Lg g4 mobile data connection problems - G4 Q&A, Help & Troubleshooting

my g4 can't seem to achieve H+ connection even if it is available in my area.
my phone could only connect with H.
is this normal or is there something wrong with my phone or its settings?

Do you live in Philippines? I am having the same issue, not most of the time. There was some circumstances that my mobile data is not working even when subscribed to a data promos.

yes, i'm from the philippines

[Q] help!3G connectivity has gone from my phone

my phone can not connect to 3G networks in most of our city, while it used to work just fine in these same places. at first i thought there must be something wrong with the carrier's base stations. but today i tested my SIM card on another LU6200(Korean version of Nitro HD) and it works perfectly both on 3G and 2g networks on that phone. but when i put it back into my phone, it can only get 2G signal. if i set the Preferred Network Type to WCDMA ONLY, it got no signal with just a cross on the signal bar. i have to put it back into GSM ONLY mode to receive signal.if i go out, i can get partial 3G connectivity here and there, but not consistently. sometimes even if i have full 3G bar signals on the status bar, i can not make calls or connect to the internet.i've got this problem probably after i tried to forcibly go into the Phone Info menu.i got repetitive " the process com.android.phone has stopped unexpectedly" promps , and i just ignored it and tried again. now ,2 options are missing from the menu, LTE/WCDMA/GSM and LTE Global.in place of them, it's UNKNOWN. i already tried flashing KDZ package of no avail. Does this mean a hardware malfucntion or software glitch?Please help!Thank you in advance

Well you do HAVE GSM only selected. THATS 2G(EDGE)
for 3G you would need to select WCDMA

I just got a N7505 and with Rogers in Canada.
Data connection is sporadic. It will not work for few minutes occasionally and it is getting annoying.
I checked the APN settings and they are correct.
Any suggestions?

What u mean for "SPORADIC"? is it mean the data connection is on/off? how about your sim card line? is it 3G or 4G?

Sporadic as in, it sometimes works, and sometimes not.
Wifi is fine, but mobile data (4G/LTE) is not. With the same SIM card, mobile data (LTE) works fine on LG Optimus G.

In my case... my sim is 3G..but i've set in Mobile Network is "LTE/WCDMA/GSM (auto connect)" at first.. then i found out my data connection same with u.. sometimes on & off... telco company advise me change to "WCDMA/GSM (auto connect)". Since my operator line area still not available for LTE service. After i changed it.. then works fine.
U try to change first, then we'll see..is it ok or not.
Here in U.A.E i was facing the same issue as a work around i go to SETTING , MORE NETWORKS i then MOBILE NETWORKS and in NETWORK MODE manually select WCDMA/GSM as off course i wont able to get LTE but data speed is much better and no signal problem what so ever.
My carrier does not use WCDMA, just LTE/GSM.
Is there a code from dialpad to get into backend settings? For instance, with my other phone (Galaxy Note 1), I can dial *#*#4636#*#* to get into phone settings for more options for network connection.

[Q] Can AT&T be used with a Korean Optimus G Pro?

Hi everyone and thanks in advance for your time.
I have an unlocked Korean Optimus G Pro from the Olleh company. I switched providers to AT&T but it seems that the phone doesn't has access to the Data network provided. I have great phone signal but no Data network (No 4G LTE, 3G, Edge. Nothing at all). Everytime I turn on my data I get the message "Connection unavailable. Configure Mobile Network or Wi-Fi settings to download data."
I understand that AT&T is GSM. But this phone so far is only working with WCDMA only. I've tried switching it to GSM or any ways to make data network available with AT&T but so far it is not working. I checked the WCDMA Service settings but no luck.
Can anyone help me with this? Thanks! :good:

What carrier is this problem occurring?
Have you tried deleting and reimporting APN settings
Have you checked whether the frequency that your carriers 4G Network runs on is supported by the G3?

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe
I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.
AT&T APN settings

After that, it's been using LTE where available.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......
