eSIMs & Connectivity
An eSIM lets a compatible phone add a local or regional data plan digitally, without swapping a physical SIM card — useful for avoiding roaming charges or hunting for a local SIM shop on arrival. The providers below mostly compete on the same few things: how many countries and regions they cover, whether a plan is a fixed data allowance or includes voice/SMS, how easy the activation process is, and whether unused data can roll over or top up mid-trip.
An eSIM plan isn't the only way to get connected — a physical local SIM is often cheaper for a longer stay in one country, and some travellers just rely on their home carrier's roaming pass. An eSIM tends to win on convenience: it can be set up before you land and doesn't require a compatible phone to be physically unlocked in the way a swapped SIM sometimes does.
Check device compatibility (not every phone supports eSIM, and some carrier-locked phones block it even when the hardware does) before buying a plan.
The right choice here mostly comes down to which countries you're visiting, how much data you'll realistically use, and whether your phone actually supports eSIM. Provider pages below go into what each one is actually built for, and where two options genuinely overlap, a comparison page puts them side by side.

Not necessarily — a physical local SIM is often cheaper for a longer stay in one country, and some travellers just rely on their home carrier's roaming pass. An eSIM plan competes mainly on convenience, not always on price.
