If you use a modern iPhone on T-Mobile’s cellular network, there’s a good chance you’ll see the “5G UC” icon instead of “5G” on the status bar. It tells you about your cellular connection.
5G UC stands for “5G Ultra Capacity”
This icon indicates that you are connected to a type of 5G network, and you will only see it on iPhones with 5G support. (By the end of 2021, only iPhone 12 and iPhone 13 phones have 5G support.)
Specifically, this icon is displayed when you are connected to T-Mobile’s “Ultra Capacity” 5G network. Icon Began to appear On iPhones in mid-September 2021.
What is 5G Ultra Capacity?
5G is more complex than you think, and different types of 5G offer different speeds.
T-Mobile divides its 5G network into two types of 5G. The “5G Extension Range” is a type of 5G that will be almost as fast as G 4G LTE and blankets in most parts of the country, including in the less developed rural areas. “5G Ultra Capacity” is a high speed 5G that promises speeds faster than 4G LTE.
To differentiate between the two, you’ll see the 5G UC icon when you’re connected to T-Mobile’s better, faster 5G network. When you connect to T-Mobile’s slow “extended range” 5G network, you’ll only see a standard 5G icon.
Technically, 5G UC indicates that you are connected to either midband or mmWave 5G. For T-Mobile, you are probably connected to the midband 5G, as it forms a large part of T-Mobile’s high-speed 5G network. The standard “5G” logo without UC indicates that you are using low band 5G.
You can see where T-Mobile’s 5G UC network is available on T-Mobile’s coverage map website. The map distinguishes between the two types of 5G, 5G UC network with color dark magenta.
What about other cellular carriers and Android phones?
By September 2021, the 5G UC logo will only appear on iPhones connected to T-Mobile’s network.
If you’re using an iPhone 12 or iPhone 13 (or iPhone 12 Pro or iPhone 13 Pro), if you’re using another cellular carrier like AT&T or Verizon, you’ll need a 5GU The C logo will not be visible.
If you’re using a 5G enabled Android phone on T-Mobile’s network, you won’t even see the 5G UC logo. (However, this may change in the future.)
What do “5G +,” “5G UW,” and “5G E” mean?
This is not the first letter we have seen in the 5G logo. Both “5G +” and “5G UW” are similar to “5G UC” and indicate faster 5G than standard low-band networks over long range.
The “5G +” status icon appears when your iPhone is connected to AT & T’s 5G mm view network.
The “5G UW” status icon indicates that your iPhone is connected to Verizon’s Ultra Wide Band 5G network.
There is also 5G E, the marketing term AT&T applies to its older 4G LTE network. 5G E was not real 5G. this is true. Sprint sued AT&T back in 2019, accusing the company of misleading customers.
5G UC, 5G +, and 5G UW all indicate good, fast 5G signals. (This is different from the 5G E, which was worse than seeing the 5G icon and not the 5G at all.)
Will these logos be seen outside the United States?
Apple’s official support website discusses terms such as 5G UC, 5G +, and 5G UW without specific carriers, so you can see these logos on other cellular carriers outside the United States. However, if you only see the 5G logo, it does not indicate that you are necessarily using a slower low band 5G. Your cellular carrier is not displaying such a logo.
