Don’t worry, a lot of people got it.
If you hadn’t googled it already:
Yes. It literally got pushed out to the entire world. I’ve seen from A10 to S10+, all carriers, from South Korea to Germany.
As of writing, no official response but user reports say support is saying it was a glitch/accident.
Interesting! I was worried this morning and wondering if there was some kind of hack that happened but it kinda slipped my mind as I was off to the gym and running on 5 hours of sleep xD Thanks for the info!
It was a glitch/accident until everyone starts sifting through their additional taxes/fees in the bills and realize there’s more monthly charges appended because of this service that is no longer something you can opt out of… 
Is this glitch exclusive to samsong? cause I use xiaomi and got one two days ago for no reason
Official Response:
This was last night (about 4am UTC). I am not aware of other instances for other phone makes.
