Xiaomi Redmi Note 7
After looking in Kimovil all the configurations for the Redmi Note 7, I can tell you that there is a version with the B28 band. It isn't the Global one, nor the Chinese one, but the India/Taiwan/Malaysia/Polony one!! Here you have an screenshot:

Sorry but kimovil is the manufactur.
Trust mi.com! If They say global has band 28, than it has.
I have the global one, but No 28 LTE to Test it

Trust the manufacturer site, OK but the webpage doesn't mention which version/variant is described...

There are three models of Redmi Note 7, each one in différents variants (storage, ROM,...).
- M1901F7G : Global model, distributed through European Mi stores (including in France where B28 have been starting to be deployed), amongst others. B28 is NOT enabled. B20 (the main LTE band in Europe so far) is enabled, though.
- M1901F7H : Model with different versions/variants including some delivered with CN ROM (China) and others with APAC ROM (Asia Pacific i.e. Taiwan, Malaysia, Indonesia,...). This model has certification for B28. But only the APAC variant actually does have B28 enabled. On CN variants, there is no B28.
- M1901FYI : Indian model. No B28 here.

After looking in Kimovil all the configurations for the Redmi Note 7 said:
Beware! ID stands for Indonesia, not for India! Indian model is pretty different in terms of LTE bands. Also, PL actually seems to refer to Poland but this information is really weird since B28 has not been deployed in Poland and Xiaomi sells the Global model with Global/EU ROM in European countries where they currently focus on (Spain, Italy, France, this latest already using B28). A non sense, then... I don't know where this information come from.

Foxy, for what purpose do you need B28 (which network)? :confused:

Per the specs, it's obviously the APAC variant. It's a good move from Gearbest who meet the requirement of some Eurogeeks desperately seeking for a cellphone having both B20 and B28 enabled (subscribers the Free network in France). It may even not be a will from them, since they don't offer the M1901F7G anyways (only the CN and APAC variants then). Since the CN version is a real no go for EU customers, the APAC variant is just a perfect alternative as long as it offers all languages. And it is very probable the APAC variant natively includes multilanguage.

Thanks for the precisions!
So at the end (at least for european use) better go with the M1901F7H (APAC) as it has the 48Mpx camera and the B28 in bonus.
Question:
As i'm planning to root later, will there be restriction for B28 on Xiaomi.EU, MiGlobal or future Custom ROMS on this M1901F7H model?

It's what it looks like. I just asked Gearbest to confirm the model number. I will let you know if I get an answer.
The number of bands enabled on this models is impressive. It's not only the B28. This variant also have B2 and B4 which is pretty useful when travelling to the American continent! And none of the "Global Version" bands is missing on the APAC version. If this is confirmed, it's a shame that Xiaomi sells a so-called Global Version in official store although there is another regional version which is truly usable worldwide. Now I feel fooled after having bought my Redmi Note 7 in an official MiStore. :(

I don't know much the Xiaomi services you talk about but for the custom ROMs I don't see any problem as long as you use a custom ROM designed for the appropriate model (H in this case).

Edit: After further research, I couldn't find any track of an APAC version managing the B20... The Gearbest description seems to be copied-pasted from the Xiaomi global website herebefore linked. However this page list the specs of all the different versions together as one, which is pretty misleading. Better wait the clarification from GB, then...

There's also the 128Go version with the same LTE bands listed.
https://www.gearbest.com/cell-phones/pp_009560908387.html?wid=1349303#goodsDetail
Is it the same H version with just bigger internal storage? (looks like...)

EDIT: interresting post on this forum:
https://forum.hardware.fr/hfr/gsmgpspda/telephone-android/unique-redmi-note-sujet_32992_16.htm#t2428695

Xiaomi has on global site different bands than in FR and ES sites, and also on IT site has different bands from all of them.

