So, it costs a fortune to use your cell phone on a cruise ship, but you still want to keep in touch with your friends or family. How do you find out where they are so you can meet up? 
For many people, walkie talkies are still the answer. As long as you don’t disturb other passengers, they can be a great way to communicate a change of plans or find your party.
But which walkie talkies work best? In 2026, some are a complete waste of money because they can’t punch through the heavy steel walls of a modern mega-ship, and others might actually get you in trouble at security. Here is what to look for and the 2-way radios I recommend.
What to Look for in a Good Walkie Talkie
Weather Resistance
Since you will be surrounded by water, look for a radio that is JIS4 certified or higher. This means it can handle a stream of water or a splash from the pool. While you can’t submerge most of them, they will stay functional even with the salty ocean spray.
Privacy Features
You don’t want to eavesdrop on every other family on the ship. Look for radios with privacy channels and interference removal codes. Many modern units offer over 120 privacy codes to keep your frequency clear.
Effective Range
Many radios promise a range of 30 miles or more. Realistically, you won’t get that distance on a ship. However, radios rated for high mileage typically have the power needed to work through the steel structure of the decks.
Vibration and Text Alerts
In 2026, etiquette is everything. I prefer a walkie talkie with a vibration alert or a text messaging feature. It makes communication much less intrusive in public areas, and those texts are completely free from roaming charges.
The Most Common Types of Radios at Sea
FRS Radios
FRS (Family Radio Service) radios are the “budget” option. They are often not powerful enough to work across different decks of a ship. You might be able to talk if you are both in the buffet, but don’t expect them to work from the stateroom to the lido deck.
FRS/GMRS Radios
These are a better compromise for cruisers. GMRS (General Mobile Radio Service) channels are more powerful and better at penetrating steel. Note for 2026: You do need a license from the FCC to use GMRS frequencies. The good news is the fee has dropped to $35, it lasts for 10 years, and it covers your entire immediate family.
Digital (900MHz) Radios
These use Frequency Hopping Spread Spectrum (FHSS) technology. They are becoming the gold standard on ships because they don’t require a license, and they work significantly better through steel and concrete walls than traditional analog radios.
Are They Allowed? (The 2026 Rules)
While most cruise lines like Royal Caribbean and Carnival allow walkie talkies (as long as they are under 5 watts and have no external antennas), some lines have changed their stance.
Norwegian Cruise Line has officially added walkie talkies to their prohibited items list. Always check your specific cruise line’s “Banned Items” list before you pack, or security might hold your radios until the end of the trip!
Disclaimer: Always check the laws of the countries you are visiting. US-spec FRS/GMRS frequencies are often reserved for emergency services in Europe and the UK. Using them on a Mediterranean shore excursion could result in heavy fines.

What brands/models are there for the erxs with text messaging capabilities?
The general advice in this article is true but as a radio tech let me assure you that no radio of any type will work through a solid steel wall. No penetration, none at all, period. An interior cabin with the door closed is a good approximation of a Faraday Cage, essentially a trap for all radio signals. Any signals you get from inside your cabin or inside the ship will be from reflections bouncing under the door, down passageways, out your balcony or refracting around the edge of your window and reflecting off of bits of metal on the ship superstructure. It is a testament to how sensitive radios are these days that even those extremely weak reflected signals can allow you to communicate. Also, 900 MHz may work better because the higher the frequency the better the signals reflect off metal surfaces. Fortunately for cruisers it is very hard to completely eliminate all signal paths, and of course the comments about higher power being better makes perfect sense in that context.
