T-Mobile just placed a hard speed limit on its lowest-priced 5G home internet offering. New customers signing up for the Rely plan will see downloads capped at 354 Mbps. The change marks the first artificial speed restriction the carrier has imposed on a home broadband product in more than a decade.
Previously the plan advertised typical speeds from 170 to 498 Mbps. Now it tops out at 354 Mbps. Higher-tier Amplified and All-In plans remain uncapped with typical downloads listed between 170 and 498 Mbps. Existing Rely customers keep their original service terms.
All three plans rose $5 per month in list price. An offsetting $5 increase in the autopay discount leaves the effective cost unchanged for most new subscribers who also carry a T-Mobile voice line. The Rely plan starts at $35 monthly after discounts. Amplified and All-In sit at $45 and $55.
T-Mobile’s balancing act between growth and network strain
The carrier’s fixed wireless access business has expanded rapidly. T-Mobile reached nearly 8.5 million 5G home internet customers by the end of 2025, adding almost two million connections that year alone, according to an Inside Towers report. Company executives now target 15 million 5G broadband subscribers by 2030, up from an earlier 12 million goal by 2028. That ambition sits atop a cellular network already serving more than 120 million mobile customers.
Network management has become unavoidable. T-Mobile’s official policy states that during congestion, home internet customers may notice slower speeds than mobile users. Those exceeding 1.2 TB of data in a billing cycle face further reduction as “Heavy Data Users” prioritized last on the network. The threshold first applied to new customers in January 2024 before expanding to everyone months later. Light Reading detailed the rollout.
But the new Rely cap operates differently. It is not a congestion-based throttle. It is a permanent artificial ceiling written into the plan itself. T-Mobile’s updated FAQ confirms Rely customers now receive typical downloads between 170 and 354 Mbps, with maximums not exceeding 354 Mbps. Higher plans continue to promise the fastest speeds available at the location.
Critics see tiered performance as a departure from the carrier’s early home internet marketing. When T-Mobile launched the service it emphasized simplicity, unlimited data and strong speeds without contracts. The 1.2 TB deprioritization already drew complaints from heavy users who reported noticeable slowdowns at month end. YouTube reviews from early 2026, including one titled “Is T Mobile 5G Home Internet Good in 2026,” captured users experiencing drops to 10-20 Mbps in congested areas after crossing the threshold.
Still, the majority of households stay well below 1.2 TB. Average U.S. broadband consumption hovers around 500-600 GB monthly. T-Mobile has repeatedly said only a small fraction of customers will feel the effects of its heavy user policy. The Rely cap appears aimed at a different goal: segmenting the customer base by willingness to pay for peak performance.
And the distinction matters. Households streaming 4K video on multiple screens or backing up large files to the cloud can push past 354 Mbps easily. Gamers and remote workers often notice the gap between 350 Mbps and 500-plus. By reserving the highest speeds for pricier plans, T-Mobile protects network resources while extracting more revenue from power users.
The move also reflects maturing economics. Early fixed wireless access relied on spare capacity in 2.5 GHz spectrum. As subscriber numbers climb, that spare capacity shrinks. T-Mobile’s own filings and earnings calls highlight “fallow” spectrum as the foundation for growth. Executives describe the 15 million subscriber target as conservative. Yet each additional home connection competes for airtime with smartphones on the same towers.
Competitors face similar pressures. Verizon and AT&T both apply deprioritization after high data thresholds on their fixed wireless offerings. Cable providers continue to dominate with multi-gigabit wired service in urban areas, but T-Mobile’s wireless option remains the primary broadband choice for millions in rural and suburban locations where fiber never arrived.
Customer reaction on social platforms and forums has been mixed. Some view the Rely plan as sufficient for everyday use. Others see the cap as evidence that the unlimited promise comes with asterisks. One recent post from The Mobile Report on X noted the change and linked to analysis showing it as the first plan-specific speed limit in years.
T-Mobile itself frames the update as product differentiation. Its website now lists Rely for “essentials” while promoting Amplified and All-In for households with more devices and higher demands. The 5-year price guarantee applies across plans, shielding customers from rate hikes on the monthly access fee. Taxes, equipment upgrades and network management practices remain excluded.
What comes next is unclear. The carrier has not signaled plans to cap its other home internet tiers. Yet the introduction of one artificial limit raises the possibility of further segmentation. Industry observers will watch whether download figures on Rely subscriptions begin to cluster near the new ceiling or whether real-world performance falls short even of that.
For now the policy change sends a direct message. T-Mobile’s home internet service is no longer a single undifferentiated offering. It is a ladder of performance levels with corresponding prices. The cheapest rung simply does not reach as high as it once did.
