Ask HN: what do you use for mobile connection when abroad? 15 years ago
Data is very difficult and hard to give a universal answer that is meaningful. I use a GSM-based phone so I have options with prepaid sim cards and the like but usually try my best to plan times around known wifi access. This helps too because my Android phone has wifi calling enabled which seamlessly routes my usual U.S.-based mobile number to a voip connection over the local wifi AP.
