A carrier or operator is a company that provides mobile network services to customers. These services can include voice, data, and messaging capabilities, as well as access to the internet. Automated mobile connections are made possible by carriers or operators, allowing users to access applications, websites, and other services with their mobile devices.

When it comes to mobile affiliate marketing, some offers may only convert on one carrier or operator. This means that the offer is only available to customers of that specific carrier or operator. For example, an offer for a mobile app subscription may only be available to customers of a particular mobile network provider.

The reason for restricting offers to a single carrier or operator is usually due to the offer being tailored to the specific audience of that carrier. For example, an app subscription offer may be designed to appeal to the users of a specific carrier or operator. There may also be technical limitations that prevent the offer from being available on other carriers.

Many offers are available on multiple carriers or operators, allowing affiliates to target a broader audience and increase their potential conversions.

It's important to check the offer details and restrictions before promoting an offer to ensure that you are targeting the right audience and complying with any restrictions or guidelines set by the advertiser. Additionally, it's important to test different offers and carriers to determine which ones are the most profitable for your particular audience and traffic sources.
