So pissed 😡 my fiancé is on his parents Verizon plan but pays them for it. I'm staying with mom and she burnt through 15 gigs in 3 days on my iPad! I told her I have to shut off the hotspot. I had my phone paired with hotspot and so did she. I haven't even been home to use it. She also would use the iPad and stream movies all day and night. Well it's $15 a gig and we are over 15 gigs. She didn't apologize or anything. Just said well that doesn't make sense 😡😡😡😡I told her he owes his mom $200 because of it and she just shrugged like it's not her problem
