So I have Xfinity and your supposed to be able to do this via web. I was riding my dual sport deep in the woods and lost my phone. Tried my damn way to activate an s21+ I had in a drawer and it kept kicking it back. I go to store and they cannot activate it as it’s “but supported by their network”. They try to sell me a new phone. I’m frustrated and on like day 3 no phone so I said fuck it I’ll buy the cheapest Motorola on the shelf, but inder one condition. I refused to buy the phone or continue my contract unless they would give me a physical sim (they tried pushing the esim HARD). I got home, took the sim out of my Motorola, popped it into my “unsupported phone” and JT worked fucking fine. Esims are just another complication and way to get tech illiterate into the store. As long as I can I will never let go of my physical sim ever again.
