- Go to Settings > Cellular > Cellular Data Network.
- Type "h2g2" (without quotation marks) in the APN field.
After entering the APN settings, go back to the Google Fi app and complete the setup process. Your iPhone should now connect and work on Google Fi without issue.
Understanding Google Fi
Google Fi Wireless operates as an MVNO, which means it doesn't own its own cellular network, but instead partners with established Mobile Network Operators to lease network capacity.
Google Fi primarily utilizes T-Mobile's robust 5G and 4G LTE network in the US, and on iPhones, you'll primarily be using the T-Mobile network.
This approach allows Google Fi to offer service to its customers under its own brand, without having to own and operate its own physical cell towers.

What Is Wireless?
Wireless is a way for your phone to connect to the internet and make calls without being physically connected to a physical network. This technology uses radio waves to transmit data between devices.
Unlike traditional landline phones, wireless phones can be used anywhere within range of a cellular network. Google Fi Wireless operates as an MVNO, which means it doesn't own and operate its own cellular network.
Broaden your view: Google Fi Bring Your Own Phone
Brief Overview:
Google Fi is a unique mobile service that doesn't own its own cell towers. It partners with established Mobile Network Operators (MNOs) like T-Mobile to provide service to its customers.
By leasing network capacity from T-Mobile, Google Fi can offer its customers a robust 5G and 4G LTE network in the US. This partnership allows Google Fi to provide reliable coverage to its users.
Google Fi has historically used networks like Sprint (now part of T-Mobile) and US Cellular, employing intelligent network switching on certain Android phones. This means that Google Fi can automatically switch between different networks to find the best connection for its users.
On iPhones, however, Google Fi customers primarily use the T-Mobile network.

Unlocked Device Importance
Having an unlocked iPhone is crucial for using Google Fi. An unlocked phone isn't tied to a specific carrier's network.
Phones purchased directly from Apple are typically unlocked, which is convenient. Phones bought through carrier financing plans are often locked until paid off, so be sure to pay off your device before switching carriers.
To check if your iPhone is unlocked, you'll need to go to Settings > General > About. If it says “No SIM restrictions,” your iPhone is unlocked, and you're good to go.
If your iPhone is locked, you'll need to contact your current or previous carrier to request an unlock. Ensure you meet their requirements, such as having paid off your device and being in good standing with your account.
If you prefer a physical SIM card, you can order a free SIM kit from Google Fi for older iPhones (iPhone X or earlier).

eSIM vs. Physical SIM
If your iPhone supports eSIM, the recommended and easiest method to activate Fi service is through the Google Fi app without needing a physical card. Google Fi fully supports eSIM activation on compatible iPhones, such as the XS/XR and later models.
eSIM is a digital SIM built into newer iPhones, allowing you to activate Fi service directly through the Google Fi app. This eliminates the need for a physical card, making it a convenient option.
To determine if your iPhone supports eSIM, check your model number. If it's an XS/XR or later, you're good to go.
Features and Functionality
Google Fi for iPhone offers seamless international coverage in over 200 countries, so you can stay connected no matter where your travels take you.
With Google Fi, you can easily switch between Wi-Fi and cellular networks, ensuring a smooth and uninterrupted internet experience. This means you can browse, stream, and work online without worrying about dropped connections or slow speeds.
One of the standout features of Google Fi is its transparent and affordable pricing, with no surprise fees or overage charges. You'll only pay for the data you use, with rates as low as $10 per GB.
Features: What Works and What Might Differ

Google Fi offers a range of features that work seamlessly on both Android and iPhone devices. Automatic Network Switching is one such feature that allows Fi phones to dynamically switch between T-Mobile and US Cellular for the best signal, but iPhones primarily stick to the T-Mobile network.
On the other hand, Enhanced VPN & Spam Blocking works differently on iPhone compared to Android. While Fi offers a VPN service and spam call blocking, the automatic always-on VPN connection and some advanced call screening features present on Pixel phones might not function identically or require manual activation/configuration on iOS via the Fi app.
Seamless Setup is another area where iPhone users might experience some differences. While the setup is straightforward, it does require manually downloading the app and potentially adjusting some settings (like MMS), whereas on a “Designed for Fi” phone, it’s often more deeply integrated.
To give you a better idea of what to expect, here are some key differences in Google Fi features on iPhone compared to Android:
- Automatic Network Switching: iPhone primarily sticks to the T-Mobile network, while Fi phones can dynamically switch between T-Mobile and US Cellular.
- Enhanced VPN & Spam Blocking: iPhone users may need to manually activate/configure some features via the Fi app, whereas Android users get them automatically.
- Seamless Setup: iPhone users need to manually download the app and adjust settings, while Android users get a more integrated experience.
Data Hotspot/Tethering
You can use your iPhone as a personal hotspot with Fi, and your hotspot data usage counts towards your monthly high-speed data allowance.
For instance, if you have the Flexible plan, you get up to 15GB of high-speed data for tethering before throttling kicks in.

10th Anniversary with 5G & Visual Voicemail
Google Fi is celebrating its 10th anniversary with a handful of exciting updates. The Google Fi Wireless set-up process on iPhone is getting simpler, with no need to manually enter carrier information to get service up and running.
The actual activation period is also getting faster. This is a game-changer for those who want to start using Google Fi ASAP.
Visual voicemail is being integrated into the Phone app, making it easier to check voicemails. This feature is rolling out in the coming weeks, so stay tuned.
International 5G service is now available in 92 countries for iPhone owners on the Unlimited Premium and Flexible plans. This is a huge upgrade for those who travel frequently.

Google Fi is also adding support for data-only eSIMs. This is perfect for tablets that no longer have a physical SIM card slot.
To enable 5G coverage on your iPhone, make sure you're using an iPhone 12 or newer and have iOS 16.4 or higher. Then, follow the steps in the Settings app to select 5G Auto.
Android Differences and Considerations
If you're considering switching to Google Fi on your iPhone, it's essential to understand the differences in features and functionality compared to Android phones designed for Google Fi. Some advanced features may work differently or require manual setup.
Automatic Network Switching is one feature that differs between iPhone and Android phones designed for Fi. iPhones primarily stick to the T-Mobile network, whereas Android phones can dynamically switch between T-Mobile and US Cellular for the best signal.
You'll still get the basics with Google Fi on your iPhone, including spam warnings and the option to enable the Fi VPN. However, some advanced call screening features present on Pixel phones might not function identically or require manual activation/configuration on iOS via the Fi app.
Seamless Setup is a feature that's not as seamless on iPhones as it is on Android phones designed for Fi. You'll need to manually download the app and potentially adjust some settings, like MMS.
