> So is there no network access at all other than these apps? I don't see that clarified on the page.

No, the 'regular' access goes out of your normal data cap, and of course they have every reason to lower that cap as much as possible so you're more or less forced to buy these packages.

This is just the first step, they are trying to get consumers used to paying for special data packages like this. The next step is to keep lowering regular data caps, etc.

scroll down the page. those are addons to the basic internet package.

That's what it seemed like to me, but wasn't sure. So basically non-established players are actually free, but established players require additional money? i.e. the opposite of what the parent comment was saying?

It's giving you additional per-app data usage. So if your kid uses 8GB a month on Snapchat, you can pay extra to increase the data cap just for those social apps. Otherwise it would count against your regular data usage.
