Cloud-based SIM cards provide connectivity to devices and terminals.

Abstract

This invention belongs to the field of communication technology, and mainly provides a cloud SIM card providing device and a terminal networking device. It obtains a cloud SIM card allocated by a cloud server through a communication module and places the cloud SIM card in a cloud SIM card placement module, enabling the terminal networking device to read the cloud SIM card information and register for internet access via the cloud SIM card. The cloud SIM card providing device of this invention also includes a power management module comprising a power regulation module and a battery, enabling it to draw power from the SIM card interface of the terminal networking device. This eliminates the need for external power supply and user charging, allowing for long-term stable operation and reducing user maintenance. Furthermore, the SIM card interface of the terminal networking device will not experience overload and power failure due to the high current of the communication module. Moreover, the cloud SIM card providing device of this invention is compatible with terminal networking devices of different interface types, exhibiting wider applicability and stronger compatibility.
