IoT SIM Cards
SIMs on China Mobile, China Unicom, and China Telecom, on the 2G, 3G, 4G, or 5G band the module already supports.
Learn moreSimtoLink connects devices with IoT SIM cards in China and abroad, and carries a project from the connection through to the data.
IoT SIM cards for China and abroad, the hardware on site, and the cloud software that reads the data.
SIMs on China Mobile, China Unicom, and China Telecom, on the 2G, 3G, 4G, or 5G band the module already supports.

Learn moreField deployments for cities, fire protection, EV charging, cold chain, security, and new energy — more than 38 industries — with an industry knowledge base behind them.
Learn moreFirst split the choice by whether the device will leave China, then check the module standard, the signal at the install site, and how the data will be used.
For devices that stay online inside China. The SIM runs on China Mobile, China Unicom, or China Telecom, and the standard, from 2G through 5G, has to be one the module already supports. If the device will stay in China, see the products under IoT SIM cards.
For devices that leave China, or that are installed outside China from the start. As described in the product pages on this site, coverage spans more than 200 countries and regions. The SIM has to attach at the destination and handle roaming between countries. Start from international IoT SIM cards.
Read which network standards the module can actually open, then check whether a matching base station is near the install site. For basements, metal cabinets, and remote sites, go by the signal measured on site. The plan name only states the tariff.
With few SIMs and steady usage, use a per-SIM plan. When many SIMs run together, check whether they can join a data pool. If the route crosses a border, choose a SIM that includes international roaming.
An engineering team and deployments that are already in the field, so the project does not start from a blank design.
End-to-end encryption for data in transit and at rest, aligned with widely used security standards.
A cloud-native platform that takes large device fleets and grows with the deployment.
Built-in models read device data as it arrives and raise alerts when a decision is needed.
Standard products that install and integrate on an existing site, so the project cycle stays short.
