While dual SIM technology has been around for several years now, the new iPhone X series (XS, XS Max, and XR) marks the first time it’s been available in an iPhone. But what does that mean?

儘管雙SIM卡技術已經存在了幾年，但新的iPhone X系列(XS，XS Max和XR)標誌著它首次在iPhone中使用。 但是，這是什麼意思？

“雙SIM卡”是什麼意思？ (What Does “Dual SIM” Mean?)

If you’re a lifelong iPhone user, this might be the first time you’ve encountered the term “dual SIM,” so a bit of explanation is in order. For starters, it’s exactly what it sounds like:you have two SIM slots in your phone instead of just one. This way, you can have two phone numbers—even from two different carriers—all on one phone. The phone will seamlessly switch between the two SIM cards for calls, texts, and data.

如果您是終身使用iPhone的使用者，那麼這可能是您第一次遇到“雙SIM卡”一詞，因此有必要進行一些說明。 對於初學者來說，它的確是這樣：您的手機中有兩個SIM卡插槽，而不僅僅是一個。 這樣，您可以在一個電話上擁有兩個電話號碼，甚至來自兩個不同的運營商。 手機將在兩個SIM卡之間無縫切換，以進行通話，傳送簡訊和傳送資料。

Historically, this meant dual SIM phones have needed two physical SIM card slots. In the case of the new iPhone X series, however, it’s using a single nanoSIM—the same type of slot iPhones have used since the iPhone 4—along with

從歷史上看，這意味著雙SIM卡電話需要兩個物理SIM卡插槽。 但是，對於新的iPhone X系列，它使用的是單個nanoSIM(與自iPhone 4開始使用的相同型別的iPhone插槽)以及新的eSIM插槽。

eSIM, or “embedded SIM,” is a new type of non-removable SIM card that carriers can program. This means switching carriers doesn’t require a SIM swap; you won’t even have to walk into a brick and mortar store since carriers can program the eSIM remotely. You’ll even be able to program it yourself with an app.

eSIM或“嵌入式SIM”是運營商可以程式設計的新型不可移動SIM卡。 這意味著交換運營商不需要SIM交換。 您甚至不必走進實體店，因為運營商可以遠端對eSIM進行程式設計。 您甚至可以使用應用程式對其進行程式設計。

Dual SIM is great for anyone with two phones numbers—like a personal number and business number, for example. It’s also great for international travel, as you can keep your home SIM in one slot, then add your international SIM to the second.

雙SIM卡非常適合擁有兩個電話號碼(例如個人號碼和公司號碼)的任何人。 這對於國際旅行也非常有用，因為您可以將家用SIM卡放在一個插槽中，然後將國際SIM卡新增到第二個插槽中。

Note: The Chinese iPhone X series phones will have two SIM slots instead of using eSIM.

注意：中文iPhone X系列手機將具有兩個SIM卡插槽，而不是使用eSIM卡。

太酷了，那麼誰支援eSIM？ (Cool, So Who Supports eSIM?)

In its current state, eSIM is still relatively new tech—especially in phones. The Apple Watch has been using eSIM for a bit, and some smarthome tech also supports it. For phones, however, it’s not as common yet.

在當前狀態下，eSIM仍是相對較新的技術，尤其是在手機中。 Apple Watch一直在使用eSIM，並且一些智慧家居技術也支援它。 但是，對於手機來說，它還不那麼普遍。

At the time of this writing, AT&T, Verizon, and T-Mobile all support eSIM, so you’ll be able to switch between them quickly and easily. Then you can drop your work or international SIM card into the available slot on your iPhone.

在撰寫本文時，AT＆T，Verizon和T-Mobile都支援eSIM，因此您可以在它們之間快速輕鬆地進行切換。 然後，您可以將工作或國際SIM卡放入iPhone上的可用插槽。

If you’re on another carrier, well, you’re out of luck for the time being. Thatdoes notmean you won’t be able to use a new iPhone on your carrier, of course—it just means that the eSIM won’t be active and you’ll be limited to a single SIM slot.

如果您在另一家承運人上，那麼，您暫時不走運。 那不當然，這意味著您將無法在運營商上使用新的iPhone，這僅意味著eSIM卡將無法使用，您將只能使用一個SIM卡插槽。

In other words, nothing changes for you. Easy peasy.

換句話說，什麼都不會改變。 十分簡單。
