Question Poco F3 possible mobile data restriction - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

Poco F3 (Alioth)
Global
MIUI 13.0.6
MIUI-V13.0.6.0.SKHMIXM
Since a few days ago, my phone has been turning off the mobile data for both SIM Cards. At first i suspected my main SIM was damaged so i went to my mobile provider and got a new one. Still the same.
I have 2 SIM cards with different providers. SIM1 got LTE Advanced service recently and now it can reach 100Mbps. SIM2 has LTE service and usually tops at 6Mbps. The issue only happens when the SIM1 is Active as the Data SIM. When i switch my Mobile Data to SIM2, the problem does not happen. Even with a new SIM card for SIM1 provider, no solution.
The problem started at the same time the LTE Active feature was activated in my city. When there's no LTE+/4G+, only LTE/4G, the issue does not happen.
I think there's a bandwidth restriction on my F3, maybe on some app mobile data permission, but i can't find it. Should i do a Factory Reset?
Thanks in advance

Security -> data usage -> settings -> Data plan -> When data plan is used up
select "show warning" instead of "warn and turn off mobile data"

Hello. Yes, i did just that but the issue continues. It's not a complete shut down of mobile data. It's more like a reset, because the data gets disabled on both SIMs for maybe 10 to 15 seconds and then turn itself on. During this 10 to 15 seconds, the Mobile Data widget is totally unusable even when pressed.
I've just check and it happens only when the 4G gets the +.

only thing i can imagine is
faulty sim
or
faulty phone hardware
or
bad kernel
or
bad rom
or
the simplest of them all... the reception, where you are at, is bad

Thanks for your reply. I got a new sim card yesterday at my office before posting here. And did several Speedtest and GNetrack test on site. I work in a Mobile Service Provider and in my office the signal is perfect because the eNodeB are everywhere.
After the sim change and the signal/bandwidth tests, i too suspected the rom, the kernel...or the hardware, so today i started with the simplest: data back up, then redownloaded the latest MIUI update, installed it and did a factory reset. So far, the issue only ocurred one time, barely after the factory reset. After updating all the apps and related (Google and Xiaomi), the phone is using the LTE Advanced connection without repeating the problem. I suspect it was a bad rom, or some app with a mobile data restriction that got reseted to work again. Still, i'm cautious and keeping the phone under observation.

most clean way to make sure it isn't a rom issue would be to clean flash with fastboot rom

T-mobile Orange share on a root?

Hi all,
I'm running neo's latest 7.9 fully rooted etc. I've tried to take advantage of the fact that in the uk you're supposed to be able to use both tmobile and orange networks. Despite doing everything you're supposed to including running all steps via CS my sim card wont register on tmobile.
My question is, is this anything to do with de-branding or rooting?
Any help appreciated
Sent from my HTC Desire using XDA App
I don't see how it would. I'm rooted and debranded yet mine works. It just takes a while for it to work. When did you register it? And I don't think this is really 'development' by the way.
I was originally on T-Mobile, followed the steps and had all of the text messages (took around 24hrs for all of them to come through).
I had noticed that I was still getting around the same signal, which was weird as I practically sit next to an Orange transmitter.
Then I noticed I had to change my provider in the phone's settings from 't-mobile' to 't-mobile orange' and *wham* full strength.
Sorry - can't say from Orange to Orange/T-mobile.

I dont have that on my settings.
I have the usual single operator list. Maybe it will take 24 hours but I got the texts to confirm its been set up almost instantly.

I did this a few weeks ago and I didn't think it had made any difference whatsoever. Signal keeps dropping out for no reason, 3g is rubbish. Then just a few days ago I had a text come through "congratulating" me on connecting to T-Mobile for the first time, so I guess it is working.
I don't have any T-Mobile Orange option to choose though? Also, the Orange signal still seems to be cutting out. I'm considering ringing them up and telling them that they're in breach of contract and I'm terminating it because they can't provide the service they agreed to give me. Might shake them up a bit.
Have you tried turning on your data roaming in mobile network settings? It said something about it when I did it earlier on today and mine started working a minute after I'd text YES.
works fine for me. i'm running leedroid 2.2a and works perfectly. I now get full signal in my cellar where my signal used to cut out and my phone displays T-mobile (orange) T-mobile in the notification bar. the signal kicks in depended on the strength of the other carriers signal.
phono
EVERYTHING EVERYWHERE that what theyre calling it ... more like Some more in some places to be honest but...
download PHONO from android market..
it shows a great logo for each connected network and you roaming status.
and then providing you did the activation setup orange asked you to do - and you select roaming - it all works perfecly...

