What is a mobile signal booster? - A mobile signal booster is a device that helps improve your mobile phone signal by amplifying it. This is useful if you have weak reception at home, in cafes, or anywhere else. The booster takes the weak signal from outside, makes it stronger, and sends it inside your building. This way, you can make clearer calls and enjoy faster internet. 2. How does the 3G and Calls booster work? - This booster works on two specific frequency bands, 900MHz and 2100MHz, which are used by mobile networks in Finland. By capturing weak signals outside and boosting them, it helps make your calls clearer, reduces dropped calls, and speeds up data for internet usage. 3. What size area can the 3G booster cover? - The 3G mobile signal booster can cover an area of up to 250 square meters. This means it can effectively strengthen your mobile signal in medium-sized places like homes, cafes, pubs, or small offices. 4. Can I use the booster with any mobile carrier? - Yes, this mobile booster is compatible with all major mobile networks in Finland, including Telia, Elisa, DNA, and more. It strengthens the 3G signals for any phone connected to these networks. 5. How do I know if my phone is using the right frequency? - To check if your phone operates on the 900 MHz or 2100 MHz frequencies, you can use a special code. Simply dial \*3001#12345# and hit the call button. This will give you information about your mobile signal type, helping you understand if the booster will work for you. 6. Can the booster create a signal if there is none? - No, the mobile signal booster can only make an existing weak signal stronger. If there is no signal outside, the booster won’t work. It needs some level of signal to amplify it. 7. What does the installation kit include? - The installation kit includes everything you need: an external antenna to pick up the signal, cables to connect all parts, a booster unit, an internal antenna, and a power adapter. So, you have all the necessary components for installation included in one price! 8. Is it easy to install the mobile signal booster? - Yes, it is designed to be user-friendly, and most people can set it up by following the included instructions. If you have a little bit of technical knowledge, you should find the installation quite straightforward. 9. What if I need a longer cable for installation? - If the standard 10-meter cable length is not enough for your setup, you can opt to upgrade to longer external cables to ensure proper installation and coverage. This way, your booster's location can be adjusted as needed. 10. What is a surge protector, and do I need it? - A surge protector is a device that helps protect your mobile signal booster from electrical surges caused by lightning or other power strikes. It is recommended to keep your equipment safe, especially if you live in an area prone to storms.
