“Why is 5G so slow?” Why is my 5G so slow? The first and most significant factor is that low-band carrier frequencies have been used to power the vast majority of 5G carrier rollouts in the US, primarily those from AT&T and, to a lesser extent, T-Mobile. Thus T-Mobile revvl 6 Pro 5g also asks this question.

“What’s going on?” you wonder. “Wasn’t 5G supposed to be far faster than 4G?” Yes, it was. 5G was intended to be the supercharged engine that would power our future mobile networks. In truth, it’s been a huge letdown for many of us.

It can be difficult to figure out why. The carriers won’t explain why their networks aren’t performing as promised. Fortunately, we’re here to explain why 5G may disappoint you and why you shouldn’t give up hope just yet.

Why is 5G so Slow: Is this 5G?

5G is sometimes portrayed as a monolithic technology, with a single vehicle carrying all mobile data requirements. In actuality, it is far from it. Not only do the three major US carriers each provide their own varieties of 5G services, but there are also multiple wireless frequencies needed to broadcast those services across each network.

Our guide to C-Band 5G, which we’ll go over in more detail later, includes a detailed look at how each carrier uses those frequencies. But the crucial point to note here is that there are relatively few impediments to a carrier placing a 5G logo on top of its smartphone screens, even if it does not deserve to.

Why is 5G so Slow

In reality, AT&T attempted to be the first in the US to offer “5G” services by renaming what were essentially unchanged 4G LTE services as “5G E.” As one might assume, the perplexing, dubious advertising move did not go down well. In fact, AT&T was forced to backtrack on the whole thing and pay a monetary settlement after Sprint (now owned by T-Mobile) filed a false advertising case against it.

Why is my 5G so Slow: 5G…Technically

So, why are some 5G connections so slow? The first and most crucial factor is the use of low-band carrier frequencies by the far-reaching 5G signals that have powered the majority of US carrier rollouts, most notably AT&T and, to a lesser extent, T-Mobile. Thus T-Mobile Revvl 6 Pro 5g users often face this issue. These frequencies (850 MHz for AT&T and 600 MHz for T-Mobile’s early efforts) can travel for kilometers from their towers. The disadvantage is that their real-world speed capacities are typically less than 100 Mbps, which is comparable to what a strong 4G LTE connection can already do.

Another key factor is the widespread usage of Dynamic Signal Sharing (DSS). This technology enables carriers such as AT&T and Verizon to use the same radio bands for 4G, LTE, and 5G coverage. The benefit is that some currently used components and frequency ranges can hasten the rollout of 5G by obviating the requirement for new infrastructure and spectrum license purchases.

Unfortunately, while the 5G side of DSS is true 5G in certain ways, its actual performance is “equivalent to [its] award-winning 4G LTE,” according to Verizon. Congestion, technology limitations, and the continued reliance on low-band frequencies are a few of the factors contributing to this.

Simply put, the most common varieties of 5G currently available in the US all fall into the category of 5G services that are no faster than 4G and offer little in terms of comparative benefits other than being broadly available.

Why is my 5G so Slow: Is fast 5G even available in the United States?

It not only exists, but we are finally entering an era in which a large percentage of the country, rather than simply the fortunate few in heavily populated urban areas, will benefit from it.

Until recently, the only 5G rollouts that actually topped the speed and capacity of 4G were those that used either mid-band or high-band frequencies.

T-Mobile performed exceptionally well in the early 5G race, thanks in large part to its choice to acquire Sprint. That acquisition provided access to Sprint’s spectrum licenses and embryonic tower network, both of which used the 2.5 GHz band. This is a mid-band frequency, a coverage segment considered a sweet spot for 5G services because it combines excellent speeds with adequate range and penetration to enable coverage regions still measured in square miles.

Verizon and AT&T, on the other hand, have relied nearly entirely on high-band deployments until their recent C-Band launches. Verizon’s fastest 5G networks have traditionally relied on the millimeter-wavelength frequency bands of 28 GHz and 39 GHz. These higher frequencies enabled download speeds that easily exceeded 1 Gbps, or more than ten times what its DSS-based network could provide. The disadvantage is that those speeds were only available within a range of “1,500 feet without impediments,” according to Verizon.

