US Wireless Carriers and MVNOs: Reference List
The United States has three facilities-based national wireless carriers that own and operate wireless network infrastructure: AT&T, T-Mobile, and Verizon. Every other US wireless brand, generally called a mobile virtual network operator or MVNO, leases network capacity from one or more of those three rather than building its own towers and spectrum. Understanding which host network an MVNO runs on matters for coverage planning, for troubleshooting delivery issues, and for anyone documenting how application-to-person (A2P) text messages travel from a sending platform to a handset.
This page is a maintained reference, not a one-time snapshot. MVNO ownership and host-network agreements change: brands get acquired, contracts get renegotiated, and a carrier that hosted an MVNO on one network can shift it to another. Treat the relationships below as current as of the most recent update and confirm directly with the carrier or MVNO for anything decision-critical.
The Three Facilities-Based National Networks
Nearly every wireless plan sold in the United States ultimately rides on one of three physical networks. These three carriers, sometimes called "the Big Three," build and maintain the cell towers, spectrum licenses, and core network infrastructure that both their own retail brands and third-party MVNOs depend on.
- AT&T, which also operates the Cricket Wireless prepaid brand directly
- T-Mobile, which also operates Metro by T-Mobile directly and owns Mint Mobile
- Verizon, which also operates Visible directly
Every carrier and MVNO listed below ultimately connects to one or more of these three networks for radio access, even when the retail brand, billing relationship, and customer support are entirely separate from the host carrier.
MVNO to Host Network Reference Table
The table below lists well-known MVNOs alongside the host network they operate on. Some MVNOs offer plans on more than one host network and let the customer or an automated system choose; those are marked as multi-network.
| Brand | Type | Host Network | Ownership Note |
|---|---|---|---|
| AT&T | Facilities-based carrier | AT&T (own network) | National carrier |
| T-Mobile | Facilities-based carrier | T-Mobile (own network) | National carrier |
| Verizon | Facilities-based carrier | Verizon (own network) | National carrier |
| Cricket Wireless | MVNO / retail brand | AT&T | Owned by AT&T |
| Consumer Cellular | MVNO | AT&T (T-Mobile on some lines) | Independent; confirm per line, since Consumer Cellular has used both networks |
| Metro by T-Mobile | MVNO / retail brand | T-Mobile | Owned by T-Mobile |
| Mint Mobile | MVNO | T-Mobile | Owned by T-Mobile |
| Google Fi | MVNO | T-Mobile | Owned by Google; primary radio access via T-Mobile |
| Tello | MVNO | T-Mobile | Independent |
| Visible | MVNO | Verizon | Owned by Verizon |
| Xfinity Mobile | MVNO | Verizon | Owned by Comcast; leases Verizon network |
| Spectrum Mobile | MVNO | Verizon | Owned by Charter; leases Verizon network |
| Straight Talk | MVNO | Verizon | Owned by TracFone Wireless (Verizon) |
| US Mobile | MVNO | Multi-network (Verizon, T-Mobile, and AT&T options) | Independent; customer selects network at signup |
| Boost Mobile | MVNO | AT&T | Owned by EchoStar; shut down its own network in November 2025 and now runs as a hybrid MVNO on AT&T |
This is a representative sample of well-established brands, not an exhaustive list of every MVNO operating in the US. New MVNOs launch and existing ones change hosts on an ongoing basis, particularly smaller regional and affinity-brand MVNOs that resell capacity through intermediate wholesale aggregators rather than contracting with a host network directly.
Why the Host Network Matters for A2P Texting
For anyone sending application-to-person text messages, whether appointment reminders, marketing messages, or two-way conversational SMS, the host network is what actually performs delivery to the handset once a message leaves the messaging platform and passes through the carrier ecosystem. A message addressed to a Mint Mobile subscriber is, from a network perspective, being delivered over T-Mobile's infrastructure, even though the sending platform's records show the number as belonging to Mint Mobile.
This distinction shows up in a few practical ways:
- Carrier filtering decisions are generally made at the host network level, so understanding what host network a number sits on helps explain why a message might be filtered differently than expected. Our guide to what carrier filtering is covers how that filtering process works.
- A2P 10DLC registration routes traffic through the host networks' shared infrastructure for standard long code messaging, so registration and throughput limits are tied to the underlying network relationships rather than the retail brand name. See our explanation of A2P 10DLC for how that registration process works.
- Carrier fees charged on A2P messages are typically set and collected by the host network, meaning messages to an MVNO subscriber are usually billed according to the host carrier's fee schedule rather than a separate MVNO-specific rate. Our breakdown of how SMS carrier fees work explains where those charges come from.
