CDMA GSM 3G Cell Phone Signals Jamming Device
Oh, we were getting about 10 junk calls per day in this busy Washington D.C. Metro area. We are about to ditch our landline because I was so tired of it. Decided to try this device and the junk calls have remarkedly decreased about 95%. Our phone is eerily silent; however the real calls are getting through. I just programmed the cell phone jammer as instructed which was very simple to do and it sure seems to be catching the calls. The rare junk call that gets through is using the local area code as a spoof which is the latest thing to make you pick up, but then I can just press the button and block the number. It is amazing so far how many calls are being blocked....it is a big help and makes for a much quieter house...
2G 3G 4G Signal Jammer Handhled Portable E06
This cell phone jammer really does a great job. Easy to use. Blocks all kinds of calls. well worth the money. I bought 1 of these for myself , was very pleased with how it works , I reordered 1 for a friend . unlike Panasonic phones which claim to block calls , but don't .. they only block 30 #'s . & they let your phone ring once then hangs up on the caller. the caller thinks he reached you , but you just hung up . plus robo calls know they reached a live # once your phone rings , they keep calling you over & over...making matters worst cas , the robo caller will keep trying different times of day & night to see when you will answer . it keeps track of how many times each ph. # tries to call you .. blocks large groups of #'s such as no name , no number , robo calls , international ,blocked #'s ,so easy to use . you don't have to be home to block #'s . you can review #'s when you get home then block them . if you block someone by mistake , you can easily unblock them...
Mini Portable E06 GSM 3G 4G WiFi Signal Blocker
This is the best purchase I have made since I replaced my SUV with a Pickup!!! We received unwanted calls almost every day some starting at 6AM. Since use this cell phone jammer, my telephone rings only for the calls we want. The others have disappeared entirely. I finally have complete control of my telephone. Where has this been all my life? I spend my days training and riding horses. Prior to this purchase, when I return home in the evening, I would look at all the calls that would have disturbed me and erase them...
8 Bands Strong Heat Dissipation GPS WiFi Signal Blocker
This thing has been nothing short of amazing! We got this cell phone jammer about 3 weeks ago and installed it right away. Install was VERY easy! We have our TV, internet and phone through Comcast, so we hooked up the call blocker by going from the modem, to the call blocker, then to the phone. We haven't had any issues with our caller ID or calls from blocked numbers ringing once before being blocked. In the almost 3 weeks since installation, we went from 5+ annoying calls per day to virtually zero. I work at home and it's supremely annoying when the phone rings while I'm in the middle of something. It's especially annoying when it's one of those "survey" calls. I find that I'm much more productive and a lot less aggravated...
16 Bands Powerful Desktop Jamming Device
So far the cell phone jammer is working great. Once the call blocker was set up Incoming nuisance calls immediately declined by about two thirds. Apparently the 5K prerecorded blocked numbers that come with the Call Blocker did that job. Usually I would get 4 telemarketing calls on Monday mornings by noon. None were received the first Monday after installation of the Call Blocker. Those were calls I could not block with the call blocker that came with my landline set. This block works great for all the calls requesting political contributions with no number showing. Also included with the Blocker was an app to block calls on my cell if needed. The fact that the phone doesn't ring at all with this blocker is a blessing. So far the jamming device is my new best friend...

