Google Fi’s Super Network, rolled out starting November 10, 2026, automatically switches eligible Pixel phones between two 5G networks for stronger coverage and fewer dead zones. Configuration is mostly about meeting the device and SIM requirements so the automatic switching can activate. Once set up correctly, the phone handles the rest in the background with no manual toggles.
This guide walks beginners and professionals through the exact steps to enable and verify the second 5G network on Google Fi. The process takes about 10–20 minutes if your phone already qualifies.
What You Need
- AGoogle Pixel 9, Pixel 10, or Pixel 11 seriesphone (older models receive support in 2027)
- An active Google Fi plan (available on all plans, including Flexible, Unlimited Essentials, Unlimited Standard, and Unlimited Premium)
- Google Fi installed as aneSIM(embedded SIM—a digital SIM stored on the phone rather than a physical card)
- The latest Google Fi app and Android system updates
- A stable Wi-Fi connection for app and system updates
- Any other SIMs or eSIMs disabled (required for Super Network switching)
Important:Network switching uses Multiple Enabled Profiles (MEP) eSIM technology. MEP lets one eSIM chip run two carrier profiles at the same time so the phone can maintain live connections to both networks and switch instantly when signal quality drops.
Step-by-Step Guide
Step 1: Confirm your phone model and software version
Open the Settings app and go to About phone. Check the model name. Only Pixel 9 and newer devices support domestic Super Network switching at launch.
While there, tap System updates (or Software update) and install any available Android updates. Many users see the Super Network features appear after the latest system update or QPR (Quarterly Platform Release).
Step 2: Update the Google Fi app
Open the Google Play Store, search for Google Fi, and tap Update if available. The updated app adds the “Your super network” card and switching activity view.
Restart your phone after updating to ensure the new components load properly.
Step 3: Convert Google Fi to eSIM (if currently on a physical SIM)
If your Fi service is already on eSIM, skip to Step 4. Physical SIMs cannot use the dual-profile switching.
Open the Google Fi app → Account or Settings → look for the option to transfer or activate eSIM. Follow the on-screen prompts. You may need to scan a QR code or confirm via the app. After activation, remove the physical SIM if present.
Typical path: Google Fi app → Settings → Transfer to eSIM
or
Settings → Network & internet → SIMs → Google Fi → Convert to eSIMKeep Wi-Fi connected during the transfer so you do not lose service.
Step 4: Disable every non-Fi SIM
This is the most common requirement that blocks the feature. Super Network switching only works when Google Fi is the sole active SIM.
Go to Settings → Network & internet → SIMs. For every profile that is not Google Fi, tap it and turn the toggle off. Do the same for any physical SIM tray slots.
Warning:Disabling other SIMs means you cannot use a work line or travel eSIM at the same time as Super Network switching. Re-enable them later if needed, but switching will stop until they are turned off again.
Step 5: Verify the Super Network card appears
Open the Google Fi app and check the Home tab. Look for a new card labeled “Your super network.” It should show whether you are currently on the Primary or Secondary network.
Tap “See activity” (or similar) to view recent switching history, timestamps, and connection quality notes. If the card is missing, wait 15–30 minutes, restart the phone, and confirm Steps 3 and 4 again. The feature rolls out gradually.
Step 6: Understand how automatic switching works
There is no manual network selection toggle at launch. The phone continuously evaluates signal strength, data speeds, latency, and battery level. It stays on the primary network when that connection is healthy and moves to the secondary network only when the primary becomes weak or unavailable and the alternate offers a meaningfully better connection.
Primary network data receives top priority and is never deprioritized. The secondary network receives the highest QCI (QoS Class Identifier) priority, meaning you are among the last users slowed during congestion. Ultra Wideband is supported on both where available.
Step 7: Enable related Super Network features (optional but recommended)
Wi-Fi Auto Connect+ is part of the Super Network experience. It automatically joins vetted public Wi-Fi networks (airports, malls, etc.) with encryption through Google Fi’s Virtual Carrier Network. No manual login is required.
In the Google Fi app or phone Settings → Network & internet → Internet, confirm automatic Wi-Fi connection options are enabled. The feature works on Pixel devices and is expanding to select Samsung and Motorola phones.
Step 8: Test the connection in real conditions
Move to an area where your previous signal was weak. Watch the status bar and the Fi app’s Super Network card. You may briefly see a network change notification or indicator. Data sessions, calls (routed over data), and messaging should continue without interruption.
Check the activity log later to confirm a switch occurred. Battery impact is minimal because the phone uses conservative switching when Battery Saver is on or the battery is low.
Common Mistakes
- Leaving a second SIM or eSIM active—switching will not start until every non-Fi profile is disabled
- Using a physical SIM instead of eSIM—MEP dual-profile support requires the eSIM
- Running an outdated Google Fi app or Android version—the Super Network card and logic arrive via updates
- Expecting manual control—there is no dialer code or settings toggle to force the secondary network at launch
- Checking too soon after setup—gradual rollout means some devices need a few hours or a reboot before the card appears
- Assuming every location is covered—network switching is not available in all areas; results vary by signal and local partner coverage
Troubleshooting
If the Super Network card never appears after following the steps above:
- Force-stop the Google Fi app (Settings → Apps → Google Fi → Force stop), clear cache, then reopen
- Restart the phone twice—once after app update, once after SIM changes
- Confirm the phone is on the latest Android build via Settings → System → System update
- Check that you are signed into the same Google account that owns the Fi plan
- Contact Google Fi support through the app’s Ask Fi AI assistant (new with the Super Network update) or human chat for account-side activation issues
For persistent signal problems, note the location and time, then review the activity log. International switching on Unlimited Premium and Flexible plans follows the same eSIM rules and works in 200+ destinations.
Final Check
After setup you should see:
- Only the Google Fi eSIM active in Settings → Network & internet → SIMs
- The “Your super network” card on the Fi app Home tab
- Recent activity showing Primary or Secondary network status
- Continued service with no drop when moving between areas of differing coverage
Run a quick speed test on cellular data in a known weak spot and compare against previous results. The secondary network should improve reliability where the primary alone previously failed.
Summary
Configuring Google Fi for the second 5G network centers on three practical requirements: a Pixel 9 or newer phone, Google Fi running on eSIM, and every other SIM disabled. Once those are met and the app and system are updated, Super Network switching activates automatically using MEP technology. You can monitor it in the Fi app’s activity view, and related features such as Wi-Fi Auto Connect+ further reduce dead zones indoors.
Next steps: Test in your usual routes for a day or two and review the activity log. If you travel internationally, confirm your plan tier supports the global version.

Enjoy more consistent connectivity without any ongoing manual work.
