I read on my phone so it uses cellular data but when I need to use my ipad for homework and stuff I just put my phones sim card in it, so if you can still read chapters that are usually only for peopel who pay I highly recommend that you dont use your data or internet when you're on wattpad so it doesn't update it, because when it does you'll have to do the whole coin thing, I never go on wattpad when I use my ipad with internet because I know it'll update. And I'm broke so yeah, hope this helps!
