What is a mobile signal booster? - A mobile signal booster is a device that improves your phone's signal strength by capturing the existing weak signal from outside, amplifying it, and then rebroadcasting it inside your home or office. This helps you make clearer calls, send texts faster, and enjoy better internet connections. 2. How does the 3G & Calls - 250m2 booster work? - The 3G & Calls - 250m2 booster works by boosting signals from various mobile networks like Three, Telenor, and Telia. It amplifies 3G and 4G LTE signals on two main frequencies, 900MHz and 2100MHz, ensuring you have a better connection for voice calls, texts, and internet data. 3. Can this booster work for any phone? - Yes, the booster is designed to work with all mobile phones that operate on the supported 3G and 4G networks in Sweden. Just make sure your phone uses the right frequency band, which you can check by calling a specific service number or using a signal-checking app. 4. How big of an area can the booster cover? - This booster can cover an area of up to 250 square meters, which is great for medium-sized spaces like homes, cafes, or restaurants. It helps ensure that everyone in that area has a strong mobile signal. 5. Will the booster work if there's no signal outside? - Unfortunately, the booster can only amplify existing signals, not create a new one. If there is no signal outside your building, the booster won’t be able to function properly. You’ll need to ensure there is some outside signal for it to work. 6. What if I need longer cables for installation? - If the standard 10-meter external cable isn't long enough for your installation, you have the option to upgrade to longer cables. This will help you place the external aerial in a better location for capturing stronger signals. 7. What should I do if my phone shows weak signal bars? - If your phone shows only 1 or 2 signal bars indoors, consider upgrading to a higher gain Yagi antenna. This antenna helps with better reception by capturing signals more effectively from outside. 8. Is installation difficult? - No, installation is quite simple! The kit comes with all the necessary components, and you can usually set it up by following the included instructions. If you need help, there are also guides available online. 9. What is the Lightning Surge Protector? - The Lightning Surge Protector is an accessory that helps protect your booster from damage caused by lightning strikes. It can easily be installed and ensures your equipment remains safe in stormy weather. 10. How many users can connect to the booster at once? - The 3G & Calls - 250m2 booster can support up to 25 users simultaneously. This makes it perfect for families or small businesses where multiple people need to connect their phones at the same time.
