NanKate if you are worried about using too much of your friend’s data, you could find some films etc on Netflix and download them onto iPad using own WiFi. Then watch them at her place. One thing I’ve found when watching Netflix on iPad is that volume using built in speaker is quite low. It’s probably ok for 1 person who could use headphones, but if 2 of you want to watch, it might be worthwhile bringing small Bluetooth speaker.
