If you want a sleak, brand-new in its original sealed box sim-card-based cellphone with a good camera, a removeable battery, SD card slot, bright 5" screen, easy to set up, easy to use, and extremely fast charging, and which costs under $230, consider the Samsung Galaxy S5. Actually, it's kind of a no-brainer. It's no longer available from the carriers, but it is available from Amazon and other places such as BH Photo, which actually bought branded phones from the carriers. Just be sure, wherever you get it, it has a 30-day no questions-asked return policy, in case you don't like it for any reason. Avoid eBay at all cost.
