We use Verizon for cell-service & internet. We have 75GB of streaming data on each of our phones. We kept an extra solely to use for streaming & as a hotspot for work (3 total). We also utilize a Verizon MiFi device, but the speed is throttled after 15GB, which you can go through quickly. Because we were concerned about getting consistent cell reception across the US we also purchased a cell booster. We will write a review on that at some point.
*Most parks offer free WiFi, which we will utilize for watching Netflix, Hulu, etc. but it isn’t consistent enough to rely on for work.
