**Warming Tips:**
- Band Confirmation: This booster can boost signals on Band 8, or Band 1, please check the band of your devices firstly.
- For iPhone: Dial \*3001#12345#\* → Press call button → Click 'Serving Cell Info' → Check 'Freq Band Indicator'.
- For Android: Download 'LTE Discovery' APP → Click ‘SIGNALS’ → Check 'EARFCN'. More refer to [Quick Start Guide](https://www.ukmobilebooster.com/pages/quick_start_guide) .
- External Signal Needed: The signal booster can only amplify signal but can't create signal. If there is no signal outside, it won't work, please make sure you get 1-2 bars signal outside.
### Custom your solution
#### **Expandable coverage by adding indoor antenna if the outside signal is strong.**
### **How It Works**
#### 1
**Receives signal**
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
#### 2
**Boosts signal**
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
#### 3
**Broadcasts signal**
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
#### **Get stronger signal**
#### Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
#### Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.
#### **Installation**
1. Connect the indoor antenna to the MS port.
2. Connect the outdoor antenna to the BS Port.
3. Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
4. Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
5. Power on the booster and check the signal strength.
6. Adjust the outdoor antenna until you get the best signal strength.
**IMPORTANT NOTE**:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

1. What is a 4G LTE and voice call booster? - A 4G LTE and voice call booster is a device that helps improve mobile phone signals in your home or buildings. If your phone struggles to connect or stay connected to your mobile network, this booster can help make calls clearer, eliminate dropped calls, and improve internet speeds for faster downloads.
2. How does the booster work? - The booster works by capturing the existing signal from your mobile network outside and amplifying it, then sending the stronger signal inside your building. It doesn't create new signals, but rather strengthens the weak ones, making it easier to make calls and use the internet.
3. Is the booster easy to install? - Yes, the booster kit comes with everything you need for installation, including cables and antennas. Most users find it straightforward to set up, even without technical skills. Plus, you can follow the instructions provided to help you with each step.

6. What should I do if I have no signal outside? - Unfortunately, if there is no signal coming from outside, the booster cannot work. It's essential to have some signal strength outside your location for the booster to amplify and improve the signal inside.
7. How can I check which frequency band my phone uses? - You can find out your phone's frequency band by dialing \*3001#12345#\* on an iPhone and pressing call. Look for the 'Freq Band Indicator' in the 'Serving Cell Info' section to see if it's band 8 or band 1.
8. Do I need to upgrade the external cables or aerial? - If the standard 10-meter external cable included in the kit is not long enough for your space, you have the option to upgrade. Similarly, if you want even better performance indoors, consider upgrading to a higher gain Yagi antenna.
9. What is a lightning surge protector, and do I need one? - A lightning surge protector is a device that safeguards your equipment from damage caused by lightning strikes. It's a wise choice to use one, especially if your antenna is exposed to the outside, as it helps protect your booster from electrical surges.
10. Can the booster support multiple users at once? - Yes, this booster can support up to 25 users simultaneously, making it great for larger households or businesses where many people need to use their phones or internet at the same time.
