> We first show how travel eSIMs often route user data through third-party
networks [---] Second, we analyze the implications of opaque provisioning
workflows, documenting how resellers can access sensitive user data [---]. Third, we validate operational risks such as deletion failures and profile lock-in using a private LTE testbed.
So not about eSIM the technology, but the business landscape inviting opportunistic business people when the bar of entry is lowered. Table 1 is worth a read. The outrage bait about traffic being routed through China shouldn't matter too much to the common person, since we're mostly using TLS. If you're on DoH (DNS over HTTPS), you're even using it for host lookups.
