As expected, the entire iPhone 12 lineup is compatible with faster 5G networks, but Apple's website confirms that support for high-frequency mmWave bands is limited to models sold in the United States. This includes compatibility with Verizon's new 5G Ultra Wideband network, which as of today is available in 55 cities across the country.
mmWave is supported on all iPhone 12 models sold in the United States, ranging from the iPhone 12 mini to the iPhone 12 Pro Max. iPhone 12 models sold in all other countries and regions are limited to sub-6GHz bands for 5G.
mmWave is a set of 5G frequencies that promise ultra-fast speeds at short distances, making it best suited for dense urban areas. By comparison, sub-6GHz 5G is generally slower than mmWave, but the signals travel further, better serving suburban and rural areas. In most countries that offer 5G, sub-6GHz networks are more common.
Apple says iPhone 12 models support more 5G bands than any other smartphone, and the devices can automatically adjust to LTE when necessary to save battery life, such as when updates are taking place in the background.
