How to Call for Help When There's No Network (High-Rise Emergencies)
无网络时怎么求救：高层火灾等紧急情况通讯方案
The most important signal is the one that reaches help when everything else is down. Students living alone overseas — this one's worth saving.
最重要的信号，是在一切都失效时还能触达救援的那个。独自在海外的留学生——这篇值得收藏。
When the network fails, know these当网络失效时，先知道这些
In an extreme emergency — a high-rise fire, an earthquake, a major outage — mobile towers can lose power and your phone can lose all signal. Knowing how to call for help without a network can genuinely matter. As a network business we spend our days on connectivity, but the most important signal is the one that reaches help when everything else is down. This is a safety explainer, not network troubleshooting.
在极端灾难下——高层火灾、地震、大面积断网——基站可能断电，手机可能完全失去信号。掌握「无网络求救」的方法，真的可能救命。作为做网络的，我们每天都在讲连接，但最重要的信号，是在一切都失效时还能触达救援的那个。本文是安全科普，不是网络排障。
If mobile networks are down移动网络不可用时
- Try an emergency call (000 in Australia; 112 works on many phones and can route through any available network). Emergency calls can sometimes connect even when normal calls can't.
- Send an SMS for help — a text can get through on weaker signal than a voice call, so it's worth trying when calls fail.
- Use your phone's offline SOS — on iPhone, press the side button five times; many Android phones have an SOS that sounds an alarm and flashes the light even with no signal. These can make sound and light to attract attention and help rescuers locate you.
- 尝试紧急电话（澳洲 000；很多手机上 112 也可，能通过任意可用网络接通）。紧急电话有时在普通电话打不通时也能接通。
- 发短信求救——短信在比语音更弱的信号下也可能发出去，电话失败时值得一试。
- 用手机离线 SOS——iPhone 连按侧键五次；很多安卓有 SOS，即使没信号也能发警报声、闪光灯。它们能发声、发光吸引注意，帮救援人员定位你。
Visual & sound signals可视与声音信号
When you can't communicate outward at all, focus on being found:
- At a window: wave a bright cloth or use a torch to signal; movement and light draw attention.
- Sound: a whistle carries far, needs no power, and is less tiring than shouting; knocking on pipes or walls in a rhythm also travels.
- Torch over phone flashlight: a dedicated torch lasts far longer and is brighter for signalling.
当你完全无法对外通讯时，重点是让别人找到你：
- 在窗口：挥舞亮色布料或用手电打信号；动作和光能吸引注意。
- 声音：口哨传得远、不用电、也比喊叫省力；有节奏地敲击管道或墙壁也能传出去。
- 手电优于手机手电：专用手电续航久得多、打信号也更亮。
Building emergency systems楼内应急系统
Most high-rise buildings have systems that don't depend on your phone: fire alarm break-glass points, emergency intercoms/warden phones, and fire stairs with signage. Learn where these are when you move in. In a fire, if you can't safely exit, the standard advice is to stay in a closed, low-smoke room, block gaps under doors to keep smoke out, and keep signalling your presence so firefighters can find you.
大多数高层都有不依赖你手机的系统：火警手动报警按钮（break-glass）、应急对讲/消防电话、以及带指示牌的消防楼梯。入住时先弄清它们在哪。火灾中如果无法安全撤离，标准建议是：留在封闭、烟少的房间，堵住门缝挡烟，并持续制造「存在信号」，让消防员找到你。
What to prepare (nothing risky)日常准备（都不危险）
- A fully-charged high-capacity power bank at home.
- A torch (saves phone battery vs the flashlight).
- A simple whistle (no power, audible far).
- Set emergency contacts and Medical ID in your phone; know your floor number and the exit locations.
- Keep a phone charged and know your building's assembly point.
- 家里放一个满电的大容量充电宝。
- 一个手电筒（比手机手电省电）。
- 一个简单的口哨（无电力、长距离可听）。
- 在手机里设置紧急联系人和医疗急救卡；记住你的楼层号和出口位置。
- 手机保持有电，知道楼里的集合点在哪。
Priority order when there's no network无网络时的求救优先顺序
- Emergency call (000 / 112) — system-level, may connect when normal calls don't.
- SMS for help — can succeed on very weak signal.
- Offline SOS (iPhone side button ×5 / Android SOS).
- Window light/wave signals; whistle or knocking.
- Building alarm points / intercoms.
- Shelter in a low-smoke room and keep signalling your presence until rescued.
- 紧急电话（000 / 112）——系统级，普通电话打不通时也可能接通。
- 发短信求救——在极弱信号下也可能成功。
- 离线 SOS（iPhone 侧键连按 5 次 / 安卓 SOS）。
- 窗口灯光/挥手信号；口哨或敲击。
- 楼内报警按钮 / 对讲。
- 在烟少的房间避险，持续制造「存在信号」直到获救。
Frequently asked questions常见问题
What's the emergency number in Australia?澳洲的紧急电话是多少？+
000 is the primary emergency number in Australia (for police, fire and ambulance). 112 also works from mobile phones and can route through any available network, which is useful when your own carrier has no signal.
000 是澳洲主要的紧急电话（警察、消防、救护）。手机上 112 也可用，能通过任意可用网络接通，在你自己运营商没信号时很有用。
How do I call for help if my phone has no signal?手机没信号怎么求救？+
Try an emergency call (000/112) — these can connect via any network. If calls fail, send an SMS (works on weaker signal), use your phone's offline SOS (iPhone side button five times), and make light/sound signals (torch, whistle) to be located.
先试紧急电话（000/112）——可通过任意网络接通。电话不行就发短信（弱信号也可能成功）、用手机离线 SOS（iPhone 连按侧键 5 次），并用手电、口哨等光/声信号让人找到你。
