My iPhone 5c won't send iMessages, snapchats, email from the Mail app, and it won't load YouTube. Other internet apps like Pandora and Instagram work fine though. Any suggestions on how I can fix this?
A couple days ago I first noticed the problem when snapchats would appear on my lock screen but when I opened the app I kept getting the error message that the app was not able to refresh my story. Then the next day I was no longer able to send iMessages, they wouldn't go through and would only reach the second party when I sent them as text messages. Also, YouTube won't load and Mail won't send or receive email. I've already tried restarting my phone but there was no change. At first I thought my network connection was the problem but Instagram, Safari, Vine and Pandora all work perfectly. Any suggestions?
iPhone 5c, iOS 7.1
