One of the most common questions about the Talkpod N39plus is whether it only works nationwide or whether it can actually communicate internationally.

The answer is simple:

The N39plus is not limited by traditional radio-to-radio distance. As long as both users have compatible internet access and can connect to the VHAM platform, they can communicate across cities, states, countries, and potentially around the world.

Unlike a conventional VHF/UHF handheld radio, the N39plus does not rely on a direct RF signal between two radios. Instead, it uses cellular data and the internet to connect to the VHAM communication platform.

That is what we mean by “unlimited range.”

What Does “Unlimited Range” Actually Mean?

Traditional handheld radios are limited by factors such as:

Transmit power
Antenna height
Terrain
Buildings
Distance
Repeater coverage

The N39plus works differently.

Its communication path is:

N39plus → Cellular Network → Internet → VHAM Platform → Internet → Receiving Device

Because communication is carried over the internet, there is no traditional RF distance limit between users.

For example, one user could be in:

California

while another user is in:

New York

or even:

Germany

and both could participate in the same VHAM Talk Group, provided they each have a working internet connection and access to the VHAM service.

So the practical range of the N39plus is determined by network connectivity, not by direct radio distance.

Nationwide or Global?

The N39plus can support both.

Nationwide Communication

Users in different cities or states can communicate through the same VHAM Talk Group.

For example:

Los Angeles → New York

Texas → Florida

As long as both radios are connected to the VHAM platform, physical distance between them is not a major limitation.

Global Communication

VHAM groups are not restricted to one country.

Users in supported regions can participate in the same Talk Group through the internet.

For example:

United States → Canada

United States → Germany

United Kingdom → Japan

The important requirement is that each device has:

Compatible cellular or internet access
An active data connection
Access to the VHAM platform
The correct Group ID

Your Group ID Defines Who You Talk To

Although the N39plus can communicate over very long distances, that does not mean every transmission is automatically heard by everyone around the world.

Your audience is determined by the VHAM Talk Group you join.

VHAM uses a 6-digit Group ID.

For example:

582731

Users who enter the same Group ID can communicate with one another through that group.

The group may be:

A family group
A local club group
A state or regional group
An amateur radio interest group
An event group
A business team
An international community
A global public group

The geographic distance between group members does not determine whether they can communicate.

The Group ID and network connection do.

How Public Groups Work

VHAM includes Public Groups that users can join by entering the corresponding Group ID.

When you transmit in a Public Group, other users who are currently online in that same group may hear your transmission and respond.

This creates an experience that will feel familiar to many radio enthusiasts.

However, unlike conventional shortwave or VHF/UHF radio, the signal itself is not traveling directly over the air between users.

The voice communication is being routed through cellular networks and the VHAM internet platform.

This distinction is important when understanding how the N39plus achieves long-distance communication.

Private and Small Groups

Not every VHAM group needs to be public.

You can also create a group specifically for:

Family members
Friends
Radio clubs
Travel groups
Event staff
Business teams

Simply share the same 6-digit Group ID with the intended users.

For additional group separation, the N39plus can also use a 2-digit virtual code.

For example:

Group ID: 582731
Virtual Code: 26

All intended users should enter the same settings.

What Determines N39plus Coverage?

Although the communication distance itself is not limited like a traditional handheld radio, the N39plus still requires network access.

Normal operation depends on:

Cellular coverage
SIM data service
Carrier availability
Internet connectivity
VHAM platform availability

If your radio is in an area without compatible cellular coverage, it cannot connect to the VHAM platform until internet access becomes available again.

So a more accurate way to describe the N39plus is:

Wide-area and global communication wherever compatible internet connectivity is available.

International Travel with the N39plus

The VHAM platform itself can be accessed internationally, but your SIM service may have regional coverage limitations.

For example, an N39plus purchased for use in North America may include a VHAM SIM primarily configured for North American cellular networks.

When traveling to another country, your radio may display:

Searching

Offline

if the installed SIM does not have service in that region.

This does not necessarily mean there is a problem with the radio or VHAM account.

It may simply mean that your current SIM does not have international roaming access.

There are two main ways to use the N39plus when traveling internationally.

Option 1: Add an International Roaming Package

Before traveling, you can contact Talkpod Support to check whether international roaming service is available for your destination.

Depending on the destination and current service options, a temporary roaming package may be available for your existing VHAM SIM.

This allows you to keep using the same SIM while traveling.

