Hello,

a Metro PCS ad just popped up on my screen where they claim to cover 99% of the people in the U.S.

Is that really true?

I would research their claims...
Also if your getting random popups you should run all your protection scans...it'll only get worse.Metro PCS works with or is part of T-Mobile.
