After a lot of whispers circled around the web, Google officially launched its wireless carrier effort known as Project Fi in the US this April.

However, there’s a major caveat related to Project Fi. For starters, Google is doing things at a small scale, so only owners of the Nexus 6 or those willing to purchase a Nexus 6 are eligible to try out the new carrier service.

On top of that, Google is relying on third-party infrastructure from Sprint and T-Mobile in order to deliver its services to customers.

That's why, other Nexus users might have felt frustrated with Google leaving them out of the whole Project Fi affair. Luckily, developers and tweakers have struggled to find a way to allow other Nexuses to have a taste of Google’s mobile virtual network operator ventures.

The Nexus 5 gets Project Fi treatment, unofficially

User Robpol86 on the xda-developers forums claims he has identified a way that lets users of the Nexus 5 take advantage of Google’s Project Fi, too.

He states that outbound voice calls and LTE data are working. However, he says he is worried about international roaming on Sprint/Tno/Wi-Fi calling handoffs and has not been able to verify how it works until this hour.

If you’re wondering how he managed to activate the service on the Nexus 5, Robpol86 is willing to explain this feat. He says he activated his Project Fi SIM on a Nexus 6 device and everything was working smoothly from there. Then, he bought a nanoSIM-to-microSIM adapter and put the activated Fi SIM into the Nexus 5.

Afterwards, he proceeded to factory wipe the Nexus 5. When that was done, he set up his gmail account and other settings over Wi-Fi and installed the Project Fi app and opened it. The app immediately activated Project Fi and offered cell service. Since then, everything has been working pretty smoothly on the Nexus 5.

Last but not least, we should mention that the user has the Android M developer preview installed on his Nexus 5 device.
