Smartphones are getting bigger by the day, but the 4.5-inch LG Optimus F6 will easily fit in your pocket and your everyday life. Handy features include QSlide, which launches apps in floating windows for multitasking, and QuickMemo for taking notes on the go. You can even use this handset as a remote for your TV. The 4G LTE-enabled F6 sports a sharp 5-MP camera in a lightweight 4.6-ounce body. You get all that for an affordable $199 on MetroPCS, which offers unlimited talk, text and 2.5GB of high-speed data for $50 per month.