You guys know you're not supposed to "Choose" anything?
Infact, the only setting you should change is to allow Data while roaming (Roaming should already be enabled).
If you're on T-Mobile, it wont switch to Orange if the Orange signal is stronger than the T-Mobile one and vice-versa, this isn't coming until early 2011.
What it will do however is, if you drop your signal completely on 1 network and there is signal on the other network, you will roam on the other network until the phone can regain connectivity on the home network.
Moved to Q&A as not development.

AT&T hotspot - "Wi-Fi Hotspot Access Failed"?

Ever since AT&T revealed that all unlimited users are now capped to 3gb/month (5gb for LTE), aka no more 5% crap, I can't get my Nitro automatically connect to any ATT hotspots around the town. I get message in notification bar saying
Unable to confirm eligibility, please call Customer CARE at 800-331-0500.

Before that, every time there is a hotspot available the phone automatically connects and nothing required from the user's side. Now I have to manually open browser and agree with their terms of service.
Anyone experiencing this?
I will test mine out to see if I get the same issue, and report back my findings.
I've had that happen a few times recently too. The app would seem to keep trying and would eventually connect successfully.

I'm having the same problem. I've been bounced back and forth between AT&T Mobility and AT&T Wi-Fi so many times. Like you I can always get in by going to the login screen and logging in with my DSL credentials. I also have a grandfathered "unlimited" data plan.
I recall this happening previously (like when I go through a McDonald's drive-thru) but I've only chased after it since March 1. It's happened in 2 different hotspots, one in Boston and one in Memphis.
I'm on a Samsung Captivate with OEM Gingerbread.

Here is my conspiracy theory:
AT&T trying make us, unlimited plan users, use all the capped data as quicker as possible to slow it done sooner, make us more pissed off and switch to limited plans.
Make sense?
Try restoring the hotspot app in Titanium Backup again and then reboot.

Can't use Titanium. I'm not rooted.
I tried clearing the application data. I'll post back whether that helps or not.
Running latest Kernelpanic rom I don't experience this problem.
I finally got my WISPr connect to work. In "Wi-Fi settings" I had "Network notification" unchecked. I checked this and then went to an AT&T Wi-Fi hotspot.
It connected!
Not wanting to leave "Network notification" checked and get all those nagging notifications I unchecked it and visited another AT&T Wi-Fi hotspot.
It connected!
See if this helps you.
It is actually nothing to do with our phones, it's ATT ****ing with us.
I've checked it with 3 different phones, all had the same problem.
Now, all three one day connecting fine another - no go.
Come to Canada it works...wait forget it we don't have ICS. ;-)

I fully believe this is exactly what they are doing. It pisses me off, but instead of switching plans I'll switch APNs. HAHA I win!

Disabling VoLTE (Verizon)

Hello all!
Is there a way to turn off VoLTE? I use my phone as a hotspot, so when I get a call, I don't have internet access. I'm assuming this is because of VoLTE since my last phone (Droid 4) didn't have this issue.
Thanks!

Is this the option you are looking for? 'Enhanced 4G LTE Mode'

I always thought having that option disabled is what caused data to turn off during phone calls. I have it enabled and I can still use data while on the phone. That's the toggle to the off VoLTE though.

Sounds like you aren't using VoLTE in the first place. Turning it off won't give you data during a call it would do the opposite.

