My 3g seems to have stopped working. Wifi works fine, and 3g works for a few seconds during startup, then the icon disappears and there's no 3g. The icon always disappears just before the second media scan (does everyone's phone do two media scans during startup?)
I've tried uninstalling or disabling various apps, but every time, the 3g is disabled at startup. It initially stopped working while using Google Navigation. One second it was working, the next, no data, and it hasn't been back since, bar a few seconds during startup.
I'm in a major metro area with coverage, that's not the issue. I tried resetting the ATT WAP to default. That didn't help.
I'd really rather not do a factory reset of my phone.
Can anyone think of any options? Thank you in advance!
Have you tried toggling it into Airport mode and back out? FWIW a similar thing happens on my Nexus One and Milestone. I will have a data connection then it just goes away. The only way for me to get it back is a reboot, toggling data off then on, or toggle airplane mode. I haven't figured out the cause as it happens across multiple devices and multiple ROMs. It may be my SIM card.
Thanks, I tried that. No dice.
So I got it fixed. I'll post this in the hopes that it might help others.
On a whim I downloaded several apps that toggle 3g. Both APNDroid and Quicksettings showed that APN was on. Toggling them off and on didn't help.
But Smart Bar showed that APN was off. Clicking APN on immediately made the 3g icon appear, and it worked. Thank you Smart Bar!

So out of nowhere, my HTC Sensation no longer connects to the network. I would get roughly around 5 mbps around my house, but just all of a sudden, it stopped working. I tried rebooting the phone, and turning on/off airplane mode, and it just doesn't seem to be working. Anyone have any more tips before I try and factory resetting? Also i think I may be experiencing a bug because every time I open any app, I get a very quick glimpse of the weather instead, and then the app opens up. Thanks
What was your previous phone with t-mobile? If you don't have an "android plan" it seems that T-mobile is blocking you from data.

I had the same problem two days ago and had to do a factory reset to solve the problem.
Previous phone was MyTouch 3g, so I'm sure I'm on an android plan
Thanks for the link, I'll check it out
Don't assume it's your phone. It's possible that service in your area is down. If you have another t-mobile phone check to see if it has reception. Next go into settings, wireless&networks, and select mobile networks. Then choose network operators and select automatically. If nothing comes up I would call t-mobile because resetting your phone.
On CM7, data does not work at all. I have a cellular signal, I can do calls, text messaging, wifi, and wifi calling works fine. I have tried toggling various settings under wireless settings, so it does not work regardless of GSM, CDMA, or both/auto. I have tried 2G only, which does not work. I have tried disabling any service controlling data, rebooting, toggling on/off.
I followed the guide in the dev forum on installing CM7, every detail. I used the recommended radio. The one thing I was not able to figure out is the APN settings. The APN panel is completely blank, and when I click add new APN literally nothing happens. Resetting to default and repeating does nothing.
I searched the forums to no avail. I'm currently trying various combinations of backups to see what else happens, but I may have to go back to stock.
On another note, I tried flashing the radio again and now I'm in a boot loop. I can't get into recovery because it checks for pg58img.zip and when I select no it just reboots the phone again. I'm away from my sd card reader at the time and obviously can't connect the phone for usb storage. So I'm currently phoneless as I'm writing this.
Help?
Edit: I finally cleared the system data for SMS MMS APM Dialer Storage and the APN showed up. Now it is working. This should be somewhere on the CM7 Sensation guide.
I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

Hi there, just wondering if anyone can help with a small problem I'm having after flashing a new ROM - {ROM}[T][STOCK][JB 4.3][UB&LB][9.2.A.0.295] Official Firmware - Rooted&Deodexed 18/02, by DaRk-L0rD. My problem is that when I first turn on my XperiaT, I usually have no service on my phone - i.e- I cant make calls at all. The phone works fine for everything else, but I have to manually go into Settings-More-Mobile Networks and after a few seconds the phone picks up the signal and the bars appear. If I don't do this it will just sit there for hours not getting anything! I've tried entering the Phone Information menu through *#*#4636#*#*, and setting the preferred method to WCDMA, and I've made sure that in the Mobile Networks settings that is also the preferred method, however it seems that if I reboot the phone, or the battery dies and I switch it on, it randomly forgets these settings and I get nothing. If I try to enter the Settings-About Phone-Status screen when I've no signal then I get force closed, but when I have signal it opens no problem and my IMEI is there and is correct. Also, sometimes the little red missing SIM icon appears alongside the red x on the bars, although this doesn't happen all the time.
It's a small issue because it only happens maybe 80% of the time, and it's not a big deal going into settings and reactivating things, but it's a bit of a hassle at this stage.
Previously I used "[ROM]XperimenT 3.5[T/TL][9.1.A.1.145][Locked & Unlocked][23/09/13]" by TiMiN8R without this issue so I know that the phone/sim are actually ok as it only started immediately after flashing the new ROM.
You can see from my three screenshots that I have no service for two minutes, enter the mobile networks menu, and finally after being in that menu for a few seconds up pop the bars!
If anyone can help me out I would really appreciate it.
Sometimes my WiFi goes away, LTE kicks in for a second, and then WiFi comes right back. I don't know for certain, but it may only happen when the phone has been unused for a while, right after I first pick it up to do something. But I have the WiFi power saving option turned off, so that WiFi should stay on all the time. And I seem to recall it happening just at random sometimes, too, in the middle of browsing websites or social media apps. It'll say "no connection" and I'll look up and see LTE kick in, then WiFi come right back, then I'm all good. It's very annoying.
On top of the quick WiFi cycling issue, sometimes WiFi will just completely stop working. When I go into settings, it says it's disabled and I can't turn it back on. Going in and out of airplane mode fixes it. This only happens about once a week or so. The other issue is by far more annoying.
Anyone else experiencing either of these? I'm on Verizon with a black 128 GB stock, unrooted, if it makes a difference.
Thanks!
I personally haven't seen this on my VZW Pixel although I use it with T-Mobile service. These are as suggestions only, and it may or may not help, but you could try using any order below.
1) The setting to keep WiFi during sleep is on, right?
2) Have you tried to use your phone without sim card in it and see if WiFi is still acting strange?
3) I would also suggest to go to Settings>Google>Networking and see if you have WiFi assistant on or off. There is a setting under advanced as well.
4) Does it happen on all WiFi networks or when using on particular one? You could forget that network and then join again.
5) Alternatively you could "Network settings reset" under Settings>More>Network Settings Reset - after the reset, you may need to rejoin all the networks, pair Bluetooth devices and so on.
