You can store up to 8 eSIMs on your iPhone. These are like 8 physical SIMs. However, you can only have 2 active at the same time.
You can go to 8 different carriers and get 8 eSIMs. Or go to 1 carrier and have them issue 8 eSIMs with 8 different numbers to you. But you will not have 8 phone numbers on 2 eSIMs. To have 8 phone numbers, you need 8 eSIMs with 8 subscriptions (or 8 prepaid plans, whatever suits you).
As stated in my last post, I finally did get US Mobile to set me up by porting the number I wanted onto the same eSIM as my main number. However, the way they did it was by having me sign up on their network using an IMEI that they gave me, not by using either of the 2 that are listed in my phone's settings. I later transferred this number to the IMEI 2 available slot (this would not work at first due to a glitch on their end).
My question is, how does one do this without having to have the carrier give you this IMEI number that you do not see yourself? It was very close to the IMEI number that my IMEI 1 was, but had one or two different digits in it. Where did this come from, and how were they able to make it work?
If I try and add a new number to an existing eSIM, I am given a warning that this will delete the profile that already exists for that IMEI. How would I be able to do what they did on my own if I ever wanted to add another number for some reason?
This entire eSIM thing seems to be an absolute pain in the butt. Gone are the days where one could just grab a SIM, pop it in and be able to switch anytime he/she liked in 5 minutes. Aside from all the headaches I went through yesterday with US Mobile, the activation of the eSIM itself took about an hour when all was said and done. And this was literally after about another 7 hours with their support reps trying to figure out why I couldn't just port in on IMEI 2 to begin with (no exaggeration).
WHAT exactly is Apple thinking??
