In today’s digital era, maritime connectivity solutions and IoT deployments on the water demand connectivity that is secure, reliable and always accessible. Cellhire’s eSIMs, Fixed IP SIM cards and hybrid maritime solutions deliver on this promise by providing vessels with flexible cellular data, permanent IP addresses and satellite fallback, ensuring uninterrupted operations from port to open ocean.
Using SIM cards for offshore vessels offers cost-effective connectivity compared to LEO (Low Earth Orbit) satellite services, meaning that while SIM cards provide reliable connectivity, they are often more affordable, especially when considering global roaming and data costs. LEO satellites, while offering low-latency high-speed connectivity, can be more expensive, particularly for larger vessels or those requiring continuous high-bandwidth connections.

Why maritime connectivity matters
Cellular data usage at sea has grown significantly, particularly among vessels such as superyachts, cruise ships, and commercial cargo ships. These vessels often consume substantial amounts of data each month, with larger superyachts sometimes using multiple terabytes as backup connectivity while operating near coastlines. Cruise ships also rely on ship-based cellular towers to provide ongoing access to calls, texts, and mobile data, even while offshore. This connectivity is critical for enabling passenger services such as Wi-Fi, messaging, and entertainment streaming.
Modern maritime networks support both crew and passenger requirements. Onboard broadband solutions and maritime Wi-Fi networks ensure secure, high-speed connectivity for everything from video conferencing and VoIP to social media access and email communication. These services enhance passenger experience while improving crew welfare and morale during long voyages.
Beyond personal communication, maritime connectivity plays a vital role in operational efficiency and safety. Vessels use remote monitoring to track engine performance, cargo conditions, and route optimisation. Real-time alerts and automated systems help detect anomalies, ensuring safety and reducing downtime. Maritime IoT applications also enable smarter fuel usage, predictive maintenance, and centralised data management.
For both leisure and commercial operations, robust connectivity at sea is no longer a luxury but a necessity. It improves safety, boosts operational performance, supports digital transformation, and delivers the modern connectivity experience expected by crew and passengers alike.
Challenges of connectivity at sea
Maritime environments present unique hurdles:
- Coverage gaps: Some satellite services struggle to cover high-latitude or polar routes.
- High costs: Maritime satellite terminals can be expensive, with significant setup and running costs.
- Latency and bandwidth limits: Satellite connections can introduce delays, especially those relying on geostationary links.
- Network switching complexity: Crossing jurisdictions often requires managing multiple network partners, SIM swaps or fallback systems.
- Cybersecurity risks: Ships are increasingly targeted by cyber threats, requiring robust encryption and security protocols.
Connectivity solutions overview
Vessels typically leverage both satellite and cellular technologies to maintain continuous connections:
Satellite-based options
- GEO VSAT: Offers wide-area coverage but with high latency and premium costs.
- MEO services: Offer moderate latency and regional coverage with mid-tier hardware requirements.
- LEO constellations: Provide faster speeds and lower latency with global coverage but come with high hardware and subscription costs.
Cellular IoT SIM solutions
- Coastal 4G/5G roaming: Enables high-speed connectivity near shorelines and in port areas using multi-network SIMs.
- Security and management: Supports secure VPN tunnels, private IP allocation and centralised dashboards for monitoring.
Satellite vs cellular: a hybrid approach
- Primary cellular, fallback satellite: Enables cost-effective operations with seamless handover as vessels move offshore.
- Intelligent routing: Devices automatically select the optimal connection based on speed, cost and latency.
- Integrated billing: Unified dashboards consolidate costs across different providers and networks.
Cost analysis and flexibility
- VSAT only: Suitable for deep-sea missions but costly to install and maintain.
- Cellular only: Cost-effective and easy to deploy for coastal or short-range operations.
- Hybrid: Provides the best balance between cost, coverage and performance—ideal for a broad range of vessel types.
