5G networks have slowly started rolling out worldwide. All three major carriers in the US—AT&T, T-Mobile, and Verizon—claim that they have started rolling out nationwide 5G networks. Now, Verizon's “Nationwide 5G” network has started becoming available on select Samsung smartphones.
The Galaxy A51 5G UW, Galaxy A71 5G UW, Galaxy Note 20 5G, Galaxy Note 20 Ultra 5G, Galaxy S20 5G UW, Galaxy S20+ 5G, and the Galaxy S20 Ultra 5G can now use Verizon's low-band 5G network in the US. Although these devices have supported 5G networks from the start, they needed software updates to get access to Verizon's 5G network. Most of the smartphones mentioned here have now started receiving the required software updates with September 2020 security patch.
Right now, all of Verizon's monthly and prepaid plans come with access to its 5G network. So, if you have any of the devices mentioned above, you can start using 5G on it after installing the latest update. However, 5G networks don't automatically mean faster download and upload speeds. Depending on your location, you might experience speeds slower than typical 4G networks. Phones might also consume more power while using 5G networks, so battery life could be shorter.
