  1. These cell phone jammers are available at a very reasonable price. You can buy this cell phone jammer very easily. As this service takes nominal charges on the network, so you would need to spend a little amount to get complete peace of mind when you are not willing to get disturbed.

  2. Cell phone jammer is an interesting and helpful device when we don’t want to be bothered by the cell phone noise. I just bought myself a cell phone jammer the other day from JAMMERALL ,it is working great and BTW, it’s legal here in my country.

  3. Is there a company here in Edmonton Canada that sells these and what is the max range these Jammers can cover. What is the best battery life these have off the charger. Thanks.
