For many of us who want to be prepared, we spend a lot of time building food storage and making sure we have sufficient water stored. Often, though, a gap in our preparedness is having a reliable communications system with family members to use during an emergency. So much is dependent on technology and what we have put in place ahead of time.
Using phone apps to talk to people is a viable option, and the Zello app is a nifty tool that can be a strong component, although just one layer, of a good emergency communications. Here’s why.
What is Zello?
Zello (Friends and Family version) is a free app that converts your smartphone into a walkie-talkie so you can talk to anyone anywhere in the world, as long as you have an operating cellular network. You don’t need a lot of bandwidth, but you definitely need internet access through wi-fi or a cellular data network. (Read this post for ideas about how to prepare for an internet outage.)
Remember walkie talkies when you were a kid? One person pushes the button and talks while the other person listens and you alternate back and forth. The Zello app makes your smartphone act exactly like a “push-to-talk” walkie talkie–only it’s way cooler because your range is pretty much anywhere in the world.
How Zello Works During a Crisis
A major benefit of Zello is that contacting someone through the app is faster than calling during an emergency. Zello only uses a fraction of the bandwidth of a phone call so it works even when calls are getting hung up with busy lines. You’ll have to test it to see what I mean, but you don’t wait for a phone to ring because Zello allows your voice to come directly through the phone. Honestly, it’s a little startling to hear a voice suddenly coming through your phone the first time you use it, but you get used to it. So Zello is as fast as a text, but you get the immediacy of a phone call.
Zello was first brought to the public’s attention by the “Cajun Navy” during flood rescue operations and is now widely used in natural disaster rescue operations. During the weeks of Hurricane Harvey, I used Zello to help coordinate water and food distribution among the hundreds of families in my town whose homes had been flooded. It was simple to learn and use.
It’s been used to stay in touch through tornado warnings, tracking wildfires, and during power outages.
Like a walkie talkie radio system, Zello gives multiple people the ability to be on a channel at the same time. Participants can check in and hear critical information simultaneously, potentially saving precious minutes. This is one of the best ways to have an entire family and/or friend group on the same channel, perhaps with agreed-upon check-in times should an emergency happen.
Another useful feature of Zello is that all communications are recorded and stored on the app. This allows you to access the messages later or replay them to confirm specific details. I imagine this is handy if stress levels are high or multiple people are on the line.
I think this ability to communicate as a group over vast distances is reason enough for families to have Zello as part of their communication plans. You can establish everyone’s status or confirm a rendezvous point with one “call.”
Pros and Cons
Pros
- Fast and efficient
- You can talk to–not just text–your people even when phone calls get hung up
- You can talk to several or all of your people at once with a Group or Channel
- Everything you say is recorded and stored and can be played back
- If you are not available, the message is recorded so you can hear it later
- You do not need Wi-Fi or a lot of bandwidth for Zello to work, just a cellular data network
Cons
- Cell networks must be operating
- Your people must have downloaded and learned how to use the app before an emergency
Our Experience with Zello in an Emergency
In an oddly timely turn of fate, my family had a chance to test out Zello when our power went down for two days during a massive wind storm. I can report that Zello worked as advertised! We were able to contact our children who live locally and one who lives across the country from us. Our son commented it was slightly disturbing to hear my voice unexpectedly coming out of his phone the first time. Definitely set up and test the app before using it for emergency communications.
The Verdict
Even though Zello requires an internet connection, it’s one of the best tools for staying in touch. The app functions like a walkie-talkie, enabling reliable group communication across long distances. Even in areas with weak cellular signals, Zello allows families to quickly connect, confirm everyone’s status, or establish a meeting point with a single “call.” In situations where there is an ongoing threat, such as civil unrest or a full-blown riot where there is the possibility of being separated, it allows real-time coordination. While Zello shouldn’t be your sole communication method, it offers a valuable layer within a comprehensive plan for emergency communications.
Tips for Using Zello for Emergency Communication
- Proactive Communication: When adding contacts to Zello, avoid sending a generic invite. Text them first to let them know you’re adding them to your family’s emergency communication plan on Zello. This will help avoid confusion and ensure they don’t dismiss the Zello invite as spam.
- Test Zello Regularly: Don’t wait for an emergency! Test your Zello app with family members to ensure everyone can communicate effectively. Use it at public events, such as music festival or concerts, or at public locations like a shopping mall.
- Explore “Channels” for Wider Communication (Optional): If your community utilizes Zello channels for disaster response, explore joining them for broader situational awareness.
- Use Offline Messaging: Zello messages are recorded even if unavailable. Use this feature to leave messages for family members to hear later.
