Does NOT allow you to put an address in the phone directory. Does NOT have or allow any games. Does NOT allow any apps to be installed. Does NOT have GPS. Does NOT allow you to use Google or Bing maps on the browser because it does NOT allow Java Script. This lack is a problem because it prevents many sites from showing information. Bcause it does NOT allow Java script, many prices, e.g. at Amazon, do NOT show. I do not recommend this phone any longer. And, does NOT block phone numbers from anyone outside of Straighttalk customers. Does NOT stabilize pictures when using 1.3 megapixel camera. Does NOT allow editing of pictures, such as rotation.
Pro: Does allow up to 16gb miniSD card for music, pics and ringtones. Keyboard works well even with my large fingers. The battery life is a week or more for me who does not use the phone much, and about 4 days if I use the MP3 player, which I do daily for an hour or so. Use earbuds instead of the weak phone speakers. The screen is a good size for a cell phone. It is visible in sunlight by adjusting brightness.
