Locking your iPhone’s SIM card adds yet another layer of security, meaning that even if someone can get into your phone, they still can’t use it to call, text, or access your data plan.
锁定iPhone的SIM卡又增加了一层安全保护，这意味着即使有人可以进入您的手机，他们仍然无法使用它来拨打电话，发短信或访问您的数据计划。
Locking a phone’s SIM card isn’t a new concept. It’s a basic security feature on pretty much all phones, including Android ones. After you enable it, your phone will ask for a special SIM PIN every time you start it up–without it, you won’t be able to make calls, text, and use the device’s data plan. A SIM card lock won’t prevent a thief from swapping out your old card for a new one but that’s okay, at least you know they can’t use your phone or your precious data.
锁定手机的SIM卡并不是一个新概念。 这是几乎所有手机(包括Android手机)上的基本安全功能。 启用它后，手机每次启动时都会要求输入特殊的SIM卡PIN码-如果没有密码，您将无法拨打电话，发短信和使用设备的数据套餐。 SIM卡锁不会阻止小偷用旧卡换成新卡，但这没关系，至少您知道他们不能使用您的手机或您的宝贵数据。
With that in mind, we’re willing to bet that many users aren’t even aware they can lock their iPhone’s SIM card, so today we want to show you how.
考虑到这一点，我们敢打赌很多用户甚至都不知道他们可以锁定iPhone的SIM卡，因此今天我们想向您展示如何。
To lock your iPhone’s SIM card, first open the Settings and tap “Phone”.
要锁定iPhone的SIM卡，请先打开“设置”，然后点按“电话”。
Next, tap “SIM PIN” to turn access this feature.
接下来，点击“ SIM PIN”以启用该功能。
Tap “SIM PIN” to activate it.
点击“ SIM PIN”将其**。
Your SIM will come with a default PIN set by your mobile carrier. This will vary by carrier, but for Sprint and T-Mobile, it should be 1234, for AT&T and Verizon, try 1111. If these codes don’t work, you can either call your carrier or do some Googling. Just make sure you don’t try blindly guessing because if you don’t get it right in three attempts, your SIM card will be disabled.
您的SIM卡将带有您的移动运营商设置的默认PIN码。 具体取决于运营商，但对于Sprint和T-Mobile，应为1234，对于AT＆T和Verizon，应为1111。如果这些代码无效，则可以致电运营商或使用Google谷歌搜索。 只要确保您不要盲目猜测就可以，因为如果三次尝试都做不正确，SIM卡将被禁用。
Once you enter the correct default PIN, your SIM PIN will now be active. Now you still need to change it to your own PIN, since you obviously don’t want it to be the default.
输入正确的默认PIN后，您的SIM PIN现在将处于活动状态。 现在，您仍然需要将其更改为您自己的PIN，因为您显然不希望将其作为默认密码。
Tap “Change PIN”.
点击“更改密码”。
First, you’ll again need to enter the current PIN, which should still be the default (either 1111 or 1234 usually). Then, you need to enter and confirm your new PIN.
首先，您需要再次输入当前PIN，该PIN仍应为默认值(通常为1111或1234)。 然后，您需要输入并确认新的PIN码。
Next, restart your phone. You should get a prompt noting that your SIM is locked. If you simply tap “OK” at this point, your SIM card will be temporarily unavailable until the device prompts you to unlock it again, such as if you try to call or text someone. Tapping “Unlock” will allow you to enter your SIM PIN.
接下来，重新启动手机。 您应该得到一个提示，指出您的SIM卡已锁定。 如果此时仅点按“确定”，您的SIM卡将暂时不可用，直到设备提示您再次将其解锁(例如，如果您尝试致电或发短信给他人)。 点击“解锁”将允许您输入您的SIM卡PIN码。
Just be warned, you will get three tries to enter the correct SIM PIN, after which your SIM will be disabled and you will need to contact your carrier for a new one. Make sure you set up a PIN you can remember, but is difficult to guess.
请注意，您将尝试三次输入正确的SIM卡PIN，然后将其SIM卡禁用，并且需要与运营商联系以获取新的SIM卡PIN码。 确保设置了可以记住但很难猜到的PIN。
Obviously, adding a SIM PIN gives you another layer of security. In addition to the lock you have on your screen, to actually access the device, you need to enter another code to be able to properly use it. For many, this can kind of peace of mind will let you breathe easier especially when a mobile phone is so easy to lose to or can be stolen.
显然，添加SIM卡PIN可以为您提供另一层安全保护。 除了屏幕上的锁之外，要实际访问该设备，还需要输入其他代码才能正确使用该设备。 对于许多人来说，这可以让您高枕无忧，尤其是在手机容易丢失或被盗的情况下。
