I'm about to go over my data on my iPhone 4S?

Is there a way I can stop my phone from using my data? My data won't reset til July 6th so ill need to keep it off for 2 more weeks.
If there's a way… Will using say safari or another app when on Wi-Fi not use any data at all?

Go to your settings and turn off your cellular data.

Okay, so if you use Wi-Fi than you're good, you won't be using data if your Wi-Fi is on. However, if you aren't using your Wi-Fi and if you're on something like:
- Safari
- YouTube
- Facebook
- Instagram
Okay, you get the idea
So if you're using an app that uses data when you're not on Wi-Fi, you'll be using your data plan
If you go to settings-->General-->Cellular
And turn cellular off, you won't be allowed to use an app that uses data, you can still snap photos, play on some apps, write notes and stuff like that! Just not anything that uses data so if you turn that on you'll be good, only turn it on if you're not using Wi-Fi because than you don't need it.
Summary:
- Use Wi-Fi
- Turn off cellular to stop using apps that use data
- Turn cellular back on when you're using Wi-Fi
Hope this helps!
