旅行 eSIM 与当地 SIM 卡

Most travel plans are data-only and include no in-country number, which is enough for maps, chat apps, app-based calls and ride bookings, since all of those run over the internet. If you specifically need a local number to receive verification texts from a local service, check that plan's details before buying, or ask us to check the specific plan you are looking at.

Often cheaper per gigabyte, and more so on longer stays. But a fair comparison has to include the SIM itself, the time queueing and registering, travel to a point of sale if you do not buy at the airport, and the offline window from landing. Counted fully, the gap on a short trip is usually narrower than expected. We do not quote figures because they differ by country and by season.

On most multi-SIM-capable phones, yes: keep your existing line on for calls and texts, and set the eSIM as the line used for data. The exact settings and menu names differ by manufacturer and OS version, so look under your phone's mobile network or SIM settings. What to watch is what your home line charges while abroad — check that with your own operator before travelling.

If you installed an eSIM before travelling, it is not a problem — you activate it yourself on landing. If you did not, the options are airport public WiFi where it exists, or waiting until morning, which can make booking a ride or reaching your accommodation that first night difficult. This is the main reason people prepare an eSIM for day one even when they fully intend to buy a local SIM.

Registration rules differ by country and can change. Many countries require identification, which for travellers usually means a passport, and some also ask for your accommodation address. We do not list country-by-country detail because it changes; check the official information for your destination before you travel, and keep your passport accessible if you plan to buy.

Yes, and it is a common approach for long stays. Let the eSIM cover the opening stretch when you have no time to find a shop, then arrange the local SIM once accommodation is sorted. By then you know roughly what you use per day, so you can pick the local package more accurately than guessing on day one.
