eSIM and VPN: the two layers most travellers get backwards

They solve different problems, and using one while assuming it does the other job is the common mistake.

Different jobs

An eSIM determines which operator carries your traffic and which country it enters the internet from. A VPN determines who can read that traffic once it moves. Swapping one for the other leaves a gap.

What an eSIM does for privacy

Buying a local SIM usually means showing a passport - in most countries that is now a legal requirement. A travel eSIM bought without identity checks avoids tying a phone number and an IMSI to your name. It also routes through a foreign gateway, which is why travel data often works where the local network filters.

What it does not do is encrypt anything. The operator still sees which servers you contact.

What a VPN does

It encrypts the traffic so the operator sees only a connection to one host, and replaces your address so the sites you open see the exit server instead. What it cannot do is stop the operator knowing which SIM is connected and where.

The order that matters
