1. A crane that still has to take the next move when the ship is alongside
International port equipment covers quay handling, the yard, container tracking, port management, a TOS (terminal operating system), an RTG (rubber-tyred gantry), and an AGV. Port operators and shipping lines place handling gear, yard equipment, and container trackers in many countries, and each one has to reach headquarters and the port platform while the ship is working. The SIM is what keeps that machine online, so it has to work in every country on the terminal estate, stay available around the clock, and survive a quay.
SimtoLink supplies international IoT SIMs to cross-border port operators, shipping lines, and port-technology firms. Coverage spans 200+ countries and regions and 600+ operator networks, as eSIM or physical SIM, for handling gear and yard equipment. One SIM stays in the machine when it is moved to another terminal. EDI, a live sailing schedule, and slot management still have to run on the clock the terminal expects.
2. The crane, the berth, the box, and the fault
Port equipment covers quay handling, the yard, container tracking, and remote maintenance. How fast the answer has to come is not the same on each machine:
Quay handling and the cranes
A quay crane (QC) and a rubber-tyred gantry (RTG) join the TOS for a live move order — lift, set down, shift — and for job status: container number, crane position, spreader load. An automated RTG expects the control command in under 100 ms. The SIM sits on the terminal’s private LTE, with a second operator behind it so a move does not stop. Productivity goes to the port-authority platform, which is what the KPI is scored on.
The yard and the warehouse
A VTS (vessel traffic service) pulls AIS, radar, and cameras and sends ship movement — position, speed, destination — and berth occupancy to the port control center. That is what drives berth planning: the booked time alongside and the queue to leave. An intelligent pilotage feed puts draft, list, and handling notes on the pilot’s terminal. A port AGV expects the TOS order — the path and the priority for avoiding a conflict — in under 200 ms.
Container tracking and the slot
A container tracking system uses RFID, Bluetooth beacons, and an IoT tracker to keep a box visible in the yard as a 3D slot, at the gate on the way in or out, and on the ship in its stow. All of that lands on the port TOS. License-plate recognition (LPR) and container-number recognition (OCR) at the gate sync to customs EDI, which is how paperless release and pre-clearance stay ahead of the truck.
Remote maintenance and fault diagnosis
Hydraulics, gearboxes, and motors on quay cranes, gantries, terminal tractors, and forklifts report vibration, temperature, and oil pressure to the port asset platform (EAM). That is preventive maintenance (CBM), and remote diagnosis when a vendor engineer reaches the PLC over a VPN. An offline alarm raises a work order and assigns it to the terminal crew. A group that runs terminals in several countries puts every machine on the headquarters EAM through the same SIM estate.
3. Data per machine
Each machine uses about 500MB–5GB a month. Most of that is move orders and status, video and fault diagnosis, TOS and EDI, plus AGV paths and slot data. A terminal runs around the clock, so leave 20%–30% of headroom. Resume after a break and compressed reporting bring the cost of a large file down.
Several SIMs can share one pool, which fits an operator with many machines and a wide swing in use on each one. The platform reports consumption by country and port and flags unusual use.
4. ISPS, a quay that does not stop, and a schedule that stays private
- Around the clock: A terminal does not close at night. The SIM can switch among operators when one network goes quiet.
- A quay is a hard place: Equipment needs a wide temperature range and resistance to shock. SimtoLink SIMs use industrial-grade chips.
- Terminals in many countries: A machine has to change networks on its own. Pricing is the same across those countries, and the bill is itemized.
- Port data: Schedules and slots are commercially sensitive. Send them on a private APN with TLS, in line with ISPS.
5. What changes for a terminal in another country
Coverage spans 200+ countries and regions and 600+ operators. A shared data pool absorbs many machines and the swing in use between them. Activation and the fleet sit in one SimtoLink console. The SIM is built for a wide temperature range and for shock, which is the environment a quay actually is.
6. Before the first crane is cut over
Count machines, countries, monthly data, and how the equipment joins the TOS and EDI. From that, choose a single SIM or a shared pool, and pay-as-you-go or a monthly bundle. Test at the terminal you will actually use, including 4G and 5G coverage and latency. Activate SIMs, set the APN, and bind devices in bulk on the SimtoLink platform. After go-live, alert on data use and inspect on a schedule. A sensible target is round-trip latency under 200 ms and availability above 99.5%.
SimtoLink already supplies cross-border port operators, shipping lines, and port-technology firms. If you are connecting quay and yard equipment abroad, contact SimtoLink for a plan built around those terminals.
