Is Google Project Fi the Best International Data Phone Plan?

Google Fi is a popular mobile virtual network operator (MVNO), leasing cellular spectrum from Sprint, T-Mobile, U.S. Cellular, and, in the UK, Three. Google Fi works with selected devices capable of switching on the fly between multiple cellular networks as well as Wi-Fi networks.

Excellent Signal Reception

Among these devices is the new Pixel 2, the original Pixel, the Android One Moto X, and others. Because Google Fi-supported devices always connect to the network that provides the best signal reception, Google Fi customers barely know what dropped phone calls are, and their idea of what the typical mobile Internet speeds are is very different from those customers who are tied to the network of a specific network operator, such as Sprint or T-Mobile.

Besides the ability to make calls and send text messages over Wi-Fi, which comes in handy in densely populated urban areas or underground, Google Fi customers can also turn their smartphones into convenient mobile hotspots that can be tethered to other devices.

Affordable International Calls and Texts

All of this for only $20 a month for unlimited domestic calls and texts with 24/7 support, with international calls and texts to over 135 destinations included in the price. More specifically, “Unlimited international texts are included in your plan. If you’re using cell coverage, calls cost 20¢ per minute. If you’re calling over Wi-Fi, per-minute costs vary based on which country you’re calling and you’re charged only for outbound calls,” as states Google Fi’s official FAQ page.

Pay Only for What You Use

Because no smartphone is complete without mobile Internet access, Google Fi offers 1 GB of mobile data for just $10, and customers get credited back for data they didn’t use. In practice, you estimate how many GB of data you are going to use and pay for that amount. If you pay for, let’s say, 2 GB but use only 1 GB, Google is automatically going to roll over the difference from your pre-payment to the next month. And if you would also like to use your mobile data on another device, you can get a data-only SIM card for free and buy data for the same $10 per GB. Should you ever decide to move to a different mobile operator, Google isn’t going to charge you any early termination fees.

Family Members Welcome

If you discover that Google Fi gives you much better signal strength while costing you less money than your previous plan, it’s only natural that you might want to add other people to your plan and share your data with them. With Google Fi, you can do just that for only $15 per each person added, and you can add up to 5 people in total.

According to our experience and customer reviews, call quality with Google Fi is consistently excellent regardless of whether the call is domestic or international, or whether the calls takes place over Wi-Fi or over a cellular network. Depending on how good the speaker in your smartphone is, you might be able to hear a minor difference between Wi-Fi calls and cellular calls (with Wi-Fi calls having slightly lower quality), but we don’t expect most people to even notice.


Google Fi has established itself as the best mobile virtual network operator for those smartphone users who rely heavily on mobile data but also are no strangers to international travel and don’t want to go through the hassle of getting a new SIM card from a local mobile operator just to stay in touch with colleagues, friends, and family. The only major disadvantage of Google Fi is the need to own of the supported smartphones, instead of being able to use any Android device.
