What is a mobile signal booster? - A mobile signal booster helps improve the strength of your mobile phone signal. It works by capturing weak signals from outside, amplifying them, and then broadcasting the stronger signal inside your vehicle or home. This means you will have better calls and faster internet. Imagine it like a megaphone for your phone’s signal! 2. How does the signal booster work? - The signal booster uses an external aerial to catch signals from mobile towers. It then boosts this signal and sends it inside your car or home. If you have a weak signal outside, it will help make phone calls clearer and speed up internet access. Just remember that if there’s no signal at all outside, the booster can’t create one! 3. Will it work for all phone networks? - Yes! The booster is compatible with major mobile networks in Singapore, including SingTel, StarHub, M1, and Circles.Life. Whether you use a smartphone or a simple mobile phone, everyone can enjoy better signal quality. 4. Can I use the booster while driving? - Absolutely! The mobile signal booster is designed for use in vehicles. Just connect it and enjoy better calls and faster internet wherever your travels take you. It’s perfect for family road trips or long drives. 5. What happens if I don’t have a signal outside? - If there's no signal outside, the booster will not be able to help. It amplifies existing signals but cannot create new ones. So, it’s important to have at least some signal from the network outside for it to work. 6. How do I know if my phone supports 4G Calling? - To check if your phone supports 4G Calling (VoLTE), you can look in the settings or use the band checker. For iPhones, dial \*3001#12345#\* and check the 'Freq Band Indicator.' This helps you know if you can make clearer calls using a 4G connection. 7. How do I install the mobile signal booster? - Installing the signal booster is easy! The kit comes with everything you need, like the external aerial and cables. Just follow the simple installation manual included in the package. No special tools are needed, and you can set it up in a short time. 8. Is it safe to use a mobile signal booster? - Yes, using a mobile signal booster is safe. It helps improve signal strength which can actually reduce the radiation your phone emits as it needs less power to connect. Plus, you can unplug it anytime when not in use to eliminate radiation. 9. What if I have different networks at home? - No problem! The dual-band booster can support multiple networks such as SingTel, StarHub, M1, and Circles.Life at the same time. So everyone in your household can enjoy better signal, no matter which provider they use! 10. Can I use the booster in my home? - While this particular booster is designed mainly for vehicles, there are boosters available for home use too. They work similarly by boosting signals inside your house. If improving home signal is what you need, look for a home signal booster!
