What is Google Fi?
Google Fi is a carrier service that provides users with calls, messaging, Wi-Fi, cellular networks, and mobile broadband. The American- based service is owned by Google, and since it is a mobile virtual network operator, it uses T-Mobile and US Cellular as its network operators.
To ensure fast connections, Google Fi chooses between the available networks automatically, selecting the strongest option in each case. The service also uses a VPN, which encrypts the user’s data as they automatically connect to Wi-Fi hotspots and other available networks. This Virtual Private Network ensures that Google Fi users are always safe.
Google Fi exclusively works in the United States, with countries neighboring the US having some access at slightly lower signals. However, the roaming feature allows the service to work in over two hundred countries worldwide. Finally, Google Fi has both unlimited and pay-as-you-go plans. Its device compatibility is superb since it can accommodate most Android phones. There’s also a group plan that charges per user.
What is AT&T?
AT&T is an internet service founded in 2006 and is amongst the largest cable companies worldwide. AT&T offers internet, TV, and call services. Its internet service uses both fiber and Digital Subscriber Lines (DSL). The DSL uses a fiber-to-the-node application that involves fiber optic cables transmitting internet, voice-over-IP, and IPTV from the AT&T headquarters to distribution nodes strategically placed in neighborhoods. Copper wires are then used to transmit the service from these distribution nodes to the user’s home.
AT&T’s fiber service uses a fiber-to-the-premises network (FTTP). FTTP uses fiber cables similar to those in DSL, but does not involve any distribution nodes. Instead, the fiber cables go directly from AT&T’s headquarters to the user’s home. FTTP networks are faster and more efficient compared to DSL. In addition, DSL is outdated and puts the carrier at a disadvantage. Finally, AT&T only works in the US, and the service includes both pay-as-you-go and unlimited plans.
Google Fi vs. AT&T: What’s The Difference?
Google Fi and AT&T are amongst the major wireless carriers in the US. How do these internet service providers differ? Let us examine their distinguishing factors.
Services Provided
Google Fi and AT&T provide different services to their users. With Google Fi, you can access several services, from messaging, telephone calls, cellular networks, Wi-Fi, and broadband. AT&T also offers wireless networks, internet, and calls. However, the service differs from Google Fi by offering landline communication, fiber internet, and digital television. AT&T ultimately has more to offer than Google Fi, thus winning this round.
Internet type
One of the major differences between Google Fi and AT&T is the type of internet they offer to their users. Google Fi is a mobile virtual network operator. Being an MVNO, the carrier offers wireless internet from two different operators, T Mobile, and US Cellular. Google Fi does not own the two operators, and they only help provide internet service. As a result, as you use Google Fi, you automatically toggle between the two operators depending on which has the fastest speeds.
Contrastingly, AT&T offers wired and wireless internet. The wireless internet is in the form of Wi-Fi, whereas the wired internet is delivered using fiber and Digital Subscriber Line (DSL). DSL is slower since it uses fiber-to-the-node applications where fiber cables transmit the services from headquarters to a distribution node. From these nodes, copper wires then transmit the service to the users. However, AT&T’s fiber internet is fast since it uses a fiber-to-the-premises network (FTTP). In this network, fiber cables similar to those in DSL go directly from AT&T headquarters to the user’s home.
Plans and Pricing
Regarding plans and pricing, Google Fi is cheaper overall. However, AT&T still offers top-notch service even if its subscriptions are more expensive. Google Fi comes with two unlimited plans and a pay-as-you-go plan. The two unlimited plans include the Simply Unlimited ($50/month) and the Unlimited Plus ($65/month). The pay-as-you-go option, Flexible, costs $20/month, with every GB going for $10.
AT&T has three different unlimited plans. The plans differ in price depending on the number of lines you need. We will be mentioning the plan prices for one line. The Unlimited Starter costs $35/month, whereas the Unlimited Extra goes for $40/month. Finally, the Unlimited Premium will cost $50/month. AT&T also has a pay-as-you-go option where users can choose their plans on AT&T’s official website.