I've tested it with that both on and off and still lose LTE during a call. :/

Talk and web is only available if you have advanced calling option turned on within your verizon account. Its free.
It doesn't sound like you're using VoLTE exactly because you stated you can't use simultaneous voice and data. Here's the deal: To save battery power or whatever, the additional radio added to Verizon and Sprint (CDMA) phones to enable 4G has been removed from a lot of them, rather converged.
Verizon has always had this problem and they got around it by, finally, adding an additional radio to handle the 4G to many phones. On CDMA networks it's either (I think analog) voice or (I think digital) data. Then, I guess expecting this great big transition to VoLTE (and only needing one radio to simultaneously handle LTE and Voice over LTE) "they" reverted phones to the original model. I mean that has to be it... I would gladly charge my phone more to be able to be able to hotspot and talk! Or maybe they want to sell more JetPacks and separate line access fees!
(This is what allows for all that red on their coverage maps as Verizon's original voice frequencies do rock for signal strength and reliability. The data maps look a lot more similar amongst the carrriers: concentrated on major "markets" as the efficiencies of cities drive the capital to create the networks--rural areas have lousy 4G coverage).
The GSM networks from T-mobile and AT&T automatically fall back to 2, 2.5, 3 and 4G frequencies and can use the newer and the older networks at the same time. You also get better conference calling (up to 5 people) and call management on the GSM based networks.
If you want to use voice and data at the same time on Verizon, edit your account preferences to enable Advanced Calling 1.0 for your line. It is free. Also enable Enhanced 4G LTE mode as shown in the screenshot.
But VoLTE seems to bring its own issues: call complete rates will drop, call quality will drop, static bursts occur at the beginning of calls... it's a real mess.
I really miss T-Mobile, but their network isn't as good and I save money being on the family plan with others on Verizon.
Hi guys, I am having the opposite issue.
I can't get VoLTE ("HD Voice") to work. As a result, no internet when I'm on a phone call. A real pain in the butt.
I'm on CM13 on my Nexus 5x and using Verizon.
I had previously activated this feature on the Verizon website, and it shows the VoLTE flag is 'on' in the phone info/service settings menu. I've seen posts elsewhere where people say CM13 is not working properly with VoLTE.
Should I flash to a different ROM perhaps? Appreciate any ideas...

Wifi and data problem

I have a T-Mobile htc 10 and recently updated the phone that was sent by T-Mobile (1.81.531.4). Lately, when I'm connected to wifi and leave the range of the wifi the phone will not connect to the data network. It will show 4g (big icon) with 3/4 bars but there is no connection. I can't send text messages and the internet says I have no connection and the web page won't load.
Turning mobile data on and off won't do anything. I have to turn on airplane mode and then turn it on. That's when the mobile data starts working.
I am having that issue as well. I rolled back and the problem went away. Must be something in that update.
How did you roll back? Are you rooted?
Make sure "Auto switch to mobile network" is checked under your advanced WiFi settings.

I'm also seeing the same thing. Has this issue been resolved? I've just applied "Auto switch to the mobile network" so only time will tell.
UPDATE: applied "Auto switch to the mobile network" unfortunately that did not fix the issue.
My carrier is T-Mobile
Build: 1.81.531.4
I have an unlocked HTC10 and use it on Tmobile, I had that exact problem with mine also after an update which i dont remember the number, but after the last update from last month (1.91.617.1) it got fixed, i was able to make it work with a trade of a little battery life.
My fix:
Go to developers options and enable the "Cellular data always active" that way even when you are connected to wifi the phone will leave the 4g/Lte connection open.
Try that at least until they release the OTA for your phone
Let me know if that works.. good luck!

kelbaez: Thank you I'll try enabling the "Cellular data always active". I'll post back if it works or not. (9/23/2016)
UPDATE: 9/25/2016 Since I applied kelbaez fix on 9/23/2016 phone has not had an issue. Until today.
While traveling (phone was never connected to a wifi) phone seem to have lose connection with T Mobile's data. Enabled and disabled airplane mode fixed it.
However, I still feel kelbaez has fix the issue of being at home and connected to wifi and with his fix I have not as of yet lost data connection. FYI, prior to his fixs at less once or twice a day.
Glad I stumbled upon this thread..been having the same issues. Hope it gets fixed in an update.

cannot turn off Mobile Data

Hello,
I would like to check if I am the only one with this behavior:
I am on stock android 10 version February update.
I tried to turn off the mobile data, turn of the WIFI but Is see that some applications such as whatsapp, still connected to internet and are able to sent messages.
Quora is able to open treads and Chrome still able to browse web sites.
I tried try to disable 4G calls but no changes.
It is a problem for me because if I travel with my smartphone consuming data in other countrys it will be very expensive and plane mode if not a good solution as I need sometimes to tun of data but turn on the WIFI
I am android user since several years and never seen similar behavior before.
Thanks to share your experiences tuning off mobile data with Pixel 3 XL.

With data off what does it say when you enter *#*#4696#*#* and enter Phone Information? Could you give a screen shot? Make sure to blank out your IMEI info before posting. Or just what does it say under the "Roaming" and "Data Service" lines. Should say "not roaming" and "disconnected"
Also, under preferred network type what is selected. I wonder if you are getting 2g or something coming through. When connected with data turned off does it have the same speed as your LTE/4G?
