A new super network feature switches phones between two 5G carriers to prevent dead zones and slow data.
Google Fi Wireless launched a new super network feature today that automatically switches a user’s phone between two separate cellular carriers to maintain the best connection. The tool is rolling out first to Pixel 9 and newer Pixel phones equipped with eSIMs, aiming to eliminate dead zones and sluggish speeds without requiring manual input from the user.
According to Engadget, the system detects when a mobile connection is sluggish and shifts the device over to another provider. Google Fi isn’t publicly naming the cellular partners behind the service, though CNET reported the company confirmed it’s using “two top 5G networks.” Google Fi has traditionally run on T-Mobile’s network in the United States.
How the dual-network setup works
A source at Google told CNET that phones utilize two eSIM slots behind the scenes to manage the handoff between the two carriers, though the interface presents only a single eSIM to the customer. A fine-print disclaimer specifies that users must disable any other eSIM profiles on their device, which is relevant for anyone running multiple active mobile carriers on a single phone.
Plan availability and international roaming
The outlets reported conflicting information about which service tiers include the super network. CNET reported that the feature is free for existing customers across all Google Fi tiers: Flexible, Unlimited Essentials, Unlimited Standard, and Unlimited Premium. In contrast, Engadget reported that the tool is available at no extra cost to subscribers on the Flexible and Unlimited Premium plans.
Both publications confirmed that the carrier switching works during international travel. Engadget reported that the functionality operates in over 200 destinations around the world, while CNET noted that global switching is part of the Flexible and Unlimited Premium plans.
Expanded Wi-Fi connections and Ask Fi support
Alongside cellular switching, Google Fi introduced an expanded Wi-Fi Auto-Connect Plus feature. The system connects a phone to an encrypted Wi-Fi network when cellular reception is spotty or interfered with by buildings, provided a compatible Wi-Fi network is stronger. CNET reported the feature is active across millions of additional locations in the United States, while Engadget noted availability in malls, airports, and select locations in Europe, Asia, and Brazil.
Wi-Fi Auto-Connect Plus works on Pixel 5a and newer models, select modern Motorola handsets, and Samsung phones running One UI 9 or later. In addition, Google Fi is rolling out Ask Fi, an artificial intelligence tool inside its app to help customers troubleshoot connectivity issues and handle billing questions in real time. Engadget noted that customers who prefer not to use the automated agent can still contact human support representatives.
Device promotions and future rollout
Google Fi is running device promotions alongside the launch. New subscribers can receive a Pixel 11 Pro through a $500 instant rebate and $599 in bill credits spread over 24 months, plus a $10 monthly credit when signing up for an Unlimited Premium plan before the offer ends on 11/18/26. New subscribers who already own a Pixel phone can get 50 percent off select unlimited plans for 12 months under an offer ending 12/1/26.
Wider availability of the super network feature beyond Pixel models is scheduled to arrive in 2027.
