Emergency Communication

Why it matters

Disasters can knock out cell service, internet, and power in an instant, so it’s essential to prepare for emergency communication before you’re cut off. A solid plan keeps you connected with loved ones, ensures you receive vital updates, and helps you call for help when it matters most.

Build a Reliable Emergency Communication Plan

A reliable communication plan gives households clear steps to follow before, during, and after an emergency. Knowing how to reach one another, where to meet, and which backup options to use helps reduce confusion and supports faster, safer decision-making.

Establish Multiple Communication Methods

• Cell Phones: Ensure your phone is fully charged and you have a backup power source.
• Landline Phones: If you have a landline, keep it in working order.
• Satellite phones: These can be expensive but offer reliable communication in remote areas.
• Push-To-Talk (PTT) Walkie Talkie Apps: These require WiFi or cell networks, but require far less bandwidth than typical SMS/MMS

Have Backup Methods if Traditional Communication Goes Down

Create a Physical List of Emergency Contacts

• Include vital information: Your name, address, phone numbers of close family and friends, emergency contact information, and any medical conditions.
• Carry it with you: Keep the card on your person or in your wallet.
• Share with loved ones: Give copies to close friends and family.

Develop a Communication Plan

• Identify key contacts: Determine who you need to communicate with in an emergency.
• Establish meeting points: Decide on locations where you can meet if separated.
• Create a backup plan: Have a contingency plan in case your primary communication methods fail.
• Physical maps: Keep physical maps on-hand in the event your GPS does not work. You can request free maps from state tourism sites – see the full list of state sites here.

Designate an Out-of-State Contact

• Choose a trusted individual: Someone who lives outside your region and can act as a central point of contact.
• Inform them of your plans: Let them know about your communication methods and emergency plans.
• Provide their contact information: Share their details with friends and family.

Emergency Communication Apps

Some mobile apps provide additional ways to communicate when traditional calls or text messages are unreliable. These tools may use push-to-talk, Wi-Fi, Bluetooth, or mesh networking to send messages with less dependence on cellular service.

Emergency communication apps should be treated as supplements, not replacements, for primary communication methods like phones, radios, and in-person meeting plans.

Zello (Push-to-Talk over internet or Wi-Fi)

Zello works like a digital walkie-talkie, allowing users to send voice messages over Wi-Fi or cellular data. It can help families, neighbors, or response groups coordinate when networks are slow or congested but still functioning.

Because Zello depends on internet connectivity and device battery life, reliability may decrease during widespread outages or extended power loss.

Bridgefy (Bluetooth Mesh Messaging)

Bridgefy enables phones to send messages over Bluetooth by relaying signals from one device to another, forming a short-range mesh network. This approach can allow basic text communication between nearby users even when cellular service and Wi-Fi are unavailable.

Effective range depends on how many devices are participating in the network and the physical environment, which can influence overall message delivery.

Bitchat (Peer-to-Peer short-range messaging, such as Bluetooth)

Bitchat is designed for direct communication between nearby devices without relying on traditional cellular networks. Messages can be shared locally using short-range wireless connections, which may allow limited communication in areas where service is disrupted.

Range, device compatibility, and real-world reliability can vary based on surroundings and the number of participating devices.

Fernweh (offline-first local communication using short-range or local networking)

Fernweh focuses on offline-first communication designed to function with minimal network infrastructure. Features may include local message sharing, delayed synchronization, or low-connectivity operation suited for remote or disrupted environments.

Functionality and reliability depend on device support, configuration, and real-world conditions, so testing in advance helps set realistic expectations.

FRS Walkie-Talkies

Family Radio Service (FRS) walkie-talkies are one of the easiest backup communication tools for households because they do not rely on cell service, Wi-Fi, internet, or an individual radio license. They are commonly sold as consumer two-way radios and are best for short-range coordination with people who are already nearby.

FRS is useful for simple local communication: checking in between family members at home, coordinating between nearby vehicles during an evacuation, staying connected around a campground, or keeping a small group together when cell networks are congested. Range is often much shorter inside buildings, dense neighborhoods, wooded areas, or hilly terrain, so test radios where you actually expect to use them.

When FRS can help

• Short-range family communication: Useful when household members are nearby but cell service is weak or unavailable.
• Evacuation coordination: Helpful for keeping nearby vehicles in touch when traveling together.
• Apartment, dorm, or neighborhood use: Can support basic check-ins across a building, floor, block, or small local area when range allows.
• No individual license: FRS radios are licensed by rule in the United States, so compliant radios can be used by the general public without applying for a separate license.

FRS limitations

• Range is limited: Buildings, terrain, distance, and interference can reduce performance significantly.
• Everyone needs a radio: FRS only helps if the people you want to reach have compatible radios charged and ready.
• Channels are shared: Conversations are not private, and other nearby users may be on the same channel.
• Practice matters: Pick a default channel, label radios, test batteries, and make sure everyone knows how to use them before an emergency.

MURS Radios

Multi-Use Radio Service (MURS) is a short-range VHF radio option that can work without cell service, Wi-Fi, or internet. It is useful for simple local communication around a home, small property, campsite, farm, neighborhood, or event when everyone in the group has compatible MURS radios.

In the United States, MURS is “licensed by rule,” which means an individual FCC license is not required when you use compliant MURS equipment and follow the service rules. MURS operates on five VHF channels and is intended for short-distance voice or data communication.

