Fuze doesn't receive calls

I've been having a problem with my Fuze randomly not being able to receive text messages or calls.
Sometimes when people call, they say it rings twice and goes to voice mail. All the while, I never hear anything or get a notification. This happened once after I texted someone to call me when they get a chance. They tried 3 times and then texted me back to say that they were getting sent to voice mail. I didn't get notification for either until after I called this person myself 20 minutes later. Right when the call connected, I got notification of a new text message.
Another time, somebody was calling me for 3 days. I didn't know he was trying to reach me until he finally left a voice mail and I got the notification for that (no missed call notifications).
I called AT&T and their tech support did some tests (called my phone) but since it isn't reproducible 100% of the time, they couldn't offer any explanation.
This isn't a bars/signal issue either as this is occurring in the same spot where my Tilt would always receive calls fine.
Has anyone else seen this?

I had the exact same problem with my Sprint Touch Pro & ended my contract early & switched to at&t. Hopefully it's not a fundamental hardware problem.

Did you get a Fuze when you switched? Has that worked better for you? I'm still within my 30 days, so I'm debating exchanging it or just returning it and giving up.

I'm having the same problem. I did a quick search and found this;
This AT&T Forum Post
I tried the workaround and haven't had a chance to really test it yet though. I also noticed a few other settings in there that might have accounted for it.
One selection inside the phone settings had to do with whether calls went to voicemail when you're "Unavailable" or "Busy." I'm not familiar enough with the phone to know when it might tag me as either one so I unchecked both and I'm going to recreate my missed calls this morning.
Someone called after the phone had been sitting on my desk all night so I thought maybe it thought I was "Unavailable" due to inactivity (I dunno, I'm winging it) so I'm letting it idle for a few hours and getting a call later to see what happens.
Incidentally I have the exact same problem, no call coming in, but then I get the voicemail message after I try calling someone.

Unless I'm misunderstanding your point, "Unavailable" just means that your phone is switched off or out of signal, and "Busy" means you are already in a call. It's nothing to do with the behaviour or features of the phone.
Cheers,
Steve.

Yeah, I'm wondering if the phone is becoming "Unavailable" for some other reason than me being out of range. I have full bars in the house and that's where this all happened.
I've noticed, too, that I didn't get any email (I have it set to check every hour, even hit send/receive after someone told me they sent me something and it still didn't find it until I sent a second email to myself from another address)
Again, I don't know much about phones but it almost seems like the phone has bars but drops off the network for accepting calls/messages until you do something to activate the system again... or something. I dunno, just speculating.

Last week I went in and exchanged my Fuze for a new one since it was still within the 30 days. Up until tonight, I thought the problem was fixed. I was chatting with my wife over IM and she told me that she tried to call but that it just went to voicemail. I asked her to call back and leave a voicemail to see if it would notify me. I also asked her to send me a text. I didn't get notification for either. I checked my data connection by starting up Opera and going to a few sites. So I know that I had a verifiable connection to the network. I called my voicemail and checked the message I knew that she had left. Only after I made the call did I get notifications for the text messages I had missed. I never got any notification for the voicemail or missed calls.
Unfortunately, it seems this is a problem that isn't related to individual hardware as this is my 2nd phone with the same problem. I've also replaced my SIM card since a salesperson at an AT&T store suggested that it might help. I'm running the stock AT&T ROM minus the bloat, so it's not a custom ROM issue either. At this point, I'm not sure what I should do.
The only other thing I can think of that makes me unique is that I currently reside in Washington state but my number is one that I had ported from California. Is there anything about you're (skyau) situation that makes you unique?

Well the same thing happened again tonight. I received text messages 10 minutes late and I didn't get a voicemail notification until I initiated a call. As much as this sucks, I'm hoping it will stay this consistent so that I can have tech support replicate the problem and then try and fix it.

You may have a problem with your phone number. I'd try changing it.

Have you had experience with a problem like this? Is the phone number really the issue?
If that's what the problem actually is, I'm willing to get a new number. But I don't want to change it just to check and see if that fixes it.

same problem! Really pissing me off I just lost a important job because of this issue a few moments ago! Is everyone running a stock rom? I tested a few, now back to stock no apps nothing trying to find this gremlin WTF!

