Is a physical SIM cheaper than an eSIM abroad?

Sometimes, in specific countries. Local prepaid SIMs bought at an airport kiosk in India, Vietnam, or Thailand often beat travel-eSIM per-GB rates. Outside those well-stocked markets, travel eSIMs typically beat the price of a foreign physical SIM bought at retail by a wide margin — and undercut home-carrier roaming by 5–20×.

Can I get a local phone number with an eSIM?

Generally no, on travel eSIMs from the providers tracked on eSIMBench. They're data-only. A few specialist services issue real phone numbers on eSIMs (Airalo's Hi product, JMP.chat, some MNO eSIM offerings), but the mainstream travel-eSIM market is data-only by design — the home SIM stays active for SMS and calls.

If my phone supports eSIM, is there any reason to use a physical SIM?

Two real ones. First, an unsupported destination — if the only carrier with workable coverage doesn't offer eSIM activation, a physical SIM is the only path. Second, a temporary phone — borrowed devices, an old burner, or a second phone for the trip won't have your travel eSIM profile and can't easily get it without re-purchase.

eSIM vs physical SIM for travel: when each one wins

Physical SIMs still win in three real situations: countries with no eSIM-friendly local carriers, phones older than the 2018 iPhone XS (or pre-2020 Android flagships), and trips where the buyer needs a local phone number for SMS verification. Everywhere else, a travel eSIM is cheaper to activate, faster to start working, and easier to manage from the airport.

The cost difference is real but not infinite. A 10-day Italy trip on Airalo’s regional Europe plan currently runs at a small fraction of UK or US carrier roaming charges, and roughly matches what a local Italian prepaid SIM would cost at a Vodafone shop. The eSIM wins on convenience (no shop visit, no SIM-tray swap) and ties or loses on raw cost in well-stocked SIM markets. In countries with kiosk-heavy SIM economies — India, Vietnam, Thailand, Indonesia — a local physical SIM at the airport often beats the travel-eSIM rate per GB. In countries where SIM cards require ID registration and the buyer doesn’t want to hand over their passport for a 5-day trip, eSIMs sidestep the friction entirely.

The phone-number question is the one most travelers don’t think about until day two. Travel eSIMs on every provider in the eSIMBench tracked set are data-only. They do not get a phone number. Two-factor codes still arrive on the home number, because the home SIM is still active alongside the eSIM. Voice calls and SMS continue to route through the home carrier’s network — and incur the home carrier’s roaming charges for any inbound voice/SMS that does come through. For most travelers this is fine: WhatsApp and iMessage over the eSIM data covers actual conversation; the home number is just a 2FA receiver.

For trips where a local phone number matters — booking restaurants that only accept local SMS, ride-hail apps that demand a local OTP, opening a domestic bank account — a physical SIM is still the more reliable path. Some eSIM products advertise local numbers; their fine print typically reveals they’re virtual numbers that may not pass SMS-based verification on all services.

The phone-compatibility question has a clearer answer: every iPhone since the XS (2018) supports eSIM, and US-market iPhone 14 and newer are eSIM-only. On Android, most flagship phones since the 2020 Pixel 4 / Galaxy S20 support eSIM, but coverage is patchy on mid-range and older devices. Xiaomi, Oppo, and OnePlus support eSIM unevenly across regions and models. If the phone isn’t on the provider’s supported-device list, the eSIM question is moot.

The practical conclusion most travelers should reach: try the eSIM path first for any trip. The activation is free to attempt — buying a 1 GB starter plan and installing it costs roughly the price of a coffee. If activation succeeds, the SIM kiosk visit is avoided. If it fails (compatibility issue, network problem at the destination), the physical SIM is still available as a fallback at the airport. The Best for short-trip travelers ranking is a good starting shortlist; the Best for first-time users ranking re-weights the dimensions for activation-and-support friction.