How MVNOs Differ From Their Host Networks
An MVNO does not own spectrum or towers. Instead, it signs a wholesale agreement with a host network to purchase network access, then resells that access under its own brand, pricing, and customer service organization. Some MVNOs, sometimes called "MVNO lite" or full MVNOs depending on how much of the network stack they control themselves, manage their own billing systems, SIM provisioning, and customer support while still depending entirely on the host for radio access and core routing.
Because the underlying radio access is the host network's, coverage maps for an MVNO generally mirror the host network's coverage, though some MVNOs negotiate deprioritization terms that affect data speeds during network congestion relative to the host's own retail customers. That deprioritization is generally described as affecting data speeds rather than SMS or MMS delivery, though terms vary by agreement, so confirm per vendor. It is a distinction worth knowing when troubleshooting a mixed complaint about "texts arriving late but calls sound fine" or similar reports.
Multi-Network and Network-Agnostic MVNOs
A smaller category of MVNO does not commit to a single host network. Instead, these providers maintain wholesale agreements with more than one of the three national networks and assign subscribers, or even individual SIMs, to whichever network performs best at a given location, or let the subscriber choose at signup. US Mobile is a well-known example of this model, offering separate plan tiers tied to different host networks under one brand.
For anyone mapping delivery paths for text messaging at scale, multi-network MVNOs are worth flagging separately from single-host MVNOs, since a phone number on one of these carriers cannot be assumed to sit on a single fixed host network without checking the specific account.
How to Verify a Number's Host Network Yourself
Because host-network relationships shift over time, relying on a static list alone is not a reliable long-term strategy for anything decision-critical, such as diagnosing a delivery problem or documenting a compliance workflow. A few practical ways to confirm the current host network for a specific number or brand include:
- Checking the MVNO's own support pages or terms of service, which frequently disclose the underlying network relationship directly, particularly for SIM compatibility and coverage map purposes
- Using a carrier lookup service that identifies the current network operator associated with a specific phone number, which many messaging platforms and telecom data providers offer as a standard tool
- Reviewing recent, dated coverage or plan comparison articles rather than older ones, since MVNO-to-host relationships have changed more than once for several well-known brands over the years
- Contacting the MVNO directly if the answer needs to be authoritative for a specific business decision, since public documentation can lag behind a recent contract change
Keeping This Reference Current
Wholesale carrier agreements are commercial contracts, and like any contract, they get renegotiated, expire, or change hands when a parent company is acquired. A brand that hosted its service on one network for years can move to a different network with little public notice beyond a coverage map update, and some brands blend networks gradually during a transition period rather than switching all at once. Anyone using this table for an important operational decision, such as troubleshooting a specific delivery issue or documenting a carrier relationship for a compliance record, should treat it as a helpful starting point rather than a final answer, and should verify the specific relationship in question through the methods above when precision matters.
Frequently Asked Questions
What does MVNO stand for?
MVNO stands for mobile virtual network operator. It refers to a wireless carrier brand that sells service to consumers without owning the underlying network infrastructure, instead purchasing wholesale network access from one of the facilities-based national carriers, primarily AT&T, T-Mobile, or Verizon.
What network does Mint Mobile use?
Mint Mobile operates on T-Mobile's network. Mint Mobile is owned by T-Mobile, which acquired the brand outright, so its subscribers connect through T-Mobile's radio access network and core infrastructure.
What network does Visible use?
Visible operates on Verizon's network. Visible is owned directly by Verizon and was launched by Verizon as a digital-first, lower-cost retail brand running on Verizon's own infrastructure.
What network does Cricket Wireless use?
Cricket Wireless operates on AT&T's network. Cricket is a prepaid brand owned and operated directly by AT&T, so it runs on the same underlying infrastructure as AT&T's postpaid service.
Are there only three wireless networks in the United States?
There are three major facilities-based national wireless networks in the United States: AT&T, T-Mobile, and Verizon. Nearly every other wireless brand, including dozens of MVNOs, purchases wholesale access to one or more of these three networks rather than operating independent nationwide infrastructure.
Can an MVNO change which network it uses?
Yes. An MVNO's host network is set by a commercial wholesale agreement, and that agreement can change when it expires, is renegotiated, or when the MVNO is acquired by a different owner. Because these relationships can shift, any list of MVNO-to-host mappings should be treated as needing periodic verification rather than permanent.
Why does the host network matter for text message delivery?
The host network is the infrastructure that actually delivers a text message to a handset, handles A2P 10DLC registration and throughput, and applies carrier-level message filtering, regardless of the retail brand name on the subscriber's bill. Understanding the host network helps explain delivery behavior, filtering decisions, and fee structures for messages sent to MVNO subscribers.
Do MVNO subscribers pay different carrier fees for text messages?
Carrier fees for A2P text messages are generally set by the host network rather than the MVNO brand, so messages sent to an MVNO subscriber are typically billed to the sending platform according to the host carrier's fee schedule rather than a separate rate specific to the MVNO.
