Emergency Communications
When Cell Networks Go Down
Cell networks are often the first thing to fail in a major emergency. Tower damage, power outages, and network congestion can all cut you off. Here's how to plan ahead so your family stays connected regardless.
Power Outage, Network Outage, or Overload? Send a Text — Not a Call.
Voice calls need a dedicated circuit for their entire duration — if the network is full, your call fails immediately. SMS texts are tiny (~140 bytes) and get queued automatically, pushing through any brief gap that opens up. They don't need a reserved channel.
Use this order during any emergency:
- SMS/text first — smallest footprint, queues automatically, works on any phone
- WhatsApp, iMessage, or Signal over Wi-Fi — bypasses cell entirely if home internet is up
- Short voice call — keep under 30 seconds if you get through; don't tie up the circuit
- Wi-Fi calling or FaceTime Audio — if cell is down but Wi-Fi is working
💡 Extra tip: Text an out-of-area contact in another city or province — long-distance routing often has capacity when local circuits are jammed. Also remember: texts may be delayed minutes to hours but they will arrive when the network recovers.
Why Cell Networks Fail
Understanding the failure modes helps you choose the right backup. Cell towers have limited battery backup — typically only 4–8 hours without grid power.
💡 See above: During any network failure or congestion, send a text/SMS before attempting a call — see the full explanation and priority order at the top of this page.
Alternative Communication Methods
Layer multiple methods — start with the simplest and most infrastructure-independent, work up to more complex tools.
Two-Way Radios (Walkie-Talkies)
FRS/GMRS radios work radio-to-radio with no infrastructure at all. Keep a set charged or use AA/AAA batteries.
- FRS radios: 1–2 km range, no licence required in Canada
- GMRS radios: up to 40+ km range (requires ISED licence in Canada)
- Best for neighbourhood and family coordination within a few kilometres
- One per family member or household — practice using them before an emergency
Satellite Communication
Works completely independently of cell towers and ground infrastructure.
- Satellite phones (Iridium, Inmarsat) — voice calls anywhere in Canada
- Garmin inReach / Zoleo — two-way texting + SOS via Iridium (full Canadian Arctic coverage)
- iPhone 14+ Emergency SOS via satellite — built-in, available in Canada
- Starlink — portable dish provides broadband even when cell/landline is down
Traditional Landline Phones
Copper-wire landlines often survive when cell networks fail completely.
- A corded phone plugged directly into a wall jack may still work
- Important: VoIP landlines (Xfinity, Rogers Home Phone, etc.) do NOT work in a power outage — they require power and internet
- If you have copper service from Bell or a local telco, keep one corded phone
AM/FM & Weather Radio
Battery or hand-crank radios receive emergency broadcasts — no infrastructure needed.
- Environment Canada broadcasts 24/7 on Weatheradio Canada frequencies
- One-way (receive only) but critical for situational awareness
- Get a hand-crank / solar model — works without batteries or power
- Keep one in your 72-hour kit and one in your vehicle
Wi-Fi Calling & Messaging Apps
If your home internet or a neighbour's Wi-Fi is still working, use it.
- Wi-Fi Calling — enable in your phone's Settings so calls route over Wi-Fi
- WhatsApp, Signal, Telegram — work over Wi-Fi without any cell service
- iMessage and FaceTime work over Wi-Fi when cellular is down
- Email works over Wi-Fi — useful for longer status updates
Physical Rally Points
The most reliable plan requires no technology at all — just a shared agreement made in advance.
- Designate a primary rally point near home everyone knows to go to
- Designate a backup rally point farther away (relative's house, community centre)
- Agree on a check-in schedule (e.g. every 6 hours at the rally point)
- Designate an out-of-area contact — long-distance calls often go through when local lines are jammed
Vehicle CB Radio
Citizens Band radio requires no licence in Canada, works car-to-car and with truck drivers.
- Good for road travel during emergencies — check on routes and conditions
- Channel 9 is the international emergency channel
- Range: approximately 5–15 km depending on terrain
Mesh Networking Apps
Phone-to-phone mesh networks that work with no cell towers, no Wi-Fi, and no internet — phones relay messages through each other.
- Meshtastic — best range, uses cheap LoRa radio hardware (~$35 CAD) paired with free app. Range 3–15+ km per node. Community networks growing across Canada
- Bridgefy — Bluetooth mesh, no hardware needed. Range ~100m per hop but messages relay through multiple phones. Free app for iOS and Android
- Briar — secure encrypted messaging over Bluetooth or Wi-Fi direct. No accounts, no servers. Android only
- goTenna Mesh — dedicated hardware + app. Range 6+ km per node, pairs with smartphone
Ham (Amateur) Radio
Extremely robust — local repeaters extend range to 80–160+ km. Requires an ISED amateur radio licence (basic exam).
- Ham operators often serve as emergency communication volunteers (ARES)
- Local repeaters stay operational on backup power during grid outages
- Basic licence exam is free to study for — study guides available at rac.ca
- A handheld HT radio costs $40–$80 CAD
Satellite Communication Options for Canada
Canada's vast geography and remote communities make satellite especially important. Only Iridium and Starlink provide reliable coverage above 70°N in the Arctic.

Bridgefy — No Hardware Option
If you want mesh networking with zero extra hardware, Bridgefy is the best phone-only option. It uses Bluetooth Low Energy — range is much shorter than Meshtastic (60–100m per hop) but in a neighbourhood or apartment building with multiple users it can build a viable relay network.
Getting Started with Bridgefy
- Download Bridgefy free from the iOS App Store or Google Play
- Open the app and create a username — no phone number or email required
- Enable Bluetooth on your phone
- You can now message anyone nearby using Bridgefy — no internet needed
- Broadcast mode sends to all nearby Bridgefy users simultaneously — useful for emergency announcements
- Important: The more people in your area who have the app installed, the farther and more reliably messages travel — encourage neighbours to install it in advance
Practical Tips for Canadian Families
- →Pre-install with neighbours now — mesh apps only work if multiple people in your area have them. Organize a neighbourhood preparedness session and install together
- →Meshtastic node at home — a solar-powered Meshtastic node mounted outdoors extends your local mesh year-round and helps build community coverage
- →Test it before you need it — run a family drill using only the mesh app to communicate. This reveals range limitations and workflow gaps in advance
- →Keep LoRa device charged — treat it like your walkie-talkie. Charge monthly or run it on USB power bank
- →Canadian regulations — Meshtastic operates on the 915 MHz ISM band in Canada, which does not require a licence. It is legal for general use under ISED general licence exemptions

📚 Knowledge & Skills
The layered approach: The best emergency communication plan layers multiple methods — rely on the simplest and most infrastructure-independent option first (rally point, walkie-talkie, hand-crank radio), then work up to more complex tools (satellite messenger, Ham radio). No single method is enough on its own. Practice your plan before an emergency so it becomes second nature.
