My cellular data is not working on my iphone?

I have my cellular date enabled. I can only call and receive calls. But I can't use apps like what's app or viber.

For the record you don't need data to send/receive calls, hence why they work fine now.

As far as your data check your data settings, particularly the APN settings for it.

  • Why isn't my cellular data working? I have an unlocked and jailbroken iPhone 4S. I know where the cellular data is at but when I turn it on it doesn't work, & it even says 3G on the corner but I don't know why it's not working! Can someone help?
  • Why does my iphone use data over night when cellular data is turned off? Every night I turn off cellular data and leave the iPhone on and one day I wake up and check my data manager and see i have already used 25 MB please help!
  • When you have Wi-Fi and cellular data on at the same time, does it use cellular data? If I keep my cellular data on and also have my iPhone connected to Wi-Fi, will it use any of my cellular data?
  • My cellular data isn't working? I have an iPhone 6 and recently my data hasn't been working. Say I want to use Spotify without Wi-Fi, so I go into the data settings and turn on Spotify. Then I open the app and it says offline. I go back to settings and it's turned off so I tried turning it back on again then switching back to Spotify and it's turned off again! This happens with all my apps but Snapchat. I have no idea how to fix this so if someone knows please let me know it's super annoying!
