No incomming calls while in 3G (UMTS) Network

Hi all together.
I'm interested if someone else can confirm this Problem. Situation:
- HTC Incedible S (brand new )
- Provider: Orange Switzerland
We suddenly recognized, that it's not possible to call this phone . The caller just get's a voice-info that the "The person you have called is temporary not available. Please try later". But the other way round works perfectly, so a call-out FROM the Incredible works fine and everytime.
I did some investigations and discovered the following:
- When forcing to 2G (=GSM) the Problem disappears.
- When forcing to 3G (=UMTS) the Problem reappears - but...
- ... when at the same time "mobile data connection" is active --> Problem away!
So when i'm at my home then the WiFi-Connection automatically get's active and the "mobile data connection" get's offline. And in this situation no calls reach the phone any more. If i manually disable WiFi (and then "mobile data" get's active again): Voila, everything is ok.
Reenabling WiFi - mobile data goes off: No more incomming calls.
Disabling both WiFi and mobile data: Also no incomming calls.
It seems that the incomming-call-signaling is handled in a way that requires an active mobile-data-connection. This seems to be a little bit odd.
Thanks for any ideas or just a confimation that i'm not alone.
Oli
P.S.: Of course i called the providers hotline. But they just said that there is no problem in the net. I should try it a few days later agein. Damn...

Hmm sounds strange....
The only tip I can give currently: goto settings - WiFi & networks - mobile data. And check the mobile data always on.
It's not a real solution, but should fix it for the time being.
But it is strange... Should not happen, maybe there are some problems with there network, so keep trying for the next few days. Otherwise contact them again.

ah! I believe this is something to do with the network provider. Do you live in a place where the network coverage is midiocre? I have the same problem with the iphone 4 (with the bumper )... sometimes even I am not able to make calls... so I have to switch off my 3G! it is indeed odd coz it interupts with the wifi! Did you try doing a master reset?

Thanks for this idea, but this option was already checked. This seems to be the default, so all my tests (as described in the first post) ran under this config (e.g. "mobile-data-always-on" is checked)
Hm. Still hope for any other ideas.

No, it seems to be a pretty good UMTS-coverage. And the mobile-data-download-speed with HSPDA is really fast (1-2 MBit/s). And when i go outdoor the signal-strength (as shown on the phones display) goes up to 4-of-4-bars (100% Signal). And still: incomming calls not working.
So i think the 'physical' Network-Infrastructure is not the problem. It's obviously a netwrok-logic-problem.
Thanks a lot for your help/ideas.

Ok, some new observations.
The problem of "no incomming calls while connected through UMTS" seems to be a local problem of the network-cell/Antenna around my home.
If i'm about 500m away then the problem seems to disappear..
Of course i did not test every Antenna of Orange Switzerland
Another point: I wrote that the problem just occures when i'm booked in in UMTS AND mobile-data is inactive. That's not completly true, as my newest investigations show: The problem is also present if UMTS-mobile-data is enabled.
But it dissapears for some seconds while and shortly after there is mobile-data-traffic.
Example:
- UMTS forced (no GSM), mobile-data enabled, WiFi disabled
- Phone 'idles' some minutes, no background data-transfer
- Here the Phone can not be called
- Now i go into Android-Market, search a 'Big-App' (10-20MB) and start download
- While the download is in Progress the Phone CAN be called
- A few seconds after the download completes, the Phone still CAN be called
- But later - let's say 60 seconds - the Problem re-appears.
So it seems that an active data-transfer is like a 'heartbeat' for the Orange-Cell and the Cell registers the phone as 'online'. But when data-idle the heartbeat is missin.
I will make some more calls to the Orange Hotline

did you solve it. i don't think thats the case certainly not for me as i'm having exactly that issue of no calls while in 3g mode but if i go back to a stock rom its fine. so the reception distance/signal is identical (i.e i haven't moved anywhere) and its fine on one rom and not another so it must be software (in my case)

So, hi together.
As the original poster i can now confirm that the described problem dissapeared.
We had nothing to do - so no change of any settings nor doing any software-updates. It's simply woking again.
So i'm no pretty sure that the problem was just a local one, in exactly out network-cell. No problem of the device.
Nevertheless: Thanks all for yout infos and tipps.

