Internet on my Verizon iPhone stopped working, why?

About a month ago I ran out of my monthly data, which is normally not a big deal because it resets on the 25th of every month, but for some reason this entire month of July it has not reset. Whenever I leave a place with Wi-Fi I'm not able to access the Internet on my iPhone. Why is this? What should I do? I have Verizon.

Try reinstating and restart with mobile, try resetting the internet setting

  • Why did the sound on my iPhone 4 stopped working? Okay so I was in the middle of watching a YouTube video on my phone. And then all the sudden at 1:30 AM my sound shut off. I was so pissed! So I looked at my side switch on my phone, it was off and I looked at the disturb button in settings it was off! An when I get a message no ring! There's no sound AT ALL. I tried turning it on and off it didn't work and I also tried double clicking the home button and minusing all of my apps didn't work!
