Which MVNOs use the T-Mobile network?

Last updated .

Short answer

Assurance Wireless, Astound Mobile, Bark Phone, Google Fi Wireless, Helium Mobile, Kroger Wireless, Metro by T-Mobile, Mint Mobile, Optimum Mobile, SpeedTalk Mobile, StandUp Wireless, Tello, and Ultra Mobile run exclusively on the T-Mobile network. Boost Mobile, Gen Mobile, Red Pocket Mobile, and US Mobile also offer T-Mobile service alongside other networks — which one you get depends on the SIM or plan you buy. Coverage follows T-Mobile; price, plan, and customer service do not.

Brands that offer T-Mobile among several networks

For these brands, "runs on T-Mobile" is true of some SIMs and plans but not all. Confirm the specific network at purchase or activation before you rely on its coverage.

Boost Mobile — EchoStar Corporation
EchoStar brand, now a hybrid MNO: Boost’s own 5G core connects to AT&T’s cell sites for primary coverage, with continued access to the T-Mobile network. EchoStar sold its 3.45 GHz and 600 MHz spectrum to AT&T (about $23 billion, announced August 26, 2025; AT&T closed the purchase in July 2026) and no longer operates a radio network of its own. Networks: AT&T, T-Mobile. Official site (opens in a new tab) · Verified August 29, 2026.
Gen Mobile — Boost SubscriberCo L.L.C. (EchoStar Corporation)
EchoStar-owned budget brand whose network depends on the SIM/plan: its “Sky” variant is AT&T-compatible, “Rose” is T-Mobile-compatible, and “Orange” rides Boost — which itself now runs primarily on AT&T. Networks: AT&T, T-Mobile. Official site (opens in a new tab) · Verified August 8, 2026.
Red Pocket Mobile
Offers SIMs for multiple major networks; you choose the network at purchase. Networks: Verizon, AT&T, T-Mobile. Official site (opens in a new tab) · Verified September 12, 2026.
US Mobile
Lets you pick a network: Verizon (“Warp”), T-Mobile (“Light Speed”), or AT&T (“Dark Star”). Choose the one with the best coverage where you live. Networks: Verizon, T-Mobile, AT&T. Official site (opens in a new tab) · Verified August 29, 2026.

What riding on T-Mobile actually gets you

The host network decides your coverage footprint — which towers and bands your phone can use. It does not decide your price, your plan structure, or your customer service, which is why two brands on T-Mobile can feel completely different to live with.

Three things routinely differ from T-Mobile's own postpaid plans: deprioritization (on a busy cell site, MVNO traffic yields to the carrier's own customers, so peak-hour speeds drop first), feature limits (hotspot allowances, international roaming, and sometimes which 5G bands are enabled), and device support (an older phone may not carry every band the network uses). None of these show up on a coverage map.

Limitations & caveats

  • This page identifies host networks only — it is not a coverage or availability check for your address.
  • On congested cell sites, MVNO traffic may be deprioritized behind T-Mobile's own postpaid customers.
  • Host-network relationships change when brands are acquired or switch carriers; each entry is dated separately.

Frequently asked questions

Do MVNOs on T-Mobile get the same coverage as T-Mobile?

The coverage footprint is T-Mobile's, but the experience is not identical. When a cell site is congested, MVNO traffic is typically deprioritized behind T-Mobile's own postpaid customers, so peak-time speeds can be slower. Some plans also limit hotspot data, international roaming, or which 5G bands you can use.

Is a brand on this page guaranteed to work at my address?

No. This page answers which network a brand resells — it is not a coverage check. Check T-Mobile's own coverage map for the places you actually live, work, and commute, and remember that modeled maps describe outdoor signal, not indoor reception.

Why do some brands appear on more than one network's page?

Boost Mobile, Gen Mobile, Red Pocket Mobile, and US Mobile operate on several carrier networks. Which one you get depends on the SIM or plan you buy and sometimes on your area, so confirm the specific network before relying on its coverage.

How current is this list?

Every entry carries the date we last checked it against the brand's own public disclosures; the newest check on this page is September 12, 2026. Brands get acquired and switch networks, so we date each record separately and re-check them individually. If you spot something out of date, please report a correction.

No guarantee. Coverage and availability change and can differ between neighboring addresses. Results here are informational, sourced and dated where possible, and not a guarantee of service. Always verify directly with the provider before ordering. Spotted something wrong? Report a correction.
