Can I use mobile wifi where the signal and network are blocked?

At present, mobile phone signal shielding is full-band, which can shield all 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals of China Mobile, China Unicom and China Telecom. Its principle is to interfere the mobile phone to receive the frequency sent by the base station and wireless router through its own frequency, so as to achieve the purpose of shielding.

Therefore, as long as it is 2.4G WIFI, it will definitely be blocked. Unless it is 5.8G WIFI, the frequency of 5.8G is not blocked as standard. At this time, you can use the mobile phone WIFI. However, if the frequency of 5.8G is added to the mobile phone signal shielding, then the mobile phone WIFI will not work.
