Stopping annoying Instant SMS messages from 270-00

I’ve been receiving annoying instant SMS messages from 270-00 on a weekly basis. The messages were usually trivia like “Jupiter is 11 times the diameters of earth and is the largest planet in the solar system,” or “In 1607 English settlers arrived on the coast of Virginia, they called in Jamestown. Many of the people did not survive the first winder.” Very “interesting” trivia!

Based on my google search, I replied a “Stop” message and several minutes later an another SMS came back stating “U have been unsubscribed from 2Minute IQ Mobile Quiz Club subs. U will no longer receive any messages or charges. 8002357105.” Hopefully, this really stopped annoying weekly trivia SMS message.
