Hii guys,
I recently bought a jio sim for my Redmi 1s. As we know the sim is for only 4g devices but there are certain hacks. I tried one of them.
It suggests that going in engineering mode ( after dialing *#*#4636#*#*) then changing network type to LTE/GSM auto and then search for network.
But when I change network type, after exiting the engg mode it automatically changes to WCDMA preferred network.
Can anyone help me!!! Plzzz!!!
Btw I'm new in this forum.

That's all fake over Internet. It'll not support any 3g phone with any of the methods given over internet.
Because it is a 4g sim and also jio has 4g tower. If it have 3g tower then only it support in 3g device.
Thank you sir for your guidance.
I have an issue with every build I've tried of MIUI 8 (Stable versions), but not with the developer versions of MIUI 9.
The phone will not connect to UMTS/3G networks with either sim. LTE works fine, and there's no GSM where I live so I can't test that.
It will connect for a moment when first booting up the phone, then immediately disconnect and stay disconnected. It can't find 3G networks when searching either.
Again, this doesn't happen on MIUI 9 builds, but I figure this big of a bug, they would never release it as stable. Can anyone else let me know if they've had this problem?
Hello, I`m having same issue, here in this way. In town there are many repeaters. Here is no problem, in germany many 4G-Networks are working in band 20 (800 mhz). In areas, where no 4G/lte is possible, the mi mix2 (china stable miui8 and china dev miui9) the mix2 can not connect to 3G/UMTS. A smartphone Redmi note 4 with this SIMCard connects to 3G/UMTS and gets connection data to HSDPA+. The mi mix icon diasappears and there is a "emergency" Icon. Then the mi mix2 connect only to GSM and after 1-2 minutes get Data to EDGE. But at this place it is possible to connect to 3G. I rebooted the device many times, changes sim to other slot. Tried China dev and stable. Last test with XIAOMI.EU and EPICROM for MIX2 are sad. Same issue
Many MIX2-User have this effect. I have this effect on Sim-Cards from provider Telefonica/O2. I have tried 3 Sim-cards from provider O2. No 3G - Connect.
In germanys-forums the is a hint to define "force 3G-Connects". Some user writes, that they do not have this effect with this definition.
Does have XIAOMI a 3G-Bug with new MIMIX2??

If you're on MIUI 9 beta, you already have the radio I'm talking about.

The default Setting for this SIM is: LTE/TD-SCDMA/WCDMA... this is almost wrong, because we havent TD-SCDMA in Germany, i ve switched to LTE/UMTS RPL ...this seems to work better with my o2 card.
Sometimes the connection breaks down from LTE or LTE+ to H+ ...but after the break down, i have no data connection. If i activate flight mode and re enable data, i also get H+ but for now with data connecting. This is very frustrating
Also that my Settings to LTE/UMTS are removed after a reboot or i switch to the second sim. Any suggestions to fix it permanent to LTE/UMTS ?
Did anyone tried MI MIX 2 Global - Version?´ Bug exists still there?
I am on 9.1
I set it on LTE/TD-SCDMA/GSM. I live in Germany too and have a O2 card.
GSM is slower than UMTS cause it's older. But it works without problems.
Now I trying with LTE/TD-SCDMA/UMTS. I have to say that I have some problems too.

we dont have TD-SCDMA in Germany so, this setting is false... TD-SCDMA is a chinese or asian network standard

yep, this seems to works best and also breaks down to gsm if there is no other network available... but...
sim 1 + data card : o2
sim 2 as voice card: D1
if i make a call with sim 1 / D1 my first sim as data sim loose the data connection, even it is connected to a lte network...strange thing today i had a conf call over sim2 for about 4 hours, while this time i didnt recieve any mail or whatsapp.
but if i set sim 2 / D1 as data card and make a voice call, this card wont loose data....strange, maybe a o2 issue?
edit: made a test with D1 as data and if make a call with the o2 card, also d1 loose data instant
I have a new (2.nd) MI MIX 2. And: I have the same Problem. O2 is switching vom GSM/EDGE to UMTS an gets no Connect. Then only "EMRGENCY CALLs". And then GSM again. o2 is provider. roaming is on.
With second SIM (Vodafone) there is no problem. Is there a fix for that problem? One member wrote there is a new "radio". Where to find it?
Same SIM (o2) in a REDMI NOTE 4 (LTE Band 20 800 MHZ) is "ok". It is an MI MIX 2 - Problem!
I have the MIUI 9 Global.
MI MIX2 with O2 and no LTE and no 3G/UMTS??? Joke?

change network to LTE/UMTS PRL ...then it should work better PRL = prefered roaming list; go to settings -> about phone -> tap several times on the info about internal storage -> the network app will appear, now you can change network settings... until next boot, then you have to set it again
maybe mix 2 has a problem with national roaming?! cause o2 uses national roaming -> their own network and the network from e-plus
Yes, the MIX 2 does have issues with switching to anything other than LTE. Even when it says it switched to H or H+ there is actually no reception at all and it takes a few minutes for it to recover. Really annoying, hopefully the engineers fix this issue as soon as possible. Pretty inexcusable bug for such a device.
Hello, Switching to " LTE/UMTS PRL" has the effect, only UMTS/3G-Connections are possible. No LTE/4G. Provider: German O2.
XIAOMI might have to fix this bug.
Q: Has anyone took a Message to [email protected] ?? http://en.miui.com/forum.php?mod=bugfeedback&fid=5&page=1

LTE/UMTS PRL fixed that for me totaly ... i dont had any issues since them! I am also getting LTE and LTE-A with o2 and i am travelling a lot due to my job in germany.
i think its also problem with o2 and national roaming. if you search for this problem in google, you will find the same issue reports from other devices within in the o2 network. I did never had the same problems with my other D1 card in the same device.
LTE/UMTS does not work for me.
Since yesterday I use LTE/TD-SCDMA/UMTS and it works fine.
Provider: O2 Germany
It looks like 3G/HSPA doesn't work when roaming (possibly local roaming too). LTE works fine. In the UK I can get internet all the time regardless of connection type. I travelled abroad and only LTE worked using my UK SIM. This also happens on AOSP based ROMs since I'm using Resurrection Remix and still experienced the issue.

