Google Fi, previously known as Project Fi, is an MVNO cellular provider that uses T-Mobile's expansive network infrastructure to deliver reliable 4G and 5G coverage across the nation. However, even with such a robust network foundation, many Google Fi users experience cell signal challenges. If you’re one of them, you’ve come to the right place. We’ll be going over what may be hindering your Google Fi service and how cell phone signal boosters can help enhance it.

Why is Google Fi Cellular Service Weak?

Google Fi cell signals travel over the air between cell towers and cellular devices. Cell signals are strongest at the source. The further they travel the weaker they become, leading to poor cellular service. In addition, obstacles in the signal’s path further weaken reliability.

Factors that weaken Google Fi reception include:

  • Cell Tower Distance - Proximity to your closest cell tower servicing Google Fi significantly impacts signal strength.
  • Building Material – Metal, concrete, brick, and other materials can obstruct signals, contributing to weakened Google Fi reception indoors.
  • Nature’s Elements – Trees, hills, mountains, and the like act as barriers, causing signal degradation impacting the reliability of your Google Fi service.

How to Improve Your Google Fi Service

There are many troubleshooting tricks you can try to boost your Google Fi service. Some examples include restarting your phone, ensuring you have the latest updates, and toggling airplane mode. In some cases, applying these tricks works. However, results are usually temporary.

Cell phone signal boosters for Google Fi have proven to be a more reliable solution. They take your existing 4G LTE and select 5G cell signals (even if weak due to the factors mentioned above), amplify them, and rebroadcast them inside buildings or vehicles for better connectivity.

All Google Fi cellular devices within the cellular booster's coverage area will instantly receive better signal. The occurrence of dropped calls, failed texts, and slow data in the places that matter will decrease or disappear. Read our guide on how signal boosters work for more information.

Can’t I Just Use WiFi Calling When Google Fi Service Is Weak?

WiFi calling is a great way to get around spotty Fi cell service inside your home. Though, it does have its drawbacks.

Using WiFi to make calls puts great stress on your WiFi network. If you have inconsistent WiFi signal, it can be made worse. If no WiFi is available, or if it cuts out at any time, you are in no better position than before.

For the most consistent Google Fi cell reception we recommend a cell phone booster over WiFi calling.


Will a Google Fi Signal Booster Also Improve My Mobile Hotspot?

Yes. Mobile hotspots and cellular routers use cellular signals to provide wireless internet connectivity. Performance will improve with stronger cell signals.
