How to turn on LTE on iPhone 12: A Step-by-Step Guide

Turning on LTE on your iPhone 12 is a straightforward process that allows you to enjoy faster data speeds for browsing, downloading, and streaming content on your device. By following a few simple steps, you can enable LTE and make the most out of your iPhone’s capabilities.

Step by Step Tutorial to Turn On LTE on iPhone 12

Before we dive into the steps, let’s understand what we’re aiming to achieve. Enabling LTE on your iPhone 12 will allow your phone to connect to your cellular provider’s LTE network, which is typically faster than the regular 3G or 4G networks.

Step 1: Open the Settings App

Access the Settings app on your iPhone 12 by tapping on the gear icon.

Opening the Settings app is your gateway to modifying various functions on your iPhone, including network and connectivity settings.

Step 2: Tap on Cellular

In the Settings menu, tap on the "Cellular" option.

The Cellular settings contain all the options related to your phone’s connection to the cellular network, including data usage and network selection.

Step 3: Tap on Cellular Data Options

Once in the Cellular menu, tap on "Cellular Data Options."

This submenu allows you to manage settings specifically related to your cellular data, such as roaming and network selection.

Step 4: Tap on Voice & Data

Now, tap on "Voice & Data" within the Cellular Data Options.

In this section, you can choose the type of network your iPhone will use for voice calls and data.

Step 5: Select LTE

Finally, select "LTE" from the list of options available under Voice & Data.

By selecting LTE, you are telling your iPhone to use the LTE network whenever it’s available, which should give you a faster internet connection.

Once you’ve completed these steps, your iPhone 12 will connect to the LTE network provided by your cellular carrier, assuming you are in an area with LTE coverage. You should notice an improvement in data speeds, making your online experience smoother and more efficient.

Tips for Turning On LTE on iPhone 12

  • Ensure that your cellular plan supports LTE. Not all carriers or plans include access to LTE networks.
  • Check if you’re in an area with LTE coverage. LTE won’t work if your carrier doesn’t provide it in your current location.
  • Keep in mind that using LTE may result in higher data consumption, which could lead to additional charges if you have a limited data plan.
  • If you notice that your battery is draining faster with LTE enabled, consider switching to a lower network mode when you don’t need high-speed data.
  • Remember to turn off LTE if you’re traveling abroad to avoid potential roaming charges, unless you have an appropriate roaming plan.
