T-Mobile Launches New Business Smartphone Plan Lineup – Including Support For 5G Network Slicing

T-Mobile has rolled out a new business smartphone plan lineup, replacing the previous "Business Unlimited" lineup.

There are three new plans in the lineup: SuperMobile, ProMobile, and CoreMobile. These plans are now available for sole proprietors, small businesses, and enterprise customers with T-Mobile business accounts.

In T-Mobile's press release, they are only touting the top-tier SuperMobile plan, which offers unique features not available on any other business smartphone plan - including 5G network slicing and 5G privacy features that are not yet widely deployed. This plan is designed to leverage T-Mobile's advanced 5G network.

So are these new plans any good for mobile users living, working, or traveling in vans, boats, and RVs? Let's dig into the details...

T-Mobile Business “Mobile” Plans

Here is a rundown of the core features of the new lineup.

First, the pricing. Here's the cost for 1-4 lines, including the autopay discount and T-Mobile's longstanding policy of providing the third line for free via monthly bill credits:

• SuperMobile: $95 - single line (2 - $160 / 3- $160 / 4- $195)
• ProMobile: $80 - single line (2- $140 / 3- $140 / 4-  $165)
• CoreMobile: $60 - single line (2 -$90  /3 - $90 /4- $105)

All these plans include T-Mobile's 5-year price guarantee - so the price is not subject to sudden increases anytime soon.

Additionally, consistent with T-Mobile's recent policy changes, these plans do NOT include taxes and fees. Currently, T-Mobile adds $3.99 to most lines, plus required federal and local taxes and surcharges.

Data Terms

Some data terms have changed compared to the previous Business Unlimited plans, with some positive and some negative changes. The negative changes involve lower international data limits, and the base CoreMobile plan has less premium data and hotspot data, but is also $10/month less expensive.

Premium Data

In the new lineup, only the SuperMobile plan has unlimited premium data with no deprioritization.

The ProMobile plan offers 200GB of premium data, while the CoreMobile plan provides only 50GB of premium data before being deprioritized relative to other traffic on T-Mobile's network.

High Speed Hotspot Data

Mobile hotspot allowances have increased for the top two plans and significantly reduced for the CoreMobile plan. Here are the high-speed hotspot amounts with the new plans:

• SuperMobile: 300GB 
• ProMobile: 200GB 
• CoreMobile: 5GB

The previous top-tier Business Unlimited Edge plan had 250GB of hotspot, so a 50GB increase is nice. Note that after the allotments are used up, hotspot speeds are reduced to 600kbps for the remainder of the month. 

T-Mobile also notes that accounts with more than six lines can add additional hotspot data with a per-line additional cost.

Video Streaming

Video streaming throttles are up to 4K UHD for the SuperMobile plan and up to HD (1080p) for the ProMobile plan.

The base CoreMobile plan is limited to SD video, but it can be upgraded to HD video with the purchase of a $3 day pass.

The T-Mobile fine print states that customers must manually enable HD/UHD streaming, even on the top two plans, indicating that the plans only support SD until higher video speeds are enabled.

International Data

One of the significant downsides of the new plans is reduced international data allotments. Here are what the new plans support:

• SuperMobile: 5GB high-speed data in Canada and Mexico and in 215+ other countries
• ProMobile: 5GB high-speed data in Canada, Mexico, and 11 other countries
• CoreMobile: 5GB high-speed data in Canada, Mexico, and 11 other countries

The previous Unlimited Edge plan included 15GB of data for Canada and Mexico. In comparison, the current consumer postpaid Experience Beyond plan, available to both consumers and businesses, offers 30GB of data for Canada and Mexico, as well as 15GB of data for 215+ other countries. 

These plans are not ideal for international travelers compared to other T-Mobile options. However, day passes of up to 15GB of data are available for purchase.

Other Features And No Perks

The SuperMobile and ProMobile plans both come with T-Satellite included - this is T-Mobile's partnership with Starlink to provide limited satellite connectivity in T-Mobile cellular dead zones. CoreMobile customers can add the feature for another $15/month per line.

On the downside, the new plans do not come with any perks. The previous lineup included features such as a Microsoft 365 account, Apple TV+, and ViX Premium. These new plans do not provide any similar bonus features.

However, T-Mobile is promoting a significant new perk available only with the SuperMobile plan: access to T-Mobile's new "business network slice" for enhanced priority on T-Mobile's network.

But just what is a network slice, and why should you care?

