What does a mobile signal booster do? - A mobile signal booster helps to improve your phone's reception.

Who can benefit from using the booster? - Anyone can benefit from using a mobile signal booster, especially if you live in an area with weak mobile signals. This includes families with members on different phone networks, people in small apartments, or those who work in offices where the signal is poor. 3. Can I use the booster for any phone network? - Yes! Our mobile signal booster works with all major networks in Switzerland, including Swisscom, Sunrise, Salt, Yallo, and many others. This means that no matter which network you use, you can enjoy better signal strength. 4. How much area does this booster cover? - The booster can cover an area of up to 200 square meters, making it perfect for small apartments or offices. If you need coverage for a larger space, upgrades are available. 5. What if I don’t have a signal outside? - It’s important to know that a signal booster can only make weak signals stronger. If there is no signal outside, the booster won't work. To use it effectively, you need some outside signal. 6. How do I know if my phone supports 4G Calling? - You can check if your phone supports 4G Calling (VoLTE) by dialing \*3001#12345#\* and following the instructions to find the frequency band on your device.

This way, you can place the antennas in locations that will give you the best signal possible. 9. What is the upgrade option for better performance? - For enhanced performance, you can upgrade to a higher gain outdoor antenna if your phone shows low signal bars indoors. This helps increase the strength of the signal being boosted. 10. What protects my equipment from lightning? - You can add a lightning surge protector to your system. This device helps keep your booster safe from damage caused by lightning strikes and is easy to install.
