Stuck on 2g - Xiaomi Poco F1 Questions & Answers

Hello
I have been using Poco on t mobile and had 4g and 3g without any problem.
After data plan was finished (I think), I was stuck on 2g network. I topped the balance but I am still stuck, however when I swap cards it works on other phones and I am still getting 2g.
Any ideas?

Try wiping Dalvic and cache in Recovery. Or dirty flash the ROM.

why does the atrix have such a hard time switching from H+ to EDGE?

i have spotty 3g in my area, so my phone is switching between EDGE and 3g allot. for what ever reason, it completely looses signal to switch over. i have had many cell/smart phones and all the other ones switch over without loosing signal. it is really getting annoying, but i love my atrix. what is the issue? i STILL have not found a way to disable 3g and just use EDGE...4636 does not stay.
the other thing i have not called and switched my plan to the 4g plan yet, i have a BB also and i am still on a BB data plan. i DO get h+ on my phone, so by getting the 4g plan, will this stop this signal loss from happening? as i said, i could care if i had 3g, im fine with EDGE since im on wifi.
any help/advice would be greatly appreciated..
thanks!
There is no 4g plan since its not 4g. Its still a 3g network so if u have a 3g plan then you are on the fastest that att has to offer. Their 4g claims are a farce

try a new sim card if your card is over 6months old. when i select gms only in that service menu it disconnects from the network for a few seconds then locks on edge and stays on edge
I have this same problem too on a regular 3g data plan so I don't think it's bb related. it bothers the crap out of me

Really....humming....I am using my micro sim from my iPhone with the sim adapter....maybe a trip to AT&T for a new sim is in order
My iPhone 3GS had this problem, my Atrix does too, but it's not nearly as bad about it.

[Q] My DNA has mobile data connection problem

After the update, my DNA starts to have mobile data connection problem. Often it shows mobile data disconnected. Turn off then turn on does not solve problem. After restarting, it shows 4G LTE, but I can't connect to any website. Then after several minutes, the symbol changes to 3G, and I can now connect to internet as normal but at 3G speed.
I have taken out the sim card and put it back, still same problem. What may be the cause, what should I do? Thanks.

what area are you in. Is it normal for it to switch to 3g (ie you're in your house)
were you rooted prior to ota and if so what were you running.
what kernel did you have installed. and what kernel is it saying right now ( ie [email protected] or custom)

i would call and have them resend you the ota and try the flash again. It sounds like while flashing the new radios it either did not finish or didn't not flash at all. Seems like the 3G portion of the flash worked, but not the 4G. I had this happen on the rezound only the other way around. The fix was the roll back my phone and reflash the update over. Since you do not have the capability to roll your phone back. Try the ota a second time.. I'm guessing they are going to tell you it's not possible to send the ota again since the phone is going to think it's updated. So you may end up taking it to a store and having to send it in.
Same thing happened to me. You'll more than likely need a new SIM card.

LG V10 4G LTE connection problem

Hi,
I have been experiencing a few issues with the 4G LTE on my LG V10 H901 (T-Mobile). What happens is this.
In Network mode I selected GSM / WCDMA / LTE Auto. This initially worked fine and could get a data connection. 2 days after, I noticed I couldn't get a data connection anymore, the 4G LTE icon at the top was displaying with a down arrow lit. So I went in the Network mode and checked my APN everything was ok. Decided to switch from GSM / WCDMA Auto where I got a 4G connection (icon 4G displayed at the top) and I finally got a data connection.. Changed it back to GSM / WCDMA / LTE Auto, and there I was back on LTE... I had to reboot my phone and that is when I noticed the same thing happened again!!! No LTE connection and had to first select GSM / WCDMA Auto to get 4G.. If I reboot with GSM / WCDMA Auto I get a data connection fine.. The problem only occurs when I have the Network mode on GSM / WCDMA / LTE Auto. Anyone else having this issue? Is there a fix?
Thanks
I would say it's a hardware problem with the phone I've had mine for a month i never touched network settings and the phone gets a better data connection then any phone I've ever had LTE pretty much all the time where other phones wouldn't maybe a factory reset would fix it worth a shot
The first V10 i got from T-Mobile had somewhat of a similar problem but with WiFi, it would connect but speed was horrible. And LTE isnt that great in my area either. I read around the forums and notice that many have done factory resets and that fixes everything. I did that and lowe and behold, it did. WiFi was fast again and LTE speed improved but still sucks....its my area, not the phones fault. For some reason, a reset helps.
However, I was still just 4 days in since I got my phone so I just went back and had them replace it. I just told them that the WiFi doesnt hold....they didnt really ask me tons of questions. I replaced it only because I am paying for the phone and me having to do a "fix" to make it work doesnt sound right...so I want a new good phone lol. The new phone worked fast from the get go...no reset needed.
Just got the V10 was having those wifi issues initially so brought phne back n exchanged for another 1 and this 1 workes fine but now Im having dropped call s inside my house ,verizon said no antenna issues i can bring phne back n replace for something else or another v10 but that is time consuming ,please anyone having drop d call s....I live Long Island NY so verizon overage is better then most carriers...INaNYmin...
I began having the exact same issue on Jan 16. Had the phone since Dec 25th, worked perfect. Then, all of a sudden, it began to lose LTE connectivity. At first I thought it was a down tower, but the problems persisted an eventually got much worse wherever I went. On a full charge the phone will behave normally for a while, but eventually it starts losing data connectivity altogether, cycling between 4G LTE, 4G, 3G, 2G, trying to connect. during this process the battery drains a lot, it never really connects, and sometimes calls and text messaging fail. Tried every network setting, soft reboot, hard reboot, safe mode, clear cache, factory reset....problem persists. T-mobile concludes it must be defective. We shall see. Awaiting a replacement.
Having the same issue. Looks like it's a common problem. Any fix for this yet?
I have a similar issue.
it always seems to find the LTE signal, however I have no data and the battery drains very quickly.
If I have it on GSM/WCDMA/LTE, it seems to have connection issues. However, the data will connect on GSM/WCDMA. Once I have data, then if I select GSM/WCDMA/LTE, and it will connect to LTE
It is a Tmobile version. I am using it on Bell (Canada)... however it works fine with Wind & Tmobile, with no issues.
I am hoping that this will be fixed with the Marshmallow upgrade.

