Have you made sure you have the APN set up correctly??
Also check the Mi4 supports the 3G frequency that your network runs on.

That's strange, I didin't have to select any option at all. It worked on O2 network in UK straight out of the box after I set the APN.
I can post a screenshot of my network settings soon if you want, my Mi4 is charging at the moment.

I dnt know what the problem is please help me.

Try another providers SIM card.
Edit: Just read you already did that.
Sent from my Xperia Neo V using xda premium

Hmmm, try this;
Settings > Mobile Networks > [Change to 3G/2G]
Just to see if it'll work in the phone, seeing as the SIM works, maybe it's the phone.
Then try;
Settings > About Phone > "Tap" Internal Memory 5 Times > Phone Information > [Change Preferred Network] (Reboot)
Let me know if these things work, also let me know your provider and if you setup your APN info correct.
Thanks!

Oh, lol, also. On AT&T I have my preferred network set as [GSM Auto] and that works fine for me.

3g not working on xiaomi mi4
Hi .
I am facing the same issue . When i try to change preffered network type as wcdma in phone information and reboot it automatically changes to default one. Rest all settings are fine . Please help.
Thanks
Rishab

You don't need to reboot, just save the settings. AFAIK.

Hi,
I tried to save it. but how to save it. there is just option of selecting preferred network type as WCDMA preffered in Phone Information but it does not get saved. And in the mobile network setting i have already selected preffered network type as 3g. but it doesnt work.
Please suggest. thanks
Rishab

Just select the option and back out of the menu. Seems to work for me.
Screenshot?
Also, what carrier and plan?

probem
there are more versions of 3g ... there is a 3g china and than 3g unicom that should be identical with the 3g in europe ...
also there are 2 versions of LTE too ... am afraid you picked the wrong package there mate :/
google it that kind of 3g technology you use !!! and what is supported in your country
EDIT >>> .... Look for the Mi4 WCDMA version for Europe and at all costs avoid the TD-LTE/SCDMA ....

could you provide a link to the exact version of the phone you buyed? As mentioned before, there are different versions for different basebands around.

hi I use TDD-MI4-CMCC version with 2gb RAM. Also I want to catch basebands signals of WCDMA but my phone seems to be locked with TD-SCDMA signals. it catches GSM signals well but not WCDMA signals.

Nexus 5 3G - not finding operator

Hello,
I bought a new device, Nexus 5 from China
And I have a problem when I insert SIM regardless of which provider I have no reception (no service),
Tried to set the correct APN settings with the provider but it didn't help.
It works out only when I'm working on 2G when I return to 3G again no reception. (No LTE in my country - Israel) .
I can't find any operator after switching to 3G.
when I switch from 3G back to 2G I still can't find operator only after a restart.
Do you have any data about my problem? and how\were can I get service support in my country? Thank you.

Same problem here...anyone?
Well, depending on your operator, 3G frequenties used maybe not the same as the ones uses in China.
I know that USA LTE(4G) isn't the same as here, in France (If not I would have bought it in USA for 349$, that equals to 255€. And I bought my N5 349€ in the play store)
Try to call your operator and ask them for the frequenties they're using ?

[Q] No 3G/LTE signal. only G

i have problem with my data connection. when i set the preferred network to WCDMA only and LTE only. my phone has no signal at all. i have a strong 3G connection on my other phones.
is it a baseband problem?
if it is. how to flash the correct baseband for my F350L?
or this maybe a hardware problem?
thanks guys. appreciate who will help

I see that you are from Manila and using a F350L please check supported bands by your network and the supported bands of F350L if they are compatible.
i did check it and it is same bands use here. there are f350L users here with no problems using their 3G connection.
My F350L is LTE-8 other F350L are LTE-A. I suspect that this two have different band
I am having the same Problem up here in Ohio
No matter what I try I can not seem to get this phone to do anything besides just G I am running the F350S on AT&T
Please look in Dialer with 5457#*350# and activate your Bands
Still no dice

Hi folks, I am Nigerian and I use an LG G Pro (D838). Some days back i noticed that i had no network on my phone so I tried inserting another sim into the device and still got the same result but other devices around had network coverage. I changed the network mode to GSM only and got 2G but WCDMA only gives me nothing. I have tried other sims on GSM only mode and got 2G but when i change the mode to WCDMA only, i get nothing at all. Have also put it to GSM/WCDMA auto but keeps giving me just 2G network only. I have even had to downgrade the OS from android 5.0.1 to 4.4.2 as suggested by a friend and still got the same issue. Please, what should i do??????
Same problem overhere Lg g pro 2 though F350k
I have the same problem in Holland. I have the F350k variant) 3G is in Holland 900/2100. The phone has despite of the advertisement text !!! by selling (900/2100) 850/1900/2100. The 2100 band is the same so should work.
Tried a lot. By the way last software and Androi 5.0.1.
The Sim is not the problem, the APN setting not, ........
any suggestions?
Could it be somewhere oleh software??????

