I helped a friend activate eSIM with Verizon Wireless so I thought I'd make a post to help others out and possibly clear up any confusion. His example was combining 2 numbers into 1 phone. This is also the process if you want to change from a physical SIM to an eSIM to free up your physical SIM slot to be used with an international carrier, etc.
Verizon Wireless began supporting eSIM activations around iOS 12.1.1 rollout early December
To change from physical SIM to eSIM simply contact Verizon Wireless via call or chat
Let the representative know you want to perform a change from physical to eSIM
Provide rep with Digital SIM IMEI via Settings > General > About
Note: must use Digital SIM IMEI (exactly how it is labeled in the iPhone)
At this point Verizon Wireless' system will generate an electronic ICCID (SIM number)
Verizon Wireless will then request an email address to send a QR code to
You MUST scan the QR code to finalize the change. e.g. use your iPhone to scan the code via your email on a computer or tablet
To scan the QR code, on your iPhone go to Settings > Cellular > Add Cellular Plan
Once the QR code is scanned, the change will complete
If your not a Verizon Wireless user and want to activate a line of service on eSIM you can do so by downloading My Verizon app (so I'm told)
Follow the instructions there to process your own activation
One important caveat is this: if you plan to travel internationally and get a SIM for the local area you're traveling to, activate your eSIM BEFORE you go. You can not activate any Verizon service outside the USA.
