android修改 apn

Android gives users a whole lot of customization options, some of which are useful for everyone, while others are just for power users. One of these lower level settings is the Access Point Name—better known as the APN.

Android为用户提供了很多自定义选项，其中一些对每个人都有用，而其他则仅对高级用户有用。 这些较低级别的设置之一是接入点名称-更好地称为APN。

The APN is something most users won’t need to worry about. You pop your SIM card into your phone, maybe reboot it, and it connects to your carrier’s network. You’ll be able to make calls, send messages, browse dank memes, and other important things. But, if you still mess around with custom ROMs, or you’re using an MVNO, you may find that things don’t work automatically.

大多数用户无需担心APN。 您将SIM卡放入手机中，或者重新启动手机，然后它连接到运营商的网络。 您将能够拨打电话，发送消息，浏览潮湿的模因和其他重要内容。 但是，如果您仍然乱用自定义ROM或使用MVNO ，则可能会发现事情不会自动进行。

The APN is all the information your phone uses to connect with your carrier’s network. It lists the address your phone uses to connect to the network, the ports used to handle Multimedia Messaging Service (MMS) messages, the type of data that particular APN uses, and other pieces of information to make sure your phone works correctly.

APN是您的电话用于连接运营商网络的所有信息。 它列出了电话用于连接网络的地址，用于处理多媒体消息服务(MMS)消息的端口，特定APN使用的数据类型以及其他一些信息，以确保电话正常工作。

Some of the settings—-like “APN Type”—could be optional, and your phone will still work without it being 100% correct. Others like “MMSC” and “APN” are much more important, and your phone won’t function if they aren’t entered correctly.

某些设置(例如“ APN类型”)可能是可选的，并且您的手机在100％正确的情况下仍然可以工作。 诸如“ MMSC”和“ APN”之类的其他更为重要，如果未正确输入，您的电话将无法工作。

Thankfully, most phones have the APN for common carriers built-in, so all you need to do is put your SIM card in and let your phone work its magic. This extends to some prepaid carriers as well: I use Mint Mobile, which runs on T-Mobile’s network. When I pop my SIM into my Google Pixel 2 XL or my Samsung Galaxy S8, it just works. The phones already have the APN, and it knows which one to load to connect to a given network.

值得庆幸的是，大多数电话都内置了适用于普通运营商的APN，因此您所需要做的就是放入SIM卡，让电话发挥其神奇的作用。 这也适用于一些预付费运营商：我使用在T-Mobile网络上运行的Mint Mobile。 当我将SIM卡插入Google Pixel 2 XL或三星Galaxy S8时，它就可以正常工作。 这些电话已经具有APN，并且知道要加载哪一个来连接到给定的网络。

On the off chance that you do need to change your APN settings, it’s fairly easy to do. Start by opening the Settings app on your phone. The exact label of the menu will vary, but tap on whichever menu handles your network settings. On the Pixel 2 XL running Android 9.0, this is labeled as “Network & internet.” Then, tap “Mobile network.”

如果确实需要更改APN设置，这很容易做到。 首先打开手机上的“设置”应用。 菜单的确切标签会有所不同，但是请点击处理您的网络设置的菜单。 在运行Android 9.0的Pixel 2 XL上，此标签为“网络与互联网”。 然后，点击“移动网络”。

Tap “Advanced.” Scroll to the bottom of the menu, then select “Access Point Names.”

点击“高级”。 滚动到菜单底部，然后选择“接入点名称”。

Tap the three-dot menu in the upper-right corner, then select “New APN.”

点击右上角的三点菜单，然后选择“新建APN”。

Your APN settings may be included in the package with your prepaid SIM card, or you may need to search for it. Enter the details exactly as they’re listed, then tap the three-dot menu in the upper-right corner, and select “Save.”

您的APN设置可能包含在预付费SIM卡的包装中，或者您可能需要搜索。 输入确切的详细信息，然后点击右上角的三点菜单，然后选择“保存”。

You may also need to make changes to an existing APN. To make these changes, tap on the APN you want to change. Tap on each category, then update the details as necessary. Tap the three-dot menu and select “Save” when you’re finished.

您可能还需要对现有的APN进行更改。 要进行这些更改，请点击您要更改的APN。 点击每个类别，然后根据需要更新详细信息。 点击三点菜单，完成后选择“保存”。

The APNs that come preloaded probably can’t be changed, and if you open them to see the details, you see each item grayed out. Tapping them to change them won’t do anything, so you’ll need to create a whole new APN if you want to change something.

预加载的APN可能无法更改，如果打开它们查看详细信息，则每个项目均显示为灰色。 轻触它们以进行更改将不会执行任何操作，因此，如果要更改某些内容，则需要创建一个全新的APN。

once the APN is set, you won’t have to change it again unless you switch carriers or factory reset your phone. Feel free to make calls, browse the web, and more!

设置了APN后，您无需再次更改它，除非您切换运营商或恢复出厂设置。 随时拨打电话，浏览网络等等！
