Can't download apps like Snapchat and Instagram on my iPhone?

My software is up to date and I can download other apps like Save My Snaps or photo edits for Instagram but I can't download the actual Snapchat or Instagram.

First download the apps using your apple id and iTunes on the computer to download them.

Then using the same apple id as you used on iTunes download the apps on your iPhone.

  • Why can't I download snapchat onto my iphone? I had snapchat on my device before however I deleted it I went back to the app store to download it again yet no matter how many times I try or how long I wait it doesn't give me the option to re-download it The download with cloud doesn't pop up and neither does the "free" Is there any way I can get it back on my device?
  • When I get a notification for Snapchat or Instagram the noises won't go off? They pop up but they never make a sound, I've looked on notifications in settings and in sounds, my phone isn't on silent (btw it is iPhone 4S) if that helps, please help it is bothering me, I tend to miss loads of notifications, it is also on full ringer, please help!
  • If I turn off cellular data on my iPhone, can I still use apps like SnapChat and Instagram? I have to share a 2GB plan with two other people, and I think that if I just blocked off cellular data it would prevent me from going over (obviously). But just personally, can I still use social applications and whatnot since the Wi-Fi will still work?
