Is this a scam?

Yes it's a scam.

willing to bet scam. unless you make payments for a T-mobile profile..whatever in the heck that is..

any payments would go through Mint and not TMO.

I believe it's a scam. I received the same thing, but i was scared to open it lol.... Hopefully you, and me as well get a answer to this. 

Definitely a scam. Tis the season.

I'm a mintmobile customer ! They told me to ask here so here it goes.

I got a txt msg ,it reads  ,From shipping91@usps82service.onmicrosoft.com
