Voice phone call problems. I can make a receive voice phone calls around my local area (approx. 30 min driving circle), outside of that area, I can not make or receive calls, data and texts work fine. Called Verizon, over an hour on the phone trying many things, settings, sim card removal, refreshing network, checking for call restrictions, nothing worked. Took the phone it to a Verizon store, got a new sim card, same thing, no go. I have a refurbished phone coming from Verizon, but would rather keep my new phone.
Any guesses? Roaming is turned on phone, everything seems good, just no out of area calls. If I try to place a call, all it does is sit there saying "dialing" but I here no sounds. After a bit I get error message "out of service area", and then "call lost". It may have done this from day one, as I do not use this phone much for traveling, as I have a work cell. Any help would be great. Thanks.
Would a screen shot from the app LTE on/off, help someone to see if some radio setting is wrong?
I know one thing that is different from my phone to the other two m8's I have here is under the heading radio band, I only have two choices, usa band, and 1800-1900 band, my wife and daughter's phones have a third choice, 800-900 band. Could this be it? And how do I get the third choice back?
Ok guys, what I found out is that you have to use thunderbolt lte app from the play store. Choose cdma+lte, then choose the other radio band, not the US band. Exit out and you are good to go.
Now every time you reboot the phone, you have to go through it again. I don't know why it doesn't stick. Maybe some one can help

Another thing I see different is, in the list of stuff in the lte on off app, Next to GSM service, my phone says emergency only, and the other phones say GSM service, in service. How do I change it from emergency only to in service?
I have seen similar posts of this issue with the Z3 and Z3C, but I wanted to post my experiences and see if anyone that has this issue has been able to resolve it.
I have an unlocked D6603 that I purchased directly from Sony US. When I received it, I got a new LTE SIM from AT&T, but did not give them the IMEI from the Z3. I activated the SIM and still have my old phone's IMEI listed as the device (LG G3). I inserted the SIM card, downloaded the APN settings, rebooted the phone, and everything was working great.
When I got home from work the next day, my wife said that she had called and sent me text messages that I did not receive. I rebooted the phone and all of her texts (as well as texts from other people) came through. This happens almost every day, and sometimes multiple times in one day. I either have to reboot the phone or change the network settings from LTE to WCDMA for the texts to come through.
One thing just noticed while making an incoming call.. My Z3 has full LTE signal, but when the call is coming in, it immediately switches to HSPA, and when the call is disconnected, it immediately switches back to LTE. Not sure if that's normal behavior or not, but figured I would include it in this post.
Same issues with AT&T. Intermittent calls and texts. It's thanks to AT&T's archaic verification system. Because you don't have a bloated AT&T issued device, you need to keep your old (AT&T issued device) IMEI to be able to get LTE signal for data. If you give them your current Z3 IMEI, you will always receive your texts and calls on time but you will not be able to get LTE because your IMEI is not registered in their database. It's a classic case of a carrier advertising "bring your own devices to our network but we won't load your IMEI so you can access the services you actually pay for", pathetic. T-mobile and Verizon actually offer the device but AT&T won't. Also, AT&T does not offer voice over LTE so your calls will always be 3G (H or H+) when connected and when disconnected your phone will go back to LTE for data. You have two choices with the extortion king, AT&T. Update IMEI and get all calls and texts in a timely matter while forfeiting LTE or leaving your old IMEI and get LTE but miss calls and texts. Ridiculous.
My situation is exactly like the op except i dont miss calls and recieve all my text, so something must not be right, have u tried flashing a differnt ftf?
Multiple, doesn't change anything.
Has anyone tried to use a Z3 IMEI in the last month? I know that when it first came out, it was an unrecognized device for purposes of LTE, but at some point that will change. For example, I am using a Z2's IMEI right now, and that certainly is not an AT&T device.

I changed the IMEI on my AT&T account to match my Z3's IMEI, since I would prefer to receive all of my calls and texts over having LTE. After making the change and rebooting my Z3, I still had an LTE connection and I did not experience the missed calls/texts for a few days. Yesterday, I did not receive any texts or calls so I rebooted the Z3 and texts started coming through. So it appears that using the Z3's IMEI is still preventing calls and texts from arriving.

