As if there was any doubt, both the LG Nexus 5X and the Huawei Nexus 6P, introduced today at Google's yearly Nexus event, will be compatible with Project Fi. That makes them just the second and third phones (after the Nexus 6 from last year) to be available on Google's combination Wi-Fi/LTE mobile virtual network, which uses both the T-Mobile and Sprint networks as a backbone. Fi switches rapidly between T-Mobile, Sprint, and Wi-Fi (VOIP) for data and calls, and that little extra functionality means that conventional smartphones need not apply. You can request your Fi invite here.

Here are the one-time and monthly installment prices for purchases made directly through Fi:

We're also happy to confirm that both the Nexus 5X and 6P will work with all major carriers in the US across GSM, CDMA, and LTE, just like the Nexus 6 did. Here are the wireless bands from both phones, per the specs page on the Google Store:

Nexus 6P

  • GSM/EDGE: 850/900/1800/1900MHz
  • UMTS/WCDMA: B1/2/4/5/8
  • CDMA: BC0/1/10
  • LTE (FDD): B2/3/4/5/7/12/13/17/25/26/29/30

Nexus 5X

  • GSM/EDGE: 850/900/1800/1900MHz
  • UMTS/WCDMA: B1/2/4/5/8
  • CDMA: BC0/1/10
  • LTE (FDD): B1/2/3/4/5/7/12/13/17/20/25/26/29

Those bands cover AT&T, Verizon, T-Mobile, Sprint, and US Cellular, both 3G and LTE, so an unlocked phone from the Google Store will work on all of them with a compatible nano-SIM card. More exotic services like Republic Wireless are not included. International models of the 5X and 6P may vary slightly, but since the odd CDMA/GSM split in the US isn't present in most of the rest of the world, it's not a huge issue. Treat the new Nexus phones like any unlocked GSM-LTE device.
