Every option depends on something: towers, satellites, repeaters or your own batteries. Start simple, then add layers that don't share the same weak spot.
A common line in prepper circles is that cell phones are useless in a crisis. The record is more mixed. Most outages are short and local, and phones, texts and data often keep working through them. Long, wide outages are where networks start to struggle, as backup power and fuel run low.
So instead of picking one "best" radio, think in layers. Each layer leans on something different:
A good plan pairs at least one layer that reaches far with one that needs no infrastructure. The sections below walk through how each holds up, then the matcher helps narrow choices for your situation.
Your everyday phone on one carrier.
A walkie-talkie style radio that uses cell data.
One radio with PoC plus a regular UHF two-way radio.
License-free family radios.
Higher-power UHF radios for families and groups.
Classic 27 MHz radio, common with truckers.
Licensed radio across many bands.
Small text radios that pass messages node to node.
Devices that link to satellites instead of towers.
Satellite internet dish.
Receive-only broadcast radio.
Sometimes, but less often and less quickly than many assume. During California's 2019 wildfire shutoffs, 57% of cell sites in Marin County went down for a day. In response, the state now requires 72 hours of backup power at cell sites in high fire-threat areas.
Nationwide, carriers must let each other's customers roam when one network goes down in a declared disaster, and must report outage status to the FCC. When networks are busy, texts and short data bursts tend to get through better than calls.
| System | Backup | What it means |
|---|---|---|
| FirstNet (national public safety network) | 150+ portable cell sites on trucks and trailers, linked by satellite and not reliant on grid power | Sent to disasters within hours. Built for first responders, not public phone traffic, but it keeps rescue crews connected. |
| Cell networks during declared disasters | Carriers must allow roaming on each other's networks when feasible | Federal rule since 2022; helps radios and phones with multi-carrier SIMs. |
| Cell outages, nationwide | Carriers report outages to the FCC during major disasters | Recovery crews, portable towers and fuel trucks are prioritized. |
| Ham / GMRS repeaters | Up to the owner: batteries, solar or a generator — or none | Usually run by clubs or individuals. Ask your local club what theirs has. |
| Radio to radio (simplex) | Your own batteries and charging | No infrastructure to fail, but range is limited to line of sight. |
Ham and GMRS gear isn't automatically more resilient. A repeater is only as good as its owner's power setup; ham radio guidance treats batteries as the backbone of emergency power. Radio-to-radio contact needs no infrastructure at all, which is why it belongs in every plan.
These radios do two jobs. Over cellular, push-to-talk reaches your group anywhere with coverage. On the UHF side, they work like a regular two-way radio with no towers. For many households that one radio covers both everyday use and a local fallback.
Voice as data
A phone call holds an open line the whole time. PTT turns each transmission into short bursts of data, sent only while you talk. On a crowded network, small data bursts tend to get through when calls don't, the same reason texts often work when calls fail.
Universal and multi-carrier SIMs
A normal phone is tied to one carrier. If that carrier's local tower goes down, you lose service even when another carrier's tower nearby still works. A universal SIM can connect to whichever major or regional carrier has signal, so one carrier's outage doesn't knock you offline.
SkyCom PTT: what they list
How bridge mode works
The 6500 relays in both directions. Someone on a regular UHF radio near it talks, and the 6500 sends that audio to your PTT group nationwide. When a PTT user talks, the 6500 plays it out over UHF. One bridge radio, placed up high or in a vehicle, can link a group of simple UHF radios to people across the country. If the towers go down, it keeps working as an 8W local radio. Licensing rules apply to the UHF side .
We're testing the G8 now and the 6500 next, and will add results here. PrepFindr earns a commission on SkyCom sales.
Storm, fire or short outage
Cell and PTT usually keep working, sometimes congested. Text first and keep radios charged.
Regional outage (weeks)
Coverage gets patchy as backup power and fuel run thin. Local UHF and satellite text matter more.
Long-term grid down
Plan around radio-to-radio gear, your own charging and a printed plan.
Civil unrest
Networks may be busy or limited locally. Agreed channels and check-in times keep a group together.
1
Make a paper plan
Contacts on paper, an out-of-area check-in person, a meeting place and check-in times. Free, and it works with any gear.
2
Keep a weather / AM-FM radio
Alerts and news when nothing else works. Hand-crank or battery models cost little.
3
Add a dual-mode PTT + UHF radio
One radio covers nationwide push-to-talk while towers are up and local radio when they're not. A strong first radio for most households.
4
Grow local coverage
Add FRS/GMRS or ham handhelds for family members, or a mesh node for off-grid text. Practice monthly.

Cell phone (text first)
Already owned
Strength: Texts often get through when calls don't.
Weak spot: Needs working towers, backup power and the lines behind them.
PTT over cellular radio
$$ + service plan
Strength: Push-to-talk groups nationwide, light on data.
Weak spot: Still depends on cell towers being up.
Hybrid PTT + UHF radio
$$ + ~$40/yr service · license may apply
Strength: Nationwide on any carrier while towers work; local UHF when they don't. Some models bridge the two.
Weak spot: Nationwide side needs a working tower; UHF range is local.
Satellite messenger
$$$ + subscription
Strength: No ground towers needed; works with open sky.
Weak spot: Needs an active subscription; slow, short messages.
Satellite internet (Starlink)
$$$ + subscription
Strength: Full internet without local lines.
Weak spot: Power hungry; needs a clear sky view and subscription.
FRS walkie-talkies
$
Strength: No license, no towers, easy for kids.
Weak spot: Short range, especially around buildings and hills.
GMRS radios
$–$$ · license may apply
Strength: More power than FRS; repeaters can extend range.
Weak spot: Repeaters need their own backup power.
CB radio
$
Strength: No license; common with truckers on highways.
Weak spot: Noisy, and range varies a lot with antenna.
Ham VHF/UHF handheld
$ · license may apply
Strength: Cheap, flexible, large operator community.
Weak spot: Takes study and practice; repeaters vary in backup power.
LoRa mesh (Meshtastic/MeshCore)
$
Strength: Low-power, off-grid text; nodes relay for each other.
Weak spot: Range depends on terrain and nearby nodes.
Ham HF base/portable
$$–$$$ · license may apply
Strength: Regional to cross-country without infrastructure.
Weak spot: Steep learning curve, big antennas, conditions vary.
FRS, GMRS, CB, ham and LoRa mesh radios talk directly to each other. Range depends on antenna height and terrain more than the number on the box. Some services need a license .
