Data network not available. (tested several roms and modems)

Hi,
I'm currently doing my community service at a place where the network coverage is very bad and I often get the failure message "Data network not available." if I want to call someone. Sending messages does also not work and other people also can't call me.
To solve this I always have to disable the data connection and restart the phone once or twice.
The failiure message doesn't occure if I disable data connection and set the mobile network to GPRS-only.
I had the same issue with different modems and roms, these are:
JPY, JS5 and JS7 testet with the JPY AND JVE modem.
I can't tell you if this also happens with CM7 or JV1 because I haven't used them at work long enough.
I know that there have been a few threads about this, but there aren't any solutions for this problem, so maybe you have I magic trick for me or we can solve this together?
Btw: I have the international SGS (GT-i9000) and I'm currently running JS7-Rom with JVE-Modem and supercurio-kernel for ext4-filesystem and root access.
nice regards
mike
Ps.: Except for this issue, the phone is really great. I have it for two weeks and I like especially the samoled display .

Looks like your area doesn't have proper 3G Network.

I think we all get this, I know i do. What it really seems to mean is, you have no network coverage from your main provider (calls/text and data), but if you need to make an emergency call I have found another network I can use.

But i have a working normal GSM connection, only 3G/HSDPA is not available everywhere. And I should at least be able to make phone calls if I have GSM connection. (Sendig SMS should be available too of course.)
My old Nokia 5800 with Symbian worked everywhere without any problems.
thank you
nice regards

Does the phone work correctly well away from that location .
jje

check your APN entries make sure they are correct

Hi,
yes it works when I have a better network coverage without any issues .
APN-Entries are the right ones.
What I should tell you is that the 3G network coverage at the place where I work is really extremly bad. Sometimes when you walk a few meters you have a working 3G connection and sometimes not and because I only have to work there until the end of June it's not a big deal but I thought I post it here because it might be a bug in the modem.
nice regards
mike

....you just answered your own question. Just use gsm/edge/2g.

But why does the calling app use the 3G-Connection if GSM is enough?
Better quality?
thanks

WiFi Problem

Yesterday after bricking my phone, I recovered it by going into download mode and flashing gingerbread 2.3.4 XXJVQ but I've noticed that now I'm getting much weaker wifi signals. I only get full bars if i stand like within 5m of the router and I've checked with my other cell phone to check if the router is fine, which it is. So is this like some problem with gingerbread and is there a fix ? Thanks

Try another ROM, maybe a custom ROM... ?

I'd be willing to flash another rom but can anyone confirm if it will fix my problem. Thanks

[Q] Unlocked HD2 Need Rom that connects with AT&T

Hello all I have a PROBLEM!
I have an unlocked HD2 using AT&T, my signal is extremely weak so my thoughts were to add an Android Rom in hopes to increase the signal but I have tried several NAND Roms:
RAFDROID
HYPERDROID CM7
NEXUSHD2 GINGERBREAD
HYPERDROID GBX
ARKAT DOUBLESENSE
REDUX V1.2
I am using the MAGLDR 113, installing using CWM 3.2. I am not sure which radio i have... perhaps that's the problem?
It would recognize the AT&T network and would say registering to AT&T but after 30 seconds or so it would say unable to connect at this time.
PLEASE help I am currently phoneless.
Thanks
PS it doesn't have to be android anything with a signal will work

Try this radio 2.15 its the newest one procedure is the same as installing magldr
1.make sure the phone is off
2 hold the volume button down and turn the phone on
3 connect your phone to your pc thru usb
4 flash the radio from your pc.
hope it helps
in the future post questions in Q and A section or you'll get flamed

Thanks for the link to the radio I appreciate it did not see to help the signal issue. In regards to improper posting that was an oversight on my part is there a way to delete it from here and post in the proper category?

it might just be your location...see if you get better signal elsewhere

Tapatalked u see

rom has nothing to do with the connection you're getting, if you have the latest radio(2.15.50.14) and the proper apn settings for att, then is definitely the service in your area. I have TMO and I get crap signal in my home with any and all roms, but once I'm outside I get good service, plus in data speed you'll only will get Edge/2G speed , but I'm sure you already knew that happens when using a TMO phone in ATT and vice versa .

I'm using my HD2 on AT&T and mine is working great. I'm running Rafdroid Desire HD Froyo. No signal problems at all.

Lets check whether your device is having a loose connection or not first. Put on your wifi, stand some feets away from the router and see if you can connect. If your having weak signal, stand near the router and check. If you still have a weak signal put on your bluetooth and see if you can discover any other bluetooth devices.
If you are having problem with these two connection as well, then my friend its time to open up your device and prepare for surgery.
Else, despite getting full wifi and bluetooth, if you are still having network problems, then place an aluminium foil on the back side of your device in full.
now see if you are having any improvement. These are just preliminary tests to check whether your device needs some serious disassembling.

I'm having the same problem, although I do get connections sometimes but then when i try to send a text or make a call it says network unavailable. I do have gprs data turned off on my phone's account with ATT. I messed with some settings in the phone options after dialing that *# thing and it worked but like i said after one text it just stoppped and when I go into network settings and click att it says registering and then after a few seconds it says unable to connect

After a few more hours of searching I found a way to get a much me stable connection. However, sometimes I lose signal but not like before, when I used to get a warning notification in the taskbar thing. What you have to do is go into the special phone settings by going to the dialer and typing *#*#4636#*#* where it says wcdma preferred you need to change it to GSM only and do a reboot and you should get much better signal.

