A message that doesn’t look legit is a

scam message

Scammers will often use the same company name to make their messages more legit. It might seem crazy, but the online SMS sending services scammers use allow them to make it seem like their messages are authentic and legit.

In an SMS, you can’t disguise the link, meaning scammers can’t use the same links as companies.
