在 4G 被引入并投入使用之前，每个人都使用 3G 网络。由于速度慢，使用 3G 会令人沮丧。在流式传输或冲浪时，它会面临多次缓冲。后来^(Later)，4G网络出现，取代了3G。但有时，您会面临 4G 网络的一些问题。你可能会问几个问题，比如为什么我的手机说的是LTE而不是 4G？为什么我的4G手机只有3G？这篇关于如何修复 4G 无法正常工作的Android 问题^{(Android issue)}的文章将帮助您解决上述问题。

修复 4G 无法在 Android 上运行的 14 种方法^{(14 Ways to Fix 4G Not Working on Android)}

每个人都需要互联网^(Internet)来交流和学习。在我们周围这个快节奏的世界中，网络连接^{(network connectivity)}速度较慢的移动设备会令人沮丧。第四代网络^{(fourth-generation network)}在很多方面让我们的生活变得轻松。第五代的使用正在增长，但并非在所有地方都可用。尽管网络已经发展到 5G，但我们中的许多人仍然面临 4G 和LTE问题。您可能会遇到问题，而

• 旅行时进行视频通话^{(video call)}或上网。
• 有时，即使您在家工作，您也可能会遇到蜂窝网络问题。 

为了解决这个问题，我们在下面的这篇文章中展示了所有可能的方法。但在使用这些方法之前，请让我们知道您的问题的答案，为什么我的手机在下面的部分中说LTE而不是 4G。^(LTE)

为什么我的手机说的是 LTE 而不是 4G？^{(Why Does My Phone Say LTE Instead of 4G?)}

由于特定区域的网络可用性^{(network availability)}，您的手机可能会显示LTE 。LTE代表长期演进^{(Long Term Evolution)}，实际上比真正的 4G 慢，但比 3G 网络快。由于您所在位置的网络可用，您的手机可能会显示LTE而不是 4G，反之亦然。

初步步骤^{(Preliminary Steps)}

要连接到 4G 网络，您必须执行以下初步步骤。 

• 确保您的 SIM 卡和设备与 4G 兼容^{(Ensure that your SIM cards and device are 4G-compatible)}。如果其中任何一个不兼容 4G，则您无法连接到 4G 网络。
• 检查您是否在正确的插槽中插入了兼容 4G 的 SIM 卡^{(Check that you have inserted 4G compatible SIM in the right slot)}，因为很少有智能手机型号支持特定SIM 卡插槽^{(SIM slot)}中的 4G 。

注意：^(Note:)由于智能手机没有相同的设置^(Settings)选项，并且它们因制造商而异，因此，在更改任何设置之前，请确保设置正确。本文使用的截图来自一加 Nord^{(OnePlus Nord)}。

方法一：重新插入 SIM 卡^{(Method 1: Re-insert SIM Card)}

如果方法 1 和 2 都失败了，那么问题可能是由于插入了SIM 卡^{(SIM card)}造成的。

1. 从“最近^(Recent)”屏幕关闭所有正在运行的应用程序。

2. 使用智能手机随附的SIM 卡顶针，将其插入^{(SIM ejector pin)}SIM 卡托盘^{(SIM card tray)}旁边的针孔中以取出 SIM 卡。

3. 取出SIM 卡托并等待^{(SIM tray and wait)}几秒钟，然后将 SIM 卡托重新插入 SIM 卡^{(reinsert the SIM tray with the SIM card)}。

注意：^(Note:)如果有多个SIM插槽，您应该将SIM 卡插入^{(SIM card)}SIM 托盘^{(SIM tray)}的SIM 1插槽。

4.等待蜂窝网络^{(cellular network)}建立，看看你的设备是否连接到4G网络。

注意：^(Note:)您将在特定SIM 网络的^{(SIM network)}网络栏中^{(network bar)}收到 4G 文本。

方法二：重启设备^{(Method 2: Restart Device)}

如果您在打开蜂窝数据后仍遇到 4G 网络问题，请尝试重新启动您的设备。

1. 按住电源按钮^{(Power button)}几秒钟。

2. 点击重启^(Restart)选项。

方法三：开启移动数据^{(Method 3: Turn On Mobile Data)}

有时，您可能无法打开蜂窝网络，并想知道为什么没有连接 4G。首先^(First)，请按照以下步骤检查移动数据是否已连接。

1. 向下滑动顶部通知栏^{( top notification bar)}以打开设备上的通知面板^{(notification panel)}。

2. 点击移动数据^{(Mobile data)}选项将其打开^(On)。

注意：^(Note:)如果它已经打开，然后点击将其关闭^(Off)，然后再次点击以打开^(On)。

To fix this problem we have shown all the possible methods in this article below. But before going to the methods let us know the answer to your query why does my phone say LTE instead of 4G in the below section.

Why Does My Phone Say LTE Instead of 4G?

Your phone may say LTE due to the network availability of the particular area. LTE stands for Long Term Evolution is actually slower than true 4G but faster than 3G networks. Your phone may say LTE instead of 4G or vice versa due to the availability of the network in the location where you are in.

Preliminary Steps

To get connected to a 4G network, you have to perform the following preliminary steps. 

• Ensure that your SIM cards and device are 4G-compatible. If either of them is not 4G-compatible, then you cannot connect to the 4G network.
• Check that you have inserted 4G compatible SIM in the right slot, as few smartphone models support 4G in a specific SIM slot.

Note: Since smartphones don’t have the same Settings options, and they vary from manufacturer to manufacturer, hence, ensure the correct settings before changing any. The screenshots used in this article are taken from OnePlus Nord.
