Hello,
I have a problem with my HTC S730. The dataconnection in connmanager is turned off. But I can't get it back on. It works for half a year but now it won't work. So when my dataconnection is off I can't call or sms.
I tryed a hard-reset but without result...
Any suggestions?
I don't understand. You switched off phone at commmanager - maybe. After restart will be GSMpart fix at switchoff.
Do you go to commmanager and switch phone to on. You don't need dataconnections for SMS and call.
Maybe you switched on airplane mode. It isn't possible use GSM on airplane mode.
If you have switchon GSM, you need setup GPRS or dial-up at settings->connection. You will ask yours network operator.
If no,
Maybe you have problems with yours SIM cards, maybe you have problem with GSM operator or maybe you have problem with phone. If don't you repair it, you test to HW restart. BUT YOU WILL LOST ALL DATA !!!
If you turn off the data connection it will stay off until something in the phone prompts for network access. I usually just refresh my weather page and it fires up and is back online.
However since you hardbooted your phone and still have no luck you might be having other issues. Even more so since you cannot make a call or anything since disabling it. Any new software or flashing done to the phone's rom or radio?
Ok ty all!
My phone is back on.
I don't know how but it works.
Although I still have some problems with my network.

I have a TyTNII phone and after reading extensively through the threads posted, seems to have a unique problem.
My device will show the "E" icon and service provider in the Today screen and everything will be normal.
After connecting to the Active Sync via USB the phone will be normal for a while, but at some stage will disconnect from the GSM network and show no service.
At this stage the "E" icon changed to a "G". I have tried selecting the service provider, finding the network etc, but it keeps telling me to disconnect the data service and try again.
At first I thought it was blue tooth, but it does make no difference. I have loaded all the comm utils I could find and none is showing any active data sessions or connections.
Reset does not work, taking the SIM out and putting it back does not work, not even taking the battery out makes a difference.
All that seems to work is to put the SIM back in another phone and let the phone boot up to get GSM connection. After that I can put the SIM back in the TyTNII and all will be fine - even for days - as long as I do not connect USB to the PC.
Do you have any ideas on what I can do to solve the matter - it is irretating like hell to swap a sim every now and then...
could be wrong but is there a wired connection on your pc/laptop that uses a dial out and not gprs, this could cause it to run a connection on gsm on gprs.
Thank you for the reply - I have checked my pc and have no dialup connections - currently connected to Internet via Ethernet.
I have also checked the phone - during this shutdown period I am able to browse the internet from the phone.
This tells me that I have internet access, just no GSM service - its like the phone is switching the GSM network off, but GPRS and Edge is still working.
Hope that helps
Dunno where you are geographically, but At&t had some major down time last friday or thursday and it seemed again this week on tuesday or so.
Maybe this was effecting you? (boston area) Only time my kaiser does **** like that is when i leave something conflicting open, (mail, or a browser)
good luck
Hi,
I don't know if anyone has heard of this problem or Im just being paranoid, but I installed PocketMax's PhoneAlarm (v 2.13) and was testing some automatic profile switching yesterday, one of which was into flight mode. This worked, but when it came out of flight mode the operator signal strength started to refresh.
ie. GPRS..good signal...HPDSA good signal...HPDSA poor signal...then no signal. The no signal stays like this for some time before the cycle starts again.
Not sure if this could be the weather but it's been clear and cold and checking my sim out on another mobile shows a good steady signal.
The reason why Im pointing to Phone Alarm is that all was well up until this point, before playing with the automatic profile switching into flight mode.
If anyone has any ideas or a setting that can be stabilised in the registry to stop this then Im all ears.
