VIsited WYS earlier this month, had zero reception the entire time. Boostmobile is my provider that piggy backs on Sprint. Everyone in our party had service(Verizon,ATT etc). Had good reception when we traveled to Jackson, WY.Was this review helpful to you?
We stayed in West Yellowstone, and as long as we were within (approx.) a ten mile radius, we had a signal. Once we ventured away from "civilization", the signal quickly degrades. We only checked signal strength in areas where we figured that we could receive a signal, but in general, don't plan on being able to use the phone inside the park.Was this review helpful to you?
