.   

3 examples - 

SMS are consistently used to send reminders of doctor and dental appointments.  I presume those few people left who are not able to receive texts get these messages another way. 

SMS are used to bid on real estate.  It is quick and easy - but I think "dangerous" to be in a bidding war on property via SMS.  It would be, I presume, very easy to go over one's budget by pressing a few keys. 

SMS are used to confirm ones annual tax statement.  In Sweden, ones tax form is short (costly) and is drawn up by the government.  One receives their filled-out tax form in the mail.  If one agrees with it, one can send an SMS confirmation.
