**Finding frequency show on your phone**  
Take United Kingdom EE mobile carrier as an example, EE mobile service worked on frequencies as following:  
**\- 2G** 1800Mhz  
**\- 3G** 2100Mhz  
**\- 4G/LTE** 800Mhz, 1800Mhz, 2600Mhz  
  

\* 2G is used by mobile carrier to delivery their voice calls & text mobile service.

#### 2

**Choose the same frequency boosters**  
Here assume EE 4G frequency show on your phone is 1800Mhz, better signal you needed and correct frequencies for workable boosters as following:  
  

Better Signal You Needed

Correct Frequencies for Workable Boosters

2G or 4G or 2G & 4G

1800Mhz

3G

2100Mhz

2G & 3G or 3G & 4G or 2G & 3G & 4G

1800+2100Mhz

  
If you need better EE 2G & 4G signal, so choose 1800Mhz from **Frequencies** catalogue.

#### 3

**Filter coverage**  
Your area need to be covered with improved signal if up to 250 sq meters, select coverage 250m2 then you will get the best workable booster.  
  
If booster is used to improve vehicle signal, you will also get the best workable booster.  
  

\* Dual Band boosters:  
800+1800Mhz (Band 20, 3) - For 4G/LTE & Calls  
900+1800Mhz (Band 8, 3) - For 4G/LTE & Calls  
900+2100Mhz (Band 8, 1) - For 3G & Calls  
and Tri Band boosters: 900+1800+2100Mhz (Band 8, 3, 1) - For Calls & 3G & 4G/LTE, they are an **ESSENTIAL** if many people in the same household are on different mobile phone networks! It **also means** if you have a 4G ready phone, but area will support 4G later, you’ll still be able to use 3G, or 2G for call.

# Finding frequency show on Samsung Galaxy Phone

This article will explain the easiest steps you can take to see what frequency your phone connects to your network on. This is useful information to have, especially if you are looking to purchase a mobile repeater. Knowing your frequency will allow you to select the best suited booster for the job.  
  
Your phone will use one of these 5 frequencies  
![mobile phone signal booster frequencies](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/QuickStartGuidefrequencybanner_png.jpg?v=1600502371)

##### 800MHz (Band 20)

##### 900MHz (Band 8)

##### 1800MHz (Band 3)

##### 2100MHz (Band 1)

##### 2600MHz (Band 7)

(Band numbers are just easy to read lables )  
  
Lets find out which one it is!  
  
Here is how the **networks** and **frequencies** relate to each other:  

##### **4G (aka lte)** is either at **800**, **1800** or **2600Mhz**

##### **3G (aka wcdma)** is either at **900** or **2100Mhz**

##### **GSM** is always at **900Mhz**

  

## FIELD TESTING ON SAMSUNG GALAXY

1\. Ensure **mobile data** is switched **on**:  
2\. Ensure **WIFI** is switched **off**  

![android on off](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/QuickStartGuideandroidonoff.jpg?v=1600502375)

  
  
**2)** Type in **\*#0011#** into the area that you would normally use to punch in a telephone number.  
  
You are now in **ServiceMode**:  
  
Here you should be able to see the Band number directly. It’s that easy!  
  

##### 800MHz (Band 20)

##### 900MHz (Band 8)

##### 1800MHz (Band 3)

##### 2100MHz (Band 1)

##### 2600MHz (Band 7)

  
However, sometimes on older phones, the Band is NOT shown and instead, it will just say **GSM900** or **WCDMA(900)** or **WCDMA(2100)**. This is still easy to read.  
  

##### GSM900 = 900Mhz

##### WCDMA(900) = 900Mhz

##### WCDMA(2100) = 2100Mhz

(WCDMA is just 3G)  
  
Below are 2 examples. The first phone is in an area where there is **4G**, and the second where there is only **3G**.  
  

![android LTE](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/QuickStartGuideandroidLTE.jpg?v=1600502382)  
![android wcdma](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/QuickStartGuideandroidwcdma.jpg?v=1600502383)

  
  
In the first image, you can see the phone is connected to **Band 20**. This is **800Mhz**, so that’s **4G** is at **800Mhz**  
In the second image, we are connected to (WCDMA(900)). The (900) means **900Mhz**. The WCDMA means 3G. So that’s **3G** at **900Mhz**.  
Some phones may only show UARFCN numbers, so in both these images I have also highlighted the UARFCN number (in this case, 6300 and 3088 respectively)  
  

[![find frequency umto tool](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/QuickStartGuideumtotool.jpg?v=1600502368)](https://www.cellmapper.net/arfcn?)

  
  
If your phone only shows UARFCN values, you can put these numbers into the UARFCN-to-frequency converter above.  
Now that you know the frequency / band that your phone connects to outside your house, you can select the best signal booster for you.  
If you see no symbol or the **‘E’** or **‘G’** symbol , we suggest the 900Mhz booster. This one is easy!  
If you see the **3G**, **H**, **H+** symbol then you must find out by the method above whether you are at **900Mhz** or **2100Mhz**.  
Finally if you see the **‘4G‘** or **‘LTE’** symbol, then you must use the method above to find out are you connected to **800**, **1800** or **2600Mhz**, and then select the appropriate booster for the list.

##### Daniel

I’m not sure but I have a iPhone and followed the directions above and I have band number 4 with 2140 MHz and 1740 MHz. My band name is AWS-1. Just curious if I’m reading this right becsuse there is not a band 4 for an iPhone above. Any help would be great.  

![frequency band 4 aws 1700MHz](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/QuickStartGuideBand4.png?v=1600502378)

  
  
Band 4 is an LTE (4G) band for the frequency 1700Mhz  
This is a **USA frequency** and is not applicable for Europe.

I have found the information very helpful, I have an APP installed on my android (Samsung A5) called Network Signal Pro. which shows me all the information. In my office at home I am only on edge 2G with signal strength -101 \*6ASU moving around the house I can get H 3G -99 \*5ASU but it varies so much. Outside I can get 3G -89\* 12 ASU I know on the roof I get 4G with full signal.
