Choosing the Right Satellite Phone for Your Boat

As you embark on your sailing adventure, leaving the rat race behind and embracing the open sea, communication becomes a crucial aspect of your journey. While you may be seeking solitude and tranquility, staying connected to the world is essential for safety, weather updates, and staying in touch with loved ones. One of the most reliable ways to maintain communication while sailing is through a satellite phone. In this article, we will explore the various factors to consider when choosing the right satellite phone for your boat.

Why a Satellite Phone?

While cellular networks and Wi-Fi connections are widely available in coastal areas and marinas, their coverage quickly diminishes as you venture further offshore. Satellite phones, on the other hand, provide global coverage, allowing you to make calls, send text messages, and access data services from virtually anywhere in the world.

In addition to their extensive coverage, satellite phones offer several other advantages:

  • Reliability: Unlike cellular networks, which can be affected by weather conditions, satellite phones are less susceptible to interference and provide a more stable connection.
  • Emergency communication: In case of an emergency, a satellite phone can be a lifesaver, allowing you to call for help and provide your location to rescue services.
  • Weather updates: Access to up-to-date weather information is crucial for safe sailing. Many satellite phones offer weather services, ensuring you’re always aware of changing conditions.
  • Peace of mind: Knowing that you can stay in touch with family and friends, even in the most remote locations, provides a sense of security and comfort during your sailing adventure.

Types of Satellite Phones

There are two main types of satellite phones: handheld and fixed. Each type has its advantages and disadvantages, depending on your needs and preferences.

Handheld Satellite Phones

Handheld satellite phones are portable devices similar in size and appearance to a traditional mobile phone. They are designed for use on land, at sea, and in the air, making them a versatile option for sailors.


  • Portable and easy to use
  • Can be used on multiple boats or during shore excursions
  • Battery-powered, allowing for use during power outages


  • May require an external antenna for optimal reception on a boat
  • Limited battery life compared to fixed satellite phones

Fixed Satellite Phones

Fixed satellite phones are permanently installed on your boat and connected to an external antenna. They often come with additional features, such as a docking station and handset, providing a more comprehensive communication solution.


  • Better signal strength and reception due to external antenna
  • Can be integrated with other onboard communication systems
  • No need to worry about battery life


  • Less portable than handheld satellite phones
  • Installation can be more complex and time-consuming

Coverage and Network Providers

When choosing a satellite phone, it’s essential to consider the coverage provided by different network providers. There are four main satellite networks that offer global or near-global coverage:

  1. Iridium: Offers truly global coverage, including the poles. Iridium is the only network that provides coverage in the most remote areas of the world, making it the top choice for sailors venturing far from established routes.
  2. Inmarsat: Provides near-global coverage, excluding the polar regions. Inmarsat is a popular choice for sailors cruising in well-traveled areas, as it offers reliable coverage and a range of services.
  3. Globalstar: Offers regional coverage in North America, Europe, and parts of South America, Africa, and Asia. Globalstar is a more affordable option for sailors staying within its coverage area but may not be suitable for those planning to sail further afield.
  4. Thuraya: Covers Europe, Africa, the Middle East, Asia, and parts of Australia. Thuraya is a good option for sailors in these regions but may not be suitable for those planning to cross oceans or sail to the Americas.

It’s essential to research the coverage and network reliability of each provider before making a decision, as this will directly impact your ability to communicate while at sea.

Key Features to Consider

When choosing a satellite phone, there are several key features to consider, depending on your needs and preferences:

  • Voice and data capabilities: Most satellite phones offer voice calling and text messaging, but data capabilities can vary. If you require internet access for email or weather updates, ensure the satellite phone you choose supports data services.
  • Battery life: For handheld satellite phones, battery life is an important consideration. Look for models with long-lasting batteries and the option to use external power sources, such as solar chargers.
  • Durability and water resistance: Sailing can be tough on your equipment, so it’s essential to choose a satellite phone that can withstand the elements. Look for models with rugged designs and water-resistant features.
  • Ease of use: A user-friendly interface and simple navigation are important, especially in emergency situations. Test out different models to find one that feels intuitive and easy to use.
  • GPS capabilities: Some satellite phones come with built-in GPS, allowing you to track your location and share it with others. This can be a valuable safety feature, particularly in emergencies.

There are several satellite phone models on the market, each with its own set of features and capabilities. Some popular options include:

  • Iridium 9575 Extreme: A rugged and reliable handheld satellite phone with global coverage, GPS capabilities, and emergency SOS button. The 9575 Extreme also supports data services, allowing you to access email and weather updates.
  • Inmarsat IsatPhone 2: A durable and easy-to-use handheld satellite phone with near-global coverage. The IsatPhone 2 offers voice calling, text messaging, and basic data services, as well as GPS capabilities.
  • Globalstar GSP-1700: A compact and affordable handheld satellite phone with regional coverage. The GSP-1700 provides voice calling and text messaging but does not support data services.
  • Thuraya XT-PRO: A feature-rich handheld satellite phone with coverage in Europe, Africa, the Middle East, Asia, and parts of Australia. The XT-PRO offers voice calling, text messaging, and data services, as well as GPS capabilities and a built-in compass.

Accessories and Add-ons

To enhance the functionality and convenience of your satellite phone, consider investing in some useful accessories and add-ons:

  • External antenna: An external antenna can significantly improve the signal strength and reception of your satellite phone, particularly on a boat. Many handheld satellite phones can be connected to an external antenna for better performance.
  • Docking station: A docking station allows you to use your handheld satellite phone as a fixed phone, providing a more stable connection and the option to integrate with other onboard communication systems.
  • Solar charger: A solar charger can help keep your handheld satellite phone powered during long voyages or in case of power outages.
  • Protective case: A durable and water-resistant case can help protect your satellite phone from the elements and extend its lifespan.

Costs and Subscription Plans

The cost of a satellite phone can vary widely, depending on the model, features, and network provider. In general, handheld satellite phones can range from $500 to $1,500, while fixed satellite phones and systems can cost several thousand dollars.

In addition to the upfront cost of the phone, you’ll also need to consider the ongoing costs of a subscription plan. Satellite phone plans can be either prepaid or postpaid and typically include a monthly fee, as well as charges for voice calls, text messages, and data usage. Plans can range from as little as $30 per month for basic services to several hundred dollars per month for more comprehensive plans with higher usage allowances.

It’s essential to carefully consider your communication needs and budget when choosing a satellite phone and subscription plan, as the costs can add up quickly.


Choosing the right satellite phone for your boat is a crucial decision that can greatly impact your safety, comfort, and enjoyment during your sailing adventure. By considering factors such as coverage, network reliability, key features, and costs, you can find the perfect satellite phone to keep you connected and informed, no matter where your journey takes you.