Thanks for you anticipated help or solution.
Apologies if this has been covered already
Not sure if this is relevant or not but:
I noticed that when I upgraded to WM 6.1 my flight mode acted all kinds of strange. Even if I manually put it in flight mode I could sometimes not get it to come out of flight mode and turn the radio back on unless I soft reset the device.
Hi dalavar ,
Thanks for the response. It was fine before and hadn't noticed any problem with signal dropping before upgrading to 6.1, even when looking at flight mode on the comms manager. This suddenly happened after coming out of flight mode using phonealarm Wednesday mid-dayish and has been acting like this since.
I've tried resetting and even reflashing the rom to see if would set things back to normal and still no joy, the same thing happens. The latest thing I tried was a different sim in the phone and again the signal cycles and stays on no service more than another signal. It seems to indicate a phone problem, as I've tried the sim in another phone and the signal is ok.
Im not sure if it could be the weather as it colder than usual where I am and wounder if these phones are prone to not being able to hone in on a signal when ice crystals are in the air deflecting the signal, as a friend suggested, but I think that would affect all phones.
Any further idea's would be gratefully appreciated.
I've discovered, purely by accident, that when I disable the 3g (using duttys 10 button comms manager) the signal comes back and stays, I'm only getting GPRS not HSDPA, at present, which I suppose is something. Under the phone settings I also notices that it is set to GSM and not auto. Something probably I did when trying to find out why this problem occured.
Im trying to set it back to auto (this is what the 3g button does on dutty comms manager), under phone band settings, which was the default setting and this is when the signal problem reoccurs.
Wondering what this auto is looking at?
Where the settings are for it to look at so if it looking for something else I can change it back.
Anyone have any ideas?
Just an update.
This seems a common problem amongst some uk 3G networks, I found forums where Orange and T-Mobile customers had suffered the same problem. Months where 3G working fine then 'Cillit Bang' and the 3G's gone!
It could be the sim has become faulty (rare, but not unknown)
It could, in fact, be that the signal is bad in the recent cold snap here in the UK, which I hoping is the case and when the weather warms up I can test this theory and set 3G back to auto.
Update.
This morning it was still not wokring on auti, at around 11:30 I tried again to turn auto on and now the phone os working again with 3G enabled, but it's only coming up with GPRS.
Not sure if it was the weather as now we are at 9 degress rather zero or in the low minus, and it did appear to come back when the temp increased or could be the network provider has been playing with the transmitters.
Now just awaiting HSDPA to come back.
Still not working correctly. Again it drops signal unless I switch back to GSM. Getting this diagnosed.
Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.
I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.
Bump :x
Anyone have a solution?
Hi XDA, I bought a Z3 Compact a few days ago, and yesterday this weird bug occured for the first time. The data is simply turned off suddenly when I check my phone, and nothing I do will turn it back on.. Toggling mobile data back and forth, searching for networks and clicking different ones, downloading internet settings again, airplane mode on/off etc. - nothing works except rebooting the phone, and then the data works again until next time it messes up. It did it again last night.
I googled the issue, and it seems some S4 users have had same problem with Android 4.4.2? Link to the issue is found here http://support.t-mobile.com/thread/70532
Apparently they report that you cant make calls either when this bug occurs, even when the phone says it has bars, however I havent tested regular calling. I will next time my device bugs out.
Has anyone experienced something similar and/or is there any way to fix it?
I had the same issue but only when Stamina mode was enabled. After a few hours I would lose mobile data and only a reboot would restore it. I cleared data for Eco Mode Controller, rebooted and the problem hasn't reoccurred since. Not sure if this helps or not.

