Iphone 4: Cellular Data Connectivity Issues

Recently reformatted IPhone back to factory resets (iOS 8.1) and changed phone service providers.

New SIM card works for phone and text, but not data. When I try and connect I get error messages when using Safari, Mail, facebook, etc that there is no cellular network.

Diagnostics I have tried so far...

Tried the apps over wifi, work great.
Confirmed on phone display can see 3g connectivity.
Service provider tech support can see that I am trying to connect (ping)
Together with service provider, diagnosed that the reformat reset also reset the apps that "Use Cellular Data For:" to only Facetime and Passport. I can't seem to get other apps to appear on this list.
When I try and facetime, I cant get it to work over the cellular. Works great over Wifi

Any help appreciated.

iPhone 4S, iOS 8.1

It is very possible that the carrier you use now has different settings for data than the original carrier. Is this an Apple approved carrier you are trying to use? You may need to see about their carrier file, which sets the APN settings for data and messages. If your Use Cellular Data settings have changed, have you checked to see if you have Restrictions turned on in Settings?
