I've got a rooted HTC One on T-Mobile that has worked fine for a couple months. Last week I got a SIM card error a few times and the cell connection was lost until I rebooted, at which point the SIM card error went away and the cell connection (voice and data) worked again.
As of yesterday, my cell connection is not working at all, no bars of service. I do not have a SIM card error displaying in my status bar either. Everything looks fine, just no cell service. It's not a network problem; my wife's phone works fine.
I've tried checking my mobile data settings and pulling and re-inserting my SIM card, but the problem still exists.
Fortunately WiFi works fine so I can still make calls when I have a connection, but obviously this is not sustainable. So... What do I do?
I'm rooted but running the stock ROM. Would it be worth it to flash and wipe? Really seems like a hardware issue to me. Do I have to contact HTC directly about warranty repair/replacement? How long does that process take and is my being rooted going to cause an issue?
Sad

Get a sim card replacement and try that
Suddenly yesterday I started to have problem making call only when 4g is active. The strange think is that I can send and receive sms, surf the web with the 4g connection but cant't make or receive calls. The phone get locked in waiting and after I click close call the phone application seems to get blocked and unresponsive.
My operator says there is no network problem.
If I switch to decks and gsm mode only, the problems vanish.
What I can do? I'm stock with android 4.4.3
My new xperia z3 compact (D5803) receives text messages and calls very intermittently. I'm on AT&T US, stock firmware.
- If I am using the phone (or have very recently used the phone, say within 30 seconds) then most calls and text messages come through fine (though not always).
- If I leave the phone alone for more than a few minutes, text messages or calls almost never come through - though occasionally I get a text message many hours after it was sent.
- If someone leaves a voicemail (because I didn't answer the phone, because the phone didn't ring!), I don't get a notification until I open the voicemail app and manually sync.
- I can make a phone call or send a text message with no problems (texts arrive immediately).
I don't have any of these problems when I put my SIM back into my HTC One M8.
I've tried the following to fix this:
- I went to the AT&T store and had them give me a new nano SIM. It made no difference; same issues.
- I factory reset my phone. It made no difference; same issues.
- I updated to the US version of the firmware. It made no difference; same issues.
- I put the SIM into a second, until that point unused, xperia z3. It made no difference; same issues.
Given that I have exactly the same issues after changing both the SIM and the phone, I can only think it must be some kind of compatibility issue with using AT&T on this phone - except I see that many other users of this forum are on AT&T and aren't having the same problems.
I do notice that I don't have the best signal in my house (usually 1-2 bars) so I'm wondering if maybe that could be related? As I say though, my HTC One works fine, as do all of the other AT&T phones in my house.
I think my next step will be to go and buy a T-Mobile prepaid SIM, just to see if that works, but does anyone have any thoughts or suggestions? All in all this is getting pretty frustrating, because I LOVE the phone, but right now it's unusable for me.
I would suggest reading this thread below. It should give you some tips on how to resolve your issue.
http://forum.xda-developers.com/z3-compact/help/att-apn-settings-lte-t2888644
Thank you for trying to help!
I probably should have added that link as one of the things I had already tried. To be specific, my APN settings are:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http: //mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
---------------------------------
I'm beginning to think it *must* be a signal issue, even though all the other phones in my house are fine. I have the "Advanced Signal Status" app installed, but I'm not sure what I should be looking for to see if there's anything fishy
Don't forget to download the Internet and MMS settings for your phone. You go into Settings > Wireless & Networks > More > Internet settings and download settings for Internet and MMS
Thanks again for the suggestions.
Sadly, it's still not working. I'm pretty sure I had already downloaded those settings, but I did it again anyway (seems you can just download over and over). I even reset the phone after that just to be sure, but the problem persists.
I have the same issue and I live in Sweden....
Im having the same issues. I restart the device and then come all the missed calls and missed txt messages.. i really hope theres a easy fix to this soon.
So, I switched my SIM from AT&T to T-Mobile and it fixed my issues. It seems that the either the poor AT&T reception in my house or some other strange incompatibility between the phone and AT&T was the problem.
Either way there's obviously some kind of issue with this phone - my guess is that when connectivity with the network is poor, the phone maybe times-out and gives up. Perhaps Sony will fix this with a firmware update at some point. In the mean time I would suggest that other folks having this issue maybe go to a part of town where they know reception is very good and see if the problems happen there.
So after 2 days of of testing, a new nano sim card and several phone calls to ATT I found temporary fix. Change your Network mode to WCDMA (preffered)/GSM. While this wont give you LTE it will prevent the missed phone calls and txt messages and at least you have HSPA+ . The problem is the LTE connection to ATT. The connection either drops and or prevents phone calls /texts from coming through the lower HSPA + or 2g bands... Not sure why this is. Hoping that when the Sony Store models start shipping on Nov 2nd they have the same issue and Sony will send out an update to fix the connection issue.
I'm on the US ATT network with the same problem as well. After trouble shooting I have come to agree with you. I'm really hoping Sony sends out an update.
Is this a problem on Tmobile USA with Z3 Compact also?
same issues!
I have two Z3 compacts (US version purchased direct from Sony) on my family plan with the same issues of not receiving SMS or calls when connected to wi-fi, and occasionally cannot receive SMS or calls when not connected to wi-fi either. I am always able to send texts and calls, and MMS/LTE always work (I am usually e-mailed when my phone isn't working and I get that right away). Whenever the phones aren't receiving calls, it rings once and goes to voicemail, which tips us off that the phones aren't working.
If you are also getting this problem, please get on AT&T chat and ask them to escalate/forward to their manager. We've got to get their attention. Additionally, I was told that "Okay so since the phone is unlocked our service is not guaranteed to work at full capacity, also I can not submit a case due to it is not an at&t phone. "
Yep - Same problem over here. AT&T in Northeast USA.
AT&T tried everything they could (resettings connection, etc) but again also said that it isn't guaranteed to work because it's an unlocked device.
I'm doing a system repair on the phone from the sony desktop application. Hoping it will fix, but not hopeful. Now sony says they want to have my phone in for testing. :/
I'm hoping they realize soon that this is a bug, and not a case of a broken phone.
Same problem here on cricket (AT&T) in Houston. Just disabled LTE. We'll see if that fixes it like it did for the other guy. Sony needs to get on this.