Why is 5G so Slow: So, when can I expect speedy 5G to arrive?


If you’re a T-Mobile user, especially using the T-mobile revvl 6 Pro 5g, you’ve undoubtedly already noticed benefits since the firm virtually completed its statewide 5G deployment in late 2021. According to Opensignal, its 2.5 GHz service offers a countrywide average of roughly 150 Mbps, with speeds that can easily exceed 400 Mbps or more in highly covered locations. Both of these metrics should rise as the carrier continues to “densify” its network with new technology and equipment.


For Verizon Wireless consumers, the wait is either gone or will be soon. The firm’s C-Band debuts run between 3.7 GHz and 3.98 GHz, making them in the same advantageous range as T-Mobile.
Early tests from our sister site CNET revealed speeds of up to 1.4 Gbps under ideal conditions, with 400 Mbps available over a broader area and 90 Mbps achievable even deep under an underground garage.

Verizon states that its initial rollout (which was obliged to skip US airports due to interference issues) comprises 46 “major metro areas.” Each rollout is also measured in square miles, as opposed to prior high-band launches, which were lucky to reach a city block. The company aims to continue expanding its markets in the future.


AT&T customers may have the longest wait of the “Big Three” carriers. C-Band’s first rollout included only eight cities. However, it, like Verizon, has lofty goals for the future, stating that its new 5G spectrum will cover 200 million people by the end of 2023. Unfortunately, it has not offered any information on where these potential clients might be located. However, according to a recent deal signed by AT&T, Verizon, and the Federal Aviation Administration, US airports may soon have access to the new technology as it is carefully built out across air traffic centers in a manner that will not disrupt US commercial flights.

Hopefully, this article has educated you on why your 5G services may not be meeting your expectations right now, and how much hope you should have that this will change in the near future. I promise that 5G will transform the way we use our mobile devices, although it may take a little longer than you expected.


How can I improve the speed of my 5G?

SINR is a metric used in 4G, LTE, and 5G networks to measure signal quality. Increasing your SINR might have a significant influence on your connection speeds. The easiest option to improve SINR is to utilize a directed outdoor antenna, either connected to a signal booster or directly to an LTE or 5G hotspot.

Why is my 5G so slow? – iPhone Users

  1. Check for and install any available software updates – this will guarantee that you are using the most recent version of iOS, which may help with speed difficulties.
  2. Restart your device – this can frequently help repair minor technical issues.

Is Verizon’s 5G as bad as LTE?

Low-band 5G has the greatest signal reach but only 20% better speeds than 4G LTE. Mid-band 5G is approximately six times quicker than 4G LTE and provides an excellent balance of coverage and performance.

Should I use LTE or 5G Auto?

Select how your iPhone connects to the 5G network, which can impact battery life. Smart Data Mode is enabled by 5G Auto. Your iPhone automatically switches to LTE when 5G speeds don’t significantly improve the user experience, conserving battery life. When the 5G network is enabled, it will always use it.

What influences 5G speed?

In addition to where you are when you connect to the network, additional factors that affect your actual 5G speeds include the hardware you’re using, the network’s speed, how many users are sharing the 20+ GB/s, and the type of interference that exists between you and the 5G cell.

Why does my phone display LTE rather than 5G?

Check that your location has 5G coverage. Yes, there is 5G everywhere, but the network still has enormous gaps, so coverage is not guaranteed. Your 5G phone will always detect a signal and connect if it is 5G-capable. If it’s not accessible, your phone will default to LTE or 4G.

Why is my iPhone slow when connected to full service?

Why is my iPhone running so slowly? The most likely cause of your iPhone’s slowness is a lack of storage space, a dying battery, or the use of outdated apps and software. Resolvable performance problems may also be to blame for a sluggish iPhone. iPhones, like any other electrical item, slow down with age.
