Google Fi vs. T-Mobile: Which carrier is better?

Google Fi and T-Mobile’s postpaid plans offer some of the most popular cell phone plans in the wireless industry.  Each carrier has its positives and negatives, but which offers better phone plans? Let’s put them head to head and see which brand comes out on top. 

In this article, we plan to discuss the ins and outs of both carriers and what they offer. We’ll also cover:

• What the coverage of both carriers looks like
• How prices of their plans compare to how much data you get
• The features each carrier offers for their plans 

Unsure of what you need out of a plan? Check out our guide on how to choose the best phone plan. 

Coverage & Reception

Google Fi is on the T-Mobile network. 

Google Fi is a mobile virtual network operator, or MVNO. This means that they purchase service access wholesale from one of the three major networks that own infrastructure across the country – AT&T, Verizon, and T-Mobile – giving customers service at a much cheaper price. Google Fi is an MVNO of T-Mobile. 

Often, the quality of coverage comes down to your area. One carrier’s coverage may be better in New York, while another’s coverage may be better in California. It’s important to compare between providers on a coverage map of your specific city. Ookla’s coverage map allows you to see where cellular towers are located and which company owns them. This coverage map provides information about coverage from 2G to 5G for several providers.

However, T-Mobile’s 5G coverage and access is hailed as the best coverage overall. 

Plan Options

Google Fi and T-Mobile both offer premium data. 

Like most plans you’ll see on the market, both carriers offer unlimited talk and texting options with any plan you choose. Google Fi and T-Mobile offer premium data, which does not slow down no matter the amount of network traffic. Both companies deprioritize data, meaning you’ll have slower connection speeds in high traffic areas like concerts venues and sports arenas.

Google Fi Plans

Several plans offer unlimited data with premium data at a cap. 

Google Fi offers 2 unlimited plans and one plan with pay-per-use data. Each of its unlimited plans offer a limited amount of premium data. Each plan allows up to 6 lines and renews monthly. Google Fi is on QCI tier 6 of 9.

Flexible 

This plan allows you to pay for the exact amount of data you use each month. 

Google Fi’s Flexible plan is unlike a lot of other plans on the market, as it allows you to pay a set amount per month for talk and text features. Users then pay for only the amount of data they use. After 15GB of data, your speed is slowed to 256 kbps, or 3G speeds. You can still send texts, emails, and use social media with little issues. Streaming video will be much more difficult. 

The plan also includes the ability to buy mobile hotspot data, and all plan data can be used as hotspot data. 

The plan costs $20 per month, plus $10 for each GB you use. For example, you’d pay about $70 per month if you used 5GB.

Simply Unlimited 

This plan gives you 35GB of premium data before slowing down. 

The Simply Unlimited plan gives you 35GB of premium data. Premium data means your data will not be deprioritized in times of high traffic and congestion. After 35GB, data slows down to 3G speeds. 5GB of hotspot data is also included in the plan, then stops after that allotment. 

The plan costs $50 per month. At this rate, you get 35GB at $1.42 per GB. 

Unlimited Plus

This plan is 50GB of premium data. 

Google Fi’s Unlimited Plus plan has 50GB of premium data. Connection is then slowed down to 3G speeds. You can use all 50GB of plan data as mobile hotspot data, but hotspot data stops after the 50GB. 

The plan costs $65 per month. At this rate, you get 50GB at $1.30 per GB. 

T-Mobile Plans

T-Mobile plans include varying amounts of data, numbers of lines allowed, and discounts.

Spam Protection

Customer Service 

Google Fi does not have physical stores, leaving all of their customer service to online support. T-Mobile has thousands of stores across the country.  

Google Fi is a  digital-only carrier, meaning they only offer customer support online. Google Fi offers 24/7 customer support over chat and over the phone at 1-844-TALK-2-FI. T-Mobile offers several stores across the country, and users can find the closest one with their store locator. They also offer customer support online with their website live chat, their support website for common questions, and over the phone at 1-800-937-8997. 

The Verdict

T-Mobile offers a better deal. 

For the price per GB and included features, T-Mobile offers better plans than Google Fi. With T-Mobile, you’ll be getting the same connection capabilities as well. However, if you don’t need a huge chunk of data, Google Fi’s Simply Unlimited plan is still a good deal.  

We’d recommend checking your data usage before committing to a plan.
