When cell towers go down or get overloaded, GMRS and HAM radio are the two main backup options for households. GMRS is easier to get started with — one license covers your whole family, and there is no test. HAM radio takes more study but gives you far more range and flexibility. Below is what each one actually requires, what it costs, and how to decide which fits your household.
Why Cell Phones Fail First
Cell networks are usually the first communication system to break down in a disaster. Towers can lose power, get physically damaged, or simply get flooded with more calls than the network can handle. Official guidance is direct about this: plan for phones and computers to be unreliable, and don’t assume you’ll be able to call for help.
- If calls won’t connect, try a text message first. Texts use far less bandwidth and often get through when voice calls can’t.
- Pick an out-of-area contact everyone in the household can call or text, since long-distance lines are sometimes less congested than local ones.
- Have a backup that doesn’t depend on the cell network at all — this is where GMRS and HAM radio come in.
GMRS vs. HAM Radio vs. FRS: Quick Comparison
- FRS: No license and no exam required. Anyone can use it. Short handheld range only, no repeater access.
- GMRS: License required, no exam. Covers the licensee plus immediate family under one 10-year license. Short-to-moderate range, with repeater access in some areas.
- HAM (Amateur) Radio: License and written exam required, one license per operator. Range varies by license class, from local VHF/UHF up to long-distance HF communication. 10-year license, free to renew.
For the wider gear picture, our prepper gear checklist covers where a radio fits alongside the rest of a basic emergency kit.
GMRS Radio: License, Cost and Range
GMRS (General Mobile Radio Service) is regulated by the FCC under Part 95. Here’s what to know before you buy:
- License: Required, but there is no exam. You apply directly with the FCC.
- Who can apply: Individuals 18 or older.
- Who’s covered: Once you’re licensed, your immediate family members can operate radios on your license too — you don’t each need a separate one.
- License term: 10 years, renewable.
- Cost: The FCC sets and updates the filing fee, so confirm the current amount on the FCC’s GMRS page before applying rather than relying on an older figure.
- Range: GMRS is a short-distance service. Handheld-to-handheld range is typically limited by line of sight and terrain — expect it to shrink in hilly or heavily built-up areas. Range can be extended using a repeater, where available.
HAM Radio: License Classes and What You Get
Amateur (HAM) radio is regulated by the FCC under Part 97. It requires more effort to get licensed than GMRS, but it opens up far more of the radio spectrum.
- License classes: Technician, General, and Amateur Extra, in order of increasing privileges. Most people start with Technician.
- Exam: A written, multiple-choice exam administered by volunteer examiners (VEs). There’s no minimum age — people as young as elementary-school age have passed the test.
- What Technician gets you: Full privileges on the VHF and UHF amateur bands, which is enough for most local and regional emergency communication and repeater use.
- License term: 10 years, renewable at no charge.
- Cost: The FCC currently charges an administrative fee for the license grant itself, separate from any fee your local volunteer examiner team charges to proctor the test. Confirm both current amounts before you register for an exam session.
- Range: Handheld VHF/UHF units behave similarly to GMRS for local range. The difference shows up as you upgrade: General and Extra class licenses unlock HF bands, which under the right conditions can carry a signal across the country or overseas — something no GMRS or FRS radio can do.

Which One Should You Get? A Simple Decision Path
- Just want the household to stay in touch during a local outage or evacuation? A GMRS license covers your family with no test required. Start here.
- Want to reach neighbors, a local emergency net, or use repeaters regularly? A Technician-class HAM license is a reasonable next step. The exam is straightforward with a few weeks of study.
- Want the ability to communicate long-distance if regional infrastructure is down for an extended period? Plan to study toward a General or Extra class HAM license, which unlocks HF bands.
- Not ready to license anyone yet? FRS radios need no license and work for short-range, line-of-sight chatter, but they offer less range and no repeater access.
Building a Backup Communication Plan
A radio only helps if your household knows how and when to use it. Official emergency planning guidance recommends putting a simple plan in writing:
- Agree on an out-of-area contact everyone can reach if local lines are down.
- Write down call signs, channels, or frequencies your household actually uses, and keep a copy with your emergency kit.
- Practice the plan at least once a year, the same way you’d practice a fire drill.
- Keep radios charged. If you’re also setting up backup power, our backup power load calculation guide walks through sizing a system that can keep communication gear running.

Extra Caution: Households With Specific Needs
- People with disabilities or access needs: Volunteer examiners are required to accommodate physical disabilities during HAM exams — ask your local VE team about this in advance.
- Households with young children or older adults: Keep instructions for the radio simple and posted near the unit, since the person using it in an emergency may not be the one who set it up.
- Rural or low-signal areas: Confirm realistic range for your specific terrain before relying on any radio as your only backup — advertised range figures assume open, flat conditions that rarely match real geography.
Evidence and Limits
Licensing rules, fees, and frequency allocations come from current FCC rules and are subject to change — always confirm details on the FCC’s own pages before applying or testing. Actual radio range depends heavily on terrain, elevation, weather, and equipment, so treat any range figures as a starting estimate rather than a guarantee.
Frequently Asked Questions
Do I need a license to use a walkie-talkie in an emergency?
Basic FRS walkie-talkies don’t require a license. GMRS radios, which offer more channels and often more power, do require an FCC license, though there’s no exam involved.
Can my whole family use one GMRS license?
Yes. A single GMRS license covers the licensee and their immediate family members, so you don’t need to license each person separately.
Is the HAM radio exam hard?
The entry-level Technician exam is a multiple-choice test built from a public question pool, and most people prepare with a few weeks of self-study using free practice tests. There’s no Morse code requirement.
Will HAM radio or GMRS work if the power grid is down?
Handheld radios run on batteries, so they work independently of grid power as long as you have a way to recharge them, such as a solar charger or backup power bank.