When MURS can help

• Property and neighborhood coordination: MURS can be useful when people are spread across a small area but still within radio range.
• Backup family communication: It can provide a simple radio option if cell networks are congested or unavailable.
• Outdoor and rural use: VHF signals may perform well in some open areas, though buildings, hills, trees, and terrain can still reduce range.
• Low-burden setup: No individual license is required, but everyone must use MURS-compliant radios and follow the rules.

Limits to know before relying on MURS

• Not compatible with FRS or GMRS: MURS uses different frequencies, so it should be planned as its own radio option.
• Range is still local: Like other handheld radios, real-world range can be much shorter than package claims, especially indoors or in dense neighborhoods.
• Adoption is lower: FRS and GMRS radios are more common, so MURS is most useful when your own household or group intentionally chooses it.
• Use approved equipment: Do not rely on programmable radios unless they are legal and configured properly for the service.

General Mobile Radio Service (GMRS) Licensing

General Mobile Radio Service (GMRS) provides short-range two-way radio communication that can work independently of cellular networks. GMRS radios are commonly used by families, outdoor groups, and community teams for local coordination during emergencies or power outages.

Because GMRS operates on licensed radio frequencies, obtaining a simple FCC license is required before use in the United States.

What is GMRS?

What is GMRS Used For?

• Family communication: Keeping in touch with family members while they’re out and about, especially during emergencies or outdoor activities.
• Group communication: Coordinating activities with friends, clubs, or organizations.
• Business communication: Communicating between employees or between a business and its customers.
• Emergency communication: Providing a backup local communication system during disasters or power outages.

How To Obtain a GMRS License

• Familiarize yourself with GMRS and best practices. While it doesn’t take much to get a license, there is an etiquette to communicating via GMRS (including knowing/addressing yourself by your call sign). Remember, these frequencies are public – and if you’re not careful/respectful, you can upset other locals without knowing the basics before you decide to communicate.
• Register an FRN number with the FCC Commission Registration System (CORES)
• Log in to the FCC’s License Manager and apply for a General Radio License (GMRS) for $35

HAM (Amateur) Radio Licensing

Amateur (HAM) radio enables long-distance communication using licensed radio equipment and established operator networks. During large-scale emergencies, HAM radio operators often support community coordination, emergency messaging, and situational awareness when other communication systems fail.

Licensing requires passing a basic knowledge exam, but it provides access to powerful communication capabilities that extend well beyond local radio range.

What is HAM?

HAM radio is a shortened term for Amateur Radio. It is a hobby and public-service communication method that uses radio waves to connect with other operators locally, regionally, and around the world.

What is HAM Used For?

• Communication: Connecting with people from all over the world, sharing experiences, and building friendships.
• Emergency communication: Providing a vital lifeline during disasters when other communication channels fail.
• Experimentation: Exploring different radio frequencies, technologies, and operating modes.
• Contesting: Participating in competitions to see how many contacts can be made in a specific time period.
• Education: Learning about electronics, radio technology, and communication systems.
• Public service: Assisting with various community events and projects.

How To Obtain a HAM License

HAM radio licensing is more extensive than GMRS. This license opens the door to worldwide communications and requires passing a 35-question written exam held by a Volunteer Examiner Coordinator.

To obtain a HAM license:

1. Review HAM radio resources from the National Association for Amateur Radio
2. If possible, join a local amateur radio club. The best way to learn is from experienced operators and attend their training workshops.
3. Find a license exam in your area.
4. Study for the exam (apps like HAM Study can be helpful for practicing test questions)
5. Pass the written exam

Do emergency communication apps work without cell service?

Some emergency communication apps can function with limited or no cellular service by using Wi-Fi, Bluetooth, or short-range peer-to-peer connections. However, performance varies, and apps should be treated as supplemental tools rather than primary emergency communication methods.

Do FRS walkie-talkies require a license?

In the United States, FRS radios are licensed by rule, which means the general public can use compliant FRS devices without applying for an individual FCC license. FRS is best for short-range local communication, and users should follow the device instructions and service rules.

What is MURS and when is it useful?

Multi-Use Radio Service (MURS) is a short-range VHF radio service that does not require an individual FCC license when compliant equipment is used under the rules. It can be useful for local household, property, campsite, or neighborhood communication, but it is separate from FRS and GMRS and requires compatible MURS radios.

What is GMRS and when is it useful?

General Mobile Radio Service (GMRS) is a licensed two-way radio system that allows short-range communication independent of cellular networks. GMRS radios are commonly used by families, outdoor groups, and community teams for local coordination during emergencies or power outages.

What is HAM radio used for in emergencies?

HAM radio can be used to send and receive messages when cell service, internet, or landlines are unavailable. Licensed amateur radio operators may help relay emergency traffic, weather reports, welfare checks, and coordination updates through local repeaters, emergency nets, and amateur radio organizations.

Do you need a license to use emergency radios?

Some radio services require licenses. GMRS requires a simple FCC license in the United States, while HAM radio requires passing a basic knowledge exam. Other radios, such as FRS walkie-talkies, do not require a license but typically have shorter range and fewer capabilities.

What should be included in a family communication plan?

A family communication plan should include primary and backup contact methods, an out-of-state contact person, meeting locations, written emergency contact lists, and clear instructions for how family members will reconnect if separated during an emergency.
