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...
Powerful E08 Portable Mobile GSM 3G 4G Jammer
The cell phone jammer has to be the coolest invention ever! My office, which is in Texas, has been using this device for 3 days. The robo calls have disappeared completely. Bye, bye Google. Only 4 telemarketers have gotten through in 3 days, and those were quickly blocked. My husband and I have a service business and, if we want to stay competitive, we need to answer every call. Even watching for area codes does not help cull out telemarketers since most people keep their mobile number when they move, so even a call that appears to be out of state, could be a local resident needing service. At Last, Victory is Mine!! Thank you, cell phone jammer...
E08 Powerful 8 Bands GPS WiFi 3G 4G LTE Blocker
This product is AMAZING !!! Before we bought this device we were receiving anywhere from 15 to 25 robo calls a day. It was very frustrating and we even considered cancelling our home phone. After we use this cell phone jammer we actually thought that our phone had gone dead. The silence was deafening :-) That's all there was to it. We wish that we had purchased this much sooner...
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...
8341HA-5 3G 4G Mobile GPS WiFi Handheld Jammer
I like it a lot. Having repeatedly reported robocalls to Nomorobo.com only to have the number of calls increase, I was really fed up with people I had no interest in talking to or listening to dialing my number. When I saw the cell phone jammer, I had to try it. So far, so good. When doing this, I can view the number of times a blocked call has been blocked. I can't describe the satisfaction I get when I see a number that has been blocked multiple times. As I said when I started, I really like this device a lot...
Gold Type 5 Bands Portabale GPS WiFi 4G Jammer
Since I use this cell phone jammer and learned its' little nuances it has blocked all numbers required. I had a political party from the DC area that called me constantly even though we had asked them not to. Any time I would block one number from them they would use another. It appears they had an unlimited resource of numbers from a particular area code. Since I had no relatives from there I blocked that area code and it has been quite peaceful. Oh, they still try to call as I can look at a missed call list on my phone system. I smile every time I see they've tried to reach me and it has been blissfully quiet...
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...

If you have an elderly parent the last thing you want is for them to undergo any unnecessary stress. Harassing telemarketers and misdialed numbers can be a source of stress for an elderly person for many reasons. This cell phone jammer device not only provides them with the ability to see the number calling them it also provides an easy way for them to permanently or temporarily block that number that is calling. 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...
8 Bands 3G 4G Mobile Phone Handheld Cheap Jammer
After using the cell phone jammer for over 2 months now we are as pleased as as the day we started using the product, perhaps more so. It has been very effective in blocking all types of unwanted calls. Since our jamming device is located on a floor of the house different from that where we spend most of our time, we appreciate how easy it is to block calls directly from our wireless phones. The only real issues we have noted are 1, too many people and businesses fail to properly activate their caller ID, and 2, scammers are very effective in disguising or spoofing their identity so sometimes it takes time to effectively block their calls. The other issue is how little effort our representatives in Congress are applying to eliminating ROBO callers. You can help by lending your voice to the Consumer Report effect in this area. Also, do not answer any call unless you know FOR SURE who the caller is...
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...

This is my second cell phone jammer. My first one got hit and smoked by lightning during one of our infamous Florida thunderstorms. It was the worst loss I've suffered since my dog passed away five years ago. I had to have another one, and once again, Perfectjammer and my credit card made it happen. I love this thing, and I won't be without one. Again, this is my second. I recommend it 100%. If it was lightning-proof it would be perfect...
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...
4G GPS Signal Blocker Reviews
Now that I have this cell phone jammer I can see why it has so many good reviews. Before getting the blocker we had 30 to 40 unwanted calls a week. Once I use this device, I will get not one call. Since hooking it up one month ago I have manually blocked 11 phone numbers and 19 area codes and I keep getting fewer and few calls. I cannot believe it took me so long to find this device. We had been suffering all the abuse for way too long.. I cannot imagine living with out this product now...
Big Jamming Ranger Signal Blocker For GPS WiFi 3G 4G
My wife and I will shortly become eligible for Medicare. Even though we are listed on the Fed's Do Not Call List, we were plagued morning, noon and night, weekends and holidays on our landline, by telemarketers trying to sell us every Medicare Advantage plan under the sun. Legit ones and scam ones as well. As soon as you start using this cell phone jammer these calls will drop dramatically...
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...
N8P Handheld Cell Phone WiFi GPS Jammer
I can not possibly tell you how very much we LOVE this cell phone jammer! To say I was skeptical would be an understatement but it has delivered everything I had dared hope for. We averaged at least 10 unwanted callers a day; sometimes more, from 9:00 a.m. to 9:00 p.m. every day...
BT8 Cell Phone 3G 4G Jammer
We were sitting around complaining about having to screen our calls from so many telemarketers, and wishing that we had a way to block certain phone numbers, so we took to Perfectjammer and did some exploring and discovered this cell phone jammer. It had great reviews, and now we know why.....it's a great product. Easy to block phone numbers, with the touch of a large red button. And, if you don't reach it in time to push it during the call, you can review the previous calls, and choose which you want to block as well...
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...
4G WiFi Desktop Blocker
AMAZING! I was ready tear out my landline due to the number of unsolicited calls wasting my time. Literally, within the first two days my cell phone jammer stopped over all of these aggravating calls. Now all I have to do is open this device from any extension in our home to eliminate the other unwanted callers. If you make a mistake in blocking someone, you can reverse it. I was a skeptic prior to purchasing, however, now I'M TRULY THRILLED WITH THE RESULTS which has reduced unnecessary stress, wasted time and aggravation in my life...

Portable Military 8 Bands GPS Jammer
Use this cell phone jammer. You can block calls simply by pressing the "Block Now" button if you're around and receive an unwanted call - no need to answer the phone. It also keeps a record of all numbers you receive in the event that an unwanted call arrives while you're not home. You can scroll through the numbers, and press the Block Now button for the pesky ones. You can also delete the telephone numbers you recognize...
Military Powerful GPS Lojack Signal Blocker
This thing is insane. Now when nuisance people call me, the number shows up on the phone or TV, I recognize the number has no reason to call my house, the call is disconnected, and the number is entered into the cell phone jammer so they can't call us again. In the course of just a few days, my wife and I noticed a significant decline in intrusive interruptions from spam callers. The call blocker itself is small and unobtrusive, and very easy to set up...
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...
A12 Powerful GPS Mobile Signal Jammers Comments
In my experience, the cell phone jammer does what it claims extremely well. My house was getting hammered with three or more solicitation calls every day in the late in the afternoon, dinner time or after dinner. My high quality cordless system blocks calls, but we ran of blocking capacity!! We could not block any more numbers using our cordless phone system. So we purchased a jamming device to hook it to our cordless phone system and it worked great...

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. In the 2 weeks since I installed the Cell Phone Jammer, I've had to block a grand total of only 13 calls - less than one per day. The 5000 blocked numbers it has built in clearly do most of the trick...

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.
