Reviews of all GSM jammers

GSM is the most commonly used frequency range for disruptive cell phone networks and mobile communications. It includes four main frequency bands (850 MHz, 900 MHz, 1800 MHz, 1900 MHz) and many smaller standards used in different countries/regions in the world (such as UMTS, CDMA2000, Nextel, TDMA, AMPS, W-CDMA PCS, etc.) . Under the communication standard, 3G must be mentioned separately, because it is not only a modern communication frequency, but also can be used for other purposes. You can choose GSM or 3G frequency to block gsm.

It works! However, it gets extremely HOT to the point that if you touch it, you BURN your hand. Due to the excessive heat, the device inflated - but it still works well. It is used 5 days a week for at least 8 hours a day. I haven't had any problems so far!

It works just like advertising. If the distance is large enough, BT will also be eliminated. The sales force and technical support are really great. Don't let the lack of purchase options affect you. They ship the fastest, fastest I've ever seen. The product comes with a very nice box, a magnetic lid and first-class packaging. It has a very good structure and is obviously something to be proud of. They are honest people and offer honest products at reasonable prices.