After adding the Z3's IMEI, it is still showing as an unknown device with AT&T, yet it does get an LTE connection.

I just picked up a Z3 straight from a Sony store last week, stopped by an AT&T store first to get a nano sim which they handed me with no question asked but I didn't activate right away as I still had my ion on....
Once back home inserted the nano sim in the Z3 called AT&T to activate the sim, they sent me a text to verify my account and the settings were downloaded to the phone, they asked me if it was a new phone, just told them no just a new sim in my old phone...right away I noticed that I didn't have LTE at all, so went into the APN setting which were a bit different that what I had in the xperia ion, deleted the APN that was downloaded by AT&T to my phone and entered the ion settings manually into the Z3 and right away LTE was back....not a single problem receiving calls/texts and LTE on full time since then...
APN settings (the difference is in the name of the APN from what was downloaded by AT&T if I recall correctly)

The same issue is affecting me too. I also have the D6603 on AT&T network. Don't bother asking AT&T for help, they will say nothing is wrong w/ their network (which I think is technically correct). This sucks because I was motivated by their bring your own device promotion only to be disappointed that they can't help resolve this issue.
Anyway, turning LTE off made the calls and texts more timely for me. So the easy workaround is to add the LTE toggle quick setting button so you don't need to click a few places to get into settings > more... > mobile network setting > network mode > to turn off LTE. This should default you to WCDMA/GSM when LTE is off by the way. I think the speed is somewhere between 3G and definitely not as fast as LTE, but not unbearable either.
This is still a pain in the butt given that we freaking PAY for LTE, but it's a simple work around (for now at least...)

Did you try setting your apn manually?
Delete whatever was downloaded by AT&T and enter the one I posted...I don't have a single problem since

I did try your APN settings, which seemed to work at first, but the issue came back after a day or two.
I contacted Sony about it and they are placing the blame on AT&T. They also had me do a software repair using the Sony PC Companion software. I'll have to test it for a day or two to see if I continue to have problems or not.

still receiving calls and texts just fine but can't answer anymore as I have a different problem now...the phone took a dive from a cliff (literally)
First time I drop and break a phone but also first that I buy insurance, took the" protection plus" when I was at the Sony store, kinda hesitated at first but went for it finally, glad I did now, getting a new one mailed and waiting for it to arrive...
My issue was fixed
I had the same problem for the longest time with all official roms and Slipsystem's. I installed the unofficial CM 12 and the problem disappeared. It is something in the official stuff that messes with it.
I'm on att and don't have this issue at all. Store used a s5 imei when i switched
I have to disagree with some of the comments above. I'm on a D6603 in Texas purchased from the Sony online store several months ago. Had to go to a store to get the new sim card anyway and the salesman registered the phone using the IMEI off the box. The Z3 was added as a new phone on the account (I wanted to take my time moving stuff plus I intended to port my old number to Google Voice anyway). I did the setting option to download the APN myself a few minutes later. The Z3 shows as unknown model on ATT online but LTE data works fine and I've had no problems receiving/making calls or messages. So, using the z3's real IMEI is NOT the problem. Perhaps the problem is some setting that doesn't get reset properly when switching an existing phone whereas adding it as a new line avoided that?
@svnyster @augie7107 @pbsteebs @nirvanayoda have you found a solution to this problem?
here's my experience.
1. I have a straight talk sim card (it uses ATT network) and I experience the same problem.
2. My Xperia Z3 D6603 has LTE coverage, but after a while - even with signal at 2/3 bars - it doesn't receive calls or texts until I restart it, switch airplane mode on/off, or toggle LTE/3G.
3. I know for sure this is not related to the rom I'm using: the phone was in stock conditions (kitkat 4.4), then I rooted and installed a debloated stock lollipop rom... still the same problem.
4. I also know that this is not a sim card issue: we have 2 Xperia Z3 phone (one is my wife's). If I swap my sim card in her phone I have no problem, and call and sms get through. So only one of our Z3's is affected by this problem.
5. Finally, the only way I found to work around this was to switch to WCDMA (preferred)/GSM (instead of LTE preferred/WCDMA/GSM). In this case i receive all calls and sms but I have to give up LTE.....
Any thoughts?
Thanks a lot for your help!

