How Do I Know if My iPhone is 4G or 5G?

The world of cellular technology is constantly evolving, and with each new generation comes faster speeds and improved connectivity. The latest advancements have ushered in the era of 5G, promising blazing-fast download and upload speeds, lower latency, and a smoother user experience. But if you’re unsure if your iPhone supports 5G, you might be left wondering if you’re missing out on these benefits.

This comprehensive guide will walk you through all the ways to check if your iPhone is 4G or 5G, ensuring you can unlock the full potential of your device.

Checking Your iPhone’s Model Number

The most reliable way to determine if your iPhone supports 5G is to check its model number. Apple assigns a unique identifier to each iPhone model, and this number can reveal crucial information about its capabilities, including 5G support.

  1. Open Settings: Navigate to the “Settings” app on your iPhone.
  2. General: Scroll down and tap on “General”.
  3. About: Select “About” to access detailed information about your device.
  4. Model: Look for the “Model” entry. This is the most important piece of information.

Now, let’s decode your iPhone’s model number:

  • iPhone 12 and newer models: If your model number starts with “iPhone12”, “iPhone 13”, “iPhone 14”, or any subsequent number, you are guaranteed to have a 5G-capable device.
  • iPhone SE (3rd generation): The third-generation iPhone SE released in 2022 also boasts 5G support.
  • Older models: If your model number falls outside the range mentioned above, your iPhone is likely a 4G device.

Important Note: While the model number provides a good indication, it’s crucial to remember that 5G availability is also dependent on your carrier’s network coverage in your location.

Examining Your iPhone’s Cellular Settings

Another helpful method for determining your iPhone’s 5G capability is by directly checking your cellular settings.

  1. Open Settings: Go to the “Settings” app on your iPhone.
  2. Cellular: Select “Cellular”.
  3. Cellular Data Options: Tap on “Cellular Data Options” (this option may vary slightly depending on your iPhone’s operating system).
  4. Voice & Data: Look for the “Voice & Data” option. This setting displays the current network your iPhone is using.

Interpreting the Results:

  • 5G: If you see “5G” listed as your current network, congratulations! Your iPhone is connected to a 5G network, and you’re enjoying the benefits of faster speeds.
  • LTE: If you see “LTE” displayed, your iPhone is connected to a 4G network. This doesn’t necessarily mean your device lacks 5G support, but it suggests you’re in an area where only 4G coverage is available.

Exploring Your Carrier’s Network Coverage

Even if your iPhone is 5G-compatible, the availability of 5G services depends entirely on your carrier’s network infrastructure and coverage in your area.

  1. Check your carrier’s website: Most major carriers provide detailed maps highlighting their 5G network coverage areas. Visit your carrier’s website and search for “5G coverage” or “network coverage map”.
  2. Contact your carrier: If you’re unsure about 5G coverage in your specific location, reach out to your carrier’s customer service for assistance.

Understanding the Benefits of 5G

Now that you’ve successfully confirmed your iPhone’s 5G capability, you might be curious about the advantages of this advanced technology.

  • Faster download and upload speeds: 5G networks deliver significantly faster download and upload speeds compared to 4G. This translates to faster app downloads, smoother video streaming, and quicker file transfers.
  • Lower latency: 5G boasts significantly lower latency, meaning there is a shorter delay between sending a request and receiving a response. This is especially beneficial for real-time applications like online gaming, video calls, and virtual reality experiences.
  • Improved capacity: 5G networks can handle a much higher volume of data traffic compared to 4G, resulting in a more reliable and consistent connection, especially during peak hours.

Key Considerations

While 5G promises a superior mobile experience, it’s important to keep in mind some key considerations:

  • Device Compatibility: Not all iPhones support 5G. As mentioned earlier, only iPhones 12 and newer models, along with the third-generation iPhone SE, are 5G-compatible.
  • Network Coverage: 5G coverage is not yet ubiquitous. Even if your iPhone supports 5G, you may find yourself limited to 4G speeds in certain areas.
  • Battery Life: 5G technology is energy-intensive, and you might experience a slight decrease in battery life when using 5G networks.


Determining whether your iPhone is 4G or 5G is a straightforward process. By checking your model number, exploring your cellular settings, and understanding your carrier’s network coverage, you can easily identify your iPhone’s capabilities.

Remember, while 5G offers many advantages, it’s important to be aware of potential limitations such as device compatibility and network coverage. If you’re fortunate enough to have a 5G-capable iPhone in an area with extensive 5G coverage, you’ll be rewarded with lightning-fast speeds and a seamless mobile experience.


How do I know if my iPhone is 4G or 5G?

You can find out if your iPhone is 4G or 5G by checking your phone’s specifications or by looking at the cellular data settings on your device.

To check your phone’s specifications, go to the Apple website and search for your iPhone model. The product page will list the phone’s cellular capabilities. If your iPhone has 5G capabilities, the product page will state this explicitly. If it doesn’t mention 5G, your iPhone is likely a 4G model.

What are the differences between 4G and 5G?

4G and 5G are two different generations of cellular technology. 5G is the latest generation and offers faster download and upload speeds, lower latency, and greater capacity compared to 4G.

5G also supports new technologies like network slicing and edge computing, which can enhance various applications, from gaming and streaming to industrial automation and healthcare.

How do I enable 5G on my iPhone?

To enable 5G on your iPhone, go to Settings > Cellular > Cellular Data Options and select 5G Auto or 5G On.

5G Auto will prioritize 5G networks when available, but it will automatically switch to 4G if the 5G signal is weak or unstable. 5G On will force your iPhone to connect to 5G networks, even if the signal is weak, which may result in slower speeds and increased battery consumption.

Can all iPhones connect to 5G networks?

Not all iPhones can connect to 5G networks. Only iPhones released after the iPhone 12 series support 5G.

Older iPhones like the iPhone 11 and earlier models are limited to 4G networks. If you have an older iPhone and you want to use 5G, you’ll need to upgrade to a newer model.

Will using 5G drain my iPhone battery faster?

Yes, using 5G can drain your iPhone battery faster than using 4G. This is because 5G networks require more power to transmit data.

If you’re concerned about battery life, you can try switching to 4G or 5G Auto mode, which will automatically switch to 4G when a strong 5G signal is unavailable.

Does my carrier support 5G?

To use 5G on your iPhone, your carrier must also support 5G in your area.

You can check with your carrier to see if they offer 5G service and if it’s available in your location. Not all carriers offer 5G coverage nationwide, and even in areas where 5G is available, coverage may vary.

Should I upgrade to a 5G iPhone?

Whether or not to upgrade to a 5G iPhone depends on your individual needs and priorities. If you’re looking for the fastest possible download and upload speeds, then a 5G iPhone is a good option.

However, if you don’t rely heavily on fast internet speeds or if 5G coverage is limited in your area, a 4G iPhone might be more suitable.
