What are 5G smartphones and how do they work?
5G smartphones are mobile devices that support 5G wireless networks, and they work by connecting to 5G cellular towers using specialized 5G modems and antennas. You use these phones just like 4G ones, but they connect to faster and more efficient 5G signals, which use higher frequency bands (including mmWave and sub-6GHz) to move more data at higher speeds and lower latency.
These phones include 5G-compatible chipsets (like Qualcomm Snapdragon or MediaTek Dimensity), which handle data processing and signal conversion. Most 5G smartphones can switch between 5G and older networks (4G, 3G), so you stay connected when 5G isn’t available.
Phone makers also include advanced cooling systems and power management features, since 5G chips use more energy and generate more heat. You need a 5G SIM card and a 5G mobile plan to activate full 5G functions.
Around 100%% of smartphones on the market support 5G connectivity (among smartphones released in 2022 and later).
The best available 5G smartphones (with the highest overall score) are as follows:

Can you use a 4G SIM in a 5G phone?
Yes, you can use a 4G SIM in a 5G phone. The phone will detect the SIM and connect to 4G networks, but not 5G. You can still use all standard features like calls, texts, and mobile data on 4G.
5G phones support older network generations (4G, 3G, 2G), so you don't need a new SIM to use your phone. However, your data speeds will depend on the 4G network, not on the phone’s 5G capability. If you want to access 5G speeds, you need a 5G-enabled SIM and a 5G mobile plan. Some carriers also require activation of 5G service, which depends on your plan type and location.
