Does anyone know how to configure the way the phone lock to the different frequency towers? I.e. can we create a rule on how it works out which band it uses first.
i.e. In my area, i can get 2G, 3G and 850 WCDMA 3G. I want to configure my mobile to use the priority in order of
1. 2G
2. 850 WCDMA 3G
3. 3G
Anyone knows how to do this? Thx.
You can't control this as the towers tell the phone priorties. If everyone could choose whatever is "best" - say 2G - then the 2G channel would be jammed and then the 3G channel would be sitting idle.
The base station and the phone communicate and then mutually switch frequencies or channels.
You can manually lock the phone to 2G of-course then manually switch to 3G if/when you need speeds or something.
There are very valid reasons to be able to control how the signal is acquired. Some areas where 2G and 3G signals overlap, you may find that the 3G signal is weaker or problematic and you want the phone to hold on to 2G. It could be a particular band, i.e. 850MHz or 1800MHz.
Sometimes a particular 3G band is faulty so we need to exclude it.
Didn't say you didn't have valid reasons, hell i lock my phone to 850mhz when i'm using the stock ROM but on CyanogenMod can't do it. One reason why I did it is because 850mhz is stronger (obviously) but for some reason AT&T is camping everyone in the area on 1900. I'm guessing they are doing some LTE work on the 850mhz frequency so they push everyone off it to do the work needed but when I manually force it back to 850 calls work just as normal
Anyways, you can manually choose em using the network codes as I said, you just can't set up preferences as you so desire as that's controlled by the network, even if it's for reasons as mentioned. You can just disable 1900mhz and therefore only get 3G on 850 but if you go in an area where there's no 850 license then you wont have cell coverage.
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

I thought the Mipad 4 has only Lte and no 2 and 3G?
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.
Wondering if anyone else has network issues with their BC72 in Canada. I'm on the fido network which means no 5g.
The phone works absolutely fine on wifi, but throw in a sim card and the problems are as follows:
Phone randomly freezes with the screen off, needing a manual reboot.
Camera fails to start half the time
Calls drop, texts fail to send
Apps take ages to open or freeze during use
All of this is intermittent so it can work fine for hours then become basically unusable.
I know this is the Chinese version so I'm wondering if flashing the ROM would help? Thanks in advance

What bands does Fido use?? Also sounds like a faulty phone tbh...mind you I'm in the US with the same device

according to the fido forums
GSM ~ EDGE (2G) ~ on band 5 (850MHz).
UMTS or WCDMA ~ HSPA (3G) / HSPA+ (4G) ~ on band 5 (850 MHz).
To access LTE, the device must be compatible with one or more of the following:
700 MHz on Band 12;
850MHz on Band 5;
1900 MHz on Band 2, Band 25;
1700/2100 MHz on Band 4, Band 66;
2600 MHz on Band 7.
Fido doesn't offer 5G
I’ve been using this phone in Canada for years but I don’t have these issues. The CN firmware has different Google services including the phone and text app and also the camera app. Also it’s always trying to connect to servers in China but it’s extremely slo in Canada. You can flash a TW firmware and I’ll be good. Flashing stock firmware doesn’t require root or unlocking. Also I was with Fido before and the LTE bands seemed okay since I never experienced a signal issue.
