Guide needed to enable LTE-A/LTE+ on violet - Xiaomi Redmi Note 7 Pro Guides, News, & Discussion

Xiaomi says redmi note 7 pro supports 3ca but hardly is anyone experiencing it. Some internal digging made clear that it does support 3ca but its not compatible with the Indian networks yet(don't know about other countries). Most of the users report some sort of network/speed problem on lte. I read a guide here on xda for enabling LTE-A on xiaomi mi a1. Was wondering if anyone could make a dedicated guide for note 7 pro too. Well xiaomi too could fix the issue but seems they show no interest and don't even address it publicly. The network on this thing really sucks, it does. And that shouldn't become the reason to hate on this lovely device.
Don't understand what I am talking about, read this - https://piunikaweb.com/2019/04/25/e...ion-likely-incompatible-with-indian-networks/

My area supports 1800+850+2300 interband ca by Jio. But no signs of its support by rn7 pro. Even while traveling I didn't notice 4g+ anywhere. And yeah the network in my area is very weak.

Can't do an anything for now buddy. That's why I made this thread requesting LTE-A support for rn7 pro. Seems that cant be done too. Only hope is if xiaomi adds lte+ support over ota itself. But for now they seem to struggle to fix even the basic bugs.

Well my concern is not speed but poor network coverage and no support for carrier aggregation. Well even about speeds I get from 0-150 kbps, at night around 1 mbps but only in a particular region in my house. But these speeds are not constant, for a second I get good speed and the next second I get none, 0. The issue with me is more of a coverage related than speed related. Though with support of 4g+ things would have been much better.

About your speed issue I think your carrier is the culprit. Are you getting slow speed issues on other devices as well with the same carrier ?

Well slow speed isn't an issue that I heard of. Network coverage and lack of 4g+ is the issue we all are facing. Are you sure all your network settings are fine like data roaming on, volte on, selection of correct apn etc.

Check which band your phone is connecting to. Download network signal guru and connect to Band 40. Requires root.

Where is this folder bro. Also, we do get 4G+ for airtel in RN7pro.
Update: Found the folder. I don't think you can enable it like that.

Disable 4G/H+/HSPDA & force 3G

Hi,
Does anyone know how to enter the secret menu to disable H+/HSPDA and force the phone to use 3G ONLY? I'm on the latest Russian official rom and the codes I've found online do not work anymore.
Anyone managed to do this? thanks.
Type *#*#4636#*#* in phone.apk and then select phone info and choose WCDMA only.
I think this worked on older roms and not on the latest 4.3 one. which firmware are you on?
The option to choose WCDMA or GSM only is in settings, more networks, mobile networks, network mode.

Ok let me explain correctly..When i choose Wcdma, then the phone switches to H and H+ constantly when in low reception places and connection is sometimes lost. That's why I am looking for 3g only since 3g signal is better where I live.

They are definitely not the same thing and it seems you've never used the secret menus to switch from 4g to 3g..Ok lets stop here. I wanted to permanently change the NETWORK BAND to 2100 ONLY. It seems this is not possible on the S3,otherwise people would already have done it like in past samsung phones.

4G and 3G are different, but your phone doesn't have 4G anyway so that's irrelevant.

Just to let u know, you could fix the frequency in the secret menu as I did this many times, whereas I don't know the codes to get there as well, they were changed I suppose. In addition the i9300 only got up to H+, no 4G, if I am not wrong, H+ is 3.9G, H is 3.5G.

Still, before such a drastic solution, have you tested different modem (even older ones)?
It can make a huge difference.

Does Moto Z(unlocked) support: VoLTE, Band 12 and possibly WiFi Calling on T-Mobile?

Hi! Any one uses or used Moto Z on T-Mobile and can confirm VoLTE, Band 12 and maybe WiFi calling?
I can confirm that Band 12 is supported as that's all I get where I live. It appears to have VoLTE as there's an option to enable "Enhanced 4G LTE Mode" which has a descriptor of "Use LTE services to improve voice and other communications (recommended)." Also, I believe one of the requirements from T-Mobile for unlocked devices to use Band 12 is VoLTE capability in order to access E911 services. There's no wifi-calling on the unlocked model.

