i switched back from the P7 Pro my 14 PM today through Verizon's website. They call it switching or activating a new phone on my existing number. It was esim to esim all they needed was the IMEI number for the 14 PM
I made sure I had internet access from my home wifi then deleted the esim on the P7 Pro and turned it off. Then turned on the 14 PM and added a new esim and it automatically activated through Verizon. Whole process took 10 minutes.
From what i've heard from the Marques dude on his YT channel is that it's much easier/quicker going from an Android phone to an iPhone and according to him, Apple made it not as easy switching from the iPhone to Android.
Here's where I see a few eSIM problems.
1) Are carriers going to charge each time you switch?
2) Are they going to limit free eSIM swaps? Mint Mobile (my carrier) limits 2 free then charges $3 per swap in a 12 month period.
3) Are carriers going to streamline the process and make it easier to switch even without an internet connection? Apple supposedly lets you switch by downloading your eSIM via satellites.
For me this is an annoyance because it takes me less than 10 secs to pullout the Sim card from one phone and insert it into another and I am up and running.
