as the title implies , i'm using Rog3 tencent variant and i'm having mobile data problem. the download is slow , i'm getting 300-600Kbps while my Rog2 tencent variant is getting 3-5Mbps on same location , using same simcard.
I check my operators supported bands and this phone the tencent variant also supports that specific band , i'm getting full signal as well. it is not dropping , i check with an app and it seems like the phone is having a problem with band locking. it changes bands everytime resulting in mobile data disconnection , etc.
anyone face this issue? and is this a hardware problem?

i flashed my phone with the global rom and now when i lock the screen while using LTE Network i can't recieve phone calls
only text message arrives on locked screen
when the screen is not locked or when the phone plugged in charger every thing works fine
P.S. on 3g network i don't have this problem​
I bought new mi5 and faced similar problem and ordered a replacement.
But the same problem persists in the new handset.
So after going through a lot of search
I conculded:
The phone network does not support voice over LTE yet in some networks.
Currently it is supported in europe and japan and some networks of states.
So no need to panic xiaomi is getting a patch to update to fix this bug from their side.
Till time enjoy callin/ internet via 3g network
By pressing *#*#4636#*#*
Select network to wcdma by which u wont have any problem of incoming calls and no net issues!
If u dnt bother incoming calls ..u knw how to get 4g?
Well you're doing better than me my phones never displayed 4g in areas I used to have it with my lg g5 any ideas using the *#*#4636#*#* apparently lte is enabled I'm on Vodafone UK also allegedly supported
Vodaphone and o2 will not work on 4G with this phone as it only uses band 20/800Mhz which is not activated.
4G Network:
1800MHZ
1900MHZ
2100MHZ
2300MHZ
2600MHZ

Fixed in Xiaomi Mi 5 Global Developer ROM Version: 6.8.11 (MIUI8)

Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

Could it be you're own carrier hasn't got coveridge for LTE for your device?

In my country lte is Band 3(1800) and mi5 should support that band,right?

For me my carrier do support coverage for MI5, but just recently it went nuts
hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?
Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Sucks right? I wanted to switch carrier as well but then again, LTE coverage with smart sucks specially in my location... Hoping that this will be fix soon..
I used to have a perfect LTE with globe 4G+ after some time after updating OS version it went nuts

I updated my mi5 to miui 8 global and got 4g signal but only for a minute or less then it dissapeared and when i manually choose mobile networks i can only select Telenor 2g and 3g...really weird.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.
hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?
Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).
this is easy.
root then disable LTE band 41

Hey guys i have taken my brothers letv le2 phone. And iam facing airtel 4g signal issues. The speed of the net is very slow as compared to net speed when i put the same sim on my asus device. Also the 4g signal is very unstable. For sometime it connect to 4g then the data connection get lost for 4-5 second ( i think because of shifting to another frequency band i.e. gsm) . When i was using jio sim in letv le2 i was getting the same speed as compared to when i was using it on asus phone. I think reason may be as jio have only 4g bands thats why my le2 was not changing its band to gsm band, and net connection was stable. If anyone faced this problem then please give some suggestions. Should i switch to another rom? And currently i am using eui 5.9 21s. And also i have changed the bands to lte by *#*#4636#*#* and changing apn bearer to lte, but after some the band automatically shifts from lte to unknown.
Did you get any solution? I'm facing exactly same problem.
Hello,
I am now having issue with my K20 Pro. I'm using 12.0.5 xiaomi eu
Not certain but possibly started after I upgraded to MIUI 12.
Issue is that the mobile data never works when signal is 4G/LTE.
Internet only works if you find a stable 4G+/LTE+ signal. The system would tend to constantly switch between 4G and 4G+.
Another option is to use 3G/H+ Preferred option. H+ works fine but as we all know this is the older network which means slower but decent data
I have read some solutions to delete and reset your APN. But it never works either. Also compared the network behavior between other phone like Oneplus 5T and it doesn't have the issue even using the same network and same location.
I'm not sure if this has been raised to Xiaomi directly. But I'm hoping there's a fix for this.
Thank you!!

I dont know if its exactly the same issue I had , but I give you my solution , it might solve your problem as well :
1. download Activity Launcher from the playstore.
2. Open it and search "miuiBand"
3. Choose the network LTE band of your Operator(look it up in google) for example LTE B3 (if you use only 4G , look at LTE and not LTE Preffered)
4. Toggle Selection ON (Top).
Hope this solves your issue as it did mine.

I have this. However, I can't understand why it suddenly changes reverts from time to time. Do you always take a look at it whenever connecting to Mobile Data?
As I also check in Network Cell Info Lite, phone still connects to the band causing the problem (Band 21)

When you get low coverage or restart the phone or get out of plane mode , your network settings go back to default (band will be chosen automatically), but forcing the prefered network type ,you will prevent this from happening (you will only have to worry about restarts /phone / modem).
Making the choice permanent IS possible with root (Check this Link : https://forum.xda-developers.com/ge...ific-network-bands-snapdragon-t3744243/amp/).

Btw, I cannot get Network Signal Guru to work with Magisk v21.1 anymore
Mi 9T (not Pro), tried with EEA stock MIUI 12.0.3 and Xiaomi.eu stable 12.0.6.
Last time it worked for me on EEA 12.0.2 with Magisk v21.0
I tried now that Samsung Band Selection app., it complains that hidden activity is not found (on my Xiaomi.eu 12.0.6) and it cannot open band selection options
But I don't have a problem with bands, just curious to tesr the things?
Bought a Xiaomi Redmi note 9s last month for Christmas for myself.
It had MIUI 12.0.2 on it by default.
Played around with it for a whole month and everything was working perfectly...4g LTE included.
I don't have internet at home so I use my phone has a hotspot.
Average download speed was 60 megabits per second.
... Until I upgraded to 12.0.3, I then lost LTE and only connected using H+
So beware before upgrading because I have not found the solution yet other than flash with pixel experience ROM.
Edit :
Changing Network detection from automatic to manual fixed it !
My Redmi notes "global" phones 4 & 5 had to flash new ROM to unlock bands.
Hope this helps
I realised that this issue is most likely due to baseband limitation with our Network provider. Given that I'm using a China Variant, the basebands my phone is lacking needed basebands here in the Philippines. What I'm looking for now is a QPST guide for SD855 to activate at least base band 20. I can't find any that has enabled it thru QPST yet.
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.