Hello, I am from Nigeria.
I bought my LG D838 on eBay in May 2015 and was quite impressed with the performance but my pride and happiness was short lived. I woke up one morning in December 2015, and noticed I didn't have any cell reception. I checked with my siblings and I seemed to be the only one who had no cell reception on the same network as theirs.
I swapped SIMS of other networks into my phone but still to no avail but funny thing was that whenever I change network mode to 2G only, I get reception but switching back to 3G only mode gave me nothing at all...this happened a few days after I updated the OS with a 50MB patch file using OTA as prompted. I have been writing to LG since then but no reply and it has frustrated me so much as I bought this phone for about USD 398 and didn't even get to use it up to a year. I managed it on 2G while trying to contact LG about it until the Wi-Fi and Bluetooth stopped responding also. I need the NV and QCN backup file for this phone in order to get it running again…I would really love to see this beauty run again. Please help me out.
You can contact me or send the file to [email protected]. I am open to suggestions.
Thanks in anticipation.

can't connect with 4g, only 3g

Dear friends, I have Nexus 5 but 4G doesn't works . My service provider supports 4G service at 800MHz and 1800MHz as it shown here http://www.gsmarena.com/network-bands.php3?sCountry=Morocco , but my nexus 5 d 821 does not work with 4G, I want to ask that if there is a solution like a roms or others things.
Thanks in advance.
800MHz and 1800MHz are LTE bands 20 and 3 which are supported by your device but those information are for Morocco. Do you have the same information from your carrier?

sometimes the phone loses signal and switches to ''emergency calls only" mode even when i force switching to 3G by typing *#*#4636#*#*
If anyone you kno how to solve this problem or anyone else here do,could you possibly help me out with this.

hi friend, nice to meet you
i will try to give you a summary of what i reached in the end.
first thing, i discovered that the nexus 5 that i have is not a D821 but it's a D820 means it's the version especially for USA networks, and this mean that 4G of USA networks works on different bands than ours in Morocco, so after finding exactly where the problem, i began looking for a solution and i found this: http://forum.xda-developers.com/google-nexus-5/general/radio-enable-lte-band-3-nexus-5-d820-t2928561 and after application the lesson, i got the 4G connection on my phone, and it's work very well till now.
this is my story, and i think it's a little different than mine.

i'm glad you answered.
and i'm glad you figured that out and solved your problem.
my case is somewhat different from yours.
before enabling those bands,you never caught 4G signal.
but for me,i do get 4G signal and connect to it,i access internet data, surfe,and make calls,but it's only when i'm near a 4G network tower.
which means the band is already activaed,it's just a deal with the signal strength.
if you can help me,i'd really appreciate that.
i'm really confused wether to flash those drivers or do something about the radio,cuz this problem brings about another problem which is battery drain,
my battery drains faster cuz the phone keeps searching for network.
just to let you know,when i go to bootloader it says Lg nexus 5 D821 (H)

Dude,you won't believe this !!
i just removed the back cover of my nexus 5 and was freaked out to find out it was actually an american model D820
thought the fact that in fastboot mode( bootloader) it says it's a D821 (H)
and guess what ! that (H) confused me and made me doubting it to not be a global (indian) version.
i guess i need to flash Some bands to get my LTE working properly.
thoughtless it's working but only when i'm near a 4G tower !
please help me.

hey bro!
how are you doing ?
i hope you are fine[emoji4]
sorry for this long escape ( been so freaking busy with exams and preparation )
i really am confused with this device !
i thought it to be a nexus 5 model D820 because it can't catch 4G properly , then i removed the back cover and found it's A (D820) then went to regulatory information like you said found it's a (D821 )
went to fastboot mode found out it's a (D821 {H} )
i'm freaking confused.
i used an app called ''LTE Discovery'' to identify which bands my phone uses to connect to 4G when it catches it, i found band 3 and 7 !
do i still need to enable any additional bands like 7 or 20 to get 4G working properly ?
waiting to hearing from you soon !
sincerely,
Zackaria.

what concerns us is what there is within the system and not back cover, so depending on the picture attached and what you said, the version D821 should run 4G, because the bands necessary are already exists. did you tried other SIM cards ( maroc telecom, meditel, inwi ) ? what did you get ? the same problem ?

