Understand what 5G actually does differently

~38s

5G is faster than 4G LTE — often 10-100 times faster in ideal conditions. What does that mean practically? Web pages load faster. Videos start playing immediately without buffering. Large file downloads (like app updates) finish in seconds instead of minutes. In crowded places like sports stadiums, concerts, or shopping centers, where thousands of people are using their phones simultaneously, 5G handles the load much better than 4G — which often slows to a crawl in crowds.

Quick Tip

Quick Tip: For most daily tasks — checking email, browsing Facebook, making calls, watching a video — the difference between 4G and 5G is barely noticeable on an individual basis. 5G matters most for heavy data users and crowded environments.

Find out if your phone has 5G

~27s

Most new smartphones sold in 2022 and later support 5G. To check your iPhone: go to SettingsGeneralAbout → look for "5G" in the model description or check the Apple website for your model. On Android: go to SettingsAbout phone → see if 5G is listed in specifications. Alternatively, if you see "5G" or "5G UC" in the signal indicator in the top corner of your phone screen, your phone is connected to a 5G network.

Know which type of 5G you are getting

~31s

There are two main types of 5G: "Sub-6 GHz" 5G and "mmWave" 5G. Sub-6 GHz is the most common — it covers most US cities and suburban areas and is available from all major carriers. It is moderately faster than 4G. mmWave 5G is extremely fast but only covers a small area (roughly a city block) around a 5G antenna — typically found in dense urban areas, airports, and stadiums. If you see "5G UW" (Verizon), "5G UC" (T-Mobile), or "5G+" (AT&T) in your signal bar, you are on the faster version.

Decide whether to upgrade your phone for 5G

~37s

If your current phone works well for what you use it for, there is no pressing reason to upgrade purely for 5G. 4G LTE remains fast enough for streaming, video calls, and everyday use and will continue to be supported for many years. If you are due for a phone upgrade anyway, buying a 5G phone now is a reasonable forward-looking choice. 5G coverage continues to expand, and a 5G phone will remain current for longer.

Quick Tip

Quick Tip: 5G phones don't cost more than 4G phones at the same quality level — 5G is now standard across most mid-range and flagship phones. You are unlikely to find a new quality smartphone that is 4G-only.

You have probably heard about 5G — it has been in phone ads and the news for several years. But what does it actually mean, and should you care? This guide cuts through the marketing language and explains 5G in straightforward terms.

In short: 5G is the fifth generation of cellular network technology. Every decade or so, the cellular industry upgrades to a new generation. We went from 3G (which allowed basic mobile internet) to 4G LTE (which enabled smartphone apps and streaming) and now to 5G (which is significantly faster and handles many more devices simultaneously).

For most everyday phone users, 5G means faster downloads and fewer slowdowns in crowded places. Whether 5G is available in your area, and whether your phone supports it, determines how much it affects you.
