What should I do if the signal jammer does not work properly? from dojammer's blog

In order to facilitate customers to use signal jammers, this article will summarize some possible reasons why the signal jammer you purchased does not work properly.

1. You must buy the right jammer according to your needs, which is more important!

(1) If you want to block mobile Internet access, you must choose a 2G3G4G5G full-frequency signal jammer. At this time, you must consider whether to add additional functions such as GPS (navigation positioning) or WIFI (wireless access)!

(2) Choose a suitable power supply: portable jammers have low power and are easy to heat up, while desktop all-in-one jammers have high power and good heat dissipation! The shielding range of desktop all-in-one jammers is farther!

(3) If you want to block GPS tracks, you need to choose a two-in-one jammer (cheap 2GGPS jammer) at least! Because when you only use a mini GPS jammer to block GPS, it will automatically activate GPRSGSM positioning through the embedded SIM card.

2. After receiving the portable jammer with a battery (desktop all-in-one jammer without battery), it must be fully charged within 6-10 hours;

3. All antennas must be installed according to the label (1-12-23-34-45-56-67-78-8 or GSM to GSMGPS to GPS.......). More importantly, do not turn on the jammer without installing the antenna!

4. Affected range: location reception sensitivity <=-75dBm. The affected distance will vary according to the reception sensitivity and location. If you are close to the signal base station, the actual effect of the jammer will be very poor!