Not working MMS
Yep I have tried all of the above solutions and nothing is working. Changed APN multiple times, factory reset, switched SIM, called att, went into the store.
Like above, ATT came to the conclusion that unlocked phones are sometimes not compatible with their service and there's only so much trouble shooting they can do.
I have ATT in san francisco, and it's looking like I'm going to return the Xperia z3c. Shame it's a great phone besides the MMS issue.

Confirmed that this worked on my wife's z3c. She wont miss the LTE anyway since she is always near wifi and when she isn't 3G is definitely good enough. We streamed spotify for an hour today on country roads on her phone on 3G. No issues.

sorry to hear you guys are having such issues...
My z3 compact on att works flawlessly. I swapped my nano sim from a iphone 6 i was trying out straight into this.
Att did mention something about some settings they had to flip in the back end when i switched over to a nano sim from the sim i was using in my lg g3. If you guys loose all hope have a buddy with an iphone on att and use his imei and let att configure the sim for that phone then swap the sim into the z3...could work because i know it does for me
Same issues here. I have a new D5803 on Straight Talk (AT&T). I live in the mid Atlantic. It seems I don't receive calls/texts when I have 2 bars or less. Not sure about LTE vs. HSPA. I always have Wifi on so not sure if turning it off would make a difference. THIS IS A HUGE ISSUE! Hopefully a firmware update will save us. Has anyone contacted Sony?

Yes it does make a difference. Turn it off and everything should work.

Thanks for the info, but this isn't a viable solution! I shouldn't have to keep Wifi off to ensure I receive my calls/texts!
Hi,
I rebranded my VTR-L09 to L29 two years ago.
Since then I use the dual SIM functionality nearly every day at work.
SIM1 is my private card, SIM2 is my work card.
Both are in the same network (Vodafone DE) but different providers (SIM1 is 1und1 and SIM2 is Vodafone).
Since some days I'm not able to make calls with SIM1 when SIM2 is inserted.
When I try to make a call while SIM2 is active, the phone app switches automatically to SIM2 without asking.
When I disable SIM2 in Dual SIM settings, I get the message "Mobile network not available" (translated) when I try to make a call.
When SIM2 is removed I can make calls without any issues.
Internet (HSDPA+ and lower, LTE is not available in my contract) and receiving calls is still possible and without any issues even SIM2 is active.
In dual SIM settings the standard SIM for calls setting is disabled, but even if I set it to SIM1 the calls will go over SIM2.
I already called my provider and I will get a new sim card but I doubt that this is the issue.
Does anyone knows this and is there a fix for this?
I'm on C432 B376 by the way, and there's no update available for me, yet.
My phone is also rooted.
A factory reset would be very annoying since it takes extremely long time to back everything up.
Greetings,
Jannomag
I also have rebranded my VTR-L09 into VTR-L29, but I have no dual SIM issues. Build number 376 (C432). What happens if you swap the SIMs?
The same issue, but inverted. The phone switches to my companies sim card automatically.
Is it possible that the network provider block this standby dual sim thingy?
I received my new sim card but it still doesn't work.
A few days ago I installed Google's phone apk as a second phone app for my second sim, because I wanted to seperate my private and companies contact lists. This didn't worked as I expected and I completely removed it and deleted cache and dalvik via TWRP.
Maybe the issue was produced by this, but how do I remove it?
It sounds like a plausible explanation. If that is the case, I am afraid the only thing that will help is a factory reset, unless you figure out what changes were made by the google phone app.
I did a factory reset...took about 5 hours to get everything like it was before.
Even with TB some apps don't work good (WhatsApp for example, needed to reinstall it...but somehow the backup from yesterday was gone, so I got a throwback to last week).
Now I can make calls again as usual. Strange behavior...
It looks that google dialer apk messed something in your phone. good to hear,that all is ok now.
I am also rebranded VTR-L09 to VTR-L29 year ago. I am on C432 B379.
both SIMs are on Vodafone network and everything works as it should (SIM1 - private+data enabled, SIM2 - work+data disabled).
I am on stock firmware, no root, stock dialer. @Jannomag : 5 hours?Really? I made factory reset two months ago (backup trough huawei backup) and it was matte rof 1 hour. Of course i have to sign in to FB,Whatsap,instagram...
Hi,
I use dual sim and one is for phone calls and one for internet connection. When I make a phone call, there is no connection to the internet. Navigation with google maps says that it is offline and no messages or mails are received. When the call ends. The connection is working again. During the call the Mi8 shows 4G for both sim cards.
Is this a configuraton problem?
Hi!
There is not active-active SIM card slots, it means that if you do a phone call with SIM1, SIM2 will be off-line during the call.
Try this, go to settings and in the search bar on top write: unrestricted data
Open the menu, more, show system and find Phone... Enable it and try it again see if this solve your problem.

Try this: set your region to Hong Kong, then reboot your phone. Once it's on, go to the Sim Cards & Mobile Networks option and enable VoLTE on both Sim 1 and Sim 2. Then give it another go.
Hi, thank you for your replies. It works now with VoLTE, but only if the connection is set to SIM1. SIM2 is off during calls.
