I just got this about 2 months ago and I've done a lot of reading on it:

This has been a surprisingly good phone. I don't have service on it. I bought it for reading but service is obviously available. It's also available as an unlocked phone but it's easy enough to unlock this one.
It's fast and smooth. Wifi range (important to me) is excellent. The screen is very good and sharp and bright enough for reading in direct sunlight. It has 16 gig and I have a 64 gig micro SD card in it. It's a little larger than I like but not that different than the Iphone 6s. Anyway it might be worth taking a look at.
