It seems all operation with cellular data modem is not woking on this phone:
csd internet is not working,
c++ function RasDial, RIL_dial not working,
applications that can work with modem - vxhpc, mtoken (www.choung.net) is not working
Is anybody successfully use any from this list?
I have try all of this on two i900 with different software versions
Most carriers to date have chosen not to enable CSD functionality while connected to 3G services.
try set your network BAND selector manually to “GSM” by using the following procedure:
For Windows Mobile Communicators (Pocket PC):
1. Select “Start” -> Settings.
2. Under the “Personal” tab select “Phone”.
3. Select the “Band” tab.
4. Under “Select your network type.” Choose “GSM”.
5. Choose “ok” to exit the settings page.

Yeah, tried that! Network only latch on to band 3.
Working or not ? Not sure !
Enabled for me in B3 + B7 (France).
Logo shows 4G+. I thought it was not working but it seems to be working. Sometimes I can see B3 and B7 even if there's no difference on download speed: strange !
View attachment 4394922Does it use more battery?
Works for me

Uper right 3 dots band locking
Done
Use network signal guru app to find two good bands in ur area and follow the guide.. i hav added band 3 and 40
if any other app show which band connted
With forced band (for CA) download speed is worst so I've reverted back to original values.
We can find lots a topics about CA problems on Xiaomi phones... and that's right, sadly.

Hi Folks,
When in Xiaomi launched Redmi Note 4(Mido) in India, at that time Jio was one supporting 4G all over India, hence to cut cost on Licensing Xiaomi approached to Cut LTE band Support in Mido. It launched with support of Band 3, 5 & 40, unfortunately with Time More carriers came with Band 1 & 8. Unfortunately Xiaomi didn't show interest in Unlocking Bands via Firmware update with Lol reason of Hardware Limitations.
But, I have Good News..
I am able to unlock those additional Bands using QXDM tool. It was simple and I tested myself in Different Circle with Carriers utilising Those bands.
When, I started working on Unlocking bands, I got to know in WCDMA, These Band 1 and 8 were enabled by default but LTE wasn't configured to use it. I researched further and came to conclusion, RF Module is same in case of WCDMA(3G) and LTE(4G), no it was just Firmware which wasn't configured to support it. So Basically, It had to support those bands and I went on with my idea and conclusion.
Things required are-
1. QPST Tool
2. QXDM Tool
3. LTE Band Calculator
4. Phone with Working USB Port
5. PC with Windows and all drivers up to date.
First step is to enable Diagnostic mode. If U are on MIUI it's easy to enable. just punch *#*#717717#*#* and You will be greeted with Diag Mode Enabled toast notification. And If are on Custom ROM, then U MUST BE ROOTED. Enable USB Debugging > Connect to PC > Now Open ADB Command Window(Hope U are familiar with this) > type adb devices (Device list will show) > adb shell > su (grant Root permission from phone) > setprop sys.usb.config diag,adb
However U can Use Terminal Emulator app too. Type su (grant root permission) > setprop sys.usb.config diag,adb
PS- Those ADB and Emulator commands may fail to enable Diag Port in Custom ROMs. If fails, then option is to flash MIUI and Use USSD code.
Now in device manager, U will see Qualcomm HS-USB Device with COM Port Number. If Windows is Updated and connected to Internet, Driver will get installed automatically.
Download and install QPST Tool, and QXDM Tool. Now Launch QXDM Tool.
1. Go to Options > Communication > There it will show COM Ports, Choose port and Now Change Target Port to your COM Port.
2. Click on View > New > Common > NV Browser
3. Now Click on Category Filter > Select LTE > Edit 06828 LTE BC Config & 06829 LTE BC Config DIV
4. Put phone in Airplane Mode before editing. BTW Note down default Values. To Read Values, just Click on 06828, in window
underneath select First one and Click on Read button and do same for 06829.
5. Open LTE calculator in Phone, choose Bands U want to enable. To Be specific choose Band 1, 3, 5, 8 & 40.
6. Edit first line of 06828 and 06829 respectively. To Edit, Just double click on Input and enter same Number that U see in LTE
Calculator app and now click on Write.
7. Wait for some time, now disconnect Cable and Reboot device and disable Airplane Mode.
Voila U have enabled Those Additional important Bands.
I have checked Airtel and BSNL 4G using Band 1 and 8 in AP and Jharkhand Bihar, WB, Kolkata and many more.
Attaching Screenshots for all.
Thank you it works...also you can add band 41 to the list used by some carriers.. Also LTE+(carrier aggregation) is also working ,tested in jio B3+B5 in my area.

Glad to know.
@hoshang.govil12 Do i take a backup of EFS to keep the unlocked bands safe? Or are they unlocked permanently. Flash addict here.
U can take QCN back-up and keep it safe. BTW Once u edit QCN aka With this method once it's unlocked then No matter U flash Fastboot ROM or firmware or Anything, It will remain unlocked.
You're wrong.Mido comes with This LTE band 1(2100), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 20(800), 38(2600), 40(2300).No need to unlock.

Indian variant of Redmi Note 4 only comes with 3(1800), 5(850) and 40(2300). Global variant has all those above mentioned bands out of the box.

It just show lte+ if your mido is indian. If you look on network signal guru. It still be using single Carrier. We can see clearly that ul_ca off tag in it. Indian mido's antenna don't support ca. If you have the global Variant you will have ca(lte +) and these extra bands as factory default

It kinda did work and also kinda worked. (Using BSNL 4G)
After following your process I used Network Signal Guru.apk to check if it was unlocked, and it shows those missing networks :laugh:
. But when I choose LTE in Mobile Networks the network won't show, it remains blank
. I thought it might be network issue. So I inserted the sim in my other phone Nokia 3.1 and it was showing 4G sign.
I m using bsnl 4g. I tried and I unlocked B1. I checked with Network_Signal_Guru.apk. But unfortunately it didn't worked. So I thought it might be network issue so i inserted my sim on nokia 3.1 and their it shows 4g. But on my phone when I turn on LTE on Mobile Network section on settings, the network remains blank. I have read many threads and community pages where all mido users says that it worked for them. But why is it not working for me?

Check in SIM 2 too. But Once Insert Jio SIM and reboot and then Insert BSNL in SIM 2. Or have U tried Factory Reset?
as a wifi user, does it benefit me by unlocking more bands?
What happen if you unlock all bands?
What if you unlock all 44 bands?

Cellular bands and Wifi bands are different so it won't benefit You.

See, there are hardware limitations over unlocking Bands and using it properly. On Software side, We can unlock every band but not all band will work as hardware won't be supporting.
