# Mobile virtual network operator (MVNO)

> An MVNO is a mobile operator that sells service under its own brand on another operator's radio network. Why carrier lookups name MVNOs, and what it means for SMS and fraud checks.

*Carrier lookup returns the line type (mobile, landline or VoIP) and the network behind the number.*


A mobile virtual network operator (MVNO) is a mobile service provider that sells SIM cards, plans and numbers under its own brand but doesn't own the radio network its customers use. It buys access wholesale from a host mobile network operator (MNO) and resells it. Budget brands, prepaid brands, retailers' and cable companies' mobile offers are often MVNOs.

## How does an MVNO work?

The host operator carries the radio traffic. How much else the MVNO runs varies:

- **Light (branded) MVNOs** handle marketing, sales and customer service. The host runs almost everything else, including SIMs, numbering and the subscriber database.
- **Full MVNOs** run their own core-network elements, such as the subscriber database (HLR/HSS), billing and SIM platform, and may have their own mobile network code.

A full MVNO can hold its own mobile network code, assigned nationally under the ITU's identification plan ([ITU-T E.212](https://www.itu.int/rec/T-REC-E.212/en)). In that case a network query can return an [MCC/MNC](/glossary/mcc-mnc) that belongs to the MVNO rather than the host. A light MVNO usually appears under the host's code.

## Why do carrier lookups name MVNOs inconsistently?

A [carrier lookup](/services/carrier-lookup) returns the network that data sources associate with a number. For MVNO customers that can be:

| What the lookup returns | Why |
|---|---|
| The host network | Light MVNO, or data keyed by the host's network code |
| The MVNO brand | Full MVNO with its own code, or a porting record that names it |
| An old brand | The MVNO was renamed, merged or sold |
| The original range holder | The number was [ported](/glossary/mobile-number-portability) and the lookup used the prefix, not current data |

So a carrier name that doesn't match the customer's bill isn't an error in itself. See [why carrier lookups go wrong](/blog/mobile-number-portability-why-carrier-lookups-can-be-wrong).

## Why does it matter for deliverability and fraud?

- **Routing and pricing.** Some SMS routes and wholesale rates differ per destination network. Knowing the real serving network, not the brand, helps route correctly.
- **Line type.** Most MVNO numbers are ordinary mobile numbers and receive SMS. Some app-based providers use [VoIP numbers](/glossary/voip-number) instead, which a [line type](/glossary/line-type) check shows.
- **Fraud signals.** Prepaid and low-cost virtual providers are popular with honest, price-conscious users and with people creating throwaway accounts alike. Treat an MVNO as context, never as a verdict, and combine it with line type, messaging-app presence and your own history.

## How does MobileValidate report MVNOs?

Our [carrier lookup](/services/carrier-lookup) returns the current `carrier` and `line_type`, plus `original_carrier` when the number was ported. Carrier names are returned as we hold them, so an MVNO may appear under its own brand or under its host network. The [US and Canada carrier lookup](/services/us-carrier-lookup) covers North American numbers in bulk. When we hold no data, the answer is `unknown` and free.

## Frequently asked questions

### Why does a carrier lookup show a different carrier than my phone bill?

Your provider may be an MVNO that runs on another operator's network. Depending on how the MVNO is set up and what the data source holds, a lookup may return the host network, the MVNO, or an older brand name.

### Is an MVNO number a fraud risk?

No, not in itself. Millions of people use MVNOs, often prepaid, for price reasons. Some app-based and low-cost virtual providers are popular for throwaway accounts, so an MVNO name is at most one signal among several.

### Does an MVNO number count as mobile?

Usually yes. MVNO numbers are ordinary mobile numbers on a mobile network and can receive SMS. Some app-based providers use VoIP numbers instead, which a line-type check reports as voip.
