Was in Harrisonburg yesterday for something, and really enjoyed Shentel's LTE service there. The handoff from nTelos-land to Shentel was seamless - barely a hiccup in my music streaming on I-81. However, going home was a completely different story!! Upon leaving Shentel's area around Weyers Cave, I dropped signal altogether. I tried toggling Mobile Data off/on several times, airplane mode several times, etc. No dice. Had the No CDMA service indication. Finally rebooted my phone around Waynesboro, and it finally got back on nTelos.
Not sure if this reflects on the network or my M9, but it was quite disappointing. *sigh*
