I would like to purchase a signal jammer capable of jamming all telephone communications

Hello,

I am contacting you to ask for advice.

I would like to purchase a signal jammer capable of jamming all telephone communications, but without disturbing the WIFI connection.

I am not looking for a device that would act over a very large area, but a jammer that would act between 5 and 10 metres would be suitable, I think.

This device would be intended for use in France, so it must be compatible with the telephone networks in that country.

In your opinion, is it important to jam 2G/3G/4G/5G? Or is 5G still superfluous in France?

Would you have a particular model to recommend to me? Because I admit I’m a bit lost in the choice of devices.

Also, if I make an order on the website, could you tell me where the package will be shipped from? I would not like to have any problems with customs frontier…

Thank you in advance for your help.

Bests regards.
