1. What a logistics device sends over cellular
Smart logistics is the digital supply chain in one place: the warehouse (WMS, warehouse management system), transport (TMS, transport management system), delivery dispatch, and supply-chain visibility. Logistics tracking is about seeing the waybill. Smart logistics is about keeping the whole chain online: warehouse gear such as AGVs, picking PDAs, and sortation lines, plus delivery terminals and in-vehicle terminals, so stock, waybills, and in-transit data stay in sync. Warehouses often have weak Wi-Fi, or wireless is hard to install, and cellular keeps AGVs and handhelds steady. SimtoLink supplies 4G and NB-IoT to logistics companies, with a data pool and an API into the WMS, TMS, and ERP.
2. Warehouse, road, last mile, and the border
The chain covers the warehouse, the road, delivery, and cross-border freight. Bandwidth, and how quickly a status has to land, differ by stage:
Warehouse and WMS
AGVs, picking terminals, and handheld PDAs talk to the WMS over 4G, for inbound, outbound, stocktakes, and stock sync. Warehouse Wi-Fi is often weak, and cellular keeps the link steady.
Transport and TMS
In-vehicle terminals and the driver app report location and waybill status, for TMS dispatch and electronic waybills. The logistics-tracking and asset-tracking use cases go further on the shipment itself.
Delivery and the last mile
A courier’s handheld and the delivery vehicle report proof of delivery and exceptions over 4G, for dispatch and customer lookup. Typical use is 100–300MB a month.
Cross-border and the supply chain
Cross-border freight needs a network in more than one country. SimtoLink international IoT SIMs cover 200+ countries. Supply-chain visibility needs the WMS, TMS, and ERP data in one place.
3. What the logistics link has to cover
- Weak signal and many devices: Warehouses often have weak Wi-Fi, and metal racks block it. Cellular keeps AGVs, picking PDAs, and sortation lines steady. With many devices online at once, data has to be shared out sensibly.
- Coverage on the road: Trucks and couriers cross regions, so more than one operator has to fill the map. Cross-border freight needs an international IoT SIM or eUICC.
- Stay up, then catch up: Waybill status and stock sync cannot drop. Cache locally and upload the gap after the link returns, so the WMS and TMS still agree.
- Security and compliance: Waybills and supply-chain data are commercial secrets. Sessions need TLS, a private APN or a VPDN, and an IP allowlist.
- A flexible API: Connect to the WMS, TMS, ERP, and the e-commerce hub, so inbound, outbound, dispatch, and supply-chain visibility close the loop.
4. Which SIM fits which stage
Bandwidth and latency differ by stage, so the SIM follows the job. Use the table as a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Warehouse AGVs and picking PDAs | 4G | WMS link, live stock, and a weak-signal floor |
| Trucks and in-vehicle terminals | 4G | TMS link, track reports, and electronic waybills |
| Courier handhelds | 4G | Proof of delivery, customer lookup, and a link on the move |
| Cross-border freight | International SIM | Coverage in many countries, eUICC, and a link that stays up |
5. How much data a logistics device uses
One device typically uses about 100–500MB a month. Warehouse and delivery terminals are about 100–300MB, and more if they carry video. Pool SIMs by stage and keep 20%–30% spare.
6. Security for waybills and the chain
Waybills and supply-chain data are sensitive, so treat the link as high security. Sessions need TLS, a private APN, and an IP allowlist. SimtoLink provides the private APN, a VPDN, and real-name registration for the SIMs.
7. What SimtoLink would put on the chain
For trucks, delivery terminals, and warehouse equipment, use a 4G IoT SIM. The chain has to report waybill status and location as they change, and several stages are online at once. SimtoLink plans for 99.9% network availability, a choice of operators, a data pool, and an API into the WMS and TMS.
8. Taking a network live
Take a logistics rollout through these stages:
Pick the SIM by stage—warehouse, transport, or delivery—and check coverage in the target area. Set the APN and IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first site through the wider network. Contact us for a plan built around those lanes.
