This old Galaxy phone became my third WAN port, and it actually works

A person had a secondary internet connection set up for their home network and homelab, which would take over in case of an outage on the primary line. They were also paying for a plan on an old Galaxy phone that was barely being used. According to XDA Developers, they decided to repurpose the phone as a third WAN port.

The phone was able to serve this purpose, as reported by XDA Developers. No further details were provided about how it was set up or how it performed.

There was no apparent connection between this person's project and the release of new Samsung Galaxy phones, as Android Police reported on the success of Samsung's recent foldable phone releases, including the Galaxy Z Fold 7 and Z Flip 7 in 2025, and the Galaxy Z Fold 8, Z Fold 8 Ultra, and Z Flip 8 this year.
