One recent deployment highlights just how critical the right hardware and network setup can be: a project involving autonomous oceanographic buoys designed to transmit real-time data from remote ocean regions. While Telecom26 was not involved in this specific use case, it clearly demonstrates the kind of environment where our global mobile connectivity solutions could bring added value — by ensuring resilient, multi-network access for devices that operate far beyond traditional coverage zones.

Leveraging marine-grade LTE antennas for signal strength was only part of the solution; ensuring that data could reliably reach its destination required the right mobile network infrastructure as well.

Where Telecom26 Can Make the Difference

At Telecom26, we provide multi-network global SIMs specifically built for maritime applications. That includes:

Multi-IMSI SIMs that switch between local and international networks for the strongest available signal

• Global roaming plans with predictable pricing — no shock data bills
• Seamless support for maritime routers, remote sensors, buoys, and onboard IoT systems
• Full remote SIM management via our SIM management platform

With our physical SIMs, deployed in rugged edge devices like routers and telemetry systems, your equipment stays connected from port to open sea with full visibility and control.

Real-World Example: Remote Marine Buoys

POYNTING’s latest case study showcases the critical role antennas play in enabling long-range wireless data transmission from smart buoys deployed by Mobilis S.A.

If you Pair this with Telecom26 SIM cards, you get:

• Reliable data links across coastal and offshore areas
• Seamless roaming without physical SIM swaps
• Centralized SIM lifecycle management for entire buoy fleets

 Designed for the Realities of Maritime Operations

Telecom26 Maritime SIMs are ideal for:

• Oceanographic sensors & buoys
• Crew connectivity
• Smart ports & logistics
• Offshore energy platforms
• Vessels in transit or docked

Whether you’re transmitting ocean data, tracking vessel systems, or keeping teams connected, Telecom26 gives you one SIM, one contract, one global service — no matter where your devices travel.
