I hit some US Cellular roaming in North Carolina. A bit ironically I used to have the old unlimited where roaming was uncapped, but I'd get about 80-100kbps due to the roaming agreement with US Cellular being 1x only. Now I can get a nice strong LTE signal but at 128kbps. Oh well, the pings are much better at least . I did test call my voicemail while I was on it, it went through on VoLTE and sounded fine.
