From reading another thread in these forums and also looking elsewhere on the internet, there appears to be no way to activate a new Verizon eSIM if a Verizon customer is outside of the US. This is rather concerning, as stuff happens all the time and if someone needed to buy a new phone while abroad, they'd be out of luck trying to get their Verizon number activated on the replacement phone?
I guess if you have a physical SIM card, that could be placed into a replacement phone, but the latest generations of iPhone are eSIM only as an example.
