T-Mobile and Project Fi are both masters at WiFi calling, and cellular-to-WiFi-to-cellular handoffs. Not to be outdone, Republic Wireless wants to master this art, as well.
While the Sprint MVNO already has the ability to seamlessly switch a call from WiFi to cellular, customers can’t switch back to WiFi calling until they end a call … or until their call gets dropped. This can obviously get very annoying if you routinely start calls somewhere that has good cellular coverage, only to enter a building that is a cellular black hole but has excellent WiFi throughout (like my own workplace).
Republic Wireless calls this Project Salsa, and interested customers can sign up to help this in Republic Labs. According to the company:
This project is super easy too. Once enrolled and activated, all you’ll have to do is make calls (preferably on or near WiFi). And report your feedback. We’ll be periodically asking you to record your overall experiences on surveys. We’ll also have a form open to collect any specific experiences, thoughts, or comments you have. That’s it! That’s all it takes to put all our members on the path to staying better connected!