Yes, this is clearly a firmware-level issue. They need to fix their modem.
Hi, i have a problem with my mi6 and network provider T mobile from Croatia. When i hit call button on 3g network i have a drop of signal and cant make a call or recive one. On 2g network everthing works fine. I tried with other network providers and mi6 works like a charm. Something is beetwin mi6 and t mobile provider. I tried to change sim, try all roms (china, global, eu rom) and allways the same.
Today i tried to put sim card in new mi mix 2 and phone is working with my sim and can make a call on 3g.
Do you have any solution?
Can i install mi mix2 rom on mi 6, or modem driver?
.... Thanks for answer....
Same issue.
Calls only works ok when in 2g Mode (on 3g always the call drops).
Any solution?
me too. i used the mi5 and mi6 and same problem. i use 2 sim cards. when the first sim is in 2g or 4g never had problems. when i put sim card in 3g, i have problems about once a day with missed calls , no network (ccant make phone calls or receive calls).
i changed the sim card changed roms, and still nothing. its drivingg me crazy. i like xiaomi but these are serious problems.
im in global version miui 9. I live in europe. it happened wiith miui 8 also in xiaomi mi5.
Anyone have suggestions how to resolve this please?
still having this problem. any advice?
still unsolved
problem solved selecting gsm only in second sim with this command *#*#4636#*#*
Please leave "Thanks" if this thread helped you.
_____________METHOD : 1________________
1. Open dialer and type : *#*#4636#*#*
2. Choose SIM1 or SIM2 to enter reception menu.
3. From dropdown menu ( LTE/UMTS auto (prl) as default ) change it to : GSM only
4. Wait until your cellular will reset and turn back on.
5. Less dBm amount = better signal strenght.
6. Test best signal for your network and share it in comments.
________________________________________
_____________METHOD : 2________________
1. Open SIM tray
2. Change your SIM car slot to Slot 2
3. Check if your signal strenght increased and share it in comments.

I'm waiting for my RN8Pro. Is there signal strength issue by default?
You can change this in network settings menu the normal people way and also allowing only GSM will relegate you to 2g network that has indeed better signal but will kill your internet speeds.

A little bit I think. At my house, with Redmi note 7 I have 4G+ ,with Redmi note 8 pro I don't have 4G+ so often and on places that I have it with Redmi note 7
How to increase the sharpness of incoming call voice? Most of the time, voice is muffled.
The incoming voice leaks from the back of the front speaker too
how to increase the volume of the headphone and speaker?

I try this.. when I change LTE/UMTS auto to GSM only I loose 4G and have only H+ that is slower than 4G.. and the signal is the same.. I try it on one spot for half an hour
2G has almost everywhere coverage and it's too old technology to use.
When UE is registered to 2G network it can't handle voice+data transmission simultanously (most networks does not support DTM technology).
Also 2G is not designed to used AMR-WB voice codec, only simple AMR which sounds like **** to be honest.
So this tutorial is pointless, sacrifice better data speed for rubbish voice and ultra slow data speed

Redmi NOte 8 Pro has big problems with LTE 4G + tape management. The phone does not keep the 4G + it switches and stays in 4G all the time. It's a modem management problem that does not support the double-banding needed for 4G +.

Xiaomi Redmi Note 8 Pro model M1906G7I (Global) doesn't connect to 4G LTE
Hi there! My problem is even worse than this you are sharing with us. I bought a Xiaomi Redmi Note 8 Pro model M1906G7I (Global). However, there is a lie about it, the specifications indicate that about networks it works for the following 4G LTE bands: B1/B2/B3/B4/B5/B7/B8/B20/B28, but it is not true as it only works for B1/B3/B5/B8/B40/B41 (I found it out by entering to engineer mode *#*#3646633#*#*). Therefore, in my case I can only connect to 3G because my service carrier uses B4 (1700 mhz, 2100 mhz) for 4G LTE. Besides that, everything is fine with the phone. What I am trying to find out is whether it is possible to activate or unlock the B4 band so that it can connect to 4G LTE. If anybody knows about a solution to this issue, I would appreciate the assistance to this matter.
Hi,
You don't have the global version M1906G7G
Global : B1/B2/B3/B4/B5/B7/B8/B20/B28/B38/B40
China : B1/B3/B5/B8/B34/B38/B39/B40/B41
India : B1/B3/B5/B8/B40/B41
You must get a refund if you bought the global version, and change to the M1906G7G to be able to use B4 .
I just tried this on my note 8t. Switched to GSM only and immediately even before restarting the phone, went from 1 bar to full bars. Speed tests show much more bandwidth available (now at 11.8mbps/3.1mbps). Sweet. First post I found after a search and first solution just flat out worked. Still think I should be getting higher speeds (I don't think I have ever really cared about the mobile speed because I am almost always on wifi, and do not recall ever doing a speed test, but at least it's better than it was now.
Hi everyone. I have installed this ROM (16.0-20210215) on Zenfone 3 and I would like to know if any of you have had problems with the data network. In particular, when the network switches to E (EDGE), the screen lock is activated forcing me to insert the pin until I deactivate the network or until the data network switches to LTE Thanks.
