title_body: I have a dumb phone LG840G, is there an ebook reader available for it?
upvoted_answer: You should be able to use the browser or UC Browser/Opera Mini to read HTML files from an SD card, that is the best chance to get something usable.
  
  An alternative would be to render the ebook to PNG images and browse the image on the phone, but this takes much more memory.
  
  You can also open plain text files from your SD card using the build in File Browser and read them in the viewer (there might be limitations on the file size).
