What is a mobile signal booster? - A mobile signal booster is a device that helps improve mobile phone reception in areas where the signals are weak. It picks up the existing mobile signals from outside and amplifies them, allowing for clearer calls and faster data when you're in your car or caravan. 2. How does the PrimeTel mobile signal booster work? - The PrimeTel mobile signal booster works by receiving weak mobile signals outside your vehicle and boosting them inside. It operates on two frequency bands, 900MHz (Band 8) and 1800MHz (Band 3), which are used by mobile networks in the Czech Republic. This means you can enjoy better voice calls, text messaging, and 4G LTE internet access. 3. Is it difficult to install the booster in my vehicle? - No, installing the booster is easy! The kit comes with everything you need, including installation instructions. You just need to connect the external aerial to the booster inside your vehicle, and you're set to go! 4.

This means it can help improve service for anyone using these networks in your vehicle. 5. How many people can use the signal booster at once? - The mobile signal booster can support up to 15 users at the same time. This makes it great for families or groups traveling together in one vehicle. 6. What should I do if I have no signal outside? - Unfortunately, the booster can only amplify existing signals. If there are no mobile signals outside your vehicle, the booster won't be able to help. Make sure you check for signal strength in your area before expecting the booster to work. 7. Will the booster reduce my phone's radiation? - Yes! By improving the signal strength, your phone doesn't have to work as hard to connect, which can reduce the radiation it emits. This makes it safer to use your phone while improving your mobile service. 8. Can this booster work while I'm driving? - Absolutely! The PrimeTel mobile signal booster works while the vehicle is in motion. As long as it has a signal to boost, you can enjoy improved communication even while you're on the road. 9. What is the coverage area of the booster? - The coverage area provided by the booster can vary based on external conditions, like the strength of the signal outside. However, it aims to extend the coverage within your vehicle, allowing you to enjoy better connections. 10. How can I check what frequency band my phone uses? - To check the frequency band on an iPhone, simply dial \*3001#12345#\* and press the call button.
