1. Scenario Overview
Operator integration is the engineering work: how the connection to the IoT SIM management APIs of China Mobile, China Unicom, and China Telecom is built. Multi-operator management is the operations view. This page is the API, the protocol adaptation, the data sync, and the security rules. Your systems call one interface. The platform talks to the three operator systems and covers activation, suspend and resume, plan changes, and usage queries.
SimtoLink is already connected to the three major operators and works to each operator's specification and process. A standard wrapper hides those differences, so you integrate one API. When that is done, multi-operator management can run the three networks as one operation.
2. Core capabilities
One REST API over three protocols
China Mobile, China Unicom, and China Telecom APIs are wrapped as one RESTful API. You call that API. The platform routes to the right operator. Activation, suspend and resume, plan changes, usage queries, and usage sync are included. Protocol differences stay underneath.
Data sync
SIM status, usage, and plan details stay aligned with the operator. Sync can run on a schedule or only for what changed, at minute-level frequency, so the figures the business uses match the operator.
Batch commands
Activation, suspend and resume, and plan changes can be sent as a batch. A large job is split and rate-limited so the operator API is not flooded. Results come back on an async callback, and you can ask for progress. Tens of thousands of SIMs do not block the console.
Security the operators require
Each operator's connection rules are covered: certificate authentication, an IP allowlist, and encrypted transport. Data in transit and at rest follows those security specifications.
3. How a connection is stood up
4. Integration beside multi-operator management
The two complete each other. The split is:
| Dimension | Operator system integration | Multi-operator management |
|---|---|---|
| The question | How the capability gets connected | How the SIMs are run once they are connected |
| What it does | Connect the API, adapt the protocol, sync the data | One list, batches across networks, reports across networks |
| Why a team wants it | Operator capabilities are reachable, and the data matches | Three networks from one screen, with less daily overhead |
| What has to exist first | It is built on its own, and unified management sits on it | It turns on only after the connection is finished |
Do them in that order. Finish the operator connection, then turn on multi-operator management, so the path runs from a live API to daily operations.
5. Where teams use it
- Three networks from one integration: China Mobile, China Unicom, and China Telecom are reached without three separate builds.
- Sync measured in minutes: SIM status and usage stay aligned with the operator, so the business figures and the operator figures do not drift.
- Commands in a batch: Activation, suspend and resume, and plan changes go out together. Tens of thousands do not block the console. A callback and a progress query are both available.
6. What one connection changes
You skip the cost of building and operating three separate connections. One integration reaches all three networks. A standard wrapper keeps operator differences out of your code. Sync keeps the business figures honest. Security controls match what each operator asks for. With multi-operator management, the path continues from the technical connection into daily operations.
7. How to put it in place
Connect one operator and prove the flow, then add the others. Certificates and the IP allowlist have to be ready before the security review, because each operator sets its own bar. Sync can be scheduled or incremental, so status and usage stay aligned. When the connection is live, turn on multi-operator management.
