are you sure you have good 3g coverage? do you have problems with 2g too?

I have good coverage, I am using same card in PC and it is working...Before it was working well with mobile, but now it have some problem..

Try this. It does do the trick for me.
Setting - wireless & network - mobile networks - access point name - new apn
Fill only,
Name : your operator apn
Apn : your operator apn
Good luck!

[Q] Problem with data network - DHD

Hi guys
I have problem after rooting DHD with AAHK with gprs/EDGE data and 3G data. GSM works fine, WiFi, GPS also but I cannot turn on data over mobile network. Tried different ROMs, flashing different radio versions, return to stock rooting again and still nothing. Tried to change APN settings, pull off the battery also but no luck. Also I tried with *#*#4636#*#* to switch radio off no luck. Is there any way that I can troubleshoot this to find out what is causing the problem. My radio version is
12.56.60.25U_26.10.04.03_M
Sabsa Prime V8.0 - tried CM7.2, stock, Revolution HD, Jelly Time, Pacman Jelly... no luck
Thanks in advance for any help

I think the problem is with your APN settings. Something like this happened to me recently and it was because my APNs were messed up. Try this app to save your APNs. Maybe there's some error in what you're manually entering. I see no other reason as to why your mobile data shouldn't work on any ROM, especially if you're getting a signal.

Thanks on your reply. I found that the problem was with my operator, because they disabled the data service for my account. I thought that problem is with my phone but it was on their side. Thanks again

[Q] JellyBean network connection

Hello,
I have the following problem:
I can see the signal bar, but, there's always a 'R' indicated because I'm internetting via Roaming, thanks tele2.
But is there something to see that if i'm connected to 3g or GPRS or 2g ? Like in the Original stock rom.
Thanks,
Mark
edit- even after a reboot there's only a "R" above the signal bar.

Wich rom are you using? Wich kernel? Have you tried setting correctly the APN?

I'm using CM10.1 RC2, Well the 3g data works (also all the others) so i think that the APN should be fine

Then try to reflash the rom and see if the problem persists or just wipe cache, dalvik and reboot

Note 2 No data coverage after 4.3 update?

Just upgraded to 4.3 today but my data services don't seem to function well. Can someone please help me?

Same problem here..

Looks to be an issue with TWRP, have either of you tried the latest CWM recovery? I was hoping to avoid it since my nandroid backup was TWRP (I'm honestly not sure if there's a difference) but a few posts in the main threads are reporting a similar thing.
EDIT: Nope, same issue, at least for omnirom.
I take that back, it does work.

Go to Settings - Network Connections - More Networks - Mobile Networks - Access Points Names
Check and see if you have the APNs from your provider, they usually are 3 ([Provider] Internet, [Provider] WAP, [Provider] MMS - in my case). Make sure [Provider] Internet is selected. When I usually re-install some ROMs, the WAP APN is selected by default and that will show me the 3G data icon but it will not let me access internet resources with my data services.
If by any chance you are missing the Internet APN, search a bit on the internet for your provider APN settings for internet access.
Hope this works.

It just acts like there's no SIM card at all. I don't understand it completely, but CWM is doing something that TWRP is not (or vice versa) and is causing this issue. Took my 7105T from virgin vanilla stock to the omnirom 4.4.2 nightlies yesterday and when I flashed from CWM the issue was resolved.
That said though, I'm unsure how this will affect omnirom's updates so I might need to switch to cyanogenmod. Shame, because I do prefer TWRP.

I don't know what you guys are talking about but I can't even access the APN settings, its invisible. I have a SCH R950 note 2. H2o wireless already took my money but told me I needed to unlock it, even though I can't unlock a CDMA phone. im so confused because it is quad band and has sim card slot but no one can unlock it and I cant find how to flash to h20

LG G3 WiFi Issues.

Hi,
Out of the blue, I can't find any WiFi networks. NONE.
ALTHOUGH, if I enter my network's ssid and p/w manually, it will connect.
What the heck.
I just recently flashed stock, but when I did that it worked flawlessly. I also edited build.prop and deleted some bloatware, but I restored everything back the way it was and it still fails working.
No WiFi network is found. Anywhere.
The weirdest thing, is if I download some random WiFi manager from the Play Store, it finds every network available..
Anyone?
Thanks.

Anyone please?

Another wifi problem
Hi and happy new year,
I have a problem with the Wifi but not the same as you.
It's very strange because I can see all the neighborhood but I can't connect successfully on known networks.
I've tried with many networks with no success...
Sometimes, the wifi disappears and it shows disconnected.
Maybe it's a hardware problem.
Thanks for your help,
AkuaBlue

Another bump I guess.

Have you tried not synchronizing your phone with google account after reset? It pulls list of known networks from server, it may have had affected searching of new networks...

You try re-flashing ROM?

I hadn't.. Do you think that could really cause it not to find any networks?
Also, is there a way of erasing that now? Or do I have to reflash?
Either way I'm going to have to use TB to get my apps and data back.. Do you think maybe that has something to do with it? (I only restore user apps though)
