Signal Boosters in Cuba: Do They Really Work?

Wednesday, January 29, 2025 by Isabella Rojas

A Cuban TikTok user known as Aprendedora (@aprendedorajeje) has stirred up social media by revealing the truth behind a so-called "signal booster" for mobile phones. These so-called boosters are essentially gold-colored stickers that vendors claim can enhance phone reception. They are available on online platforms like Temu, selling at a rate of seven for just one dollar.

In her video, Aprendedora explains that she was encouraged by numerous recommendations to try out a signal booster. Trusting these reviews, she purchased one for 500 Cuban pesos. However, after applying it to her phone, she experienced no improvement in connectivity. "I bought the most expensive sticker in the world, but at least it looks pretty... Right?" she joked while showing how her phone remained disconnected from the network.

The comments section of her post was filled with users who shared similar experiences. "I bought it too and it doesn't work. It's a scam," one user lamented. Despite the mounting evidence and testimonials, some people still hold on to the belief in the product's supposed effectiveness. A few individuals insist that the golden sticker has "advanced technology" and purchase it hoping for better connectivity.

Aprendedora's video has acted as a cautionary tale for others, helping to prevent more people from falling victim to this tech scam that circulates widely in the Cuban black market.

Why Don't These Signal Boosters Work?

The sticker-style signal boosters marketed for mobile phones are ineffective and often a fraudulent product. These items claim to improve phone reception by adhering to the back of the device, but they lack any real technology to significantly amplify the signal.

Absence of Real Amplification Mechanism: A true signal amplifier requires active electronic components like external antennas or repeaters, not merely an adhesive strip.

Inability to Enhance Reception: Mobile phone signals depend on radio waves, which need specialized hardware to be properly captured and boosted.

Lack of Scientific Evidence: There are no genuine studies or technical evidence supporting the efficacy of these stickers.

Marketing Gimmick: They often use buzzwords like "nanotechnology" or "enhanced frequency," but in reality, they are just pieces of metal or plastic without any real functionality.

Real Alternatives to Enhance Mobile Signal

Consider using mobile signal repeaters as they can capture weak signals and amplify them within buildings.

Utilize Wi-Fi Calling. If you have poor signal strength, you can make calls over a Wi-Fi network.

Change your location when using your phone. Sometimes moving to an open area or near a window can improve signal strength.

Opt for a phone with a better antenna. Some phone models have superior signal reception capabilities than others.

In conclusion, these "magical" stickers promising improved signal strength are nothing more than a scam and have no real impact on reception quality.
