What is T-Mobile Home Internet?

If you’re scratching your head and thinking T-Mobile is a cellular network operator, you’re right. T-Mobile has not stepped out of its land but has launched a revolutionary home internet solution that uses its 4G/LTE and 5G cellular networks to provide high-speed internet connectivity throughout your home. 

T-Mobile launched its home internet solution back in early 2021. It was initially a pilot, but the reception and reviews for the service have been overwhelmingly positive, leading the company to launch its 4G/LTE service nationwide by April of that year. 

Fast-forward to 2022, and T-Mobile has continued to innovate with a 5G launch with a bold “Internet Freedom” tagline. T-Mobile Home Internet has continued to go from strength to strength, placing second in the 2022 American Customer Satisfaction Index’s 2022 survey for customer satisfaction

About T-Mobile

T-Mobile is the U.S.’s second-largest mobile network operator with over 110 million subscribers to its services nationwide. Its majority shareholder is the German company, Deutsche Telekom AG, which operates T-Mobile subsidiaries in Europe. 

T-Mobile has over 62% 4G/LTE coverage nationwide. They are also at the forefront of the 5G network rollout, with 40% coverage and climbing. Over 90% of Americans should be able to access T-Mobile’s service which include:

  • Contract and prepaid cell phone plans

Home Internet from the Cellular Network

Mobile internet is different from your conventional cable, fiber, or DSL home internet connection. It is 100% wire-free, relying on the connection to your nearest cell tower for the exchange of data between your home’s devices and the internet. 

Rather than the conventional modem and router, a cellular router is used to access T-Mobile Home Internet. This wireless device uses an inserted SIM card for access to the T-Mobile network and authentication of your data plan. 

Once activated, the router exchanges data with the internet via the cellular connection, just like when you browse on your cellphone. The router also carries a Wi-Fi radio to provide coverage throughout your home. 

T-Mobile Home Internet Services and Cost  

One of T Mobile’s strongest selling points is its simplicity. There’s no need for head-scratching or getting your calculator out. T-Mobile Home Internet has a flat monthly charge of $50 per month. With T Mobile, there are: 

  • No price plans
  • No contracts 
  • No data caps 
  • No throttling

The only discount available is for eligible Magenta MAX customers who pay $30 per month.

T-Mobile Home Internet Speeds

T-Mobile does not have the gigabit per second speeds that fiber boasts, but for a completely wireless internet solution, with enough bandwidth for a household’s-worth of devices, it does a pretty good job. T-Mobile advertises internet speeds of between 33 and a respectable 182 Mbps. 

If you were expecting 5G to be super-fast, T-Mobile is going to disappoint you. Firstly, not all 5G networking offers the high-speed connectivity that requires extremely dense cell tower coverage to achieve, and T-Mobile is still leaning heavily on its regular 4G/LTE coverage. However, what it lacks in speed it makes up for in reliability and performance, and some users have reported speeds of up to 300 Mbps. 

T-Mobile Home Internet Equipment 

With T-Mobile Home Internet, there’s no need to get tangled up with an Ethernet cable. Customers are provided with T-Mobile’s proprietary 5G Wi-Fi Gateway. This is a router that connects to the cellular signal while providing the coverage you need in your home using Wi-Fi. Here are the headline specs of T-Mobile’s Wi-Fi Gateway: 

  • 5G New Radio (5G NR) and 4G/LTE connectivity
  • Wi-Fi 6 router using the latest 4×4 MIMO antenna technology
  • 2 Ethernet ports
  • LCD 
  • Dimensions: 4.73 in x 4.53 in  x 7.52 in (12 cm x 12 cm x 19.1 cm)

The gateways are also mesh network compatible, so you can integrate them with your existing home mesh network. Setup is simple via the dedicated T-Mobile Home Internet smartphone app.

What is Comcast?

Comcast is the largest ISP in the country, with extensive cable internet coverage and a wide range of contract-based service plans. For many homeowners, it is familiar and the obvious choice for reliable home internet services and offers high-speed connectivity. 

However, services and customer experience vary widely, with Comcast historically having a reputation for low customer satisfaction. Many of its services are contracted, with additional service charges and termination fees.

T-Mobile Home Internet vs. Comcast: How Do They Compare? FAQs (Frequently Asked Questions) 

Why are there different upload and download speeds for home internet?

Home internet has a significant disparity between the available upload and download speeds. This is asymmetrical internet connectivity. Most times, the download speeds will be super-fast, while upload speeds drag.

Upload speed is the speed at which data is transferred from your computer to the internet. You are uploading data to the net when you perform activities like emailing, transferring files, using cloud-based programs, or speaking on a VoIP call. You rely on fast download speeds for downloading files, streaming shows, or listening to music online.

For most home activity an asymmetrical internet connection is not noticeable, but if you have high usage and use a VoIP service for phone calls, you may experience some disruption or delay. You can solve this problem by using an ISP with high upload speeds or opting for a high-speed fiber connection which is usually more symmetrical.

Are there cellular home internet alternatives to T-Mobile Home Internet?

T-Mobile’s main competitor is Verizon, which offers a similar 5G home internet package. Verizon launched its mobile home internet solution in 2018 with 4G/LTE connectivity, but it is aggressively rolling out its 5G network and offering a home internet solution with speeds of up to 1 Gbps depending on your location. Here are the highlights of Verizon’s 5G Home plan:

  • Up to 300 Mbps for the basic plan and up to 1 Gbps for the Pro plan
  • No equipment fee, no data caps, no throttling, and no contract
  • Single monthly fee of $70 with a $35 discount for Verizon Unlimited Mobile plan customers
  • Wi-Fi 6 gateway included

Can you change Comcast's home internet plans?

If you are an existing Comcast customer who wants to change your Xfinity plan, you can upgrade or downgrade your plan. Do this instantly online, or by calling customer service which will do this for you. Alternatively, you can visit your local Xfinity store for the agents to change your plan.

What is Wi-Fi 6E?

Wi-Fi 6E (802.11 ax) is the latest version of the Wi-Fi wireless networking technology that you use to distribute your internet connectivity throughout your home. This high-speed, high-performance version of Wi-Fi, launched in February 2022, provides connectivity over three unlicensed frequency bands (tri-band). 

Earlier versions of Wi-Fi used the 2.5 GHz and 5 GHz frequency bands, but Wi-Fi 6E can access new 6 GHz frequency bands for a massive uplift in speed and bandwidth. Wi-Fi 6E also benefits from the latest security standards and authentication technologies. You can learn more about the difference between Wi-Fi 6 and Wi-Fi 6E in our article Wi-Fi 6 vs. Wi-Fi 6E: How Do They Compare?

Are there any other wireless home internet technologies?

If you are in a rural or remote location or living the van life, you have other options for wireless broadband internet:

Fixed wireless internet can provide internet connectivity over long distances by sending a wireless signal carrying the data between two antennas. A broadcast antenna exchanges data with the wired (fiber or copper) backhaul that provides the internet service. Subscribers erect a receiving antenna to access the broadband internet signal and use the internet. 

Satellite internet uses a signal that is broadcast from Low Earth Orbit (LEO) satellites. Subscribers to a satellite internet service use antennas to capture the signal and send and receive data. Satellite internet is usually expensive. The satellite signal is weakened as it passes through the ionosphere, leading to low latency and slower speeds. Starlink is a novel satellite internet solution that has achieved low-latency broadband internet connectivity at a competitive price.
