[Q] LG Optimus Black internet problem

Well recently i bought a LG Optimus Black, at the begining internet and all worked just fine, and now suddenly i cant connect to internet.
I am able to connect to a wifi network, but 3g wont work, how can i fix this?
Every opptions are right.
I tried the same sim card in Samsung GalaxyS2 and some other phone, it works fine. So it has nothing to do with the SIM.

try to configure your 3g network, look for it on the internet.
i only had this problem when i install NOVA ROM, but it was easy to solve the problem.

I have tried but not helping.

Is it running on Stock ROM or NOVA?
Just like lucasmalaguti said, this problem happens only on custom ROMS.
Anyway, just check your settings.
Settings > Wireless & Network > Mobile Network > Access Point Names
Search on the internet or ask your provider for the setting configuration.
Also, if you have a few Access points, Eg. MobileInternet1 & MobileInternet2, make sure the right one is checked.
Download APN Backup & Restore app from market to delete and re-add Access Point.
Once edited/add, reboot phone for changes to take effect.

Check your APN settings
Sent from my LG-P970

I'm running a stock V10E ROM
My APN settings are OK (sent from my provider)
Tried to manually add it, but nothing helps

Today i called LG Service support.
They say that i am not the only one with this problem.
The problem seems to be caused by automatic software update (V10A => V10E).
Only solution is to reflash ROM.
So i did that and now everything works fine.
Thank you all for trying to help!

Hello! I'm newbie

1. turn off your OB and take the sim off
2. test the sim's 3g on some other phone
If it's working
3. put it back in your OB = problem solved
It it's not working
3. call your service provider

I have a similar issue.. but only when I use a Stock Rom..
When I use a CyanogenMod based rom I connect normally.
Any suggestion if there's an option, in build.prop maybe, so I can fix this in a stock rom?

hi, you use a rom from XDA? is it happen after flashing a new rom, first boot, no mobile internet? -> how about some informations about runnign system etc. pp. was it working before with same rom? and so on....
if no internet after first boot: turn on wifi, go Settings/Xperia/Internet Settings , and try download the settings with wifi. how that?
second thought: your provider's fault?

Xperia V is not officially supported by my carrier, but I can use mobile data on cyanogenmod.
I tried to add APN for my carrier, but they don't appear, using APN Manager I could see and try to apply them, only to get an error.
I was willing to go back to stock rom 'cause I wanted to use sony's camera.. but mobile data is essential.. guess I'll to stick with cyanogenmod..

i have added my provider (three uk) network apn manually and it worked.. yesterday.. Now still I cant connect. No reaction at all. I've downloaded settings via wifi and didnt help. Im running official rom 9.1.A.1.141. It is not a provider fault - I used o2 before and it was the same problem. Sometimes restart helps. but not now,
edit. now restart helped.. i dont get it.. This is very enoying

Anyone have any ideia how to fix this issue?
In CM all APN are shown correctly, in any stock based rom I can't add any entries, or it's not shown.

LTE and 3G stopped working?

Hi guys.
So a week ago my Mi5 only want to connect to edge, the LTE and 3G simply wont work.
I tryed everything, forcing it to only use LTE = No connection - same goes for 3G
I have also tryed to reset APN settings and nothing. I contacted my carrier, and they told me everything was fine.
I just tested it in my old Meizu and the LTE works fine. Anyone know what could cause it?
Please help, cause as for now the connection is so slow that without Wifi it might aswell be a flipphone...

Update: I also tryed to install a stable rom using this method: http://en.miui.com/a-232.html
But i cant, i get the "Your allowe to flash the newest stable rom from develop version ONLY"

Try this:
1. In Settings/About phone/ press several times on Internal memory
2. Press Phone information 1 or 2
3. Scroll down and Set Preffered network type as you see on image or chose LTE Ony .
4. Wait few seconds till change has effect.
