Google Fi Wireless will now move Pixel 9 and newer phones between two US 5G networks automatically. Google calls the setup its super network. It began rolling out gradually on November 10 and costs nothing extra on any Fi plan.
The catch is who actually gets it. Network switching needs a Pixel 9 or newer, Fi running on eSIM, and every non-Fi SIM disabled. Pixel 8 and older Pixels miss out. So do Samsung and Motorola phones on Fi.
How Google Fi network switching works
Each eligible phone gets a Primary network and a Secondary network. Google’s announcement does not name the carrier behind the Secondary one. According to 9to5Google, there is no manual switching at launch, so the phone decides when to move.
The feature leans on Android’s Multiple Enabled Profiles (MEP) support. MEP lets a single eSIM chip run two carrier profiles at the same time. Mauria Finley, Google’s VP for Google Store and Google Fi, described the goal in the announcement:
If your primary connection drops, Google Fi moves you to a secondary data connection so you can stay on a strong, reliable signal—hitting fewer dead zones on the highway, down country roads, and wherever else your day takes you.
Google also claims that, unlike other major carriers, only Fi switches you between networks in real time. Its footnote defines a major carrier as an operator or MVNO with more than 1 million US customers as of March 2025. Google adds that both networks rank among America’s fastest, citing Ookla and RootMetrics data for the first half of 2026.
9to5Google reports that the Fi app gains a Your super network card showing the Primary and Secondary networks. A See activity view lists past switches. The site also says Primary network data is never deprioritized and the Secondary gets the highest QCI priority. That is 9to5Google’s summary of Google’s briefing, so don’t read it as a guarantee for every plan.
The SIM rule is the real tradeoff here. If you keep a work line or a travel SIM active next to Fi, you have to switch it off to get network switching. Pixel 8 owners on Fi get none of the headline feature, however long they’ve been customers.
Wi-Fi Auto Connect+ reaches Samsung and Motorola
Samsung, Motorola and older Pixel owners do get one upgrade: Wi-Fi Auto Connect+, or W+. It is no longer limited to Pixels. Google lists these phones as supported:
- Pixel: Pixel 5a or newer, running Android 14 or higher
- Samsung: phones running One UI 9 or higher
- Motorola: select modern Motorola phones
According to the Fi Help Center, data used over W+ doesn’t count against your monthly data limit. Google says these Wi-Fi connections are encrypted through the Fi Virtual Carrier Network. So Samsung and Motorola owners get W+, but not the switching between cellular networks.
Using it abroad, and the new Ask Fi assistant
Network switching and W+ also work outside the US on the Unlimited Premium and Flexible plans. Google caps international high-speed data at up to 50 GB per person on Unlimited Premium and 15 GB on Flexible. After that, speeds drop to 256 kbps. The Fi app also adds Ask Fi, an AI support agent for account help and troubleshooting.
Google Fi offers: Pixel 11 Pro deal and 50% off unlimited
New subscribers who buy a Pixel 11 Pro from fi.google.com get $500 off instantly. They also get $599 back as 24 monthly credits, plus a $10 monthly service credit for two years on Unlimited Premium. That works out to $34.96 in credits each month ($24.96 plus $10). The offer ends November 18.
The terms matter here. You must activate on a new Unlimited Premium plan within 30 days. The line has to stay active for 120 consecutive days to keep the $500 discount. Cancel before 24 months and you lose the remaining credits. Change plans early and the $10 monthly credit stops.
In practice, the full value only lands if you stay on Unlimited Premium for two years. If you’d rather avoid that commitment, the unlocked Google Pixel 11 Pro is sold on Amazon. The Fi credits apply only to phones bought from fi.google.com, though.
Pixel owners who aren’t on Fi can get 50% off Unlimited Standard or Unlimited Essentials for 12 months. It applies through monthly bill credits. You qualify only if you haven’t had Fi service in the last 180 days. Google’s promo terms say it runs until 9:59 AM PST on December 1. The banner on Google’s Fi site says November 30, so treat the end of November as the safe deadline.