I actually ended up switching devices, because I was unable to do my daily work without consistent LTE, and I got tired to switching between LTE and WCDMA.
Everything I read from AT&T shows that the LTE bands they use are 2, 4, 5, and 17, which the D6603 has all of those bands. However, my new device (Samsung Galaxy Note 4) also includes LTE Band 12, which the D6603 does not support. I know that Band 12 is used by T-Mobile, but if AT&T is using this band in certain areas, that could possibly be part of the explanation of why we're having this issue.
Thanks @svnyster!
I also don't think that switching between LTE and WCDMA is acceptable.
But what confuses me is that we have 2 Z3s and only one of them has this problem...
Any idea if unlocking all bands as suggested here would help?

Thanks again.
Pretty sure it has something to do with how AT&T recognizes your IMEI. Check your account and see what icon shows for both devices. If they are different, that's the culprit. I can't get calls and messages with LTE enabled on my Z3. Fine with 3G. My solution was to leave LTE off until I needed it to stream outside of Wi-Fi. AT&T recognizes my IMEI as a flip phone. I have a HTC M9 as well, unbranded edition, and AT&T recognizes the IMEI as a M9 and calls and messages come through immediately even though LTE is switched on.
i've resorted to leaving LTE off and using the H+, which someone explained is sort of like 3.5G but not quite 4G. At times I'll turn LTE on when I want to watch a video and am unable to connect to wi-fi. Sometimes I'll forget to turn LTE off, and find out later friends were trying to reach me but couldn't. As a result, for me, leaving it off is better (so I can be reached for clients or emergencies).
Still, I realize this is unacceptable, but AT&T does not support this phone (or sell it), so at the end of the day, it's my problem for wanting this phone in the first place. Don't get me wrong, I still like it a lot, but this issue and others are becoming a headache that Sony and AT&T could've gotten right from the get go.
Also, I did upgrade the Z3 to Lollipop. I've noticed the battery draining a bit quicker. Instead of having ~50% by end of day, I'm not at 25% levels. Not quite dead, but I still feel the urge to charge mid day when before I didn't have that urge.
Still, I like being able to move (some of) my apps now to the SD card, freeing up the barely 16 GBs on the phone.
Recently purchased the Xperia Z5 (E6653) and I am having some serious issues with calls on T-Mobile USA.
Calls don't dial out (or it takes multiple tries) and calls won't come in when the phone is connected to 4g (LTE); they go straight to Voicemail. I missed about 12 phone calls yesterday - just getting voicemail after vaoicemail till I realized something was wrong on my side. If I toggle off the LTE it drops to Edge (no HSPA+) and calls come in fast and outgoing calls are made with no problem.
I tried to reset the phone, then repair the software with the Sony Companion app. Still same issue. Looked online for the APN settings. Tried various ones. Re-downloaded the Internet/MMS via the phone itself. Same issue. Tried my wife's sim and it was still doing the same. I have a spare 5s and it worked fine both incoming and outgoing calls. So, it doesn't seem like its the sim card.
I have Rev 2 of this phone so I am not sure if that is anything to be concerned about. Am I missing something...any help on this would be appreciated.
Thanks.
Maybe flash a T-mobile firmware with flashtool?
Or Flash 209 firmware meant for usa?
Or wait for someone here that use this phone on T-mobile.
Are you on band 12 LTE by chance
No, it said band 2 with LTE Discovery. I am on the verge of sending it back. Swap it for another one. Let's see.
From what I have gathered/read - it should really be straight forward. Pop in sim, load Internet settings, and it should work on T-Mobile. The APN settings are correct.
Doesn't makes sense for it to completely not work on 4g and go to 2G (Edge) while skipping 3g. I'm wondering if the baseband might just be wonky. I just see this as causing more problems down the road which I don't want from a $520 device.
Any advice is welcome because I am ordering the same phone again. Lemons are always possible.
Could it be possible because I live a relatively rural area (East TN) and the phone does not support AWS? Since it doesn't support T-Mobile VoLTE and doesn't have AWS it is defaulting to 2G? Is this an issue in all areas or just rural? Apparently the E6683 variant doesn't have this problem as it supports AWS.
Check this http://www.xperiablog.net/2015/10/07/usa-buyers-guide-sony-xperia-z5/
That means ur phone should work fine with T-mobile,maybe go and get a replacement from where you bought it.
I recently bought an unlocked Google Pixel through Google Store. I use Straight Talk's ATT service and had been using it great (i.e. 4G LTE for data and no problem receiving or placing phone calls) on my old phone, a Moto X 2013. The same SIM card does not work properly in my Google Pixel. I've tried using the APN setttings on Straight Talk's website, I've used settings suggested elsewhere on the internet, and I've used the recommended settings that Straight Talk customer support supplied. Nothing works. Sometimes my phone will receive 4G LTE data, but most of the time it does not. I cannot place phone calls either. My phone shows full service bars with a 4G LTE indicator. However, when I try to dial a phone number, the service indicator kicks down to an H (I'm assuming for 3G speeds) and the call does not go through. When I put the same SIM card back into my old phone, both data and phone calls work. Please help! I have no idea what's wrong. I really like the device, but obviously not having data or cellular service is a dealbreaker. PS When I call Google's support, they tell me it must be an issue with Straight Talk and to call them. Not very helpful.

