Works

Calls and texts work over 2G, which NOS keeps running for voice now 3G is gone, and 4G data should work (shared bands: 1, 3, 7, 20).

You should be able to put a NOS SIM in the HMD 2660 Flip and make calls, send texts and use data.

We worked this out from the phone's published bands and NOS's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