Wind works on hspa not LTE. That's why it works. I've noticed that it works fine on hspa(4g) but when I put it on LTE(4gLTE) it works for a while then stops.

For me, Wind works fine on GSM/WCDMA or GSM/WCDMA/LTE
With Bell, it will not connect on GSM/WCDMA/LTE.
However, with Bell, if I put it on GSM/WCDMA, it will connect. Then if I change it to GSM/WCDMA/LTE, it will connect to Bell's LTE.
Occasionally, it will lose its data connection... and then if I toggle between GSM/WCDMA & back to GSM/WCDMA/LTE, it reconnects. This seems to happen once every 2-3 days
I don't know why it does this. It was actually very frustrating until I figured that out. I almost dropped Bell because I was not able to connect on LTE for the longest time!!
I just keep my Wind plan for the US roaming (on Tmobile LTE down there)

Yup exact same issue with me and that's how I resolve it as well I'm with koodo and I lose LTE. I was going to warranty this phone but I think it's a common issue.
I just want to quickly point out that I am seeing the exact same issue on Virgin Mobile (Bell). I also noticed that the performance of the phone decreases drastically when it is connected through mobile data instead of WiFi. Anyone else sees this and knows how to fix it?
Lg v10 t mobile no connection
I'm having a similar issue I get a 4G LTE signal but if I make a call once I end it I loose all signal including the bars it wont let me text or call it says network not available and it will do that till I travel a few miles. I'm not in a dead zone because it does it in the heart of the city and on the buisest streets in Tampa Florida then it will come back and sometimes I won't get a signal for a entire day out shoe have any solutions?

Hey,
I'm using this phone in Canada too, on Telus. Ever since the OTA update 2 days ago I've been having data connection errors over the network. Did you find a fix?

I'm seeing this too, but it just started after my OTA update. So frustrating bc I love the phone.
I had a similar problem. With The latest software (,,v20c,,) With the LGUP Software I software put it back (,,v20a,,) . And it seems the problem disappeared. Last part of the modem software is not good. Even test elements. Sorry for my bad english for knowledge. LGUP software very simply . ( i have V10 960A Unlocked (Eu version) android 6.0 and T-mobile LTE )

4G problem

Hello to all.
I have some data issues with my Z2.
I'm on t-mobile HR (croatia).
So, if the phone is set to preffer LTE data network and when I leave WiFi network the phone can't connect to data network, if there is no LTE network. Than I must set the phone to preffer 3G, phone connects to 3G or 3G+, and than to 4G when I set it to preffer 4G again.
When the phone is set to preffer 3G than if I leave WiFi the phone immediately switch to 3G.
In both casses, after the data network is found (3G, 3G+) and I set the phone to preffer the LTE phone switch to 4G.
I foud this problem since the phone is updated to 4.4.4 Kitkat and now I'm on 5.1.1. Lollipop (.264 version) and the problem still persist.
Please help me to solve it because it's really annoying.
And yes, the whole area is covered with 4G signal, but sometimes is weak.

well, I don't feel confortable with rooting my device and flashing custom software..it would be great to solve the problem without that

Can't Use 2G EDGE or GPRS

I've had this problem since last few months, but since I'm always on 4g or 3g, I didn't bothered about it. But, now I'm using BSNL which doesn't have 3g coverage in ny college campus. And now this is bothering me since I can't even load my whatsapp messages or open any link. There's no problems on 3g and 4g networks. Also the 2g networks works great with calling but when I switch on my mobile data connection, it takes around 10-20secs to switch it on. Later, no packets are transferred from device and I can't use internet.
This problem started when I messed up while flashing and got my imei lost. I managed to get them back and have flashed the firmware multiple times since but this hadn't helped with anything. I had fp issues too but everything is solved except this no data connection on 2g.
So, please tell me if anything can be done or you did to get out of this situation.
Thanks.
