menu_default hide_default

Cellular data or mobile data is absolutely essential for the proper running of your device. For example, there are apps on your device that cannot work without access to the internet and when your device is not connected to Wi-Fi, you will need to rely on cellular data for this connection. This is one of the reasons why your device will become useless when mobile data is not working.

We have received numerous emails from Samsung users, particularly those with the Samsung Galaxy S7 who have reported this problem in great detail. Here's one of the many complaints we have received: 


I am unable to get mobile data when in a roaming area. This means I can't get the weather app and email to work on my Samsung S7. Can you please help? I really need to get rid of this annoying issue!

There are several signs that indicate the presence of this particular connection issue. They include the following:

  • You may be unable to load web pages in a browser. 

  • When Google Play is stuck on "Loading..." when you're trying to download or update an app.

  • Downloads may also fail to start, time out or download progress may remain at 0%. 

  • Certain apps like Google Maps, WhatsApp or YouTube don't work properly. 

Part 1. 4 Simple Checks to Fix Mobile Data Not Working on Samsung Android

The following are just some of the simple checks or solutions you can try when mobile data doesn't work on your Samsung.  

1. Check the Network Mode

The first thing you should do when faced with this problem is to check the network mode you are using. For example, if your device is a 4G phone, you need to ensure that the preferred network mode is set as "4G".

To check the network mode go to Settings > Mobile Data > Network Mode and switch to the preferred network mode.


2. Check Mobile Data Limitation

It is also possible that you are experiencing problems with mobile data because you have reached the mobile data limit. You may have forgotten to increase the mobile data limit set previously. To check the mobile limit, follow these simple steps:

Step 1: Go to Settings > Mobile Data/Data Usage.

Step 2: You will see a graph that has been tracking your data usage. You can simply drag the limits up and down to increase or decrease the limit as possible.

Step 3: Uncheck the box "Limit Mobile Data Usage" to remove this limit completely. 


3. Check Your SIM Card

To make sure that it is not the SIM card causing these problems, you need to remove the SIM card and re-insert it back on to your Samsung. Once you reinsert the SIM card into the device, check if the problem persists.


4. Reset APNs to Default

The Access Point Names (APNs) enable your mobile network provider to connect the device to the internet. It may, therefore, make sense to reset APNs to default when you're facing mobile data connectivity issues. Here's how to do it: 

Step 1: On your device, go to Settings > Mobile Data (this could be Wireless Controls or Wireless & Networks on some devices).

Step 2: Tap on "Mobile Networks > Access Point Names.

Step 3: You should be able to see a list of various APNs, now tap on the three dots at the top corner and select "Reset to Default".