My XT860 weird sudden WiFi issue

Hello everyone, I know I am totally new to the forum but I assure you that before I wrote this, & before I even joined, I’ve been digging into all WiFi-related problems.
Before I post in this great forum I want to say that I owe all the developers here a BIG thanks, not only for development effort, but also for all help and guidance, it is you guys what make this forum and android community amazing! THANK YOU GUYS !!
The post might look long but I thought describing the issue in one brief post would be better in avoiding doing so in the form of many 2-line posts scattered through a 10-page thread.
Although my WiFi issue seems to me more like a hardware malfunction issue, it seems it’s one of its own where some indicators make me doubt it could be related to software too.
Here what the problem is about:
While I was messaging on WhatsApp, my phone suddenly disconnected from home WiFi & wasn’t able to reconnect anymore at all.
I now can only scan for wireless networks; here is how the problem takes place:
- As soon as I connect to a WiFi network, either it being secured or non-secured, the procedure gets stuck for 10-20 seconds at “Obtaining IP address from (Network ABC)”
- WiFi stays on but then shows “disconnected” or “Unsuccessful”, & (Network ABC) disappears from available networks list (unknown networks doesn’t)
- (Network ABC) reappears –> Device tries connecting to it –> Hangs in obtaining IP –> WiFi turns off
- I turn it on –> Device tries connecting to (Network ABC) –> Fails the same way –> WiFi turns off
- I turn it on –> Hangs completely in “Turning On…”, can’t disable or enable or anything, & got to reboot or battery would drain like crazy!
Things I tried (with no good):
- Resetting my WiFi router (other devices can connect to it)
- Connecting to other private & public routers that other devices normally connect to
- Fix WiFi using market applications: FXR WiFi fix and rescue, and Fix My WiFi
- Wiping cache & Wiping/Factory reset using the built in recovery on device
- Restoring a non-safe system recovery img that was created before the problem started
- Using RSDLite to flash the XT860 5.5.1-112 sbf available at sbf.droid-developers.org
- Safestrap: Wiped cache & dalvik cache, Formatted /system, then Wiped/Factory reset
- Connecting WiFi while on other ROMs (in safe system): CM9, MAVROM 4.5, DarkDroid 1.1, & the rooted deodexed 2.3.6 Motoblur.
Other info & symptoms that may help:
- Mobile hotspot not working in the manner of WiFi: As soon as my laptop or another device tries connecting to my XT860 mobile hotspot, the hotspot disappears from network list on my laptop
- The problem started during my first WiFi usage after the enabling of APN mobile network data
- When I switched on WiFi while Mobile Data was enabled, phone showed a successful connection to my home WiFi ! But stayed for a minute or two, then disconnected, then mobile data would hang & wouldn’t get disabled without a reboot
- WhatsApp chooses random tones when a message is received, even after the many flashes I did (this might sound geeky to mention lol, but it all actually started when I was using WhatsApp, which works using radio)
- GSM network and Bluetooth are working fine
So what do you guys think? What is the chance of it being about the drivers or something?
Or is it totally a hardware defect that grants me a replacement especially that it started while on stock?

Given it survived an rsdlite flash I would lean towards hardware. I know people have had issues with rsdlite not flashing properly, you could confirm by using moto-fastboot to flash the device manually. It's a command line utility, I'm not sure how comfortable you are using terminal commands

Thanks, I'll try the moto-fasboot way..
But what if it is really a hardware defect? I once read that rooting voids warranty, I mean with all what I've tried to solve this, would Motorola still provide a replacement?

Fastboot flashing removes the signs of rooting. Same as RSDLite. It's what they would do for a software issue, it pushes the factory software image.
Lots of people in this forum have gotten replacements after having rooted.

[Q] My mobile data disappears until I reboot

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

Temporary dialer disconnection when 4G is on

Good day, guys. I have a problem. After update to 8.1 I have an issue with recieving calls, when some people call me and 4G mode is on (4G network type is enabled in mobile network settings) sometimes they can not dial to me, it seems like my phone is turned off and there is no signal. If I change mobile network mode to 3G, there is no problems. Also when people can't call me, I can make calls to them and there is no problems with connetion and mobile data. (connection level is full).
It looks like there is some energy saving mode of radioband module and It doens't work properly.
So I've changed SIM-card and changed the mobile operator to another, the problem still exists.
In the safety mode, the problem still exists too.
Also factory reset from recovery menu (wipe data) didn't help.
Is there any fix of this problem? I can't redownload the firmware with OST because of error. Thank you a lot.

I have similar problem, did you find out how to solve it?

Wi-Fi Calling disables cell radio?

Starting this morning (5/8/18) whenever my device enables Wi-Fi Calling, my cellular radio shuts down causing me to have no signal once I leave the boundaries of the WiFi. Under normal circumstances your signal should automatically return, but that's not happening in my case. So far the only stopgap measure I've found is to reset the network settings which restores signal as long as I keep the calling feature disabled.
Anyone have a clue? Flashing the KDZ didn't help. Should I send the device in for a repair?
Edit - Reflashed the KDZ and all is well now. I'm starting to think the WiFi Calling app was having issues, despite being set to maintain cell service while connected.
P.S - If a mod would like to delete this thread, feel free.