How Families Can Use Zello
My husband and I are now discovering different uses for Zello outside of emergency communications. We use it to talk from different areas on our property or if one of us is under the house. It’s faster than calling, especially when we need help with something quickly. We also plan on testing Zello at some concerts and a music festival this summer. It’s faster and easier than texting and calls don’t always go through at crowded events.
A few other uses:
- Checking in during a storm
- Neighborhood communication
- Road trip coordination
- Kids walking home from school
- Large family events
- Evacuation coordination
Zello and similar communications apps are simple to learn, simple to use, and free.
How to Set Up Zello On Your Phone
Downloading the app is free and easy for both iphone and Android users. Download zello for android phones here. Download Zello for iOS here and desktop version at this link.
It’s slightly confusing to add contacts, but after a few minutes of fiddling around, my husband and I figured it out.
Once you add a phone number into the contacts list, the app will send a message to that contact asking them if they want to download Zello. It was an easy process from there to add our whole family. Hint: we texted people first so they wouldn’t think it was a spam and delete the text.
Groups and Channels
Groups are private conversations between contacts.Channels are a platform for communication with larger groups, including strangers. You can have up to 6000 people on a Channel.
Status Options
You can choose to keep the Zello app on “available,” like we do, without draining your battery. However, the app also has a feature where you can put your setting on “Busy” to silence messages coming in so you aren’t startled by a voice randomly coming out of your phone during a meeting. You are then notified that you have a message.
Once additional status mode, is “solo.” If you have multiple channels, this allows you to focus on just one specific channel. Messages received in other channels can be retrieved from History at a later time. If you are using Zello for non-emergency communication, then in a crisis, you may wish to silence those in order to focus on the one you’ve set up just for emergencies.
Four Alternatives to Zello
Several other helpful communications apps work just as well as Zello.
- Voxer — Very popular app, easy to use. Also records messages for later replay.
- Discord — Activate the PTT (Push To Talk) mode. Free and you can set up a server and use push-to-talk in voice channels, which effectively mimics a walkie-talkie for groups.
- TeamSpeak — Usually used by gamers but can be used by anyone as a PTT way to chat.
- HeyTell — Another app. Free and basic.
- Two Way: Walkie Talkie App — Another simple, free app. Uses WiFi or data.
IMPORTANT: Learn to use the app of your choice and then have a second one as a backup. Make sure everyone in the family not only has the app downloaded but they know how and when to use it.
Does Zello Work Without Internet?
Zello works extremely well as long as your phone has internet access, either cellular data or Wi-Fi. Without an internet connection, Zello usually won’t function, which is why it’s important to have backup communication options like radios or satellite communication, for anything from a brief internet outage to an EMP event.
What If There’s No Internet For Your Communications App?
Starlink. The Starlink technology all but guarantees internet connection anywhere in the world, even in extreme conditions like war or a devastating natural disaster. As of this writing, almost 10,000 satellites supporting Starlink are in orbit, making it a unique, robust option for staying connected.
My brother and sister-in-law are currently on a year-long sailing trip, and their only form of internet connection is Starlink. They say it has been completely reliable. We chat via Messenger, share Instagram reels, and talk via smartphones on a regular basis.
Having either a Mini Starlink or the regular-sized version makes complete sense if you want to have a solid backup for internet connection, both for communication and information. This can be a part of your preps for an internet outage.
The Starlink set-up is simple:
- Download the Starlink app on your phone.
- The app uses your phone camera to show you if you have a clear enough view of the sky (no obstructions from trees or rooflines).
- Point it towards the sky.
- Plug it in to any electric outlet, power bank for quiet and safe indoor power, or generator.
- Connect it to the WiFi router it comes with.
This backup allows you to continue to use Zello or any other communications app, even if the power and/or internet is down.
FAQ
It offers a faster, push-to-talk connection, works in congested networks, and lets you create groups for quick family communication.
According to Zello’s support documentation: “Your conversation histories are stored on the individual device where the messages were received and cannot be accessed by Zello staff. Messages are only stored on our servers when you send a message to a user who is offline. In this case, messages are stored for a maximum of two weeks until retrieved by the recipient.”
Unlike walkie-talkies, Zello has no distance limit. With an internet connection (cellular data or wifi) and the Zello app, you can talk to anyone anywhere on the globe.
Per Zello’s support documentation: “All voice messages sent privately to your contacts are end-to-end encrypted on Zello Friends & Family…[However] channels are open to the public. This means that voice messages sent within channels are not encrypted.”
Yes, the Friends & Family version is free to use.

Final Thoughts
Zello and similar phone apps offer a fast and reliable way for families to communicate during emergencies, functioning as a walkie-talkie app on your smartphones. While they require internet access via Wi-FI or a cellular data network, they can be a valuable addition to your Family Emergency Communication Plan alongside other methods. Remember, they’re just one tool, but with the ability to connect quickly and record messages, they’re a valuable option for emergency communications.




