1. What a shared parcel locker asks of the SIM
A shared parcel locker covers parcel stations, smart pickup, and compartment control. Over 4G it sends drop-off, pickup, status, and video. A compartment is the individual cell that holds one parcel, and it has to report whether it is occupied. The station joins courier platforms such as Cainiao, Fengchao, and Kuaidi 100 for order sync, status back, and settlement. SimtoLink gives locker operators 4G, a shared data pool, VPDN, and an API into the courier system.
2. Drop-off, pickup, and the compartment
A shared parcel locker covers drop-off, pickup, and compartments. Bandwidth and how live the door has to open are not the same in each:
Drop-off and compartment control
A courier scans over 4G to open a compartment and report the drop-off, with compartment assignment, a full-cabinet alert, and drop-off counts.
Smart pickup and notices
The customer picks up with a QR code or a pickup code. The cabinet checks it over 4G and reports the pickup, with a pickup notice and an overdue reminder.
Courier-system handoff
The cabinet joins the courier platform over 4G for order sync, status back, and settlement.
Video and maintenance
Cabinet video comes back over 4G for security monitoring, evidence in a dispute, and remote maintenance.
3. What the locker link has to guarantee
- Live drop-off and pickup: A courier scan that opens a compartment, and a pickup code, both need low latency. A full-cabinet alert and a pickup notice have to go out as they happen.
- Courier platforms: Cainiao, Fengchao, and Kuaidi 100 need a stable link for order sync, status back, and settlement.
- Compartment status: Occupancy and the drop-off and pickup record have to come up as they change, with a full-cabinet alert and an overdue reminder.
- Video and security: Cabinet video supports security monitoring and evidence in a dispute. A VPDN is optional when the data has to stay private.
- Scattered sites: Residential compounds, office buildings, and stations often have no cable. 4G is the coverage. Pool by device type to hold the cost down.
4. Which SIM fits which cabinet
Bandwidth and how live the door has to open differ by device and by the job. Site count and the security bar both belong in the choice. Use the table as a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Cabinet controller and compartments | 4G | Drop-off, pickup, status, platform handoff |
| Cameras and video monitoring | 4G | Security monitoring, evidence in a dispute, mid-range bandwidth |
| Stations and several courier brands | 4G | Order sync, settlement, VPDN optional |
5. How much data a cabinet uses
One device typically uses about 50-200MB a month, more when video monitoring is on. Pool by device type and leave 20%-30% spare.
6. Security around the cabinet
Treat this deployment as medium security. It needs a VPDN, TLS, and an IP allowlist. SimtoLink supplies the VPDN and a private APN, and completes real-name registration in one process.
7. What SimtoLink would put on the cabinet
For a shared parcel locker, use 4G IoT SIMs on the cabinet controller, the camera, and the display. The cabinet has to report pickup status as it happens, carry video monitoring and ad push, and sit in many residential compounds and office buildings. Plan on 99.9% network availability, a shared data pool, and an API into the courier and station management system.
8. Putting the first cabinets on the street
Take a locker rollout through these stages:
Choose by device type. Check coverage at the site. Set a VPDN or APN, an allowlist, and an alert at 80% of the data allowance. SimtoLink stays from the first cabinet through support. Contact us for a SIM plan sized to that locker estate.
