Thanks for the reply. Understand.
FYI, there is not a technical reason why an eSIM canāt be remotely provisioned over any data channel. (i.e. via another carrierās mobile data or WiFi)
Itās quite literally nothing but files which are securely downloaded, validated, and installed into the phoneās eSIM. [essentially a āsecure enclaveā for the carrier(s) inside your device]
In your case itās apparently the case that the carrier chooses NOT to do so as a matter of administrative and/or procedural policy. (As there indeed ARE significant security risks which must be mitigated)
(although that policy may be driven by the carrierās own lack of āback officeā hardware / software / procedures / training to remotely provision via means other than their own mobile RF network)
