常見問題

A SIM card that is downloaded instead of posted. Your phone stores the profile internally, so there is no plastic card to collect, swap or lose — and nothing to return when your trip ends.

2019 年之後上市的手機大多支援 eSIM（iPhone XS 以後的機型、Google Pixel 3 以後的機型、近幾年的 Samsung Galaxy 旗艦等）。撥打 *#06#，若顯示 EID 號碼就代表支援。此外手機還必須是無鎖機（未鎖定電信業者）。

No. The eSIM is added alongside the SIM you already use, and you choose which line carries data. Nothing is removed, so there is no card to keep safe and nothing to put back when you get home.

Yes. Orders placed on this site are delivered by email within minutes, day or night, and installing takes about two more. Amazon orders need to be redeemed first, which usually takes about five minutes once Amazon has confirmed the payment.

建議出發前在家用 Wi-Fi 裝好，但先把 eSIM 門號關著。到了當地再打開——有效期是從第一次連上網路開始算，不是從安裝當下算。

打開兌換頁面，填寫 Amazon 訂單編號（在「我的訂單」可以查到）和要收 QR code 的信箱，大約 5 分鐘就會收到。

That message is expected before you travel: the profile cannot reach its network until you are in the destination. Look at Settings › Cellular (Android: SIM manager) instead — if the plan is listed there, installation worked and it will activate on arrival.

Also normal when you install ahead of a trip. The profile is waiting for a network it cannot see yet, and it clears once you land. You do not need to reinstall — reinstalling is what usually causes real problems.

Either the phone is still locked to a carrier, or this QR code has already been installed once. Check your list of lines first. If the phone is locked, only the carrier that sold it can unlock it — we cannot.

Any label is fine — it is just a name on your screen. Call it SIMLESS or Travel so you can find it later. When asked which line to use for calls, messages and data, keep your usual line for now and switch data to SIMLESS after you land.

No. The plan starts on the first connection in your destination, so switching the line on at home does not consume anything — your phone simply cannot find that network yet.

From the first connection abroad. Most plans count a day as a full 24 hours from that moment; some count calendar days that end at 23:59 in the plan’s own time zone. The email that delivered your eSIM states which rule applies to the plan you bought.

可以。通話和簡訊繼續走您原本的 SIM（或原有的 eSIM），行動數據交給 SIMLESS 的 eSIM。記得把原門號的數據漫遊關掉，以免產生費用。

Yes — one profile covers the whole region, and your phone switches operator as you cross borders. If it does not pick a network up after an hour in a new country, open Network Selection, turn Automatic off and choose an operator by hand.

You get the same 4G/5G networks local customers use, at local speeds, wherever 5G is available on that plan. We do not throttle. Speeds still vary with coverage, crowding and your phone, exactly as they would on a local SIM.

Restart the phone, then toggle airplane mode on and off. If that does not settle it, select the operator manually under Network Selection. Do not delete the eSIM — contact us from Wi-Fi and we will work it out with you.

可以。所有方案都支援個人熱點，不另外收費。

就是停止上網，不會產生任何超額費用。需要的話，幾分鐘就能再買一份新方案裝上。

Once the plan has expired and you are home. Deleting is permanent — the same QR code cannot be installed again — so keep it while you are still travelling, even if something is not working.
