I recently bought a mobile IoT card. Would you like to know if a wifi signal jammer can block the mobile IoT card?

Will do. The current wifi jammer is full-band, they can block all 2G 3G 4G signals, 2.4G WIFI signals, and Bluetooth signals under the three operators of China Mobile, China Unicom, and China Telecom, no matter what kind of mobile phone card you use, will be blocked. It uses its own frequency to interfere with the frequency sent by the mobile phone receiving base station and wireless router, so as to achieve the purpose of shielding them.
