How to communicate when cell towers are down
This guide goes through what can still get through when cell towers are down (a text, Wi-Fi calling, a 911 call, satellite SOS, a radio), how to set up a family plan, and what to do when nothing gets through.

If towers are crowded, try a text before a call. If towers are truly down, a phone cannot call or text. What still works is Wi-Fi with a working internet link, a satellite feature on some newer phones, a landline, a radio you only listen to, and a plan you made ahead.
This guide goes in order, from the easiest fix to the last resort. It says plainly what does not work.
Can you call or text if cell towers are down?
Not if the towers are truly down. If they are only busy, a text may get through when a call will not. A phone with no tower can still run apps and show saved maps, but it will drain its battery hunting for a signal.
Towers go down for a few reasons. In the FCC's report on Hurricane Helene, 1,079 cell sites in western North Carolina were reported out of service two days after landfall. Of those, 622 were out because of power, 428 because of broken transport links, and 7 because of damage (FCC Helene report). The FCC adds a caution: outage counts do not always match what a customer sees, because nearby sites overlap (FCC Helene report).
The FCC and FEMA give one battery tip for this case. If you see no bars, turning the phone off stops it from draining while it searches (FCC tips).
When the network is busy but not broken, try a text. Ready.gov says texts need less bandwidth, so they travel more reliably when many people are using their phones (Ready.gov, tech). FEMA adds that a text may be saved and sent on its own once there is room (FEMA comm plan). Keep calls short, and wait 10 seconds before you redial (FCC tips). If the towers have no power or no link, neither a text nor a call will go through.
Can you call 911 without service?
If any tower can carry your call, yes. FCC rules say carriers must pass on every 911 call from a phone that can use their network. If no tower in range works, the call cannot go through. Call by voice if you can.
The rule is 47 CFR 9.10(b) (47 CFR 9.10). It makes carriers pass the call along. It does nothing when no tower is working. The FCC also says to make a voice call when you can, because texts to 911 work only in some places and give the call center less information (FCC, Text to 911).
Does Wi-Fi calling work when towers are down?
Yes, if you can reach a working Wi-Fi network with a live internet link, and your carrier supports it. It does not help when the power and the internet are also out. Many outages take down both.
Apple says to use Wi-Fi Calling where you have Wi-Fi but little or no cellular coverage, and that emergency calls might use it (Apple, Wi-Fi Calling). Google says not all carriers support calls over Wi-Fi (Google, Wi-Fi calls). The FCC says you may be able to connect through a secure Wi-Fi network nearby during a power outage (FCC tips). Turn Wi-Fi calling on now, while you still have service.
What works when the phone system is down?
Four things can still work. Satellite texting on some newer phones. A plain landline or a pay phone. A radio you listen to. And in-person plans. None of them is a full replacement for a working network, so use more than one.
| Option | Works with towers down? | The catch |
|---|---|---|
| Text message | Only if the tower works | Fails if towers have no power or link |
| 911 voice call | Only if a tower in range works | Carriers must pass the call, but cannot create a tower |
| Wi-Fi calling | Yes, with working Wi-Fi and internet | Fails if the internet is out |
| Satellite SOS or messaging | Yes, outdoors with a clear sky | Needs a newer iPhone or Pixel |
| Plain landline or pay phone | Can, if the line is not cut | A cordless or internet phone needs power |
| Weather radio or battery radio | Receives only | You cannot send a message |
| Meeting place, paper contacts | Yes | Needs a plan made ahead |
On satellite: Apple says iPhone 14 and later can text emergency services by satellite, outside with a clear view of the sky (Apple, SOS). Google offers a similar feature on newer Pixel phones, and warns that trees and terrain can block the link (Google, satellite SOS). Both say it is for exceptional cases when no other way to reach help exists. Check your own model.
On landlines, FEMA suggests keeping a plain analog phone for times when mobile service is gone, and notes that a pay phone may be less crowded because it does not depend on mobile networks (FEMA comm plan). The FCC warns that internet-based home phone service stops in a power cut without a battery backup (FCC tips).
Will my phone still get emergency alerts if a tower is down?
Probably not. Wireless Emergency Alerts are broadcast from cell towers, so a phone out of range of a working tower will not get them. A battery or hand-crank NOAA Weather Radio can fill the gap, because it receives alerts directly.
The National Weather Service says alerts are broadcast from cell towers to phones in the threat area (NWS, alerts). Ready.gov says they are not slowed by network congestion (Ready.gov, alerts). But congestion is a different problem from a missing tower.
NOAA Weather Radio broadcasts official warnings around the clock. You need a special receiver for it (NWS Weather Radio). A regular radio will not pick it up. The FCC also suggests keeping a battery-powered radio on hand for news during an outage (FCC tips).
How do you make a family communication plan?
Write down who to contact, where to meet, and how to reach one person outside your area. Keep a paper copy. Plans that do not need a network are the ones that still work when towers fail.
- Pick an out-of-town contact. FEMA says a long-distance call can be easier than a call across town, because local lines can jam (FEMA comm plan).
- Choose meeting places: one near home, one in your neighborhood, and one outside your town. Ready.gov asks you to pick a familiar place that is easy to find (Ready.gov, plan).
- Write phone numbers on paper. FEMA notes that a paper copy helps when a battery dies or you lose your device (FEMA comm plan).
- Teach everyone to text. The FCC asks households to make sure contacts know how (FCC tips).
- Practice once. Ask each person where they would go and who they would try to reach.
What if nothing gets through?
Go to your meeting place, share what you know in person, and wait for official word on a radio. Save your battery by turning the phone off or using airplane mode. Then try again later, a few minutes apart.
Spacing out your tries helps everyone. The FCC says repeated quick redials add to network congestion (FCC tips). If you charge a phone in a car, do it in a well-ventilated place. FEMA warns that a car running in a closed garage can cause carbon monoxide poisoning (FEMA comm plan).
When you cannot reach anyone, you may still need answers: how to make water safe, what to do about the cold, how to stay safe with a generator. That is a different problem from sending a message. For it, see the first 72 hours of a power outage guide. If reaching people is your main goal, a satellite messenger is built for that. Our satellite messenger comparison lays out when one is the better buy.
