MI Max 3 (model M1804E4A) LTE bands?

According to official Mi Max 3 website:
LTE band support: B1, B3, B4, B5, B7, B8, B20
I just bought a Global version model: M1804E4A:
The user guide indicates band support: 1/3/7/8/20/34/38/40 (Bands 4 & 5 are missing !!??)
WIthout Bands 4 & 5 - I'm guessing I can't get onto AT&T and TMobile ?
Does anyone know if there is a code dialler to check what LTE band is being supported by Mi Max 3 ?
For folks using mi max 3 in USA successfully - may I know what is your model number?
I see 3 model variants on various websites: M1804E4A , M1804E4C, M1804E4T - anyone knows what the differences are?
Thanks !!

Screenshot from same global model. All those listed online are supported. Looks like they copied user guide from Mi Max 1/2 to save money...
For model #s nobody knows and until we start collecting data nobody will know for sure. My guess would be China 4GB and 6GB RAM, and Global. Second guess - diffident hardware variants regarding display and touchscreen, 2 each in kernel -> 4 possible configurations...

Wow thanks for your reply, how do you you get your phone to display the LTE bands? Is it difficult to do? Thanks

Question Force enable carrier aggregation outside us.

Hi everyone. Im wondering if this is possible for pixel 6 pro. Basically my unit is direct from us store which is G8VOU. Now im using it in Malaysia and 4g lte works fine.
Now im wondering if carrier aggregation is possible through root. Right now from what see through netmonster it can do 2ca on the same band(check screenshot). I think its aggregating two towers with the same band, i may be wrong though.
Anyone had any idea how to force enable multi band ca? The local sold phone can go up to 5ca which are mainly band 1, 3, 7 ,8. Thanks in advance.

I would also like to know

Is it not 4G+ an indication of currently using carrier aggregation?
Try to download NPerf app and click on speed test button. It will detect your carrier and mention it's currently on 4G+ or LTE-A
Another proof is below when you check in *#*#4636#*#* . Currently my Yoodo is on band 7 and band 3.

And Digi Malaysia only have 1 band which is Band 7

Yes like is said. Mine is at 2ca indicated that im at TWO bands aggregated. Which is way below whats possible. Let me know if you have something that can help instead of just pointing out facts i already stated in the first post. Thanks.

I sometimes have band 3 and 8 as well. Just never 3 or 4ca at a time. Only up to 2ca max.

The modem decides aggregation.
