Hello,
I am using Redmi Note 3 SD version. I have used it since December 2016 with Jio(India)
It worked perfectly. Now after using it with Vodafone 4G , i faced issue with 4G and most of the time got 3G network which i thought was restricted to that carrier.
Now i switched back to Jio and 4G drops constantly in some areas where other phones work perfectly with same SIM
I unlocked Bootloader flashed old MIUI version and rooted my phone
I installed Network Guru in that
for Band 40(2300) it drops constantly with LTE RACH being Radio Link Failure and Failure at MSG2
When i lock it to BAND 5(850) it works perfectly. Can someone help me find out whats the issue? I would love to get back to using all the bands as this may prevent me from using network in some areas

My kenzo has the same issue with China Mobile(China).
Failure at msg2 for band 38, band 40 and band 41.
Currently, I lock it down to band 39 to get it work.
I tried another SIM card by China Unicom doesn't have this problem, it uses band 3 and works fine.
Tried to flash the original ROM and modify the NV with QTSP but didn't work.

I think its an hardware issue, replacing the motherboard might be the only way
My MI PAD 4 LTE has this strange behavior:
- When WIFI is on and connected the tablet shows 4g connection indicators
- When WIFI is off I have "no signal" on the 4g connection
Some additional info:
1 - I'm on latest China Stable ROM (MIUI 9.9.26.0)
2 - I've tested the simcard in another android phone and 4g works flawlessly
3 - I've checked for IMEI blocking here in Brazil and my MI Pad 4's IMEI is or blocked
Any ideas or suggestions?
Hello fsworm,
I have a MI PAD 4 with LTE, too. There was a fake-Rom GLOBAL 9.6.7.0.0 installed (BANGOOD) to my PAD4.
Same effect as yours. SIM-Cards German O2 and German VODAFONE
Login to networks is not possible.
Same effect witch XIAOMI.EU - ROM 18.10.8 and MIUI stable China 9.6.27.0
Any Idea? Have you reached something?
Same problem, MIpad 4 LTE cannot access mobile network
I have the same problem. MI pad 4 LTE from China in use in the UK, it does not seem to register with the network provider, hence no access to mobile data.
The device comes from China and I have not unlocked it or changed the Rom.
Any idea?
Thanks!
Same here.
I AM in Portugal and i cant connect LTE without WiFi.
This is China ROM.
Stable version .
Any help?
mipad frequenties
I've the same problems. It seems that not all bands are covered like they should. When I go to another location I have connection, but it should also connect on my home adress.
The tablet came with the fake global rom and unlocked which I even didn't started. I've flashed first official chinese rom with fastboot - installed twrp - format data - installed eu rom MIUI 10.2 8.10.25. Everything works except the network. That's really the only thing I find really negativ on this tablet.
The used frequenties for mipad 4 plus should be :
4G LTE-64GB+128GB B1 (2100), B3 (1800), B5 (850), B7 (2600), B8 (900), B38 (TDD 2600), B39 (TDD 1900), B40 (TDD 2300), B41 (TDD 2500)
There is really something wrong with the software of this pad.
-deleted the other frequenties as they are wrong - information provided to me was wrong

So, with the EU ROM you also have problems with LTE network?
wtf, i think i will sell my Mi Pad
I am in Austria with China Stable Rom 9.6 and for me works Lte without enabled Wifi,no Problems with it
I have such a strange behavior last year with my Mi6 in Croatia.. As soon as I crossed the border to Croatia, I lost any signal.. Only with Wifi it showed connected.. But when we were at Zadar (~4hours) it suddenly had LTE connection.. I dont know why it didnt work before, but since that I have no problem

Nobody shows 2 or 3G.

Related to mi pad 4 plus network not working
Its simple...since this mi pad 4 plus is LTE version... first u have to subscribe 4g in the sim card using ur phone (cellular device) . After that u can insert it in ur mi pad 4 plus...and it works.

