I'm not sure if there's some special calling feature to reach a previously associated provider, but when I've been in that situation I just borrowed my roommate's phone.
Yes, it is possible. You use whatever the provider's method is to download an eSIM to that device. Usually it's logging into their app or calling their support to register the IMEI or whatever.
In the store if you're getting the phone from a store, or somewhere with wifi (home, a friend's, a cafe) if you've gotten it some other way.
If you don't have any of those, you probably live way out in the jungle, and I'd be surprised if you had service even if you got the eSIM. But in the edge case that you somehow got home delivery postal service in the jungle, you'd probably be able to survive just fine without it until your next trip into town.
In the extreme edge case that you are in the jungle, get service, and your need is critical, I would have an activated backup phone tested periodically and ready to go.
Depends on the phone. The newest ones let you use multiple ones simultaneously, one for calls/texts and one for data, for example. Slightly older ones only let you use one at a time, but they let you activate and deactivate multiple downloaded eSIMs.
Your provider won't issue a new eSIM?
No, they issue it virtually. Then you download it via their app or via regular cell network provisioning.
That doesn't have anything to do with what we're talking about.
The newest few generations of phones support multiple SIMs.
You call support and have them issue a new one.
