Does not work on 4G signals and effective radius is 7-9 meters
In India, following 4G frequencies are in use as of now (April 2019) Band 40, Band3 and Band5.This devices blocks Band 40, but does NOT work for other 2 bands - Band 3 and Band 5.Also the effective radius is 7-9 meters.If you are looking for jammer only for 2G and 3G, this device is ok.However if you are looking for a jammer for 'all available frequencies in India', this is NOT a good choice.In fact, I observed that most of the jammers available for online purchase have similar issue.Most likely these are old devices (at least few years old, when 4G was not used) OR these are NOT designed for Indian mobile frequencies.My advice for online purchase of mobile signal jammer is -(a) Confirm with vendor whether device is designed for all mobile signal frequencies in your country, and the effective radius is as per your requirements(b) Confirm that 'return policy' is available with the device you select(c) Have a 4G mobile phone with Jio SIM card available, before ordering the device. Jio uses all 3 frequency bands with automatic switching, hence is perfect for testing.(d) On the 4G mobile phone with Jio SIM, try selecting network 'manually'. This will list all available signals - 2G, 3G and 4G(e) When device is received, check with Jio SIM. Power on the device, take mobile phone away from the device (to maximum distance you need the device to be effective). Search available mobile networks, though 'manual network selection'. If device is working ok, there will be NO mobile networks listed. If any network is listed, it indicates that device is not working on all frequencies.(f) Repeat the test at 2-3 different locations(g) If you observe any problem (if any of the network signals is not blocked), return the device to the vendor.
