How can I verify if a text message is actually coming from the source identified? I received this spammy text message from the following phone number. 1(833)267-8831 and the message reads "Snapchat: You have friends on Snapchat! Add them: https://snapchat.com/t/39ywfWpgviJ3 To unsubscribe: w.snapchat.com/bXr4ukFF I have this app and have not consented to such communication and do not see a means of managing for them in my preference settings. Snapchat will not give me a definitive answer.

Standard practice is never click on any link in an SMS., ever,
