Frequently Asked Questions

Q: Why choose us for cooperation?

A: We have professional engineers to develop products suitable for worldwide use. We provide continuous support and respond to any issues promptly.

Q: Does the signal booster have radiation?

A: Yes, but minimal. The booster actually reduces radiation during calls by improving signal strength, as weak signals cause phones to emit more radiation. Safe for indoor use.

Q: Can I install a signal repeater myself?

A: Absolutely. No technical expertise required. Each kit includes everything needed with simple instructions for home/office installation.

Q: Can this mobile signal repeater create a signal where there is no cell signal before?

A: The mobile signal repeater cannot produce a signal, only amplify a weak existing one.
