Oldham chiefs say fans need to be aware that these are scam messages and they should be deleted.
People who act on them will NOT see the game they've paid for and nor will the club concerned receive the pay-to-view contribution.
Said Oldham chairman Chris Hamilton: "The RFL is very concerned about this and all clubs have been asked to get out this warning to their fans.
"The message is this: Make sure you do match streaming on the official channel, which is Our League."
One of the Our League commentators when Oldham beat Swinton Lions 28-20 at Bower Fold on Good Friday was their former front-row forward and caretaker player-coach John Fieldhouse
Centre Darren Abram, another ex-Oldham player and father of goalkicking full-back Dan, was on duty when Barrow Raiders were at Bower Fold in the first round of the Betfred Challenge Cup.
