Privacy differences between eSIM vs. physical SIM

Traveling privately and securely is difficult with an eSIM. A lot of travel eSIM providers have been discovered to route your connection through Chinese-owned servers regardless of your eSIM location. There are not a lot of good options if you are planning to visit countries (i.e. Southeast Asia) that do not readily sell eSIMS. Be prepared to head to their version of a carrier store instead of acquiring a cheap sim card at the airport or tourist center.
