Vodafone in Germany was happy to give me an eSIM for a prepaid plan, not even a store visit required (but it did require taking a photo of my ID and a identity verification video call where someone checks your video against the ID).
I guess with AI-based video manipulation, a store visit may be required in the future...
Or not, considering how store employees are treated and paid. It's probably much cheaper to bribe some low-level clerk than build & deploy a convincing AI spoofing solution.