Global: B1/2/3/4/5/7/8/20/28
ES: B1/2/3/4/5/7/8/20 (a few weeks ago ther was not B4 on Spanish site specs).
FR: B1/2/3/4/5/7/8/20
IT: B1/3/5/7/8/20

AFter checking again FCC certification:
https://fccid.io/2AFZZ-RMSF7H/Lette [...] er-4142497
And a unit bought by me in spain, i see that Spanish version is the M1901F7G and that does not have B28, and after checking all mi sites, I see that only some countries has B28:

· Indonesia
· Malaysia
· Poland
· Vietnam

So for this countries they have M1901F7H with B28. I have updated bands on Kimovil site, is hard to find real bands and we have not found any shop with B28 version :(

indonesia MI specs shows B20 B28.

Same as the official Taiwanese store :
https://mobile.mi.com/tw/redmi-note-7/#specs
And with these LTE specs, it comes in two variants 4GB/64GB and 4GB/128GB (no 3GB/32GB like for the Global Version nor 6GB/128GB) exactly like the two options offered by Gearbest.
So yes, this phone with both B20 and B28 and much more exists. The remaining question is why Xiaomi made a so called Global Version that is way less global than this one? Is it just to save few dollars on European's customer account? :-/ Or for certification reasons?...

i "love" the Gearbest answer:

Your original question is "Can you confirm it is the M1901F7H global version?"
Here is the answer from Our Customer service Team:
"
Dear Zedoc,
Thanks for your request.
It is Xiaomi Redmi Note 7 4G Phablet Global Version.
"

Totally contradictory with the description... It says much on GB's reliability. :-/
Let's see the positive thing. At least you got a reply. I'm still waiting mine.

From what I find online, the only variant that has B28 is M1901F7H. It is sold in Taiwan and a few other APAC countries like Singapore.
 
I have a RN5 with H at the end in model number (taiwan version). Shows B28 with LTE Discovery, but most of the time it shows B2. My operator uses both. Just tried G ending RN7 Global and only shows B2, no B28, tried several times. Even in moments when my RN5 showed steady B28, switched sim card and no B28 in RN7. So it seems like it's not supported. Just opened dispute with AliExpress, on the listing it showed B28.

None of the sources that say the "G" version lacks B28 is believable. They mostly get the information from the User Manual, which does not list B28 (but that could be an error since it was probably copied from another version of the manual).

The only definitive way to test is to find out which towers are carrying B28 ONLY for 4G for your carrier/operator. In Australia we have a website called oztowers.com.au that allows us to do this, you probably have one too.

Find a tower that only has B28 for 4G for your carrier, and travel to it. Park next to it and see what happens.

There is little confirmed information about B28 and it is confused.
Several stores in Aliexpress are listed as B28 in the description of RN7. However, the review image posted by the buyer is M1901F7G.
Are the descriptions of these shops false?
I asked a few shops about B28, but the shops only replied "This is a global version".

    Only been getting b3 showing up in the couple of places I've checked. Although the same is happening with my galaxy s7 (has b28 support also).

    edit: had a look at my network operators 1800/700 LTE coverage, and it looks like i have to get out of town to get into only 700mhz areas. Might try that later this week. ??

    edit 2: on actual inspection of the phone/manual turns I've got the M1901F7G variant, unfortunately for me, this doesn't have B28. Had a word with PBTech and they have M1901F7H. So if you're after B28, make sure you're getting the H variant.

    Ok I have the correct facts now. See on FCCID:
    https://fccid.io/2AFZZ-RMSF7H/Letter/Cover-letter-4142497

    Resuming:
    M1901F7G (Global) have less bands (including B28-700Mhz) and M1901F7H initially sold for APAC regions and now is APAC+LATAM (Latin America).

    Yes, that is correct, and I haven't found anywhere to get M1901F7H even though I am in apac region, but I was hoping they used the same radio hardware on the G and H but just turned off B28
    Though in my testing I still can't verify one way or the other, changing the NVRAM has saved successfully, but something else overrides it.
    I have tried disabling B3 but the phone ignores the setting. I have verified it's saved in NVRAM via QXDM, but the phone isn't taking notice of the setting changes, any other suggestions as to where the OS might override this setting would be nice...

    EDIT: okay, I read that whitepaper properly... saffB780MAA0F0AR component added to M1901F7G to provide B28 functionality for the M1901F7H
    Ah, sad that I was sold the wrong model and GearBest wouldn't say if they can replace with H version and I since scratched the screen, so no returns, I'll just have to cope for now...
