4G Network NOT accessible on MI5 PRO 128GB

I am in a country where all Network Operator uses Band3 (1800Mhz) for LTE. And i have search everywhere and it is clearly mentioned that mi5 pro do support lte Band3 and yet i can seem to be able to connect at all!
I am using China Stable version 7.5.6 and yet just cant connect at all to the LTE Network even when i manually tries to search and register to 4G Network, it just goes to No service then Emergency Calls only. :crying:
Hope anyone can help me out with this as i find it very sad that i cant use 4G in my country.
I have already tried several times to change stuff on the *#*#4636#*#* menu but still it just does the same thing. i have sims of all 3 operators and yet none of them connects to the 4G networks.

Maybe add the APN and turn on data for the sim you're using?

It should certainly work as I'm with Three who operate on 800 and 1800 and 800 isn't supported but I still receive 4G signal. As mentioned try manually adding the APN for your network?

I don't have the 'prefer LTE' option under mobile network but still can connect to LTE network in my country (1800Mhz), this happens for both china stable 7.5.6.0 and global stable 7.5.2.0 ROM

Can you update to lastest Xiaomi.eu version (Miui 8) and check the 4G on that 1800band?

Xiaomi's/MIUI's Network Band Prioritization

Hello guys,
I'm using Mi9T Pro with Stock EU rom MIUI 12 version 12.0.4
I have this issue with Xiaomi regarding how the system handles prioritization of Network Band when it comes to using Mobile Data connection.
We know that we have options to prefer 4G, 3G or 2G. But it doesn't define which specific band. Like for example, 4G can be 4G/LTE or 4G+/LTE+. These 2 networks seem to be the same but these actually have different network bands
The question is how does Xiaomi system prioritize which band to select?
Does it prefer the one with higher signal or the one that pings better.
I have this question because as I have experienced, Xiaomi system seem to prefer the one with better signal regardless if it can't even pull any data. In short, it will keep connecting to a network with a better signal strength even if you won't get any internet connection out of it.
I've been noticing this when I set my phone to 4G preferred in my location. When signal indicator turns to 4G/LTE. It may seem to show you that you're connected to the internet but you can't really browse anything because there's actually no data for that band. But when it turns to 4G+, that's when I really get to connect to the internet.
And the biggest problem is that the system prefers to connect to the 4G band. That's why I'd prefer using 3G network because I have a more stable 3G+ signal here.
Another thing that's really disappointing is that my other phone OnePlus 5T handles this well. We share the same APN.
Sadly there's no band selection in *#*#4636#*#*
It would be glad if anyone could provide a better solution to this.
Thank you!

4+ g usually means (specially on Xiaomi phones) LTE Advanced Carrier Aggregation where no other/different bands are used but instead the phone is in parallel attached to more than one 4g band. As such, it increases the speed (and maybe, in your case provides a fail-over?!):
https://www.gizbot.com/mobile/featu...ifference-between-4g-4g-explained-053769.html
However, there is another question why (on that place) you have strong 4g signal with no Internet, so that when your phone switches to CA and in parallel attaches to another 4g band (maybe with a weaker signal) it obtains Internet connection over that second band
At least to better understand on which band (at which place and which base station) you have a 4g signal but with no Internet connection, install an app like Network Cell Info Lite, LTE Discovery, Net Monitor Lite). I think with Net Monster (all apps are on Playstore) you can even see on the map where is the base station you are attached to
If your phone is rooted, you could use Network Signal Guru that will show you, in case of 4+g all bands you are aggregated to with their signal strengths, base stations locations, etc (apps above would always show just one, primary band):

Ohhh thank you for this explanation.... Someone actually mentioned aggregation to me also. This helps make me clear up how Xiaomi does this and that. Does this mean force selection of network band won't work on Xiaomi devices?

I'm pretty sure that with MIUI 11 there was an option to disable/enable 4+, but on MIUI 12 (12.0.2 QFJEUXM) there is no more that option
I don't know of other options (except to prefer 4, 3 or 2 g), specially about selecting bands

choose band mode

Download activity launcher (play store), run it
Search band mode ===> Set radio band mode
Choose band mode you need

Standalone 5G on T-Mobile USA - problems with switch to LTE in areas of poor SA 5G coverage

Since the Feb update, the 4A 5G works on standalone 5G (which doesn't require a simultanous LTE connection). For many place, on T-Mobile, that is 600Mhz for SA 5G which gives better signals inside buildings.
But I've noticed that outside, in areas with low signal for 5G, I get really poor connections, but if I go into settings and switch the preferred network ttpe to LTE from 5G, I have no problems.
Has anyone else noticed similar problems where the phone becomes unusable on 5G and won't switch to LTE?
You can tell if you are on SA 5G if you go Settings->About Phone->SIM Status and you'll see "NR SA" for Mobile voice network type and mobile data network type (see attached JPEG). (if you are on "non-standalone" 5G those will probably say LTE and "NR NSA".
I am wondering if the sensitivity for switching from SA 5G to LTE isn't set correctly - hopefully they will fix this since it's annoying to have to manually switch things (and impossible to do that if driving).

Question Mi 11 ultra no 5G cellular network [ stock global ]

Hello everyone,
I've just upgrade my plan to have 5G support, but the phone does't pick it up ( the carrier says it's ok )..
I also searched manually for networks and I find every network even from other provider but NOT a single one with 5G.
obviously I am in a 5G area, center of Milan, and sim slot 1 ( but I recall that was dual 5G, no? )
It's a bug, broken or I played with some setting disabling 5G?
thanks
EDIT: SEEMS LIKE THAT switching preferred types, airplane mode, while outdoor made the phone to connect t o a 5G antenna...
funny note, it's slower that 3g: 5.69mps/0.59mbps

Might need to enable it

you mean preferred network type? always been in 5G

Try to reset apn configuration and all kind of connection, then switch off the phone for 1 minute and reswitch it on

If you have the chinese model (not EU or global) you might have some 5G band limitations, and it's also to be taken into consideration which bands your operator is using in your area.

Question Any way to get 4g+

Is there any way to get 4g+ on redmi note 11 spes
And also does 680 supports carrier aggregation
If yes then how many bands i.e 2 ca or 3 ca

I have a redmi note 11 with 4g+
It will depend on your SIM, company and signal that arrives at that moment.
For example, in my house I have constant 4g+, but since I use Wi-Fi most of the time, it is not important.
At work it only takes in H+
