CN MI 11 supports NR band n1, n3, n28a, n41, n77, n78, n79.
All those bands are usually implemented in Asian countries.
n1 and n3 need OTA update after Chinese carriers have implemented those bands.
n28a is kinda narrow, ranging from 703MHz to 733MHz.
That's it. No fancy mmWave bands are supported.
Does flashing a new ROM modify the supported bands or is the CN phone missing required hardware to support NA bands?

Flashing a new ROM is unlikely to modify the supported bands. I assume that in order to modify it, you need to figure out how to flash the baseband...
As for mmWave bands support, MI 11 doesn't have mmWave antennas so don't expect that to happen.

Hey guys. Just to let you in on my experience with 5G, although I live in Europe, România.
Had the CN Mi 11 until yesterday. I use 2 sim cards, one from Digi, one from Orange. Digi worked fine in 5g. Although, by specs, the CN fully supports all the 5g bands needed (mostly referring to N1 for orange), I never got 5g on orange. And we have full city coverage. 4G+ also doesn't work.
Got the global version yesterday, same bands on paper, and what do you know. Immediately 5G, 4G+, everything working fine.
One more thing about the CN version. I used it both CN original rom and with Xiaomi.eu rom.
On the CN rom, the 5G icon used to appear where there was 5G coverage, but the connection itself was 4G. In the first week I didn't even have 5G activated on my sim, and it was still showing 5G. Some weird trick to induce people in error? :)
On a local forum, everyone has the same issue, CN version won't work on 5G, global yes. Same bands, I guess different modem settings. Someone flashed the global rom on it, but still same result.
So to put it short, in România, with orange operator, CN version doesn't do 5G, not even 4G+, global works fine.

Sounds weird. According to Kimovil both Digi and Orange in Romania work on the same 5g bands. But not N1, N78. And you claim that CN M11 works on Digi 5g and not on Orange 5g? Did you check with Orange what's wrong?
Unfortunately, I don't have 5g here to check myself. But 4g+ works fine.
Does someone else has CN MI11 and can't get 5g?

Sorry, maybe I confused N1 with N78. Makes no difference. Yes, one network (Digi) worked, Orange not. And as I said, not just for me, for others with CN version of the phone as well. Not much to check with Orange since the global phone, which they also sell, works fine.

Another thing that bothered me and made me sell it and get the global version, was the feedback that the CN Mi 11 didn't get 5G on orange even with the global rom, which should change the modem files as well.

Although they are under the same N78 band, It should be noted that NR-ARFCN(the number chain that corresponds to a specific frequency) range may actually be different on different versions of the same hardware. That's why Galaxy S10 5G sold in South Korea doesn't work on 5G networks of China Unicom and China Telecom even though the phone supports N78 band that is implemented by those two carriers. I assume that's the same reason that you don't get 5G on some carriers even though they use the NR band that the phone supports.

All above is my personal thoughts, the truth may differ from that.
Let me know if I am wrong.

Hola, chicos. Solo para contarles mi experiencia con 5G, aunque vivo en Europa, România.
Tenía el CN Mi 11 hasta ayer. Utilizo 2 tarjetas SIM, una de Digi y otra de Orange. Digi funcionó bien en 5g. Aunque, según las especificaciones, el CN es totalmente compatible con todas las bandas de 5g necesarias (principalmente refiriéndose a N1 para naranja), nunca obtuve 5g en naranja. Y tenemos cobertura completa de la ciudad. 4G + tampoco funciona.
Ayer conseguí la versión global, las mismas bandas en papel, y qué sabes. Inmediatamente 5G, 4G +, todo funciona bien.
Una cosa más sobre la versión CN. Lo usé tanto con la rom original de CN como con la rom de Xiaomi.eu.
En la rom CN, el icono 5G solía aparecer donde había cobertura 5G, pero la conexión en sí era 4G. En la primera semana ni siquiera tenía 5G activado en mi sim, y todavía mostraba 5G. ¿Algún truco extraño para inducir a la gente a equivocarse?:)
En un foro local, todos tienen el mismo problema, la versión CN no funcionará en 5G, globalmente sí. Mismos bandas, supongo que diferentes configuraciones de módem. Alguien mostró la rom global en él, pero sigue siendo el mismo resultado.
Entonces, en pocas palabras, en România, con el operador naranja, la versión CN no hace 5G, ni siquiera 4G +, global funciona bien.
Hello friend, if you are a root user, you should connect to pdc and see what profile the global version is using, I'm sure it uses a different one than CN if you manually change That in theory should solve the problem, it is something similar to what happens with oneplus, vivo and iqoo

    That's not what I wanted to see...I'm thinking of importing Mi 11 Pro to Europe but 5G is important for me

    That is not case - there is Carrier Policy what enables 5G-support specific Carrier. This is common almost every device sold. To make sure device work in home device, don't buy another market device.

    I have made cacombos.com website to list supported combinations. It help you to check device support all EN_DC combinations used by your network.

    That's not what I wanted to see...I'm thinking of importing Mi 11 Pro to Europe but 5G is important for me

    Think twice... Global model support more 4G and 5G combinations than Chinese model.

    It looks like that the combos used by my carrier are supported by chinese model so we´ll see i returned my Global Mi 11 today and im getting chinese 512GB 11 Ultra tommorow....but tbh i dont really care about 4G+ and 5G since i have unlimited data plan but limited to 20mb/s and the 5G drain is really high

      You can always use this website to check this (this is where I was able to confirm it's working fine in Europe :)): https://www.kimovil.com/en/frequency-checker/US/xiaomi-mi-11

      Nice - would you like contribute to me log from your device? I like to see what combinations 11 Ultra support. Instructions available in cacombos.com/contribute -> Xiaomi section.
      Will surely do when I get home
