Suspected Malware - JUMP! - from a source claiming to represent T-Mobile.

Hello and welcome, @adonsa​! Thanks for joining our Community and posting about this message. The text you're referring to is an enrollment welcome SMS from Assurant, the vendor who operates the Premium Device Protection program that T-Mobile offers (in other words, insurance or JUMP! insurance). It sounds like this wasn't a service that you'd elected to establish on your line. If that's the case, we definitely want to have you Contact Us if you haven't done so already so that we can review your account and get this feature removed! Please don't worry about downloading the document -- it should be safe, although in your case, it certainly doesn't sound like it's necessary. Thank you, and I'm sorry for any confusion here!
