Doesn’t work in my area. It may work in more populated areas

Okay I've seen other reviews here that panned this little device, saying it doesn't work. I bought these for our Samsung phones, since we've been getting horrible reception and signal strength in our section of Houston Texas.I've used a similar product in the past, when you could still get to the battery in the phone. On a Samsung, without some specialized tools, you aren't able to remove the cover.These are designed to be used either inside the phone case, or on the back of the phone.I installed them on the back of our phones, power cycled the phones, and immediately went from 2 bars to FIVE (5) BARS!. We've especially had problems on our property, which is 15 acres in semi rural Houston. The nearest cell tower is approximately 1.5 miles away.Cell call quality is crystal clear, with no drops or static in the calls. I also went for a drive with the phones and signal strength remained between 4 and 5 bars on all phones. Considering that last night, I couldn't get more than 2 bars anywhere on our property and at most 3 bars off the property, I consider this a firm winner.My wife has her phone out at our property about 80 miles west of Houston, with the nearest tower almost two miles away and she is shocked at the strength and quality.My son is in downtown Houston right now and he just called me to let me know he's getting a solid 5 bars.Here's the one thing they don't tell you on the package but you'll want to do it. Take an alcohol pad and thoroughly wipe down the area you want to apply the sticker. Let it dry completely for five minutes, and then apply the sticker. DON'T touch the adhesive on the sticker, and smooth it down so that there are no air bubbles using the adhesive pad cover.Power cycle the phone and you should be rocking and rolling.5 stars from us!

Does not work not worth the money

put on four stickers. helped signal a lot.

any strength increase was very little if any

Not the best, but it works.. gives you enough signal where you didnt

Total Garbage 🗑️ useless stickers..what a disappointment

Espero ver como funciona lejos de la ciudad
