Google Fi is a cell service by Google offering flexible plans and international coverage, while Xfinity Mobile is a wireless service by Comcast focusing on bundling with internet and cable services.

Key Differences

Google Fi, a telecommunications service by Google, is known for its flexible plans that cater to varying data needs and its emphasis on easy international travel usage. Xfinity Mobile, operated by Comcast, is often recognized for its wireless service that integrates well with Comcast's internet and cable services, offering benefits for bundling.
Google Fi operates on a unique system where it switches between multiple networks and Wi-Fi for optimal signal, aiming to provide consistent service quality. Xfinity Mobile primarily uses Verizon's network and leverages millions of Xfinity Wi-Fi hotspots nationwide to provide coverage.
In terms of international usage, Google Fi stands out with its straightforward international rates in over 200 countries, making it a preferred choice for frequent travelers. Xfinity Mobile, while offering international options, is more focused on domestic use within the United States.
Google Fi's pricing model is based on pay-for-what-you-use data, which can be beneficial for low data users or those with fluctuating data needs. Xfinity Mobile offers competitive plans but is particularly advantageous for existing Xfinity customers due to the bundling discounts.
Both services provide access to 5G networks, but Google Fi is known for its compatibility with a wide range of phones, whereas Xfinity Mobile has some restrictions on device compatibility, favoring Comcast's own network and services.
