I'm blessed in living in a country with perfect 4G coverage and data plans that make it enjoyable. We have generally three sim car types: normal phone sim (roaming, voice and some limited data ~5-10GB but you can tether), tablet sims (around 20GB data only with roaming) and stationary internet sims (unlimited data, no roaming, no voice). I have two of the latter and it boosted my happiness working from coffee places. I bought a good portable 4G router with 12 hours of battery and that worked out so well for me that I actually cancelled my wired home internet.
