1.  What is a 3G signal booster for cars? - A 3G signal booster is a device that strengthens the cellular signal in your car. It helps you make clear calls and have better internet access while driving. This is especially useful if you're in areas with weak mobile coverage.
2.  How does the 3G signal booster work? - The booster works by receiving the existing weak signal outside your car, making it stronger, and then sending that improved signal inside. This way, you can enjoy clearer phone calls and faster internet speeds without interruptions.
3.  Which mobile networks does it support? - This signal booster supports major Indonesian mobile networks like Telkomsel, Indosat, and XL Axiata. It enhances signals for both 3G and 2G services on these carriers.
4.  Can I use the booster if there's no signal outside? - No, if there's no cellular signal outside your car, the booster won't work either. It can only amplify an existing signal, so it's best to be in an area with at least some signal strength.
5.  Is the installation complicated? - Not at all! The kit comes with everything you need for installation, and it’s designed to be easy to set up. You don’t need any special skills, just follow the instruction manual included in the kit.
6.  How many devices can use the booster at the same time? - The booster can support up to 15 devices at once. This means you and your family or friends can all enjoy better phone service on your devices while in the car.
7.  Does the booster cause any harm or radiation? - The booster is designed to reduce the radiation exposure from your phone by providing a stronger signal. This means your phone doesn’t have to work as hard, which is better for you.
8.  What is the coverage area of the booster? - The booster improves the signal coverage inside your vehicle, making sure you can make calls and use the internet reliably as long as there's a base signal outside.
9.  What is automatic gain control in the booster? - Automatic gain control adjusts the booster's strength according to the outside signal. If the signal is weak, it boosts it more. If it's strong, it boosts less. This helps maintain a clear and stable connection.
10.  Can I use the booster outside my vehicle? - The booster is specifically designed for vehicles. While the equipment itself could theoretically be used outside, it works best in a car environment where it can properly receive and amplify signals.
