The AT&T and T-Mobile Note 10 Plus 5G will not work on the fastest 5G networks

There will be several versions of the Note 10 Plus 5G in the telephone operators.

The 5G version of Galaxy Note 10 Plus reach the four largest telephone operators in the United States, but not be without sacrifices. Verizon offer the Note 10 Plus 5G first at $ 1,300, and AT&T, T-Mobile and Sprint said they will have their own plans to offer the phone later this year.

But the versions of these phones and the status of 5G technology in the United States will make the cell phone launch a little more complicated than previously thought.

While Verizon offers the Note 10 Plus 5G with the Qualcomm X50 modem that is able to take advantage of the 5G millimeter wave network currently deployed in nine cities in the United States (plans to cover more than 30 cities in the country for purposes of ao), the phone variants offered by AT&T and T-Mobile will not work with millimeter waves.

Instead, the versions of these operators will feature the Qualcomm X55 modem and are compatible with a non-5G version known as sub-6. Although this allows cell phones to take advantage of the wide range of 5G networks that At & T and T-Mobile have planned to deploy in the coming months, they will not work with millimeter wave networks that are super-speed and that both operators have already deployed throughout the United States.

The 5G millimeter wave technology is excellent for ultrafast speeds, but its coverage is limited to some sections of cities. This kind of 5G technology also makes it difficult for you to access the interior of buildings and their higher frequencies tend to cause problems when used in higher temperatures. The 5G low band technology, on the other hand, does not have a superfast speed, but it offers a wider coverage area than 5G of millimeter waves and will be able to function better within buildings. A third version of 5G, known as a midband spectrum, is like a midpoint that offers faster speeds than low band and better coverage than millimeter waves.

The AT&T Note 10 Plus 5G phone will only work in the low band spectrum. While the Note 10 Plus 5G work with its 600Mhz low band spectrum and also be compatible with the 2.5Ghz mid band spectrum.

Sprint currently uses the 2.5Ghz band for its 5G network. T-Mobile, of course, is in the process of completing its fusin with sprint, which will give you access to that spectrum.

Sprint refused to comment on how to be present in the version of Note 10 Plus 5G to sell.

The company sells the Galaxy S10 5G with the Qualcomm X50 modem that is compatible with the 2.5Ghz midband and is also capable of using the T-Mobile millimeter wave network. If your version of the Note follows Verizon's steps and uses the same X50 chip, there may be two versions of the Note 10 Plus 5G with different experiences on the T-Mobile network.

The Sprint version may be compatible with the 2.5Ghz middle band and the T-Mobile superfast network, while the T-Mobile version will be compatible with the 600Mhz band that will have coverage in most of the country and the 2.5Ghz band of Sprint.

In short, maybe now is not the best time to buy a 5G phone.
