Wifi Compared to celebrity

I'm taking my first princess cruise next year, Wish me luck!

We'll be on the Sky Princess
How is the Wifi compared to celebrity? when we had a celebrity's basic wifi package we were shocked to find all we could use it for was basic web browsing, no downloading or youtube and worse of all no video calling home.

is the medallion net similarly restricted on princess Cruises? Or can I expect to run fairly normal internet on my phone?

I am prepared for it being slower than I get at home.
