Technical Field

[0001] The utility model relates to the technical field of Internet of Things cards, and in particular to a portable Internet of Things card protection device. Background Art

[0002] IoT cards are provided by carriers to IoT service providers for connecting smart terminal devices to the internet. They are sold in bulk only to corporate users and are widely used in areas such as shared bikes, mobile payments, smart cities, and vending machines. They are not intended for individual users. IoT card operation requires a unified network. Typically, after issuing IoT cards to corporate entities, carriers create a "traffic pool" for each enterprise. The use of these cards by the enterprise consumes data from this pool. Carriers can manage, control, and even locate IoT cards through backend services. Once the data in the pool is depleted and the enterprise fails to renew its subscription, the carrier will disable the IoT card's connection to the internet through backend management.