Thanks for the info! Some of my other phones although did have VoLTE in the settings as you described above, but that feature never worked.
1) So Band 12 is there
2) No WiFi Calling
3) As for VoLTE, could you check if it is really working? Disconnect from wifi, make sure LTE indicator is showing and try to make a call and see if your LTE indicator is still showing or it has changed to a lower indicator 3g or 4g.

VoLTE definitely works. I can hear it when I call people who have T-Mobile because it uses "HD-Voice". It's a shame about the Wifi calling, but you won't find it on any phone that T-Mobile doesn't sell directly because they need to have custom builds of software in order to function. I think it should be a lot easier to enable with just a Wifi APN or something, but maybe that is coming in the future. Also the Wifi calling was honestly buggy as hell on my S7E, it would echo, mute one of the callers, not transfer to LTE when I left range, and video call would freeze.

Hello
since i have unlocked the bootloader.... i cannot use VOLTE calling but i can still access the LTE services (Jio SIM)
any help for enabling VOLTE will be much appreciated

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Honor 8 Pro's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.
honor needs to do more with local telcos to enable features like 4g+ and VoLTE. Where I live now, I can't enjoy these yet though my telco does offer it to other phones like Mate9 and even P9.
Lte signal is good and even performance is excellent but volte calls dialled from this phone to other volte number doesn't work.

4g, LTE Network is good on sim 1 but the reception on sim 2 fluctuates too much even in the centre of the city where you expect maximum network connectivity.
Speeds on 4g are terrible, literally. Youtube struggles to stream video at 360 on 4g with good connectivity. If the connectivity is low, stop even thinking to load a webpage.
Other thing is if you switch the default mobile data to 2nd sim, it will switch 4g to 2nd sim making your sim 1 obscure if it is a 4g only network.
Also there is no way you can lock your network to 4g/3g/2g only. It floats between the 3 techs.
And last the Jio VoLTE calling issue where you the call disconnects immediately.
The phone doesn't support ViLTE.

sadly, how telco implements things like VoLTE, 4G+ (CA), etc... it's not as simple as just meeting band requirements.
as such, in Malaysia, one cannot get VoLTE and CA on any of the local telcos. hopefully, honor/ Huawei can work with the local telcos. after all, phones like P10, Mate 9 all have VoLTE working with the local telcos.
but that aside, speed is decent. i guess this depends on the telcos... whether their network is saturated or not, etc...

Yup, not as easy as we users think.
BTW it also supports carrier aggregation but this has to be supported both by device and the network.
Fortunately, in India. It's supported by both.

you're lucky... honor India seems to be very strong and active, unlike honor Malaysia where they just launch the phone and then just leave it as it is after that. rather than work with telco to enable ALL the capabilities of the phone (like VoLTE and CA), they are just focusing on marketing it as a gaming device -- partnered to sponsor Mobile Legends Championship in Malaysia.
they actually mentioned on a FB post that honor 8 Pro does not support VoLTE. quoting them:
Honor 8 Pro does not support VoLTE. However, we will take your concern as suggestion and highlight this matter to our relevant team for their attention.

Thank you for contacting Honor support.
This email is in reference to concern regarding network issue in Honor 8 Pro. We value the importance of information requested by you and we are happy to assist you.
In response to your query we would like to inform you that Jio sim only works with 4G network it will not work with 2G/3G network and at a time 4G network will work in one sim then another sim network will convert into 2G network.
Further, we are forwarding your precious feedback to the concerned department and we will try to work on it in our future update.

And now exactly this is the thing that I am trying to explain them but this is what they are replying!
That the second network converts to 2g but then you cannot just stop mobile data of sim 1 and switch on mobile data of sim 2 because that will change the 4g network to sim 2.
Quite dumb!

[Resolved] Every custom ROM has LTE signal drop

Every custom ROM for Redmi Note 4 SD has a bug that is making LTE signal disappear, you can verify it by opening signal info in settings.
You can see that the dBm signal stay at normal value but "asu" value is constantly spiking to "99" which causes signal indicator to show no signal for brief moment.
This happens for every ROM that is not based on MIUI.
Does anyone know what is the cause of it? We have sources released, is this a kernel issue or something else? It cannot be modem firmware since we are using same as MIUI. Can this be diagnosed/fixed ?
I remember it was the same few months ago, and still nothing has changed. I think it's the biggest issue and im wondering if anyone is trying to work on it.
Edit:
Best explanation: https://forum.xda-developers.com/showpost.php?p=76811230&postcount=157
I will mark this as resolved.

