Someone correct me if I'm wrong, but they're aiming to serve the EU and UK (and Norway and Switzerland) markets only. Although, with that said, the page for the September 2026 phone says this (https://commerce.jolla.com/products/jolla-phone-sept-26 https://commerce.jolla.com/products/jolla-phone-sept-26): > LTE FDD: 1, 2, 3, 4, 5, 7, 8, 12, 17, 18, 19, 20, 25, 26, 28AB, 66 > LTE TDD: 34, 38, 39, 40, 41 > 5G NR: n1, n2, n3, n5, n7, n8, n12, n20, n26, n28, n38, n40, n41, n66, n77, n78 But I have no idea if that means it'll work for you in the US/elsewhere.

> But I have no idea if that means it'll work for you in the US/elsewhere. Yeah, that's a fun part of the crazy bandplan for lte/5g where it's just a little here and there without global coordination. But a look here [1], says it has all 5G bands for AT&T, 2/4 bands for TMo, and 4/5 for Verizon. Seems maybe a bit iffy for TMo, one of the missing bands is n71 (600 MHz) which is extended range that helps fill in coverage.

  Also missing Band 13, which is Verizon’s main band for coverage

  Why aren't modern SoC modems just support all bands? How hard is it?

    Just a guess: maybe it requires fairly expensive certification that is not worth it when a SoC family is barely used in a region (yes, I know, chicken-egg).

    It's not only the issue of SoC modems but about the whole integration (RFIC, LNA/PA, RF switches, antennas...). The more bands you integrate, the more difficult it becomes (or with compromises such as worse performance because of wideband antennas...). If I may risk a comparison : you can't have a lense with a huge focal range that would simultaneously be perfectly sharp and have a wide aperture like fixed focals...

  Some carriers also require your phone to be on their whitelist - for example AT&T. And Verizon claims they don't do it that way, but we had a phone that worked on Verizon with an old SIM card until Verizon caught on, and then suddenly it wasn't compatible with their network and couldn't be used on Verizon.
