eSIM vs Physical SIM
Which is better for travel? A complete side-by-side comparison covering convenience, cost, availability, and compatibility.
eSIM wins for travel — with one caveat
eSIM is faster, more convenient, and increasingly universal. The caveat: your phone must support it. iPhone XR and later, and most Android flagships from 2020 onwards, are eSIM-capable. For country-by-country eSIM support details, see our eSIM coverage guide.

When physical SIM still wins
eSIM isn't perfect for every situation. There are three scenarios where a physical SIM still makes more sense. Before travelling, check the eSIM data plans guide to understand costs and plan types.
If your phone is an iPhone 8 or earlier, or an older Android, it won't support eSIM. A physical SIM is your only option.
Some budget phones are locked to a carrier and cannot use third-party eSIMs until unlocked. Check with your carrier first.
A small number of countries have restricted eSIM infrastructure. Cuba, parts of sub-Saharan Africa, and some markets still rely heavily on physical SIMs.
