[Q] Cant connect to mobile data network

I can not connect to mobile data network.Wifi runs normal but mobile data does not!
Checked my SIM in other phone and mobile data works!
Also this happened to me since I updated my phone using PC Companion and I put a new ROM in hope that mobile data will work but no :/
Also I have downloaded my carrier network settings!
MY rom now is Xperia Ultimate HD™ 2.0

You are turning off your wifi right?

Check your Carrier internet settings. APN, IP.
There are something you can do. Some gives you auto config when you text them with some code. Try googling your carrier 3g hsdpa internet settings.

Yes I know I how done that and received the installation over SMS and installed it but nothing,also tried manually configure it and also nothing :/
Would maybe flashing a baseband help?

You can find them under
settings-xperia-internet settings. Tap that with wifi on and mobile data+roaming activated
Flashing baseband does nothing to have with this

What is your phone model number
Sent from my LG-E971 using xda app-developers app

Pretty sure you have to setup your APN's again in mobile network settings. Jellybean will wipe your phone completely if you didn't backup your phone settings before. Check what the APNs are for your service provider,

Sony Xperia Ion LT28h Internet

Hello I'm a new Sony Xperia Ion LT28H user. My sim is sun cellular and its GPRS can't be activated. What are the settings and what should I do to be able to use internet on my phone. Please help me. Thanks!

You need to configure your carrier's apn settings to enable data.
Sent from my LT28h using xda app-developers app

thanks, but how?

I think its settings/xperia/
Btw, gprs is not mobile internet, its for ur location.

Settings>more(after data usage)>mobile networks>access point names. You need your carrier's settings though. Google them. Afterwards save the apn and tick enable data.

I think you're thinking GPS. GPRS is normally associated with 2G or 3G which doesn't use HSPA.

You're talking about gps Gprs is an old internet service LT28h uses HSPA+ or LTE

First of all confirm from ur carrier that gprs is activated or not, if yes then go to settings - xperia - Internet setting, it will automatically download the settings

I went to a Sun Cellular service center and they said their system is offline and it seems they are having problems. By the way when u said LT28h uses HSPA, does that mean that other procedures should be done to enable its mobile internet? Does it need a software to be installed?

It doesnt need new software, hspa is 3g internet(gprs is old very slow connection internet). To enable it just add your carriers apn settings

No it doesn't! When you start your device for the first time it tries to download the internet settings from your carrier try to turn off and then on your mible data in settings -> more -> mobile networks :cyclops: take the tick out from "Data enabled" then tick off it again if it doesn't work then write, I'll try to help!

[Q] I messed up with Titanium Backup and now it says 4g, but data doesn't work

So I had to get a replacement Note 2 from T-mobile because my first one had messed up sensors or something. When I got the new one I wanted to backup and restore all my apps from the original.I used Odin to flash CF auto root and do a app and system backup. Then I rooted to the new one the same way and did a restore. I apparently didn't read enough about Titanium backup and restored everything including the system stuff.*Now my data doesn't work most of the time. Specifically when my phone says 4g, no matter how many bars, nothing has network access. I can make and receive calls and text messages although calls have been very spotty with reception. However if I have 4g LTE signal then everything works great. Can anyone suggest a fix? I flashed the stock rom again and reset APN settings to default, nothing is different. Side note, I was able to reset flash, unroot and return the old phone to T-mobile. Any help is greatly appreciated

Have you tried a factory reset?

I did do a factory reset after flashing the stock ROM. Both through the settings menu and by booting into recovery. No change.

Am I really the only one that has had this problem with titanium backup? I read a lot before rooting, but apparently not quite enough. Please, if anyone has any ideas or has had this problem, a little help would be greatly appreciated. I would hate to have to send back another phone espevially one that is otherwise perfect. Everything is great when im on wifi or LTE, but 4g gets me nothing. Thanks

I don't think that this video is related to my problem. I can make and receive calls and texts with 4g or lte. However I have no mobile data connection whenever I am connected with 4g. All apps report no connection. When I have lte signal all apps work with no problem. Also my imei number is not gone, it is in there correctly.

Just an idea here. ...
Do you have an Add Block app of any kind? If you do, try to turn it off and see if that is the problem.
I had one that blocked my data, but only on Wi Fi. It took me several days until I found the problem.
Good luck.
Hit my "THANKS" button! Come on, you can do it!

i had similar problem
my settings were set to LTE only in factory menu.
so i would get internet only if LTE signal was available.

Have never had an adblock app of any kind. I know for sure that the problem was caused by me restoring all system apps from titanium backup.

Have you tried flashing the radio?
You would have to flash a custom recovery (recommend TWRP)
I also had that problem on my Nexus 5 for a few days, I upgraded my ROM but forgot to flash the Radio again, and after flashing radio in custom recovery all was fixed, was strange because SuperSU carried over and it was just a delta (65mb) update, must of screwed the radio I guess. All is working now though.

#cjp420 did u find solution, i have same problem

I did not, but I never tried flashing the radio like the previous commenter said. That actually was an idea I had, but didn't try because I asked and people were adamant that I shouldn't do that.
Believe it or not I am still using the same phone still with the same problem. It's not a big deal because I set it to only connect to lte or gsm so it never connects to the regular 4g. Everywhere in and around austin that I tend to go has good lte reception so I don't really miss it. The only part the kind of sucks is that ot switches to E whenever make or receive a call because there is no voice over lte apparently.

[Q] Problems with LTE

How can I disable LTE. I have tried a few suggestion from this site, and havent got it to work. I am not tech savvy at all.
I went and got at&t service in December 2013 and bought the LG G2 phone and loved the phone. Everything was great with
The phone, data speed and connections until April 12th. I was not able to load any web page, and when on facebook it would
not update the page. It would tell the that I was not connected to the network, when I had all 5 signal bars. I also noticed that it also
now said LTE under the 4G. So they sent me another phone (lg g2) and I still had the same problem, so I then went and got a new
sim card, and that did not fix it either. So they sent me another phone. So now I have the LG OPTIMUS PRO E980 . I also figured out
that the only time I am able to use data is while I am on a phone call. And when i make a call, it changes from 4g LTE to just 4G. So
I called at&t to ask them how to disable LTE and they told me that they couldnt tell me how to do it because they dont support it.
I work from home, and use my phone for work, so this is really hurting me. What isbreally weird is that I have a tower about 1/4 mile
from my house. I am sorry for such a long post. I am not tech savvy either, so alot of whatvyall talk about, I have no clue what
it means, lol. Like rooted, bricked and flashed. HELP PLEASE! Thank you in advance.

Under settings, mobile data, is there a place to select "preferred network type"? I remember it being there.
On cm11 it can be selected, either LTE, 3g, or 2g.

Hello, and thank you for the response Abumy.
Yes, the option is there, but it is greyed out
and will not let me select it.
Anymore suggestions, please??
Thanks so much

Have you tried changing the APN.
Its in setting/tethering & networks/mobile networks/access point name..
Once there click your menus button and add Apn..
Input the info listed below. One of these should accomplish what u want. Oh and make sure after you enter the apn to hit menus and save.

There is an an app that will let you set it to 3g, but it seems to require root on some devices:
https://play.google.com/store/apps/details?id=com.cc.signalinfo.
On some att phones dialing *#*#4636#*#* can give one access to these settings too.
I am not running stock and not on att, so I cannot test it.

What about APN'S for the LG G2 phone? I have to
send one of the 2 phones back, and I would much
rather keep the LG G2, if I could figure a way out to
not have to use LTE. I really appreciate everyones help
here!!!

The apn would be pretty much the same wouldn't it?
