When each
format wins.
No travel-data format is universally best. Each was designed for a different traveler shape. Below: which format wins for whom.
eSIM
eSIM is the right format for 90% of solo and couple travelers on 2018+ phones. It is the cheapest format in most countries where airport SIMs carry a captive-market premium. Two-minute setup, no return, no airport counter.
Best for: short trips · solo travelers · multi-country itineraries
Physical SIM
Physical SIM is the right choice when you need a local phone number or have a pre-2018 device. Essential for Grab, Wolt, and country-specific banking apps.
Best for: 30+ day stays · local-number needs · pre-eSIM phones
Pocket WiFi
Pocket WiFi is the right choice for groups of 3+ or content creators running a laptop full-time. Up to 10 devices on one connection.
Best for: families · remote workers · multi-device travel
Carrier Roaming
Roaming is the right choice for 1–2 day stopovers. AT&T and Verizon charge $12/day. T-Mobile Magenta includes data at reduced speeds internationally.
Best for: 1–2 day trips · airport buffer · T-Mo customers
Of travelers we surveyed in 2026 still use a format that costs them money.
Most travelers default to whatever their carrier offers at the airport or out of habit. eSIM adoption is climbing (47% of 2026 trips), but a large majority still leave $30–$70 per trip on the table. This site exists to fix that.
Savings by country.
eSIM saves more in countries where airport SIM markets are captive and pocket WiFi rentals are mature. All prices are May 2026, in USD, for a 5 GB / 7-day plan.

Frequently asked.
Is eSIM cheaper than airport SIM cards in every country?
eSIM is cheaper than airport SIM in most countries we track. Airport SIM counters operate in a captive market with no price competition, which pushes prices $10–$50 higher than online providers. The exceptions are markets with heavily subsidized local SIMs where short stops may favor a local card. Even there, eSIM wins on setup time and queue avoidance.
Does my phone support eSIM?
If your phone is an iPhone XS or newer (2018+), a Pixel 3 or newer, or most flagship Samsung models from 2020 onward, yes. Open Settings, then Cellular, then Add eSIM. If the option exists, you are compatible. US iPhone 14, 15, and 16 are eSIM-only with no physical SIM tray.
Will I keep my home phone number while abroad?
Yes. eSIM runs as a second line alongside your physical SIM in dual-SIM mode. Your home number still receives calls and SMS. Switch your default data line to the eSIM in Settings, and your home line stays available for verification codes and emergencies.
How much data do I need for a 7-day trip?
5 GB covers 7 days of typical tourist use (maps, messaging, occasional video). Heavy users uploading photos to cloud or streaming on transit should pick 10 GB. The most common plan sold is 5 GB / 7 days, priced between $9.50 and $15.00 in May 2026.
Can I tether a laptop from an eSIM?
Yes. Every major travel eSIM provider supports phone hotspot. Throughput matches main-line speed (80–150 Mbps on most modern networks). For 3+ devices full-time, pocket WiFi is still simpler because of battery drain on your phone.
What if my eSIM does not work when I land?
Toggle airplane mode off and on once; 80% of issues fix themselves. If still nothing, set the eSIM as the default data line in Settings. Worst case, contact the provider. Every reputable travel eSIM company refunds unused plans within 24 hours.
