Frequently Asked Questions
Why choose us for cooperation?
We have professional engineers to develop products suitable for global markets and provide 24/7 technical support to resolve any issues.
Does the signal booster have radiation?
Yes, but minimal. The device actually reduces radiation exposure during calls by improving signal strength, as weak signals cause phones to emit more radiation.
Can this mobile signal repeater create a signal where there is no cell signal before?
No, the mobile signal repeater cannot produce a signal - it only amplifies existing weak signals.
Please feel free to contact us if you have any other questions.
