I have 1 GB and when I was on my old phone I usually used none of it or just teeny amount as only looked online when at home or at family and so signed into their wifi. I've been doing same except for last Saturday when I was on train journey for 3 hours but I was logged onto Free wifi via Scotrail. Anyway tonight I was out walking the dog and listening to some music via my amazon app, it's music I swapped from old phone and bought a couple of albums recently that were zipped to this phone, and I got a text to say I had used 80%of my data then song and a half later it pinged again to say I had none left. So my question is, does it use up data when listening to my music?
Just looked at phone, I'd put it on aeroplane mode as I was worried I was doing something wrong and somehow running data without knowing it and there are 2 messages on screen saying;
Amazon Music. Your downloads have been paused. Open Amazon Music to resume downloading. No idea what it means as not bought any albums since the 2 last week and they were sent then.
I know it's something I'm doing wrong but no idea what it is, any help will be as much appreciated as other time I was on here greeting. 
Mel, don't apologise please. You've been great help, you've made me turn phone back on! 
Everytime I think I've cracked the iphone thingy something happens to knock it back and my go to is to switch off!
I've put it all back on and turned off the cellular data. Thanks again.
