Hi. My name is Matthew. I visited nTelos at the NRV Mall in Bluefield, West Virginia and bought a SIM card for my phone for $10 to enable LTE service. The max speeds I got was 27 Mbps up and 14 down. The current locations for LTE are Bluefield, WV; Beckley, WV; and Waynesboro, NC. The man there put a "Carrier Update" on my phone after he inserted the new nTelos SIM card into my phone. It took about 25 minutes to complete the process. I own a iPhone 5s and it works great only when and where I'm able to use it.
