FAQ
What is an IoT SIM card?
An IoT SIM card is a type of SIM designed for smart terminals to enable device-to-device data transmission and remote communication. Unlike regular SIM cards, IoT SIMs are commonly used in industrial equipment, remote monitoring systems, vehicle telematics, smart metering, POS terminals, and wearables. They offer greater connection stability, lifecycle management, and scalability for massive deployments.
How is an IoT SIM different from a regular SIM card?
An IoT SIM is optimized for machine-to-machine (M2M) communication, enabling long-term stable connectivity, infrequent device changes, remote SIM management in bulk, and low-power operations. Regular SIM cards are designed for consumer smartphones and are not suitable for industrial or large-scale applications.
What types of devices are compatible with IoT SIM cards?
IoT SIM cards are compatible with a wide range of devices such as smart meters, GPS trackers, industrial gateways, smart street lights, vehicle terminals, agricultural sensors, shared mobility devices (like bikes or power banks), drones, and more.
Do IoT SIM cards support international roaming? Which countries are covered?
Yes. Our IoT SIM cards support international roaming with multi-network auto-switching, covering over 180 countries and regions, including Europe, Southeast Asia, the Middle East, Africa, and Latin America. Multi-operator access ensures stable connectivity across borders.
How do I activate and manage an IoT SIM card?
We offer a web-based management platform and API interface for activation, remote SIM control (enable/disable), device status monitoring, traffic alert configuration, and auto-renewal setup. Bulk operations are supported. Some SIMs are pre-activated and ready to use upon installation.
How is billing handled? What plans are available?
We provide flexible billing options including monthly, yearly, per-data package, shared pool, multi-card management, and global roaming packages. Entry-level plans start from just a few MB per month for low-frequency devices, and custom plans are available for high-volume usage.
Can I use the IoT SIM in mobile hotspots, smartphones, or routers?
Technically yes, but it’s not recommended. IoT SIMs are designed for device communication and usually do not support voice or SMS. They’re not suited for high-bandwidth applications like video or gaming. Using them in consumer devices may result in throttling or service suspension.
What should I do if the device cannot connect to the network?
First, check if the SIM is properly inserted, ensure the device supports the required frequency bands and network type, and verify that the device is within coverage. You can also check the SIM status on our platform. If the issue persists, contact technical support for diagnostics.
Can I switch devices or update binding info for the SIM card?
Yes. The SIM can be switched between compatible devices, and you can update the binding info (IMEI, SN, ICCID) via the backend system. Note that some countries or operators may impose limits on card changes or reactivation frequency.
Do you offer test SIM cards or free trials?
Yes, we offer 3 test SIM cards with 7 to 15 days of free trial to help clients evaluate network performance, device compatibility, and platform functionality. This is ideal for pilot testing or pre-purchase validation.
