Usually, a lot of people buy a signal mobile phone jammer and go back and find that the actual jamming distance is much smaller than what the supplier says. Why is that? This is very simple, because the data provided by the supplier is in the best condition, and normally when we test in the city, we will get obstructed by buildings and interference from signal towers, so the interference distance will be smaller.
Most people don't want to block cell phones which are over 20 meters away from them and this is why most people prefer purchasing cheap and efficient devices which don't offer a huge working radius. I assure you that the market can offer you many products which have different characteristics and prices, so it won't be a problem to find a device which suits your budget. However, you must remember that the most important specification of any signal jammer is the frequencies that it supports – make sure that they match the frequencies used in your city. If they don't match them then this blocker won't work properly in your area.
