First, determine what is your purpose of jamming the cell phone signals. If you are tired of phone noises in the theatre, café, library or other public areas, a portable cell jammer suits you best. You can carry it around and turn it on without being noticed, the blabbermouths will shut up within seconds. Concerned with the safety in the petrol station or prison, you'd better choose a high-power explosion-proof cell jammer. The antennas enable the users to attune for the blocking range according to specific circumstances. The remote control allows the cell jammer only accessible to the authorized personnel. The explosion-proof nature prevents the jammer from being destroyed by the ill or illegal elements. If you are paranoid of being tracked via cell phones, a cell jammer blocking both the phone signal and the GPS signal makes you satisfied, for most of the tracking devices rely on the GPS system. The two-in-one cell jammer dismisses the spy who wants to know your exact location and steal your business information.
Second, make sure of the frequency range in your area. Generally speaking, there are two versions of cell phone jammers: One for Europe, North Africa and the Gulf States GSM networks (900 & 1800), and one for America and Canada which ranges the frequency between 800 and 1900 MHZ. Make sure that you get the right version for your location.
Thirdly, take the price into consideration. If you are not sure which one to buy for your conditions, follow the golden rule that the best product costs more. The expensive cell jammer covers a much larger blocking range than the cheap one. It is more efficient in blocking the cell phone signals. You know, it accounts when the cell jammer helps to create a temporary dead zone in your area.
Fourthly, pay attention to the after-sale service of the cell jammer. The trustworthy company guarantees a free trial period. If you are not satisfied with the product, you can return the product and get your money back. And your complaint will be dealt with in a careful way and even get compensated.
