There are two standard options for SDP03HD: One model interferes with the 2G GPS signal and the other model interferes with the 2G 3G signal. You may think that 4G is now in use in many places and that 5G is coming to more and more areas, but in reality many areas of Europe and even the world are still using 2G and 3G signals. The main reason for this is that many areas have a small population and the construction of 4G and 5G base stations is not economically viable. Therefore, 2G and 3G jammers are still very important tools.
For example, in many areas, older people in care homes can only use cell phones with 2G or 3G signals to make calls. Of course, there will be other signals in care homes, such as 4G and Wi-Fi signals, because the staff caring for the elderly will need to use them. This is just one example I have given to illustrate that this 2G-3G jammer can handle 2G-3G signals in a care home. Each device has its own suitable usage scenario.
You can also choose a different model of this jammer, namely the 2G GPS signal jammer. You can use this 2G GPS jammer to jam GPS signals. Jammers like SDP06HD and SDP10HD and others can also help you to jam GPS signals. Of course, the price of jammers with more frequency bands is also higher. I think the device that suits you is the best device. This 3-band jammer can also be used in other scenarios. I will not list them one by one here. I think you will know if you want to buy it.

Signals disturbed by the product:
GSM: 925 - 960 MHz
3G: 2110 - 2170 MHz,
GPS L1L2L3L4L5: 1170 - 1580 MHz
Features of the product SDP03HD:
- If you need to jam GPS signals, I recommend SDP03HD, which effectively blocks GPS satellite signals and protects your privacy and confidential information.
- I would like to tell you that GPS signals include L1L2L3L4L5, SDP03HD interferes with all current GPS satellite positioning signals.
- If you want to disrupt the 2G-3G or 2G-GPS signal and still make phone calls, the SDP03HD is the perfect device for you as it does not interfere with the normal operation of cell phones or other electronic devices.

Frequently asked questions
Do I buy a portable or a desktop device?
Our portable jammers have built-in batteries that can be used and charged continuously. However, if your application requires continuous use at a fixed location and not intermittent use (24-hour use without interruption), a permanently installed desktop signal jammer is the better choice.
[Note] Portable jammers can also be used for a long period of time without interruption, but the heat dissipation performance of desktop devices is better. Usually, expensive portable devices have more heat dissipation components than cheaper devices. You can understand that for the same price, the advantage of portable jammers is the built-in battery and the advantage of desktop jammers is the better heat dissipation performance. There are differences between different devices. You can first understand it from my analysis above. If you want to know more about the product, you can also contact us.
Does STORSENDERPRO also ship during the holidays?
STORSENDERPRO normally ships on working days, excluding weekends and public holidays. At the same time, employees of logistics companies and express service providers also work on weekdays and do not collect goods on weekends and public holidays.
Will the jammer I buy interfere with the signal in my area?
We adjust the interference frequency band of the device according to the delivery address specified by the customer when ordering. There are differences in the frequency bands of interfering signals between the United States and Europe. More specifically, the signal standards may be different in different regions. For example, the signal standards in Europe and the United States differ in certain frequency bands. Europe has its own signal standards, the U.S. has its own signal standards, and other regions have signal standards. We can adapt them all. So don't worry, as long as the region where you use the device and the delivery address in the order match, there will be no problem.
If customers wish to jam signal frequency bands in other regions, please note this clearly when ordering or let us know via the official e-mail ( info@storsenderpro.com ) with. We will then manufacture the devices according to the customer's requirements.
Can low-power jammers interfere with devices with high-power signals?
To answer your question, I have to give an example. You can think of it this way, the signal strength emitted by the high power signal device itself is 10, but as the signal transmission increases in distance, 10 starts to decrease to 9, 8, 7 or even 3. If you are not close to the signal source and the signal you need to jam is level 3, for example, your jammer must be able to emit jamming signals that cover level 3. If your jammer can only jam level 2 signals, level 3 signals will only be weakened but will still be present. If you transmit level 4 jamming signals, you can block level 3 signals directly. The numbers above are just examples I have given and do not represent anything else. It merely serves to make it easier for everyone to understand the operating principle of the devices I have analyzed.
So from my analysis above, you can deduce that low power jammers can interfere with high power signal devices because the high power signal is at some distance from you and the signal strength of the high power signal source is not as strong when it reaches your environment. You can therefore use low power jammers to interfere with devices with high power signals. However, the closer you get to the high-power signal device, the lower the interference effect will be.
If you need to jam high-power signaling devices, you still need to buy a high-power jammer.
Under normal circumstances, the above analysis need not be so complicated. In fact, normal GPS signals, Wi-Fi signals and cell phone signals are not strong. Unless you happen to be near a base station, you don't need to worry much about this as the signal strength is stronger around the base station. If you are only in a normal area, most of our jammers will meet your requirements.
Most of our jammers are suitable for most environments.
What should you pay particular attention to when using a jammer?
When using a jammer, you must pay particular attention to the correct connection of the antenna and the antenna hole. Each antenna is numbered and the antenna holes are also numbered. Make sure that the antenna numbers and the antenna hole numbers correspond. If the numbers do not match, the jammer will most likely not work.