More than likely it is an issue with straight talk. ATT (which I'm on) usually needs to add your phone to their system. I.e. Registering the imei on their network. I would definitely suggest talking to straight talks customer care and make sure you don't need something like a new sim card or to have the phone provisioned to their network. Also your signal dropping from lte to H is normal as ATT doesn't have voice over lte. Which leads me to believe the phone is doing what it's supposed to but the network is not allowing the call to be placed. Same would go for data over their network.
Very frustrated with Unlocked (USA) S22 Ultra. Somewhat frequently but intermittently my phone is unable to make a call. When I try to make the call it just ends immediately - and of note this is in full cellular service (4g or 5G) and also even if WiFi is on and the call is being attempted on WiFi calling. So it's not just a cellular network problem. The problem is reminiscent of back in the day when I would flash a custom ROM and the call features or CSC was messed up.
I believe a similar issue is that often I will get a text from my daughter (who the heck knows how many business calls I missed) - she says that she has tried to call all day and the call just ends immediately and won't ring through to me.
Looks like there are many complaints out there on the internet -- I am looking for a fix hopefully form someone int his community. I wonder if flashing ATT firmware on my unlocked phone would help??
Another problem is that sometimes (definitely intermittently) I am unable to activate the Speakerphone. Pushing the button highlights the Speakerphone indicator BUT the sound is still through the headset - not the speakerphone. Thoughts?
are you on June update? The latest june update seems to have fixed some of the GSM issue so maybe that would resolve your problem.

Never ever had this problem (ATT - locked, 12/512 SD). if nothing else you may want to try to take to ATT for re-provisioning (I assume ATT may be who you are trying to use)

West Virginia explains a lot! I am in South Carolina now but grew up in Pittsburgh so I drive thru West Virginia alot on 79 and not surprised about cell reception.
I've had this happen a few times with an Unlocked version on ATT. I'll try to make a call and it will just immediately end. A reboot fixes it, but if someone was trying to call me I would have no idea.
Have you tried clearing the dialers cache and data?
What about a third party app like googles dialer?
I had the same issue on my s21 ultra and went thru various fixed ( reprovision, changed sim, manufacture reset ..etc). I bought unlocked S22 ultra direct from Samsung and same issue. I have my work # on using physical sim and personal # esim. "when I try to make the call it just ends immediately - and of note this is in full cellular service (4g or 5G).." same issue around 10 times in the last 6 months. It happened on both physical sim and esim. The person who called either number went to voicemail and texting was fine. When I tried to call used either number and it will end right away. when it happened I would reboot and wipe cache partition. I haven't received June update yet and hopefully, that fixes it. I am also unable to send MMS on secondary # but SMS is fine.