Makes a great birthday gift...
Military 6 Bands Hidden Type WiFi GPS Jammer
live with and care for two disabled elderly relatives who were being absolutely bombarded with robocalls, scammers and telemarketers. At the very least five or more calls, 7 a.m. to 10 p.m. seven days a week. We never were actually scammed but the constant interruptions were causing chaos. I tried blocking with our handsets but they just weren't robust enough to stop the problem. Exasperated, I found this cell phone jammer and gave it a shot. Some here are saying that it doesn't seem to work well with U.S. phone systems but I haven't found that to be the case in our situation...
6 Bands Military Hidden Handheld GPS WiFi Jammer
I have been averaging at least four unwanted calls each day. Telling these people that your number is on the National Do Not Call List does not stop them. I did not want to change my telephone number and pay to have it unlisted. I read about the cell phone jammer online, and I decided to buy it. Set up took about three minutes. I then tested it out by using my cell phone to call myself. I blocked my cell number. The jamming device worked. My land line did not even ring. In fact, I have not received a single unwanted call since I hooked it up to my phone line. If you are fed up with telephone solicitors, buy the device...
2018 Most Popular Handheld Signal Jammer
We were having a very bad week with robocalls and had to unplug our phone for peace. I had reviewed several call blockers but the cell phone jammer seemed to be the best product for what I was looking for. It took less than a minute to connect it, and less than an hour for the robocalls to restart. Stopping the calls was as simple as pressing a button. We finally have peace and quite and the only calls that rings are the numbers that we have elected previously and stored. It does not interfere with any of our programed number we have stored. If you are tired of robocalls, I highly recommend this product to help restore order to your phone system. Get it, you will not be disappointed...
Top Sale 2019 Mobile GPS WiFi Signal Jammer
Thus far this cell phone jammer is working very well. While researching the product I happened across a YouTube video which evaluated the item and said that when connected via the standard setup it wouldn't allow the caller ID on his cordless phone to receive the names of those calling him (instead only the telephone numbers appeared on the handheld phone. If that would've been the case, it wouldn't have worked for me and I would've moved on. Instead I posted a question here on Perfectjammer about this supposed issue and was told that it DID in fact allow both the caller's name and number to appear on the handheld phone...
Cell Phone GPS WiFi Signal Blocker Powerful
I bought this product to try because I get 2-8 (!!!) per day. Morning to night I get robo-calls, "unavailable" number, silence, I even get calls showing my own number. This was becoming intolerable so when I first saw the cell phone jammer online I decided to try it. Simple is the only way to describe it. Take the unit and plug the short (8 inches or so) phone cable (included) from the CPR to your portable home phone base, base to line (as normal...) and robo-calls go away! Annoying robo-calls have dropped dramatically to sometimes one or NONE a day. I LOVE IT!!! BUY ONE OF THESE CALL BLOCKERS - KEEP YOUR SANITY! Recommended highly...
Large Jamming Ranger GPS Lojack Jammers Reviews
After several years of telemarketers calling we finally decided to invest in a call blocking device. We selected this cell phone jammer. We have had it for several weeks. We had an initial problem with calls going to our Verizon voice mail vs the voice mail on our home phone unit. A call the tech services at CPR recommended we reduce the number of rings before the voice mail kicks in. We did that and it solved the problem. The unit has blocked untold numbers of telemarketers and our house is not much more peaceful. This device is easy to use, install and is works...
18W GPS WiFi Blocker
I get dozens of robo calls and solicitations daily, even though I am on the Do Not Call Registry. I recently put my grandson down for a nap at noon and got seven annoying phone calls in the next 75 minutes until he woke up from the calls. I then ordered the cell phone jammer and when it arrived, I blocked all the toll free numbers that I knew as well as the "unavailable" and "out of area" calls. Like magic, I was no longer bothered by annoying phone calls...
A12 Super Powerful GPS WiFi 30W Signal Blocker
WOW! This is an awesome cell phone jammer. Before I ordered this product, I was receiving at least twenty robocalls per day. The scammers were holding my landline (and me) hostage! How annoying is that?! I had to either ditch my landline or try some other method. When I found this product and read the many positive reviews, I decided to give it a try. Setup was a snap, instructions were clear and concise. Immediately upon installation, my robocalls began to dwindle. I love the features that block "unavailable" and "out of area" calls, in addition to being able to block calls in any specific area code. The product is worth every penny. Thanks to the...
Comments Of Powerful Cell Phone Blockers
When I ordered it I didn't really expect it to work. I was wrong. The cell phone jammer does pretty much exactly what it sets out to do: it intercepts incoming calls and blocks unwanted numbers by adding them to the internal database of blocked callers...
A12 30W Super GPS WiFi Lojack 3G 4G 5.8G Jammer
WOW! What a wonderful boon to human kind. I was getting 3-5 telemarketing calls per day, many of them robocalls.

The 5000 blocked numbers it has built in clearly do most of the trick...

I installed the call blocker in series ahead of my AT&T phone per manufacturer instructions...
E10 Military Powerful Mobile Phone GPS Blocking Device Reviews
Best cell phone jammer EVER! I purchased this one to replace the one I already had (different brand). It quickly filled up with blocked numbers and I couldn't add anymore. It was ineffective at blocking 'out of area,' private, and 'unavailable' calls. Also, the phone would have to ring once before the call was blocked...

As a night time caregiver for my 98 year old mother, my morning sleep is the only thing that keeps me physically able to go on. I thank God that I found the cell phone jammer Call Blocker on Amazon and bought it.

Ishida is especially knowledgeable and coached me through everything I needed...
