What is 5G?

5G is the fifth generation of cellular wireless technology. It can support faster data transfers, shorter response times, and more connected devices than earlier generations. The experience on your phone depends on the carrier, coverage, spectrum, device, and network conditions.

What Is the Difference Between 4G LTE and 5G?

4G LTE and 5G are generations of mobile network technology. A compatible device can use 5G where the carrier offers it. Coverage and speed can vary within the same city, so compare the networks at the locations where you actually use your phone. See the FCC’s explanation of the mobile technologies on its coverage map.

Do You Need a 5G Phone?

Check that your phone supports the carrier’s 5G network and that your plan includes access. An older 4G LTE phone can use compatible LTE coverage where it is available. Consider upgrading if a new phone solves a problem you have, such as poor performance on a busy commute or limited software support. For plan comparisons, see our Mint Mobile guide and Verizon pros and cons.

Home Internet and Wi-Fi

Wi-Fi connects devices to a local router. A home internet provider can use a 5G cellular connection to serve a gateway, and the gateway can still use Wi-Fi to reach your devices. Compare fixed wireless and wired internet at your address using typical download and upload speeds, latency, fees, and equipment.

How to Check Coverage Before You Switch

1. Look up home, work, and the routes you use on your carrier’s map.
2. Check the phone model and plan before you buy. Confirm that the carrier supports the device.
3. When possible, test the connection in the places and at the times you need it. Maps are estimates, and indoor reception can differ from outdoor coverage.

Radiofrequency Exposure and Health

The World Health Organization summarizes research on radiofrequency exposure from mobile networks and explains how exposure limits are set. See WHO’s 5G and health overview.
