I have the 13 Pro Max, and I usually by a local sim when traveling. This is going to be a factor to me, and I don't always have the option to plan ahead. I was in Thailand recently a fellow traveler invited me to join him to see Ankor Wat so was spontaneously in Cambodia. a Physical sim was $4 for unlimited high-speed data, I have no idea if esim was an option then or if not when it will be. I would hate to be restricted to that across the whole world. When I upgrade to the 15, I will have to see what my options are and maybe get a European or Asian Iphone.
