Hello everyone,
I bought 2 months ago a Mi Mix2 and I’m very happy with it
but since 2 days ago my 2 sim cards goes loop on 4G/lte option, either switches on and off without any connection (mobile data and WIFI).
Now the phone works good only in 3G data
I’m an expert user and I have tried many possibilities but without solution.
Installing other roms such as Global and China, stable and developer, formatting data several times, change SIM cards but nothing.
I also have read several forums without any good news.
someone has any good idea?
thx!

I've found that VoLTE conflicts (IMS maybe?) between SIM cards can cause this...have you tried ensuring that VoLTE is deactivated both in the settings menu and hidden testing menu?

Thanks, but Volte is disabled. I tried to enabe it but still Sim cards works only in 3G. I'm thinkink that Lte modem is broken...
Hi Stefano, I got the same problem. Did you solve it yes??

I have the same problem with xiaomi 5, but I found that whem my wifi conection is on causes problems with sim cards.
you can try this; switch off wifi. then restart your phone and you now should not have problems with sim cards signal, but when you turn again wifi the problems appear again, conflit with wifi,
I usually disable and enable the SIM Slot that have the looping issue. Not the mobile data, but the SIM SLOT.
Don't bother, it's a Mi Mix2 issue.
Phone has problems to switch between "receiving and making" calls and switching back to 4G/LTE.
And very often i can't make calls, cause the opponent can't hear me.
I do disable mobile data usage and/or enable airplane mode for half a minute.
It really is enerving. Thats a major issue.
Never will buy xiaomi again.?

I can confirm this issue... This is becoming somewhat of a deal breaker to me.
If anyone finds a working fix for it, do tell.

Same issue here.
Data constantly dropping. I'm not in a great signal area, but working fine on my Galaxy S8 for the past year.
To bring data back, I have to refresh it by enabling flight mode on/off. Constantly doing this.
Anyone know of a fix? I see someone above has flashed new roms, but no luck?
Do I just send back?
The issue seems very odd as I haven't encountered it even once today.
I'm getting curious just what might be causing it.
The only fix I found to work was by going to my cell provider. They provisioned my new Mi MIX 2 into their system (3rd phone - same sim card).

Hey!
I've had my Oneplus 3 for a couple of weeks now, and I am having major connection issues while using mobile data. Most of the time I am unable to get any connection so I can't even make a phone call. I have read about similar issues and how they have been resolved, but none of the tricks have done it for me. If I enable airplane mode and then disable it, I get a weak connection for a while (maybe 10 minutes). I have two IMEI-codes on my phone, like I should. WiFi connection works well. I am on OOS 3.2.4 at the moment.
Here's a list of all the things that I have tried:
Another SIM-card
Another service provider
Manual APN settings
Different OS versions
Turning radio off and on from the "secret menu" (*#*#4636#*#*). This has the same effect as the airplane mode, which means that I get a weak connection for a moment.
Every bit of help is greatly appreciated.
I had the same problem with 6 ROM (all based on CM). After a day or so i lost connection.
Now i'm on Official CM13 and its all working for 4 days (fingers crossed).
The only thing that i've done different is that i didn't use Titanium Backup and also CMThemer.
I don't know how helpful this is, but that's my experience with the matter.
Cheers !
I am having same issue from the day 1 of my usage. Upgraded OxygenOS, tried different SIMs, changed APN, toggled preferred connection LTE to 3G etc and even on Official Cm13, the issue persists. Even when I am outdoors, the connection is poor and unstable. The same SIM works very well on Oneplus 1 without any issues. I am really fed up and regretting my choice to buy Oneplus 3. Is there any way to solve this issue? I stay in Dubai and there are no Oneplus service centers here and neither I can return the device, as the return period has expired.
Hi all
I've searched the web to fix this SBD I can't find a solution because I'm stuck with Edge download speeds and fluctuating connectivity.
Running LineageOS 20170117.
A2001 OnePlus2 phone.
I've tried selecting different connection types inc LTE only, WCMDA, etc and nothing.
I've changed my APN settings to default too.
Any input? Using Vodacom in SA (essentially Vodafone UK owned and network).
Thank you
Regards

I'm facing exactly the same problem. I've got two SIM cards from the same provider with even the same subscription. Happens mostly when I disconnect my WiF, I have to restart my fevice to return to LTE connectivity.

I've reinstalled OOS 3.5.8 and it's fine.
I've found that my battery life is terrible now though so I want to go back to Lineage.
Lineage is the best at everything, except speed but I think it'll be fixed by now.

hi there,
i am new with OnePlus, and am i really so happy from that decision.
just i need one strange question. While on phone call i cant use internet connection on my both service provider ( different gsm companies btw ). even my old M7 was able to done that. have i done something wrong on settings? or this is like that?
thnx
regards
I can't use internet while on call me neither
No issues here. But I'm using a single sim for both data and call.
Iam on OOS 8.1 beta 4 using 2 sims, same can't use 4g when on call but only sometimes I have noticed my 4g drops down to 3g while on call, there should be a solution to this, I am gonna try some 4g booster apps from play store lets see if they help, cheers everyone.
Don't think this is an issue. I don't recall I could do this ever on any phone. But if you are connected on wifi there is no trouble at all. Guessing you can't do both ?

there's an option in "developers options" "mobile data always active" , if u read the little detail underneath it it says mobile data will be on even if the WiFi is connected I presume this way both will be on, but I still don't know if mobile data disconnects at the time of making a call, but I will experiment and see what happens, cheers.
I had the same issue on my OnePlus3 a while ago. I haven't encountered it on the 5T though. I'll try to look for a solution when I get home. In school atm.
I'm using turkey Vodafone and when I'm on call i can use internet but it drops to 3g from 4g, unless you use volte its normal when it drops to 3g.
Yep definitely an issue. I'm Virgin Media and EE
Don't remember it being the case on the OP3 but could be wrong
On op3 I remember having the same issue. And note 3 and note 1 too. That's why I don't think it's an issue per say. Maybe a wrong implementation or something. Can maybe be fixed by a piece of code (magisk or xposed)?
Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks
dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too
AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.
Issue for me here too, but I'm in Australia on Telstra network.