Google Fi surely wins this round since its plans are well-priced. Additionally, the pay-as-you-go option is cheap and offers a lot of flexibility to its users.
Founders and Launch date
Google Fi and AT&T have different founders and launch dates. We will still compare the two carriers regarding founders and launch dates, even if this comparison will not have a winner. Google is the founder of Google Fi, and they officially launched the service on April 22nd, 2015. AT&T was founded on June 26th, 2006. The service originally went by U-verse Internet before later rebranding to AT&T.
Device Compatibility
AT&T wins in device compatibility by a small margin. The service works on almost all mainstream devices, from Android to Apple. You will need to get set up for the carrier’s GSM format, and you can enjoy using AT&T on any phone.
Google Fi also works on most Android devices. You can use the service on several phones, including Samsung, Pixel, and Motorola. However, Google Fi is only compatible with iPhone models running iOS 11 or later, which serves as Google Fi’s major disadvantage regarding compatibility. Additionally, you might have to check if your Android phone is compatible with Google Fi before considering the service since some phones will not work.
4G and 5G Mobile Coverage
AT&T has extensive mobile coverage, supporting both 4G and 5G connections. The service covers almost every part of all states in the US. Although most of this coverage is in 4G, it is still worth a mention. While the 5G Plus network is only available in several cities, the 5G network still reaches a lot of areas, showing how excellent AT&T’s mobile coverage is.
On the other hand, Google Fi also offers superb 4G and 5G mobile coverage. Google Fi uses T-Mobile and US Cellular to boost its range instead of using a single carrier. The service also uses Sprint for CDMA coverage in some locations. Using different operators is advantageous since Google Fi can automatically pick the strongest of the three to deliver high speeds. Google Fi enjoys top-end 5G network speeds in most locations thanks to T-Mobile.
While both carriers have great 4G and 5G coverage, AT&T has extensive mobile coverage throughout the country, narrowly beating Google Fi. However, Google Fi’s inclusion of different operators serves it well, enabling the service to follow AT&T in coverage closely.
Group plans
Group plans are a good way of saving when using carrier services. Both Google Fi and AT&T have group plans that allow users to add several lines to their accounts. If you are to subscribe to four-line group plans on the two services, Google Fi offers better deals.
The Simply Unlimited plan would cost $80/month, the Unlimited Plus plan $160/month, and the Flexible would cost $65/month and $10/GB for each user. The AT&T plans will cost $140/month for the Unlimited Starter, $160/month for the Unlimited Extra, and $200/month for the Unlimited Premium. Google Fi, thus has better group plans since you save more using the service than AT&T.
Data Caps
Most internet service providers use data caps to keep speeds higher. When a user hits the data cap, these carriers throttle the speeds and charge more for usage above the data cap. AT&T has a 350GB data cap in its Fixed Wireless plans, whereas its fiber option has none.
With Google Fi, the data cap depends on the type of plan you are subscribed to. For Flexible plans, you get 15GB while the Simply Unlimited plan has a 35GB data cap. Finally, the Unlimited Plus plan has a 50GB data cap.
Perks and Promotions
Perks and promotions help add value to using a service. As much as we primarily focus on coverage, plans, and price when choosing carrier services, some useful perks and promotions can help sway the user’s decision.
AT&T offers an HBO Max subscription when subscribing to its Unlimited Premium Elite plan. All the other AT&T plans do not come with any perks. AT&T also beats Google Fi with its insane catalog of discounted devices. If you purchase an Android phone from AT&T, you can get up to $800 off the device, with the option to trade in an Android phone. Further, you don’t have to be a new user to enjoy these AT&T perks and promotions.
With Google Fi, you get a Google One subscription if you subscribe to the Unlimited Plus plan. However, this perk is barely exciting since a Google One subscription only costs $2/month. However, the subscription will boost your cloud storage, earn special deals, and support other Google products. On the promotions side, you can purchase the Samsung Galaxy S22 series from Google Fi for up to $300 off. Additionally, you can get a $150 discount on the Motorola Moto G series and an additional $50 bill credit.
