1. The ship, the quay, and the box between them
Global shipping covers the shipping company, fleet management, port operations, seaborne cargo, and ship communications. A vessel on an international route has to stay on a shore VMS (vessel management system), a TMS (transportation management system), and the port VTS (vessel traffic service). The SIM is what the ship’s terminal, the container tracker, and the quay equipment use, on coastal and port networks, on one rate card.
SimtoLink supplies international IoT SIMs to shipping companies, shipowners, port operators, and ocean forwarders. Coverage is 200+ countries and regions and 600+ operator networks, as eSIM or physical SIM, for ship terminals, container trackers, and cargo-handling gear. Coastal and port coverage is the point: alongside, the ship takes the local network and the ship-to-shore sync actually finishes.
2. Dispatch, the crane, the box, and the crew
The work splits into fleet dispatch, port operations, seaborne cargo, and ship communications. How fresh the position has to be, how much data moves, and whether the ship is at sea or alongside are not the same:
Fleet management and dispatch
A ship’s VMS (vessel monitoring system) has to send position, speed, condition, and ETA so the route and the fuel figure can be worked. On a satellite/4G dual-mode link, the SIM keeps that sync going on an ocean passage, including tracking and dispatch for an ultra-large container ship. That is the online watch the IMO and SOLAS expect.
Port operations and cargo handling
A quay crane and a shore crane have to stay on the TOS (terminal operating system) and on remote monitoring, or the move rate slips. The SIM keeps the gear online for a live instruction, equipment status, and a handling-rate report. That is how a terminal chases TEU throughput without dropping the safety rule on the quay.
Seaborne cargo and containers
A dry box and a reefer have to stay online as they pass ports in more than one country. The SIM keeps the tracker and the temperature unit on the trail through loading, the sea leg, discharge, and the road move, and on the TMS and VGM (verified gross mass).
Crew communications, and 4G once alongside
On the high seas the ship uses satellite broadband for the crew. That link is part of crew welfare and of bridge automation. Alongside, the SIM moves the same traffic onto local 4G: crew calls, e-Navigation, and the shore sync, at a lower cost than satellite. That sits inside ITU maritime communication rules, and it is what keeps the crew connected and the ship-to-shore record complete.
3. Data per ship, most of it sent alongside
Each ship or device uses about 200MB–2GB a month. Most of that is periodic position, speed, and fuel; chart and weather updates; and a burst of sync when the ship is in port. The ship calls at ports in more than one country, so the terminal has to change networks on its own.
A shared pool fits a company with many ships and uneven use on each. The platform totals data by country and port and flags a spike. Sync while alongside and compressed reports keep the sea-leg bill smaller than a constant stream.
4. The position, the IMO kit, and salt air
- Ship and cargo data: Position and the cargo record are commercially sensitive. Send them on a private APN with TLS, in line with the GDPR and each country’s maritime data rules.
- IMO: The International Maritime Organization (IMO) requires AIS, LRIT, and related kit. The SIM is an extra ship-to-shore path beside that equipment, inside the same maritime rules.
- Ports in several countries: The terminal has to change networks on its own. One rate card covers those ports, and the bill is itemized, so a call does not become an unpriced roaming charge.
- Salt, shock, and temperature: Ship kit has to take salt fog, shock, and a wide temperature range. The SIM uses an industrial chip.
5. Cellular where the coast and the quay actually are
Coverage is 200+ countries and regions and 600+ operators, so a ship takes the best local network on a coastal passage or alongside. A shared pool absorbs the swing between vessels. Activation, plan changes, and fault checks for the fleet sit in one SimtoLink console. APIs connect that console to the VMS, the TMS, and the TOS.
6. Before the first call at a foreign quay
Count ships and devices, routes and ports, monthly data, and how the terminal joins the VMS and the TMS. From that, choose a single SIM or a shared pool, and pay-as-you-go or a monthly bundle. Test at the ports you actually call, against the local operators and your own systems. Activate SIMs, set the APN, and bind devices in bulk on the SimtoLink platform. After go-live, alert on data use, inspect on a schedule, and keep a response path when a ship stops reporting.
SimtoLink already supplies shipping companies and port operators. An API can tie the platform into the VMS, the TMS, and the TOS. If you are connecting a fleet or a quay, contact SimtoLink for a plan built around those ports.