LTE and data are of course always enabled on my phone.
The only moments where I lost LTE signal is when I drive and arrive at a place where there is no LTE signal.

Every custom ROM for Redmi Note 4 SD has a bug that is making LTE signal disappear, you can verify it by opening signal info in settings.
You can see that the dBm signal stay at normal value but "asu" value is constantly spiking to "99" which causes signal loss (no signal).
This happens for every ROM that is not based on MIUI.
Does anyone know what is the cause of it? We have sources released, is this a kernel issue or something else? Tt cannot be modem firmware since we are using same as MIUI. Can this be diagnosed/fixed ?
I remember it was the same few months ago, and still nothing has changed. I think it's the biggest issue and im wondering if anyone is trying to work on it.

Yeah. It can be solves, if it's showing wrong signal level
This doesn't look like a cosmetic defect. I was on MIUI Nougat and didn't face any issues with signals. After coming to RR Nougat, I can see frequent fluctuations in network. Lesser speeds, much less consistent connectivity. I have tried changing the sim, compared with a phone running MIUI on the same sim, there is an undeniable fluctuation, with intermittent loss of data. This seems to happen only when data is enabled.

Yes, worth mentioning is that the issue is with LTE (4G) with Data enabled, i didn't noticed any signal issues or disconnections using 3G with Data enabled. Someone smarter should look into this.

50Mbit speed limit?

Hello,
I am running latest LineageOS. I can't seem to get more than about 50mbit on 4G (with ookla speedtest), with same SIM card, on an iPhone7 I get about 150mbit consistently at same location. I am not sure if this is related to 4G+/LTE-A not functioning. I see only LTE text on the top bar.
In another note, a friend of mine is running original OS and he says he gets 50mbit on wifi with max2, with his iPhone7 on same wifi accesspoint he gets 80-90mbit. (he couldnt test 4G because of bad signal quality in his location),
So, first of all, how can I tell if my phone is using 4G+/LTE-A or not? Do you get better 4G speeds?
How can I test where is the bottleneck exactly? Any hints?
Update:
I now made more tests. Cheap Chinese tablet with mtk6797 chip does about 100mbit in the same location.
At home I tried 5g WiFi and when phone said 433mbps, the download speed from samba server was about 48mbit (server is connected to wifi ap directly with gigabit Ethernet)
Thanks!
Noop, I am on T-Mobile, 100m+ on band 4 all the time
@cgigate which max2 model you have? which OS are you using? and which modern/baseband version?
My provider use band 3 but I don't think it is the issue. Because I get similar result with WiFi which is very strange. Also, do you see LTE+ or something different than LTE as connection icon?
@cgigate I think you must be sitting next to antenna all the time. I managed to get 80mbit when base station antenna was 50m away from me and I was very close. My provider use B3 and B7 which should be supported with any version of max2....

I own two MAX 2 (x820 and X829), both are same on stock 23s.
yes, my house near a good t-mobile towers for sure ...especially on band 4, sometime on band 2 or 12 , those bands are much slower...
@cgigate can you check my previous post? I had some questions for you there how do you see which brand you are on?

You cannot see the band actually. You know the band you are on by knowing what your network provider uses.

Use LTE discovery APP and turns on "Live" mode you will see the real-time which band you are on, see my screen capture you will know I am on LTE band 2

Do you need root ???
I use the same app on lineageos and it needs root.
But I am not sure still why my max2 is performing so bad.
Anyway, I downgraded my service connection speed to 21mbit now and have no more speed problems I think there is some sort of problem in max2 which is causing this.

No root needed for "LTE discovery" app to get band info

No, "LTE discovery" app dose not need "root" to get RF band info on lineageos
although, there is option to choose "root" from the app to get more info. but if you only want to know what band you are on , no "root" needed
@cgigate if I dont select the root option. It only shows me the signal strength. I don't quite understand how everything works for you and nothing works for me lol.
See the screenshots with it selected and not selected. I also attached one from phone info...you tell me if anything is different? I really dont understand how this can happen....
@cgigate can you send screenshot from your phone info? or what os are you using and what is your baseband modem firmware version?