Hello, I tried searching on XDA and elsewhere but could not find an answer so I hoping to receive help by writing my issue here.
I have bought two POCO F3's 128GB & 256GB on Amazon & Aliexpress respectively.
They both have the same issue when using mobile data (4g) loading websites and doing voice & | video calls like FB messenger there are interruptions like for a second there is no sound or video freezes. It does not happen on wifi or other phones.
I tried resetting APN, selecting proffered network to LTE, rebooting, switching SIM slot, resetting wifi, mobile and bluetooth settings. Updated both phones to MIUI Global 12.5.1 still no luck.
Country Lithuania (EU) carrier TELE2
We really like the phones, but this is pretty annoying as we do a lot of video calls due to quarantine and what not.
Amazon suggested to replace the phone but seeing as two of them having the same issue it will most likely will not help.
Anyone experienced these issues and came up with solution?
From what u described, seems to me is a bandwidth/mobile data speed problem. Looks like is not enough bandwidth for video call to work properly. So, what is ur bandwidth provided by ISP? What mobile data plan had from ur telephony provider? Maybe ur mobile data signal is low in the place where u make the call from. It can be so many reasons for the issue u confront with, other than a problem with phone itself (a hardware/software issue).
you can also try the latest china stable firmware 12.5.4

Hi, ty for reply. That should not be an issue, reception is great and we tried it in multiple locations. Our previous devices Iphone 6s/ Poco F1 worked flawlesly with the same carier.
Here is speed test done on mobile data.
Any other ideas?
Found this thread here and I found a solution. Apparently there's an issue with network interruptions in general, especially on phone calls. This can be avoided by switching on VoLTE and WiFi-Calling. This is what I found out over time.
Here's the fun part though: Through a little bit of research this turned out to be a vodafone-problem. I am just guessing you guys will be either also on vodafone or on the corresponding bandwidth in your country.
It seems to be a bug in the F3, but also something that happens when VoLTE is not activated for your SIM card. The phone will try to use VoLTE and this connection will fail, forcing the connection to reset. It will be back in 10-20 seconds, but this is of course super annoying whenever a stable connection is needed (like phone calls...)
Enter *#*#86583#*#* (86583 = VOLTE on dialpad) on your phone. and it will give you a feedback that the carrier check has been disabled. Note that this doesn't mean that VoLTE has been disabled. Checking the network for the capability is disabled then, which makes the setting visible on the SIM card settings. Same works for VoWifi btw.
Try playing around with those settings and see if the connection drops persist. I have no logical explanation why this is happening because what I am telling you is obviously call-related - and I do realize that what you're describing is about the data connection. For me this was related however and solved my issue.
Possible solutions:
a) try to get your service provider to switch on VoLTE for you (this worked for me). You're going to need to call support for that. They will reset your SIM card in the process. Reboot your phone and be done with it.
b) If a) is not possible, deactivate VoLTE in the menu that you activated with the code above. If you're lucky, this will stop the phone from trying to get this type of connection working, even though it's not available. This is broken exception-handling on the phone's side and Xiaomi promised to fix it. They are aware of the bug (since Aug 20th btw) and promised to push a fix into the next MIUI release
c) play with the settings and try to get the phone to not use alternative protocols, just 3G and 4G, also deactivate Wifi-Calling.
Hope this information will help somebody. If all goes well, Xiaomi will fix it and this will behavior will be gone in the next release.
same issue for me with 12.5.7
data interruptions all the time and full signal loss
very disappointed with this device from the day i got it.
O thought I'm the only one facing this problem.
It's so annoying to get an interrupted connection in the middle of the game.
not only game, and calls, i have too much trouble to get throught a call.
Hello all,
i was also affected by a similar issue.
In my case the symptoms were:
On mobile data/5G some apps would be accessing the internet but others wont..
I was able to overcome this by resetting the access point settings and then applying the ones found here:
Cytamobile-Vodafone Cyprus APN Settings for Xiaomi Poco F3 GT - APN Settings
apn.how
I hope it helps...
My fix for this occasional issue is to set the phone to '3g' only in network settings, then flick it back to '5g'. It seems to be area specific for me. Very bizarre.

I have the same problem, it helps to have the settings volte and vowifi enabled. Sometimes it looks low cell signal and loosing the connection.
Has anyone return for service the device?
It looks like we still have this problem, my F3 modem is crashing every few hours especially when it switches bands, very annoying.

It really is! We need a bug bounty for this
Hey I ran into the same problem in Hungary Vodafone Poco F3, 14.07 MIUI
4g net is working flawlessly but
Network connection is lost when start dialing
Nobody can reach me on phone
Enter *#*#86583#*#* (86583 = VOLTE on dialpad)
VoLTE select option turn on/off
Enter *#*#869434#*#*
VoWiFi select option turn on/off
I tried to switch on/off both but no solution just yet
sby has answer for this?
Where should I post this problem to be solved?
I also have this problem and I am from Iran. My mobile ROM is the global version. It seems that this problem is caused by the Poco F3 mobile hardware itself. If anyone finds a solution, please let me know, thanks.
