I've been traveling the US full-time (RV) with my family (wife & 3 teens) for 5 years. I pair-program daily (over SSH/TMUX) and only require audio streaming for chat, generally don't need video or screen-sharing. We have 3 lines of Verizon "Beyond Unlimited" (not sure if they offer this anymore). I believe that is "unlimited" up to 75GB from the phone itself, and 25 or 30GB hotspot, per line. The kids burn through their data fairly quickly so we look for parks/resorts that have some sort of WIFI option, whether public or paid, to supplement their needs. For my personal and work usage, I'm able to get by without reaching my cap each month on the Verizon plan. I also purchased a cellular booster (weboost) which has made a huge difference in some rural areas. Staying connected to the interwebs is what bank-rolls this operation so it has been the single biggest pain-point for travel, but doing research on locations has help mitigate some of that. https://www.campgroundreviews.com has been a good resource. Hope that helps. Happy/safe travels.
