There are shielding devices in the examination room. Can I receive short messages with Bluetooth on?

There is a shielding device in the examination room, and the mobile phone Bluetooth is on, so you can't receive short messages.

Bluetooth can transmit files, pictures and other things, but receiving short messages still depends on the signals sent by mobile phones. Now that there is a shielding device, it will naturally shield the mobile phone signal, resulting in the failure to receive short messages.

The shielding body scans the low-end frequency of the forward channel to the high-end frequency at a certain speed during operation. This scanning speed will cause garbled interference to the message signal received by the mobile phone, and the mobile phone can't detect the normal data sent by the base station, which leads to the failure of the mobile phone to establish a connection with the base station. Mobile phones are characterized by searching the Internet, no signal and no service system.
