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?

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.

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 ?

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

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!

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 ....

I bought it in china but at home the 3G is not working. I read that TD-LTE phone will not work outside of China only FDD-LTE.
I attached a screenshot of my phone is it TD-LTE phone or FDD-LTE?
Thanks
i have LG G2 D801 but whenever i activate Mobile Data connection its still on Edge while 3G is available i can't use 3G what i can do pls help me its my request to all experts
thanks in advance
With the D801 you can select the network mode under Settings -> Tethering & networks -> Mobile networks -> Network mode. There should be 4 options:
GSM/WCDMA/LTE auto
GSM/WCDMA auto
WCDMA only
GSM only
If both GSM and WCDMA are avalable and you are in one of the auto modes and the phone uses GSM (maybe because the WCDMA signal is weak) you can select WCDMA only.

What frequencies does you carrier use for 3G? According to LG the D801 does 1, 2, 4 and 5, which according to Wikipedia are 2100, 1900, 1700 and 850MHz.
http://www.lg.com/us/cell-phones/lg-D801-g2/technical-specifications
http://en.wikipedia.org/wiki/UMTS_frequency_bands
Another possibility is that your SIM card is only provisioned for 2G. I had that happen to me in the opposite way with H2O which only allowed access to the WCDMA network but not the GSM (before they added LTE). You may want to contact Mobilink and request a different SIM card.
can any one help me please.... any expert please help me
i insert my SIM card in my Galaxy Note in my Galaxy Note 3G working fine... but when i insert that SIM card in my LG G2 D801 3G not working please help me bro please
i will buy you a beer
It might be like ATT here in the states where you must notify the provider of the phone IMEI if you want 4g before they can provision it.
Looks like Mobilnk is uses 2100, so it should work.

4G/LTE Pakistani Band 3 1800 isnt present in D801.
So you can get 3G HSPA+ only on 2100MHz...
Check APN settings
Resolved for me
My LG G2 had same problem. Changing DNS or modifying APN not resolve it.
I found reason of problem. After several ROM update, my LG G2 IMEI may be damaged. If you see in Cellular Network → Network Operator, these’s only one record for each operator.
I did backup my imei 2 years ago, now I restore it using LG backup IMEI app. After restore my IMEI, i see two same row operator’name in Network Operator. I can connect 3G again after several months without 3G.
If you did not backup IMEI, you can folowing instructions in forums to restore IMEI. Please googling !

Hi Hyelton, thank you for your reply. The phone does too, its listed on the specifications and it picks up the band and the network when I do a manual search for available networks. when trying to connect it connects to the HSPA+ network not LTE. I believe this is a limitation that ATT might have added. I need someone help me remove it.

AT&T would NOT have a limitation on it. If you do a network search and it comes up, and fails to connect something somewhere else is wrong. Make sure you have the correct APN?
The APN settings have been checked and work fine on a note 3 N9005, somethings up with the d850, can someone help with that please
