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.
I have multiple phones I rotate between using. Some don’t have eSIMs and when I want to move service to a different phone I’d need to set up the eSIM on the different phone or go and buy a new pSIM.
Too much of a hassle for me. I won’t buy anymore iPhones till Apple returns the pSIM slot.
