For future questions about this topic; I'm a Google Fi subscriber and have reached out to Google Fi support through chat which works VERY WELL and very FAST! Google Fi support confirmed this UNLOCKED Pixel 5 has the same network switching capabilities as the Pixel 5 that's sold on the Google Fi website. Network switching Google Fi phones means the phone is capable of automatically switching between the networks that Google Fi uses whether its 4G, 5G, T-Mobile (SPRINT), or US Cellular (Verizon MVNO), so both GSM & CDMA capabilities automatically whether you're in the southern or northern US territories. I define the territories because US Cellular is mainly a Northern territory network provider and you can check out both network providers coverage maps by going to their individual websites. MIND YOU; If you have Total Tech Support and you plan to protect your phone with a 2-year protection plan that Best Buy's plan is cheaper over the long run and you could probably get the phone replaced in-store faster than replacing my mail through Google FI?