Is possible to have this WiFi issue?

Hi!
Well, I have a very weird issue with custom ROMs and WiFi.
The history begins last sunday. I was using GingerDX wich is really great, but I had some problems with it, the most important was not being able to install apps in my SD card.
So, I switched to GingerXperia V22, this is a cool ROM too but I really don't like that my music lags when I turn my screen on. Also, the SE default dialer and Infinity view are bad and slow, but I didn't have the problem with WiFi, until I switched to XGin 6.2
Everything worked OK except for this:
El Brillantinas said:
I just realized a terrible and very weird error with this ROM:
I couldn't connect to The WiFi of my mate's office (where Im currently working). But the weirdest thing was the modem worked fine before trying to connect with my Xperia, but after turning the WiFi on, the modem just got busted and didn't work anymore!! So, no internet in the office computers, neither in my iPod, in my mate's smartphone, etc.! It was necessary to turn the modem off and then turning it on, and turning my X8's wifi off to make the modem working properly again.
Weird, huh?
I reflashed, and the error happened again.
So, I flashed back to the ROM I was using before (GingerXperia V22), and now the WiFi is working fine!
Anyone else with that same error or Im the only crazy around here?

I tried kuyaDROID and the same error happened.
I also did a full wipe... And nothing, the WiFi error remains on those two ROMs. So, Im currently using GingerXperia.
So, the question is: Is this really possible? And, is there any solution?

There may be some bug that's overloading it. Also was it the modem or the router? Cuz if it's wifi I would guess its the router but you said modem? I'd just use a different rom that works.

Guess is the router, where the wired networks are connected, it also gives the wireless signal.
As I said, Im sticking with GingerXperia, wich is not causing the error and Im connecting to WiFi with no problems. But I have personal problems with infinity view, SE's dialer and music lagging.
If is about a overloading bug, how could I fix it?
Im using stock kernel, btw.

To tell you the truth, I'm not actually that smart in this, but by overloading I meant that it might be trying to use too much data or something along that line, did it work fine over 3g?
Sent from my LG-VM670 using XDA App

Yeah, I didn't have any problems with 3G.

Don't really have any idea then, I've had problems with mange one device at a time but not fully crashing. Last advice would be that maybe the router has a limit to the number of connected devices it can have and your phone puts it over, try disconnecting one device then connect your phone

I already tried that, and the problem persists.
But this is a good excuse to read and learn eve more, it is a totally new problem for me hehe.
Thanks anyway, for giving suggestions.

I guess I'd try posting in your phones thread and the rom's also, might get better insight into the problem

To further assist you may I ask some questions;
1. What kernel are you using?
2. Have you tried connecting in other Access Point aside from the previous AP you are connecting with?
3. If using custom kernel did you delete all the modules in system/lib/modules?

1. Im in stock kernel.
2. Nope, I didn't try it. I don't have internet in home, but I'd try in my girl's house.
3. same answer than 1.
Thanks for being interested in this curious case.

If your using stock kernel then you shouldn't have to encounter those issues as most roms esp kuyadroid as you mentioned earlier is made for stock rom. I suggest trying into public wifi access and see if you could be able to connect. You have to have two or more access point to test with as router might have different configs than your girls setup.

Mobile Internet connection

Hi, sorry for disturbing, I have a weird connection problem and I am pretty sure it is not the internal antenna... When i use the phone for Internet, mail etc etc.... Everything goes fine it uses a 4G connexion and I almost never have a problem, I do have a problem Sometimes when I am not in a 4G covered area... Than i have to change the network modus to wcdma /gsm automatic because if I leave it on lte /wcdma /gsm the phone is jumping all the time between hspda /h/edge gprs... And this goes fast like that that connection fail... This problem stops when i change modus than I get a stable 3g connection.... A little bit disturbing but Okay..... The biggest problem is that I m always connected with my messenger services like for example WhatsApp.... When i have the phone in my hand no problem at all.... But when he stays on the table or in my pocket it is kinda weird.... Sometimes I don't recieve my messages and than suddenly when I pick up my phone I get like ten messages in once starting from like half hour before.... All this started like three weeks ago, network provider say there are no network problems, I didn't drop my phone or something... Internet connection is just acting very strange lately and this started before I updated to the official 4.4 rom and didn t change after...... I also have to tell that I don’t have problems at all with phone calls or texts messages..... It's just those two mobile Internet issues.... Since i m only good for using the phone and don't know nothing about the technical parts or something... I wanted to ask the question to all of you experts.... And wanted to ask for help and if possible a solution? I want to thank you in advance and hope you guys can help me soon.... Kind regards...

Try different modem perhaps?

Hi thanks for answering.... Tried everything.... Still same two connection problems..... Only thing I didn't do yet was a hard reset.... Could this problem be caused by an application or a bad uninstalled application? Thanks in advance

Hmmmmm, highly unlikely from my point of view, but however there could be some apps locked into 2G or 3G or 4G connection.
Try how clean system doing, if it's same, consider it a hardware problem which there is nothing we can do about it...

samsung s4
i am having network issues
wifi works good
2g works good
3g/4g doesnt work at all no signal if i select these networks
is it a modem issue or kernel issue
