1. I went with the CNET Cheapskate advice and got a zero dollar a month Freedompop SIM. It was under 10 bucks and I am in year 3 without a phone bill.
2. I can't help you find where you put your files but to play them I use VLC Player for Android on my Android.
I've decided to use my S4 as a media device for offline use, but I have encountered 2 issues:
1. The timezone is incorrect and keeps changing back to the incorrect timezone resulting in incorrect time, but I am not sure how to correct this as it has no SIM card.
2. I have a Seagate media device that I use wirelessly, but in downloading any media to the phone, the files (video, music, pics) cannot be found and does not show up anywhere.
I'm not sure what to do about these issues. My phone is an A5.
