Staying connected abroad is easier than ever. Here's how to weigh eSIM against traditional roaming.
How eSIM works
A data-only eSIM downloads to a compatible phone and activates on arrival — no physical SIM swap.
When roaming still makes sense
Short single-country trips or plans with included roaming bundles can be convenient, though often pricier.
Compare before you commit
Check coverage, data allowances and validity across providers, then activate with the partner you choose.
