T-Mobile’s 5G Home Internet service, a staple since its rollout years ago, has taken a leap forward with a new firmware update for its flagship G4AR gateway, enabling 5G Standalone (SA) connectivity. Unveiled last week, the update to version 1.00.13—exclusive so far to the G4AR modem—frees the device from its reliance on an LTE “anchor” for uploads, allowing full 5G connections for both download and upload. Spotted over the weekend by users on the r/tmobileisp subreddit via The Mobile Report, this shift promises faster speeds, lower latency, and broader reach for the Un-carrier’s top-tier Amplified and All-In plan customers, who typically receive the G4AR, while Rely plan subscribers stick with older models like the KVD21 or 5688W.
This is a lot of technical talk, but the short version of it is this update will allow faster uploads and improved performance for T-Mobile’s 5G Home Internet customers.
Until now, T-Mobile’s gateways—including the G4AR—leaned on 5G for downloads but tethered uploads to LTE, sidelining homes in LTE-dead zones from service. The 1.00.13 update, detailed on T-Mobile’s support page, ditches that hybrid setup, letting the G4AR tap 5G exclusively. Beyond the usual “bug fixes” and “stability improvements,” 5G SA unlocks ultra-low latency and upload speeds far surpassing LTE’s limits—think 50-100 Mbps versus 3-10 Mbps in real-world tests. Older gateways like the G4SE, KVD21, and 5688W await similar upgrades, though T-Mobile’s has not announced any news on this.
The upgrade isn’t just about speed—5G SA lays groundwork for advanced features. T-Mobile’s “T-Priority” network slicing, launched for first responders, could extend to Home Internet, offering priority bandwidth in crowded areas as a premium perk. Carrier Aggregation, merging multiple 5G signals, is next, with T-Mobile touting lab speeds up to 6 Gbps—beyond the G4AR’s current ceiling but a hint of future gains.
T-Mobile’s Home Internet, serving over 5 million homes by Q4 2024, has long reserved the G4AR—boasting four SMA antenna ports and Wi-Fi 6—for its priciest tiers ($60-$70/month). The 5G SA milestone, years in the making (hackers forced it on unsupported units pre-2025), aligns with a T-Life app update teased by a source, set to detail 5G SA versus NSA band connections—enhancing visibility beyond the app’s current basics. “Finally, T-Mobile’s catching up to the hype,” an X user quipped, nodding to DIY 5G SA fans who’ve long praised its edge.
With no manual update option T-Mobile users will have to wait but should see it soon, For now, it’s G4AR-only, but T-Mobile’s signaling: 5G’s future is standalone, and it’s here.
