**Warming Tips:**  
-   Band Confirmation: This booster can boost signals on Band 3, 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**

  

![how mobile signal booster 3G 4G LTE booster E-Plus network booster Aldi Talk signal amplifier Blau mobile enhancer Ortel 4G booster indoor coverage solutions mobile signal enhancement work for home office](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/ProductPageHIWhomeoffice-2.webp?v=1650634397)

#### 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.

![how mobile signal booster 3G 4G LTE booster E-Plus network booster Aldi Talk signal amplifier Blau mobile enhancer Ortel 4G booster indoor coverage solutions mobile signal enhancement work for home office](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/ProductPageboostedcoverage-2.webp?v=1650634397)

#### 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.  Q: What is a Mobile Signal Booster?  
    A: A mobile signal booster is a device that helps improve the strength of your mobile phone signal. It works by receiving weak signals from the outside and amplifying them so that your phone can connect better, giving you clearer calls and faster internet.
2.  Q: How does this booster work?  
    A: The booster has three main steps: First, an outdoor antenna picks up the weak signal. Second, the booster amplifies that signal. Finally, an indoor antenna broadcasts the strengthened signal, allowing your devices inside to connect seamlessly.
3.  Q: Who can use the 3G & 4G LTE Booster?  
    A: This booster can be used by anyone who has poor mobile signal in their home, office, or other spaces. It's especially good for those using networks like E-Plus, Aldi Talk, or Blau, making it perfect for families or small businesses!
4.  Q: Can I use this booster with multiple devices?  
    A: Yes! The 3G and 4G LTE booster allows up to 25 users and devices to connect at the same time. This means everyone in your home or office can enjoy a better mobile signal.
5.  Q: What area does this booster cover?  
    A: This mobile signal booster can cover up to 250 square meters. That means it can boost signals in medium-sized areas like a large living room, cafe, or even a small restaurant.
6.  Q: Do I need a good outside signal for this to work?  
    A: Yes, for the booster to work effectively, you need at least a weak signal (1-2 bars) from outside. The booster strengthens this existing signal, but it cannot create one if there is none.
7.  Q: Is it easy to install the booster?  
    A: Yes, installing the mobile signal booster is quite simple! You'll just need to connect the antennas and follow the set-up instructions provided. No special skills are required!
8.  Q: What if I need more coverage?  
    A: If you need even more coverage, you can add extra indoor antennas to the system. This can further spread the signal throughout larger areas.
9.  Q: Will this booster work for all mobile providers?  
    A: The booster is compatible with several mobile networks in Germany, including E-Plus, Aldi Talk, Blau, and more. Make sure to check if your provider is listed for the best results.
10.  Q: Can I upgrade my booster if I want better performance?  
     A: Yes, you can upgrade components like the external cable or antenna for better performance. These upgrades can help if you’re having trouble getting a good signal indoors.
