3Gstore Antenna Jack Locator: Sprint 3G/4G U600


The U600 has multiple antenna ports, including one for a 4G antenna and one for a 3G antenna. The 3G port is the top port on the side closest to the "3G" LED indicator; the 4G port is below that on the opposite side. IMPORTANT: the ports require DIFFERENT ADAPTERS! (*boosting 4G signal requires a 4G-compatible antenna)
