Losing data connection (NOT wifi but HSPDA, EDGE...)

This is about all the data connection through the MOBILE provider, so not WIFI.
It is after x time when the phone is on. Maybe it is GPS related.
But bottomnline: the icon with the H or the E(dge) is there and it is even flashing for data, however every app stats there is no connection to the network.
After a reboot all is fine.
Other persons are also experiencing this : http://forum.xda-developers.com/showthread.php?t=675786&highlight=huuub
I am using cyanogens latest with one of pershoots latest, but other kernels show the same behaviour.
My guess is that everyone has this problem? Is this a bug somewhere?

This happensto mine as well. I just switch in and out of flight mode to fix it.

So why make a new thread if you've already found one that fits your problem?

I have not that impression. Why do you?

Oh, ok, I should trust you. If you hadn't told me to trust you, I wouldn't have, but now that you did tell me, I do.
I think it's a software issue, as do many other people. Never had this problem with tmobile on any other phone.
Oh, I almost forgot: trust me.

Does anyone here notice it seems to get lost after leaving a wifi connection? Like this bug?

I've experienced this more frequently on Cyanogen roms vs. Modaco's.

really a bug ?
ok guys, I am completely in a stock 2.1 rom .. no mods whatsoever and not rooted as well .. to get this problem, use wi-fi for a while(5mins example) and then disable it .. then use ur gprs/edge and see if it works.. the small E logo will show and the upstream arrow will glow white but downstream arrow will stay dark gray.. both should glow white when accessing the net but it doesn't after using wi fi .. this is really pissing me off having to restart my phone everytime this happens and I use both wi fi and gprs for everyday use .. can someone check to see if this problem is persistent ? thanks ..

Juicedefender is the cause
Ok, I figured out what was causing these problems. And I found out that after uninstaling Juicedefender my Cell connection returns. Anyway Juicedefender didn't seem to do so much for me anyway. (on the contrary I believe)
Can anybody confirm?

[Q] Unable to activate mobile data

Hi community,
I'm a long-time lurker but just until today had the need to join this great place and bother you with a question. I already used the search feature and even googled this problem, which didn't quite helped as I'm still clueless.
Last nite, I switched ROM on my Desire C after being a long time user of Revolution MOD (thanks to @russell664) because sudden reboots started to affect my pone almost daily.
So I went ahead and flashed MiniJBProject (thanks to @penguin449) following the right steps (clean flash), rebooting after install in order to get WiFi enabled and everything seemed to work well until this morning, when I went outside my house and noticed Mobile Data doesn't work. I tried re-flashing ROM, switching between NOPE (thanks to @me4488) and Prometheus (thanks to @nikhil16242) kernels and frequencies to no avail (my pone doesn't go beyond 750 MHz), cleared Dalvik cache, fixed permissions in CWM, nothing.
As I said, WiFi does work just fine but Mobile Data is just not sending/receiving, I'm able to move the slider ON/OFF but get same results.
Then I thought my pone didn't like this specific ROM so I then flashed Revolution JB (thanks to @addictz10) again through clean flash, rebooted to get WiFi, and so on. Nothing. Still the same.
I feel like probably the problem has to do with CM10, since I didn't experience this issues with any of the Revolution Series ROMS.
Any further info you might need to shed some light, please feel free to ask. I'd really appreciate any input.
Thanks in advance.
By the way, I currently have Revolution JB in my pone.

I think you have to enter the apn settings for your carrier. Google for it. Go to settings, wireless and networks, mobile data, access point names, and enter your APN settings.

Most Roms will be able to use mobile data straight off the shelf if using a known, big carrier, for example T-Mobile, however if your using something more local, something not as well none, then you need to add the APN, if your on contract or PAYG with a different company that provides your network service, like TALKTALK uses vodafones, you need to add it otherwise it connects to vodafone, and uses vodafones APNs which, will not work.

Gotcha. Now I know for future ROMS. Thank you @penguin449 :thumbup:

[Q] Data connection

Hey there. I'm hoping that someone can help me out with this. A few days ago I updated to the latest rom from insertcoin. Since then I've had no data connection. Anything that requires Internet won't work. I've spent the day reflashing backups that I know are good but nothing worked. Tried different radios, checked apn settings and mobile data (which says I'm connected) without any success. In a moment of despair I reverted back to full stock hoping that it would solve the problem but again no joy.
At this stage I've run out of ideas which is why I've come grovelling to you guys. I couldn't find any solutions on Google, well nothing that helped. Everything looks like it's supposed to. Internet works over wifi but nothing works on mobile data. Any bright sparks out there with any suggestions ?
Cheers vinny

Thanks for the reply.I don't think it's the sim card cause I've tried it on another phone and it works fine.Hardware failure sounds more likely.I'm always careful when it comes to treating my phone.If I dropped it or something then I'd first think about a hardware problem,but nothing unusual has happened.Could flashing roms actually damage hardware ?

I one time did read about change the tel name in direct wifi to htc one that shold help someone wrote

[Q] [CM 12][Moto X] Data issues and Call Quality Issues

Hell-oh all.
I've been using CM 12 for about 2 months now and something seems to be a constant issue, apart from the in-call UI of course. I seem to be having a bad case of low mobile data. I am getting data, that's not the issue. It seems to be very slow. I have an unlimited data plan and so its definitely not because of me running out of data. Another probable cause could be the geographical location but that's not the case since, I tried using my data connection at multiple place where signal used to be excellent before I went from Stock to CM.
Its also not just my data, my calls also "crack" during a conversation. My only deduction could be that its something related to CM12. Is anyone else facing this issue?

Welcome to cm. The firmware that always has bugs.

Uhh. Ok. Thanks for the help. Which ROM do you use?

I don't face the issues with the latest CM12 nightly, maybe a clean flash would help.
Call Quality/Data Speeds are just fine.

I have had these issues and the first release of cm12 still having problems. Your the first other person to have the same problem.

With the new 21-02-2015 NIGHTLY everything now seems fine, data is back up, so is the calls. The best thing is that Call Bug is fixed!! Yay!

No data. Why?

Hi everyone. My mobile data isn't working. I was on euphoria 5-30 and was working great, but decided to change it up. Tried dirty unicorns, didn't like it, data was fine. I started flashing, chroma then aosip and then the latest euphoria. My data doesn't work. Everything else is fine, but my cell signal icon has a little exclamation mark and I have no internet. I restored my euphoria 5-30 and it still doesn't work. Any help would be greatly appreciated. I searched and found nothing of the like.

I had to restore to complete stock, copy the APN that worked, and input it on whatever ROM I use. Pretty sure the APN will be your issue. I think there's already a few posts about it.

Def APN

Thanks, both of you. I tried that, didn't work. A friend had the same issue and fixed it by registering through the network operator setting. That also did not work. I ended up flashing another radio out of desperation, and it worked. ?
