2. If you dial the phone from the unshielded area to the shielded area, you will often walk into the shielded area for a considerable distance before the mobile phone is completely shielded. This is because once the mobile phone is dialed, the mobile phone itself is anti-interference Ability, this kind of anti-interference will make the mobile phone adjust the transmitting power to ensure the normal call this time. Therefore, it is generally not recommended to perform dynamic testing in the call state, but to perform static testing at various points.

3. If you dial the phone from the unshielded area to the shielded area, you will often walk into the shielded area for a considerable distance before the phone is completely shielded. This is because once the phone is unplugged, the phone itself has anti-interference Ability, this kind of anti-interference will make the mobile phone adjust its transmitting power to ensure the normal call this time.

You can try to dial a local toll-free number or a fixed landline number. If the call fails, it will be judged to be still in the shielding range. Otherwise, the shielding range is out of range.

The above are the steps and methods to test the distance of the mobile mega cell phone 5g gsm jammers. You must try several times, it is easy to find the shielding distance.