I don't have it enabled, but I will definitely try clearing data for eco mode controller.
Also, I figured out that I can still make calls even when the data doesn't work. So it is not the same issue that is described in the link.
I think you have the same issue as described in this link? https://talk.sonymobile.com/t5/Xper...sappearing-in-Stamina-mode/m-p/845155#U845155
I have had stamina mode on however, so I will try it anyway.
I believe I had the same issue as you: cell signal dying after a while, but more often when cell reception was likely to be cut off (e.g. poor service areas or stamina mode). I'm also on T-Mobile in the US.
You can try the troubleshooting steps I took in this post, but what ultimately ended up working for me was a nano-SIM swap.
If you try all of the above and still haven't managed to fix it, I would suggest a phone swap.
Edit: typo

But if the sim card was the problem, I wouldnt be able to make calls right? I mean, there must be a connection since I can call.
Also, the phone doesn't give me a notification with "No sim card" or something similar..
But then again, weird errors can happen.. I will order a new sim card if the problem persists and I am unable to find a solution

You might be right. My issue was signal, then no signal. I never got a "no SIM card" message, however.
Best of luck!
I am now getting this issue without using Stamina mode. I am currently sat at work with no data, same thing happened yesterday. It worked fine this morning but at some point it has gone and only a reboot will get it back. I am missing important notifications because of this.
It seems to happen when I move around the building and the signal goes weak. The About -> Status page currently shows:
Signal strength: -79 dBm 17 asu
Mobile network type: HSPA
Service state: Voice: In service - Data: In service
Mobile network state: Disconnected
This is so frustrating.
---------- Post added at 12:43 PM ---------- Previous post was at 12:36 PM ----------
Just rebooted, data is back and now I see this in About -> Status:
Signal strength: -75 dBm 20 asu
Mobile network type: HSPA
Service state: Voice: In service - Data: In service
Mobile network state: Connected
Time to seek a refund.
I never got this issue fixed, even after repairing the device using PC Companion so I've sent it back to Clove for a refund. I think Bluetooth may have something to do with it though: I use BT in the car and have a Fitbit connected. I spent a day with BT disabled and the issue did not occur. I then went for a run with BT headphones connected and when I got back I had no mobile data again.
So goodbye Xperia Z3 Compact.
Anyone managed to fix it?
Hi!
I have the same issue. I use BT in my car too, but I think I lose it event without BT sometimes..
Anyone managed to fix it?
Just wanted to pitch in that I have the same problem (Z3 here).
I was going to return the phone but reading that the new lollipop update will arrive next week I think I'll hold out and see if that update won't fix it.
/Edit
See if Paul Wheeler3's post here works for you , I cant paste the link since I have posted 10 times here... but google with his name, and search for Xperia Z3 Losing Data Connection. should be one of the top hits.

COPIED and PASTED for your ENJOYMENT:
I thought I’d share a quick tweak that applies to most of Sony’s Xperia Android phones. If you’re on the Three network and travel around a fair bit you’ll notice that occasionally you’ll lose the data connection and it won’t always come back until you reboot the phone. Very annoying.
This happens because Three still have some 2G roaming agreements in place for areas they don’t have coverage. That doesn’t include data roaming however and a lot of devices (including the iPhone still) have trouble with this.
The way to fix this is to set the ‘Network Mode’ to ‘4G/WCMA’. Annoyingly you can’t set this in the ‘Mobile Network Settings’ section, you’ll need to go into hidden service menu to get to the setting. From the dialler, type this:
*#*#SERVICE#*#*
'Service' is typed as you would on a T9 predictive text keyboard, so thats one key press per letter.
Once your into the service menu, choose ‘Network Mode’ and then within this menu choose ‘LTE_WCDMA’.
You’ll see the radio stack reboot (so you’ll lose your connection while it does this).
No longer shall you experience the annoying ‘data never comes back’ issue.
It goes without saying that changing this setting is at your own risk.
You should manually set your network to WCDMA/GSM first. Then do as suggested above.
The problem is that the mode will automatically fall back to whatever is set in the UI if you even load the Mobile Networks control (by simply selecting the menu item in settings). If you leave it stock, then going into mobile networks will cause it to "fallback" into the failure mode. But if you manually set it to WCDMA/GSM then going in to Mobile Networks will only cause it to fallback into HSPA+, which isn't bad.
I'm getting this exact same issue but on my galaxy s5 only a reboot will resolve it I wonder if it is also in relation to 2G networks. I am on EE and the just recently sold to BT could be that their infrastructure now includes 2G coverage with no data for some places? Soon as I reboot back on 4G. Looked in settings and annoyingly only auto ones are 2G/3G/4G and 2G/3G there is no 3G/4G auto connection type guess I need to find a Samsung secret menu?

I am on a tmobile z3 and it says N/A no matter which mode I put it on in settings and then going to that secret menu. Please help. I'm on stock android 5.0.2 lollipop. Thanks!
still have the same bug with my Z3 compact, Android 6.0.1 and it is very resistent, even secure mode without 3rd party Apps, new SIM Card and new mobile phone (but with restored Sony Backup) helped. Vodafone germany and Sony Customer Care are idealess.
Last try will bei leaving SD card out and a reset with Sony companion without restoring backup
When I drive to work my phone at some point drops connection to tmobile network then goes to searching and stays there until I turn airplane mode on and off, then it will reconnect to network. It's annoying to have to do the airplane mode thing to get it to reconnect to the network. I have checked the network settings and its set to auto connect or auto register, so I am not sure what the problem is. Anyone have this issue? I am sorta new to root and I am pretty sure I didnt unistall anything necessary, just normal bloatware..
Nevermind, called customer service, eventually got someone techinically savy, I got a bad sim card that wont switch towers automatically. Going to the store to pick up new sim after work.