Once the radio registers with a supported roaming partner, it can reconnect to VHAM and continue using the same:

Call Sign
Group ID
Virtual Code
VHAM groups

International roaming is a separate service and may involve additional charges.

For current availability and pricing, contact:

support@talkpod.com

Option 2: Use a Local SIM Card

The N39plus supports compatible third-party Nano SIM cards.

When traveling, you may be able to purchase a local prepaid data SIM and install it in the radio.

You may also be able to use another compatible data SIM that provides normal internet access.

The basic requirement is:

The SIM must provide compatible mobile data and internet access.

Once the radio has an active data connection, it can connect to the VHAM platform and communicate with your existing groups.

For example:

You normally use your N39plus in the United States.

You travel to Germany and install a compatible German prepaid data SIM.

Your N39plus connects to the local cellular network and then logs back into VHAM.

You can still communicate with users in your regular VHAM group back in the United States.

The cellular carrier changed.

Your VHAM group did not.

Do I Need to Create a New Account When Traveling?

No.

Changing cellular networks does not normally require you to create a new VHAM account.

Your VHAM configuration and cellular connection perform different functions.

Think of it this way:

SIM / Cellular Network = Provides Internet Access

VHAM = Provides Push-to-Talk Communication

As long as the N39plus can establish a compatible internet connection, it can attempt to reconnect to VHAM.

Will My Group ID Change in Another Country?

No.

Your Group ID is not tied to a specific cellular carrier or country.

For example, if your normal group is:

582731

you can continue using:

582731

while traveling, provided the radio can connect to VHAM.

Other members do not need to change their radios simply because you are in another country.

Example: Using N39plus Across Countries

Imagine three radio users:

K1ABC — United States

M0ABC — United Kingdom

DL1ABC — Germany

All three radios are connected to the internet and all three users enter:

Group ID: 582731

They can participate in the same VHAM Talk Group despite being located in three different countries.

This is one of the key differences between PoC communication and conventional direct RF handheld radio communication.

Is N39plus the Same as Shortwave Radio?

No.

The user experience may sometimes feel similar because people from different locations can join a common group and communicate with one another.

However, the underlying technology is completely different.

Traditional shortwave communication uses radio-frequency propagation directly between stations.

The N39plus uses:

Cellular Data + Internet + VHAM Servers

This provides predictable wide-area communication where suitable cellular or internet connectivity is available, but it also means the radio depends on network infrastructure.

What Happens If There Is No Cellular Service?

Without compatible cellular data, the N39plus cannot communicate through VHAM.

It is therefore different from a conventional VHF/UHF radio, which can still communicate directly between radios without internet access.

This makes the two technologies useful for different situations.

N39plus PoC

Best suited for:

Cross-city communication
Nationwide teams
International groups
Distributed businesses
Families living in different areas
Internet-connected radio communities

Traditional VHF/UHF Radio

Best suited for:

Off-grid communication
Local simplex operation
Areas without cellular coverage
Amateur repeaters
Emergency backup communications

For some users, the two systems complement each other rather than compete directly.

Frequently Asked Questions

Is the N39plus truly unlimited range?

There is no traditional radio-to-radio RF distance limit.

Communication can take place over very long distances through the internet, provided all participating devices have compatible network access.

Can I talk from the United States to Europe?

Yes, provided both users can connect to the VHAM platform and are using the same Talk Group.

Does international communication cost extra?

VHAM group communication itself does not change based on the distance between users.

However, the cellular SIM used to access the internet may have different data or roaming charges depending on the country and service plan.

Can I use my N39plus while traveling internationally?

Yes, provided you have compatible data service.

You can either use supported international roaming or install a compatible local Nano SIM.

Will I lose my Talk Groups if I change SIM cards?

Normally, no.

The cellular SIM provides network connectivity, while your VHAM group settings are handled separately by the device and platform.

Can I communicate without cellular coverage?

No.

The N39plus requires compatible data connectivity to access the VHAM platform.

Global Communication Without Traditional RF Distance Limits

The N39plus is designed for users who need communication beyond the normal range of a handheld radio.

Instead of asking:

“How many miles can this radio reach?”

a better question is:

“Do both users have compatible internet access?”

If the answer is yes, the physical distance between them becomes far less important.

Whether your group members are across town, across the country, or across the world, VHAM allows compatible users to communicate through the same Talk Group.

The basic formula is:

Internet Access + VHAM + Same Group ID = Wide-Area Communication
