упр. 2
SMS was created (Past Simple, Passive) during the late 1980s to work (инфинитив) with a digital technology called (причастие II) GSM (global system for mobile communications), which is (Present Simple) the basis for most modem cell phones.
The Norwegian engineers who were inventing (Past Continuous Active) it wanted (Past Simple Active) a very simple messaging system that worked (Past Simple Active) when users' mobile phones were turned off (Past Simple Passive) or out of signal range.
Most sources agree (Present Simple Active) that the first SMS message was sent (Past Simple Passive) in the UK in 1992. 
As SMS was born (Past Simple Passive) in Europe, it is (Present Simple) not surprising that it took (Past Simple Active) a little longer to make (инфинитив) its way to the United States.
Even today it is (Present Simple) much more popular in Euгоре.