So -just to be clear about what you say here- installing the Global Rom does not solve the issue of stability of mobile data? Have you also unlocked the device?
Because in that case I would spare myself the trouble of getting the Global Rom if it does not solve the issue...
Thanks

Correct - I was misinformed by a website that said that mipad 4 had these frequenties which was not correct. It is however really negative that there is no band 20.
Same problem, i have only signal with Wifi on (but can't use 4G), i use last xiaomi.eu rom
With wifi off, 4G is off
Someone can feedback xiaomi.eu team ?
Probably need upgrade for network driver
P.S : French network Bouygue Telecom, if i use huawei 4G router, the simcard work
@Asgardcfr 4g is off and you wonder why 4g is not working??? Really?
No you don't understand, when i switch off Wifi, i have no service in 4G but 4G is, of course, is ON.
It's probably a bug ...
After having plus model for almost two months and using it all over the country my conclusion is that LTE data does work when wifi is switched off. But.....
This tablet support only B3 band (1800MHz) and range and coverage of that band is usually worst than B20 band (800MHz). Everywhere. Add to that not exactly great reception of the tablet and the result is that with wifi on, tablet always shows network signal even if it actually isn't connected to a network. With wifi off, that is not happening and data does not work since it can't use B20 or 3G or anything else. But moving with it in area with 1800MHz coverage I do get signal and 4G label and data works again.
This was driving me crazy also, and I couldn't find an explanation why does it sometimes work and sometimes doesn't but after 1693758935 checks with Network Signal Info on different locations......
With wifi on but no B3 signal
a lot of bars but it's not even connected to the network
With wifi off but no B3 signal
zero bars, as it should be in the first case also. since it's not on the network
and outside of the house, wifi off but in range of B3 signal
......and connected to bonbon network

This is plausible, and makes sense, but the question is can it be fixed easily? Is it possible to modify the band?
Just to add: got my tab yesterday and put my Vodafone data sim in it - 4g/LTE worked perfectly well to download my apps etc, I got home and added Wi-Fi which was flawless.
Today I left my house with my tab in my bag and realised data is no longer working, after reading this thread it seems connecting to Wi-Fi has been a big factor.
Only adding this info as my data was working perfectly well before I'd connected to Wi-Fi initially.
I'd love a solution! Thanks
Ok as a pretty persistent person I may have found a solution - I am posting this response on LTE but this may be a premature shout!
I cleared all network settings using the usual menu, restarted the tab, connected to WiFi, turned wifi off then went to 'mobile networks', deselected the automatic network selection then manually scanned for and connected to Vodafone LTE. (Edit: wifi may have been on when scanning available mobile networks)
This seems to work. Since; I have reconnected/disconnected WiFi and restarted my Tab... LTE still working.
Hope this is a permanent solution for someone, so far so good here.
IMO, the only bug here is that with wifi on it shows network signal that it can't use while that does not happen with wifi off. But other than that, 1800 LTE works regardless of wifi status.
Hi all, sorry if its not relevant to post here but i need help. I am using poco m4 pro 4G (g96) version which is 4G+ supported phone but it doesn't show 4g+ when mobile data turned on. While my 3 years old redmi note 8 pro showing 4g+ in exact same place exact same network sim card etc. I have tried messing with Apns and engineering mode settings but everything seems fine. Any idea what's going on?

Probably because
1. Both phones support different 4g+ bands, and your carrier might not support the bands which is compatible with the Poco M4 Pro.
2. Xiaomi probably forgot your carrier exists and maybe the phone's firmware lacks the necessary configurations required to support 4g+ with your carrier.
Hi. Happens the same to me.
Moto g52 uses 4g+ meanwhile poco m4 pro 4g doesn't. Same operator(ho mobile, Italian virtual of Vodafone) , some place. Nothing we can do but changing phone. By the way even without 4g+ it works fine so we have to live with that since there is no way to enable it.