There proably be no wifi or any connections in this emergency. The app will not work. Or am I reading this wrong.
That’s correct. You need wifi, but the majority of emergencies will still have wifi. One example that happened to me was the huge flooding during Hurricane Harvey. I was part of a network that used Zello to direct emergency responders to people stranded in their homes. Even a power outage doesn’t necessarily mean no wifi.
Don’t wear earbuds, use your smartphone or landline, or handle plugged in devices or appliances during thunder (electrical) storms as lightning seeks wires.
Your cell and WiFi connectivity depends on the type of towers or rooftop sites in your area. Use what is still working early in a power outage, because it will eventually affect most of the 4G, 5G and WiFi transmitters if the outage is widespread and electricity is not restored quickly. Due to a number of factors, the typical coverage radius of a cell tower is only 1 to 3 miles and in dense urban environments, a cell phone tower usually reaches 0.25 miles to 1 mile before handing off a user’s connection to another nearby cell site. That’s because not only is there higher usage taking up capacity, the higher the frequency of the signal (4G, 5G) the faster the signal dissipates and the call or internet connection would drop. WiFi lasts longer because it is a lower frequency. This explains why it can get through to a tower that still has power when a regular cell call cannot. But it is slowed by traffic using up capacity as well, so use it early before other users try it.
Only 1/5th of the transmitters are large ones on a site where there is a backup generator and fuel to run it 24 to 72 hours. If you are close enough (within 3 miles) to one of those, even though it is carrying the traffic of the emergency responders, there should be enough bandwidth for you to get on the cell or WiFi frequency long enough for some back-and-forth with your closest family or group.
Little antennas on public light poles will go out when the lights go out, and the mobile or WiFi service can’t do anything about it. They only transmit 50 to 2,000 feet. When the power to the light pole goes out, so does the cell antenna.
Most tower owners from whom the networks rent space for their transmitters and antennas move generators to where the outage is. American Tower, for example, has 9,000 generators to take care of emergency power to 50,000 towers. Some are stationary but most are haulable generators the size of a truck. They are accompanied by a fuel truck with diesel or propane or gas, and technicians to set it up and refuel it, to a major hub tower experiencing an outage if a generator isn’t already stationed there. However, 3/4ths of both the cell and WiFi transmitters are on leased space on the roofs of private buildings, or public light poles. The generators can’t reach the rooftop installations of multi-story buildings from the ground with long enough temporary cables, can’t plug into their regular fuse box, and can’t be put on the roofs due to weight, noise, fueling and servicing. This infrastructure risk when the public utility electricity is interrupted was always a known vulnerability to the cell phone industry and government. The FCC mandated that all towers have backup power since 2007 and Katrina. But 17 years later they don’t. And they won’t for the foreseeable future. The logistics of local and state noise abatement and structural laws, fire hazzards for the storage of generator fuel, lease agreements with the private landlords, space available (usually none at the base of the tower), proximity to residences for fumes and emissions, etc. mean that they can’t.
If you’re near enough to a tower with a generator, typically one near a city center, hospital, government offices, corporate headquarters district, or airport of a large metropolis, you’re in luck. If not, don’t expect the WiFi network to last any longer than the cell network. They are on the same grid with antennas on the same towers or roofs, using the same juice, just transmitting and receiving at a different frequency. Use communication devices early and make the message count.
Ironically, telephone landlines don’t depend on the grid to work, they have always had their own low power and central station battery backup. If you still have a landline at home, then during an emergency try the landline number before cell phones. Telephones may be plugged in or have batteries to light up, run voicemail or other functions, but power isn’t needed for the actual call. Landline calls are less affected by interference or dropped calls. They can provide more clarity if you’re calling from a noisy location. Telephone poles and lines go down in storms like power ones do, so a specific neighborhood, or large part of town could lose landline telephone service. But most urban phone lines are protected underground.
Thanks for that fantastic information!
Hello,
I enjoyed reading your article, and your experience using Zello. I also utilize Zello. I mainly listen to Emergency and Weather channels. I downloaded the app about 7 years ago after a friend suggested it. I mainly would just chat with people.from around the world.
My reason for this comment is to say Zello has decided to remove the free Legacy desktop app. This terrible decision will prevent Users who currently simulcast on Emergency Alert free channels will no longer be able to do just this. A huge mistake on Zello’s part. Not everyone can afford to download the pay version of Zello. Many rely on these channels putting out these alerts. So, in conclusion, unfortunately Zello has gone downhill.
That’s not good news, and it’s kind of surprising. Free apps introduce potential customers to new technology and many go on to purchase. Thanks for letting me know.
