(877) 398-2594
I just received a call from 360-460-1844 7 minutes ago, I have straight talk as well and I also had one seriously harsh virus that attacked my network (AT&T Uverse) cleaned out laptop and desk top would become infected and vs versa...nightmare...straight talk android took on a life of it's own. Purchased a new phone and reformatted all PC's to clean and i just moved, hooked up new and different internet provider last night.
Lets just say, i'm a little paranoid when my cell phone rings and there is dead air on the other end. Why now only get my number??...I feel better now that so many other people have received the same phone call.
