I was afraid of this, when I bought my 15PM. Traveled to Chile, and what would have been a quick transaction at the Entel store ended in disappointment. Apparently you need a Chilean ID to purchase an eSIM. Fortunately, I brought a pixel 3 I can hotspot, and takes a nano sim, but it’s something of a hassle. My only regret so far.
Can’t you just use airalo to get ESIM? It’s more expensive but no papers required
