Cell Phone Booster Sticker - Unbranded

The sticker contains a passive element designed to interact with your device's internal antenna, potentially reflecting or focusing radio waves to improve reception in weak signal areas. It does not actively amplify signals.

Yes, the sticker is designed to be universally applicable to any analog, digital, and tri-band phone, regardless of the model.

While it can be moved, repeated removal and reapplication may weaken the adhesive. It is best to apply it to its intended device.

This is a passive sticker that aims to enhance reception by modifying how the device's antenna interacts with radio waves. An active signal booster typically uses power to amplify incoming and outgoing signals.

The color of the sticker (typically black and gold) is cosmetic and does not affect its performance.

The sticker's adhesive is designed for long-term use, but its effectiveness might gradually decrease over a very long period or with exposure to extreme conditions. Proper care will help maintain its integrity.

This sticker is specifically designed to enhance cellular and radio frequencies, not Wi-Fi signals.

Ensure the sticker is applied correctly to a clean surface. Signal improvement is not guaranteed and depends heavily on your location's network coverage and environmental factors. Try moving to a different location to test.

Ensure the surface of the device is clean, dry, and smooth before application. Press down firmly after applying. If adhesion is still poor, the surface may be textured or unsuitable.

Remove the sticker and reapply it, ensuring correct placement. In rare cases, the sticker might interfere with very specific antenna designs. Test without the sticker to confirm if it is the cause.
