The Samsung Galaxy S3, released in 2012, was a flagship device that boasted impressive specs and features for its time. One of the key features that set it apart from its competitors was its support for 4G networks. However, some users may find that their device is not connecting to 4G networks, or that the option to enable 4G is missing from their settings menu. In this article, we will explore the steps you can take to turn 4G on your Galaxy S3 and troubleshoot any issues that may be preventing you from accessing 4G speeds.
Checking Your Device’s 4G Compatibility
Before we dive into the steps to enable 4G on your Galaxy S3, it’s essential to check if your device is compatible with 4G networks. The Galaxy S3 was released in several variants, and not all of them support 4G. To check if your device supports 4G, follow these steps:
Checking Your Device’s Model Number
To check your device’s model number, go to Settings > About device > Model number. The model number should be displayed on the screen. Check if your model number matches any of the following:

If your device’s model number matches any of the above, it should support 4G networks.
Checking Your Carrier’s 4G Coverage
Another essential factor to consider is your carrier’s 4G coverage in your area. Even if your device supports 4G, you won’t be able to access 4G speeds if your carrier doesn’t offer 4G coverage in your area. Check your carrier’s website or contact their customer support to see if they offer 4G coverage in your area.