Network Slicing on SuperMobile

Network slicing is a 5G-only capability designed to address many of the limitations of the basic network priority system used for LTE and 5G non-standalone (NSA) networks. 5G NSA networks combine LTE and 5G signal bands together - and are held back from some advanced 5G features, like network slicing, by the LTE part of the connection.

For more on the difference between 5G SA and 5G NSA and other cellular technologies like network slicing, see our 2025 Cellular Industry Update.

In a nutshell, network slicing creates a virtual network that allows certain types of data and applications to bypass congestion on the regular network - it's not merely greater network priority, it's a dedicated fast lane. Unlike the standard priority system used today, network slicing allows much more control over what kind of data gets access to the network slice.

And one thing to be clear on is that not every bit of data will get access to that congestion-free network slice - data can be sliced by application, not just by device. 

The business network slice that T-Mobile created and included with the SuperMobile plan is designed to give business data and applications access to this fast lane. T-Mobile puts it this way:

Network slicing creates an optimized environment for your business traffic. It continuously adjusts network resources in real time to help ensure reliable performance—whether completing file transfers from the airport before your flight leaves, keeping retail apps running smoothly on Black Friday, or supporting a major presentation without interruptions on your video call... [It] dynamically optimizes bandwidth and allocates network resources for your critical apps—like video calls and large file transfers—and adapts to your use and changing conditions, even in data-intensive use cases, when your team's use spikes, or other network traffic increases.​

T-Mobile has not disclosed the exact enforcement rules it is using to decide what traffic gets to utilize the business slice, but the marketing and fine print suggest that business-oriented apps like video conferencing, cloud services, and file transfers will utilize the prioritized slice.

It's safe to assume general consumer traffic (like Netflix/Prime streaming) won’t be able to use the slice and will be treated as regular traffic.

The SuperMobile plan's business network slice also comes with some additional limitations, as described in the plan's fine print:

Slice features available on our 5G standalone network; not available while roaming, via satellite, or while tethering. Slice features (data prioritization and latency optimization) available in areas of Ultra Capacity 5G coverage with capable device and 5G Standalone settings. Coverage not available in some areas.

The exclusion of hotspot/tethering data from the slice is a big caveat to be aware of.

SuperMobile Security Features

T-Mobile is also offering several security-related features on this plan, including one that no other U.S. carrier has advertised so far — the Subscription Concealed Identifier (SUCI).

In older networks (2G through LTE), phones revealed a permanent ID called the IMSI (International Mobile Subscriber Identity) when they connected to the tower. This identifier, stored on the SIM or eSIM, was essential for registration and billing — but it could also be intercepted by so-called IMSI-catchers, enabling malicious actors to track or even impersonate users.

With the SuperMobile plan on 5G, that exposure changes. The permanent identifier is now called a SUPI (Subscription Permanent Identifier), and before it ever leaves your phone, it’s encrypted into a one-time-use SUCI.

Think of this like using a disposable virtual credit card number that’s tied to your real card; it lets the network authenticate you without ever revealing your permanent number.

This means devices on SuperMobile are much harder to track or impersonate, improving both privacy and enterprise security. While SUCI is part of the global 5G standard, and may be used in some cases by other carriers, T-Mobile is the first U.S. carrier to spotlight it as a feature in a business plan.

SuperMobile also comes with T-Mobile's other premium security addons as standard, including an app-based VPN called Threat Protect, and ScamShield Premium, designed to foil scam calls/texts.

Concluding Thoughts

T-Mobile was once a distant third behind AT&T and Verizon in network technology, but its acquisition of Sprint has allowed it to leap far ahead in terms of 5G technology.

T-Mobile is capitalizing on this lead by taking advantage of its advanced 5G network and offering features not widely available anywhere else, like network slicing. 

While AT&T and Verizon have tested network slicing, and Verizon has some limited slicing deployments, T-Mobile is the first to launch it commercially nationwide for business customers, following its earlier provisioning of network slicing to first responder customers last April. Even though T-Mobile is first to the market, expect that most business (and many other) plans in the future will offer some form of network slicing as well.

While network slicing is an exciting new feature enabled by the advancement of cellular 5G networks, the new business plan lineup is unfortunately downgraded in some areas, notably international data and bonus perks. Those who want the perks and more international data should consider the Experience Beyond For Business plan, which is only available in T-Mobile stores, or a T-Mobile consumer Experience plan.

Still, with our previous Top Pick T-Mobile Business smartphone plan now retired (Business Unlimited Edge), the SuperMobile plan will take its place in our Top Picks, alongside the Experience Beyond For Business plan. SuperMobile is an especially attractive smartphone plan for those who require a lot of hotspot data and need consistent, fast network performance for their business applications on a smartphone.
