What is a mobile phone signal booster? - A mobile phone signal booster is a device that helps to improve the quality of your mobile phone signal. If you often experience weak signals or dropped calls, this device can amplify the existing signal from outside, making it stronger inside your home or building. It works on different frequency bands to enhance voice calls, texts, and data services. 2. How does the 4G LTE signal booster work? - The 4G LTE signal booster works by capturing the weak signal available outside your building. It then amplifies that signal and relays it inside, ensuring you have better reception for calls and data. Remember, if there is no signal outside, the booster cannot create one; it can only enhance what’s already there. 3. Can I use this booster if I have different mobile carriers? - Yes, this signal booster is compatible with multiple mobile carriers, including Heyah and Nju Mobile. It works on 900MHz and 1800MHz frequencies, which means it can help improve signal for those on different networks in the same household. This is particularly useful if family members use different mobile services. 4. How much area does the booster cover? - The 4G LTE and Calls signal booster is designed to cover indoor areas of up to 250 square meters. This makes it ideal for homes, cafes, restaurants, and other medium-sized places where several people may need a good signal. 5. What do I need to install the booster? - The kit comes complete with everything you need to install the signal booster, including an external aerial, cables, the booster unit, an internal aerial, and a power adapter. With this complete package, you won’t need to buy anything extra for installation. 6. What should I do if I still have weak signal after installation? - If you are still experiencing weak signal after installing the booster, check to make sure the external aerial is positioned in an area with good signal. You may need to upgrade your external aerial or cables to improve performance, especially if the signal outside is very weak. 7. Does this booster work for 4G calling? - Yes, if your phone supports 4G calling, also known as Voice over LTE (VoLTE), and if 4G calling is available in your area, the booster will enhance this service, allowing for clearer voice calls over the 4G network. 8. How do I check which frequency band my phone uses? - To check the frequency band your phone uses, you can dial \*3001#12345#\* and press the Call button. Then, click on 'Serving Cell Info' to find the 'Freq Band Indicator'. This will tell you if your phone uses Band 8 or Band 3. 9. Can I upgrade the components of the booster? - Yes, you have the option to upgrade components such as the external cables and aerial. If the standard package doesn’t cover your area sufficiently, upgrading to a higher gain antenna or longer cables can improve the performance of the signal booster. 10. Is the signal booster easy to install by myself? - Yes, the signal booster kit includes detailed instructions that make it easy to install yourself. Most people can set it up without needing a professional, and it typically takes just a couple of hours to complete the installation.
