Google Fi APN Settings for Android and iPhone

Google Fi runs on T-Mobile's network, and phones designed for Fi can also switch between multiple major 4G LTE networks and Wi-Fi. For most people on Pixel phones or other designed-for-Fi devices, APN settings fill in automatically and the network just works.

On other phones, including older iPhones and some Android devices, you sometimes need to enter APN values by hand. Here is the configuration Google Fi lists in its own help pages.

What Makes Google Fi Different

• Google Fi is multi-network on designed-for-Fi phones, which can use multiple major 4G LTE networks or 5G on T-Mobile's network. Fi-compatible phones stay on T-Mobile, with no intelligent network switching.
• On iPhone, the APN is h2g2 for cellular data, LTE setup and MMS, and h2g2-t for Personal Hotspot. For Android data or SMS problems, Google Fi lists h2g2-t as the APN.
• Designed-for-Fi phones (Pixel 2 and later, plus select Motorola and Samsung Galaxy models) get their settings automatically. You do not need to enter an APN on these phones.
• Google Fi says you no longer have to enter APN and MMS settings by hand during activation. Manual entry is mainly for iPhones on iOS 16.3 or earlier and for Android phones with data or SMS problems.

Opening the APN Screen

Before you enter values by hand, check whether your phone shows Google Fi or Fi Network as the carrier name. If it does, the carrier profile is loaded. Test data and MMS first, and only enter values if one of them is failing.

Android

1. 1.Open Settings
2. 2.Tap Network & internet or Connections
3. 3.Tap SIMs (or Mobile network on some phones), then your Google Fi SIM

8. 8.Restart the phone

iPhone and iPad

1. 1.Open Settings
2. 2.Tap Cellular or Mobile Data
3. 3.Tap Cellular Data Network
4. 4.Enter the iPhone values from the list below, then restart your iPhone

Google Fi Android APN Values

For Android phones with data or SMS problems, use these values:

• Name: Google Fi
• APN: h2g2-t
• Proxy: <Not set>
• Port: <Not set>
• Username: <Not set>
• Password: <Not set>
• Server: <Not set>
• MMSC: https://m.google.com/mms/wapenc
• MMS proxy: <Not set>
• MMS port: <Not set>
• MCC: 310
• MNC: 260
• Authentication Type: None
• APN Type: default,supl,mms,ia
• APN Protocol: IPv4/IPv6
• APN Roaming Protocol: IPv4/IPv6
• Bearer: Unspecified

The APN and MMSC are the values Google Fi specifies. If your phone already fills in the other fields, leave them as they are.

Google Fi iPhone APN Values

Google Fi only asks you to enter these by hand if your iPhone runs iOS 16.3 or earlier. On newer iOS versions, try them only if MMS or hotspot is still failing:

• Cellular Data / Mobile Data (APN): h2g2
• Username: <Not set>
• Password: <Not set>
• LTE Setup (APN): h2g2
• MMS:
  • APN: h2g2
  • MMSC: http://m.fi.goog/mms/wapenc
  • MMS Proxy: <Not set>
  • MMS Max Message Size: 23456789
  • MMS UA Prof URL: <Not set>
• Personal Hotspot:
  • APN: h2g2-t
  • Username: <Not set>
  • Password: <Not set>

Enter 23456789 in the MMS Max Message Size field exactly as shown. The actual limit for Fi picture and video messages is 8 MB, or 1 MB for international messages.

Designed-for-Fi Phones and Compatibility

Google Fi has two compatibility tiers. Designed-for-Fi phones get full Fi functionality, including calls, texts and data on multiple major 4G LTE networks or 5G on T-Mobile's network, with intelligent network switching. Fi-compatible phones work on T-Mobile's network only, with no intelligent network switching.

Designed-for-Fi phones include Pixel 2 and later, select Motorola models such as the North American Moto G series, and select Samsung Galaxy A, S and Z series phones. iPhones are Fi-compatible, not designed for Fi, but they still support Wi-Fi calling, which you turn on in the Google Fi app under Home, then Network tips.

To work on Fi, an Android phone needs Android 7.0 or later, LTE bands 2 and 4 and VoLTE support, and an iPhone needs iOS 13 or later. Activating new service or an eSIM on Android needs Android 11 or later, and Android 11 and later are fully supported. Manual APN entry is more often needed on phones that are not designed for Fi.

Common Google Fi APN Issues

After saving an Android APN, restart the phone. The new entry sometimes does not become active until the phone reconnects to the network.

On iPhone, the most common MMS problem is a wrong MMSC value. Use http://m.fi.goog/mms/wapenc and restart after saving.

For Personal Hotspot on iPhone, the APN field must be h2g2-t, with the dash and the t.

If data still does not work on Android, check that Mobile data is on and Airplane mode is off, update the Google Fi app from the Play Store, and set the preferred network type to 5G (recommended). As a last resort, go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. This also removes the SIM data, so open the Google Fi app afterward to reactivate your service.

If MMS fails on iPhone and the MMSC and MMS Max Message Size both look correct, confirm that MMS Messaging is on at Settings > Messages. If you are roaming, also turn on Data Roaming under Settings > Cellular > Cellular Data Options.

If your phone shows No Service after moving to Google Fi, install any pending iOS or Android update and run Reset Network Settings. Also make sure the phone is unlocked from your previous carrier, because a locked phone can cause activation errors.

If you moved your Fi service to a different phone and service is degraded, open the Google Fi app on the new phone and finish the activation steps. Contact Fi support if the problem continues.

Frequently Asked Questions

What does h2g2 stand for?

It is a common nod to The Hitchhiker's Guide to the Galaxy, the Douglas Adams novel that fans abbreviate as H2G2. The name has no technical meaning. It is simply the APN value the network expects, typed in lowercase.

Why does iPhone use h2g2-t for Personal Hotspot?

Google Fi lists h2g2-t as the Personal Hotspot APN on iPhone, separate from the h2g2 value used for cellular data and MMS. Enter it exactly as shown, or hotspot may not work.

Why is the MMS Max Message Size 23456789 instead of 1048576?

23456789 is the value Google Fi tells iPhone users to enter. It is a field setting, not your real limit. Fi caps MMS files at 8 MB, and international messages at 1 MB.

I have a Pixel. Do I need to enter any APN values?

No. Pixel 2 and later are designed for Fi and receive the carrier settings automatically. If something is not working on a Pixel, the problem is unlikely to be the APN, so start with the data troubleshooting steps above.

Can I use Google Fi on an unlocked iPhone?

Yes, as long as it runs iOS 13 or later. iPhones stay on T-Mobile's network without Fi's network switching, but they do support Wi-Fi calling through the Google Fi app. On iOS 16.4 and later, you usually do not need to enter APN settings.

Does Google Fi work the same in 5G areas?

Yes. Google Fi's 5G runs on T-Mobile's nationwide 5G network, and the same APN covers LTE and 5G. On iPhone, 5G needs an iPhone 12 or later on iOS 16.4 or later. On Android, 5G needs Android 13 or later, and you set the preferred network type to 5G (recommended).

My Google Fi data slows down a lot at certain times. Is the APN the cause?

Probably not. Once you use your plan's fast data, Fi slows your speed to 256 kbps until the next month starts. The limits are 15 GB on Flexible, 30 GB on Unlimited Essentials, 50 GB on Unlimited Standard and 100 GB on Unlimited Premium. You can check usage under Account in the Google Fi app, and buy more fast data with Get full speed.