i'm using ''maroc telecom'' thought i tried other Sim cards nothing has changed.
i tried inwi. it works well !
i don't know if i still have to activate any additional bands like band 8 and 20 ?
i talked to the guy that have posted the video in youtube and said that i need to activate band 20 if it isn't activated yet.
then talked to developer ''azlun'' who first succeeded to activate band 3 and 20 and said that if band 3 is already activated , but 4G still doesn't work properly , then i need to activate band 8 and 20 which is impossible due to hardware limitations.
what i really need to know what bands are used to connect to 4G in morocco ?
i already have band 3 and 7 activated.
if i have A D821 what others do i still have to activate ?

as i know in morocco, the telecom companies use 1800 Mhz and 800Mhz for LTE connection, which means bands 3 and 20, so the global version D821 has bands 3&20 already exists,and the two of them and you don't need to enable any bands! take a look here: D821 LTE bands : 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800).
did you do this step ? calling service client of "maroc telecom" on 888 and tell them that the 4G doesn't work on your phone, and the will activate 4G connection for you, although you have a 4G SIM, you have to call service client of maroc telecom on 888 to ask them to activate LTE connection

like i said,
my Sim card has already 4G network.
i already called them.
the problem has to do with my device.
now, you just said Nexus 5 Model D821 has band 3 and 20 enabled.
and i tell you i used an app called LTE discovery to find out which bands my phone uses to connect to 4G i found band 3 and sometimes band 7.
if it's the global version why it doesn't use band 20 ?
maybe i need to enable band 8 or 20.
imma call service client f maroc telecom tomorrow and ask them which bands they rely on.
then, imma be taking the next step.
i will really need your help bro.
and excuse my ignorance.

verify that you are in a location that gets a good signal and that it says you get 4g lte data. then goto connection settings>mobile networks and tap on network mode and choose the option in the screenshot. if it doesnt change do a factory reset. if that fails either get the stock rom from sammobile and flash it with odin or call samsung for a replacement. also verify that theres no upgrades or problems in your area by calling customer care and that your house doesnt limit your signal. my house sometimes limits mine due to it being metal all around. in that case putting your phone in a window fixes it. if you want to avoid that contact tmobile to get a signal booster for your house. update: in the *#2263# menu make sure to choose reset on both LTE and WCDMA in disable band.

This phone doesn't have certain bands asia uses. you may need to buy the sm-j327u (samsungs unlocked version of this phone that can work on cdma and gsm carriers.) the sm-j327t1 was designed for the united states.
to fix this problem install (Force Lte Only).apk from play store go to phone information>Network mode>Select WCDMA ONLY!
it will fix the problem as well as you'll have all option enable i the network mode!

Need some help here, still stuck on 2G. Though I don't have a T-mobile sim card, the device is said to be unlocked (by @ashyx ), so I want to use my sim card. So what am I supposed to do (I've tried everything listed here so far, no luck)?

Orange, like in the other thread. APN set to default also, just in case.

Have you checked which bands your network supports against the bands your device supports?
You may have to open the network settings and modify the bands if possible.
Also which firmware are you running, you may need to flash the modem from the orange firmware?

I'm going to assume your carrier is an MVNO such as Metro PCS, the most problematic carrier with this device? If not, what carrier do you use?
Most of the times the fix is pretty simple. Go to Settings > Cellular Networks (make sure under Preferred network type LTE is selected) > Access Point Names and chose your correct APN. Is it jumping back to the incorrect one? Delete that incorrect one and any other ones that are related to the "parent" carrier and then chose the correct one. You can delete it by going into the APN as if to modify it and tapping the 3 dots on the top right. Can't find your carrier's APN? Delete all APNs one by one, then add yours, save and and select it.
If the above does not work, ensure that the OPO supports your carrier's bands, specifically for LTE.

What is the name of your carrier and in what country?
The name of my country is united king down and my carrier is tesco mobile

Sorry for the late reply. According to information I find on the web, Tesco Mobile uses Band 20 for 4G, which the OnePlus One does not support. Other websites mentions it using Band 40, but I believe this is based on the fact that O2 (the parent carrier) has obtained this band and may not be fully implement on the MVNO (Tesco Mobile). I would suggest calling them to find out what 4G/LTE band they use. If they use Band 20 (frequency 800MHz), you will only get 3G, or HSPA/HSPA+ (H or H+ icon for your data on the top right). If it supports Band 40 (frequency 2300MHz), then we can try and see what is going on that may be stopping your 4G/LTE from working.
they use 800
mhz

Yes, sadly that means Band 20 for 4G LTE, which the OnePlus One does not support. You will only get 3G. Some carriers call HSPA+ "4G" because it can achieve decently high speeds for video streaming and so on, which isn't bad.
