There are dozens of factors that can affect your cell service—from your distance to a tower to the weather—but what can you do if, for some reason, your iPhone suddenly isn’t getting a good signal? Let’s find out.

有数十种因素会影响您的电池服务-从您的距离到塔楼到天气-但是，由于某种原因，如果您的iPhone突然收到不好的信号，您该怎么办？ 让我们找出答案。

关闭并再次打开 (Turn It Off and On Again)

“Have you tried turning it off and on again?” It’s clichéd advice for a reason: rebooting stuff fixes a lot of problems. Your iPhone’s cell signal is often one of them.

“你试过把它关掉再打开吗？” 这是一个陈词滥调的建议，原因是：重新启动内容可以解决很多问题。 iPhone的手机信号通常是其中之一。

So much goes on behind the scene in any operating system that troubleshooting them all individually is next to impossible. Instead, by turning your iPhone off and then back on, you get it to start everything afresh. If, for example, it’s stuck on the 3G network rather than the 4G one, turning it off and on will force it to reconnect to the network. Similarly, if it’s a background process that’s causing the issue, that process will be terminated and restarted by a reboot.

在任何操作系统中，都有如此多的事情发生，以至于不可能对它们全部进行单独故障排除。 相反，通过关闭然后重新打开iPhone，可以重新启动一切。 例如，如果它卡在3G网络而不是4G网络上，则将其关闭然后再打开将强制其重新连接到网络。 同样，如果是导致该问题的后台进程，则该进程将终止并通过重新启动来重新启动。

检查网络中断 (Check for Network Outages)

If rebooting your iPhone doesn’t do anything, there’s a chance your carrier is experiencing an outage. If this is the case, there’s not a whole lot you can do until they fix whatever the problem on their end is.

如果重新启动iPhone无法执行任何操作，则可能是运营商出现了故障。 如果是这样的话，在他们解决最终的问题之前，您将无能为力。

Most carriers are pretty quick to post about outages on their websites and social media channels. Some also have an outage hotline you can call for more information or to report an outage. Your best bet for finding this info in a hurry is just to Google “[Your Carrier Name] outages”.

大多数运营商很快就会在其网站和社交媒体渠道上发布有关中断的信息。 有些还设有中断热线，您可以致电以获取更多信息或报告中断。 急于查找此信息的最佳选择就是Google“ [您的运营商名称]停运”。

There’s also DownDetector.com which crowdsources outage reports; if there’s a huge spike or reported outages on your network in your area, the fault is probably with your carrier.

还有DownDetector.com ，它可以将停机报告众包； 如果您所在区域的网络上出现高峰或报告中断，则故障可能出在您的运营商身上。

重置网络设置 (Reset Your Network Settings)

Resetting your network settings deletes all your saved network information like Wi-Fi passwords and carrier settings. If the issue is being caused by a bug or incorrect value somewhere deep in iOS’s network handling software, this should fix it.

重置网络设置会删除所有已保存的网络信息，例如Wi-Fi密码和运营商设置。 如果问题是由iOS网络处理软件中某个地方的错误或错误值引起的，则应将其修复。

Go to Settings > General > Reset Network Settings, enter your password, and confirm that you want to reset your network settings.

转到设置>常规>重置网络设置，输入密码，然后确认您要重置网络设置。

Your iPhone will restart and once it’s back on, your network settings will be totally reset. Bear in mind, you’ll need to reconnect to any Wi-Fi networks or Bluetooth connections you use.

您的iPhone将重新启动，一旦重新打开，您的网络设置将完全重置。 请记住，您需要重新连接到您使用的任何Wi-Fi网络或蓝牙连接。

如果家里信号不好怎么办 (What to Do If You Get Bad Signal at Home)

If your bad signal isn’t just a one-time problem, but is ongoing, then your options are a little different.

如果您的不良信号不仅是一次性的问题，而且还在持续，那么您的选择就会有些不同。

Wi-Fi calling is an absolute game changer if you have poor network coverage at home. If your cell service is bad, your phone will instead make calls and send texts over your Wi-Fi network. It’s often a lot easier to get fast broadband than a good cell signal inside a well built building. In the US, all the major carriers offer it. Check out our guide on how to enable wi-fi calling on your iPhone.

如果您在家中的网络覆盖范围很差，Wi-Fi通话绝对可以改变游戏规则。 如果您的手机服务不好，您的手机将通过Wi-Fi网络拨打电话并发送短信。 获得快速宽带通常比建造良好的建筑物内的良好小区信号要容易得多。 在美国，所有主要运营商都提供它。 查看有关如何在iPhone上启用Wi-Fi通话的指南。

You’ll need an iPhone 6 or later (or an iPhone 6s or later if you use AT&T, for some reason) to use Wi-Fi calling.

您需要使用iPhone 6或更高版本(如果出于某些原因使用AT＆T，则需要iPhone 6s或更高版本)才能使用Wi-Fi通话。

Some networks offer cell boosters that can take one bar of signal and make it a bit better. There are also femtocells that create a small cell base station that connects to the network over your broadband. They both work, but neither option is as good as Wi-Fi calling.

某些网络提供的细胞增强器可以吸收一个信号条并使其变得更好。 还有一些毫微微小区创建了一个小型基站，该基站通过宽带连接到网络。 它们都可以工作，但是没有一个选项比Wi-Fi通话更好。

如果细胞信号到处都不好怎么办 (What to Do If Your Cell Signal Is Bad Everwhere)

If your cell service is bad everywhere, then you need to change something: your network, your SIM card, or your phone.

如果您的手机服务到处都不好，那么您需要进行一些更改：您的网络，SIM卡或电话。

Different networks have different coverage. If you’ve moved from a city where your carrier was reliable to one where they don’t have great coverage, the best option is to switch networks to whoever has strong coverage as soon as your contract is up.

不同的网络具有不同的覆盖范围。 如果您从运营商可靠的城市转移到覆盖范围不广的城市，最好的选择是在合同签订后立即将网络切换到覆盖范围广的人。

If you’re the only one getting bad signal on a network and nothing else has fixed it, then the next thing to do is ask your network for a new SIM card (as long as your iPhone uses one). SIMs get updated from time to time and can fail like any piece of tech, so replacing it might fix things.

如果您是网络上唯一收到不良信号的人，而没有任何其他方法可以解决此问题，那么下一步就是向您的网络询问新的SIM卡(只要您的iPhone使用一个)。 SIM卡会不时更新，并且可能会像任何一项技术一样发生故障，因此更换SIM卡可能会解决问题。

If it’s not the SIM, then the only thing it can be is a hardware fault in your iPhone. If it’s still under warranty, contact Apple or your network and ask about getting it repaired or replaced. If it’s not under warranty, then your only real choice if you want a better signal is to get a new phone.

如果不是SIM卡，那么唯一可能的原因就是iPhone中的硬件故障。 如果仍在保修期内，请与Apple或您的网络联系，并询问有关对其进行修理或更换的信息。 如果不在保修范围内，那么您想要获得更好的信号的唯一选择就是购买新手机。