I'm running stock ROM without the bloat.
I exchanged my Fuze (I'm now on my 3rd) on Saturday and changed my phone number yesterday. I'm waiting to see if the issue happens again. If it does, I'll probably do stock ROM, all the bloat, no apps. If there are still problems, I'll probably try different ROMs.
I was able to get AT&T tech support on the line when the problem was occurring luckily. We went through his battery of tests and he verified that there was a problem. It would seem that the phone forgets/loses it's connection to the towers/network. Notifications (calls, texts, voicemails) aren't received until after the phone remembers/reconnects to the network. It remembers/reconnects when you initiate a call or send a text (essentially require the phone to use the network).
The tech told me that as far as he could tell, it was a hardware issue and that I should exchange my phone. So I'm on number 3 now and hoping for the best. I changed my number because I've been in a different state for 2 years and I had no ties to previous area code. So I figured now was as good a time as any to get a full fresh start (phone/number/SIM).
That sucks about losing the job.

Bump, I just realized a few moments ago that my phone rings once and then it says missed call, i always assumed they called me and then hung up after one ring in case i was in class or i was busy so that i could call them back. this is not the case? Also a few cases a call will drop every now a then... is this due to the radio rom i flashed? typical symptoms of a incompatible radio for a specific location? I'm using the .25.35 blackstone radio in ithaca, ny.

Having the same issue. Phone is asleep, then alerts me to a VM. Missed call doesn't show up in missed call list.
Really pissing me off and I think is responsible for my issues with Slide2Answer somehow.

The only time I have missed calls is because of MSVC. If someone calls and it is private or unknown, it will not ring. If it is somebody in my phone book or who doesn't have a private number, the phone will ring.
So I turned MSVC off and the private callers and the unknown callers will ring in.

it happens to me sometimes as well sometimes the d pad area will flash but i cant answer and it wont appear on screen then it wont say missed call.
sometimes if i try to hit the dial button it will also drop connection and instantly pick it up again
annoying but not a huge problem for me
and of course not on stock rom

I cannot make calls with my G2x

This is my second G2x and both have exhibited the same behavior. It will dial a number, whether from the phonebook or the dialer itself, and the phone application will say that it is dialing. After 30 seconds or so, and no ringing on the other end of the line, the call ends itself.
I usually have to enable Airplane mode, then disable it, to be able to make a call. sometimes I have to go as far as rebooting the phone completely after which it may or may not work. Incoming calls fail as well so I am missing quite a few calls and texts...but thhe emails and other data messages come through.
Oddly, data works perfectly regardless of whether the phone is having problems calling. This happens in 2g as well as 4g. I have manually selected 2g and could not call and had the same trouble in WCDMA only mode. I thought it was related to Wifi calling but enabling that has no effect.
Any ideas? I am trying my other line to see if that SIM card is having trouble. I just have no other ideas at this point.

happened to me today too. I have had the phone since March 20th and I have too reboot to make it work. No idea what could it be.

I used to have this problem frequently on my MT3G. Since someone else is having this problem on a different phone, I would guess that it's something software related.

Alright, it is happening on both of my lines. It might be a program that I installed so I am loading them back on one at a time to see if can determine which it is. I am looking at either Google Voice or Beautiful Widgets as likely culprits at this time but there is not certainty. I have also avoided installing Facebook and Twitter. I am able to make calls right now. I will see if this keeps working for the next few hours...maybe through to my morning coffee. I really hope it is an application, something I can do without, because it would be pretty bad if it is the phone. My girl just ordered one of these as well since she likes mine so much.

Happened to me twice today, first in the AM and then again around 2200 central time. i recently started using setcpu so not sure if thats an issue or not. anyone find the app responsible?

Yes, it has happened to me too, usually after it is in standby or idle, and this is my second phone. But my second phone not happens as often as the first one. Reboot is the only way I can get it to work. I notice that the signal is very weak only 1 or 2 bars.

That is a very good point to mention...that it is almost always directly after bringing the phone out of standby. Mine just did it again.

Same problem here. I don't even know how many calls or txts I've missed since.

Had this issue with my N1 and I always chalked it up to cruddy radio and/or coverage. I've since had it on my g2x once or maybe twice I think (had g2x for 3 days now), but at least after it timed out I was able to try again and the call would go through. With my N1 it would never recover unless I toggled airplane mode or sometimes even needed to reboot.
I hope there are some improvements in this area, because bad radio was my biggest gripe with my N1, and i really want to love this phone!

Call ended right away? Can't make calls

Hello,
I was wondering if anyone is experiencing this weird hang up. When I try to make calls, it automatically ends my call without any rings. I keep trying to call and it keeps ending right after it dials.
I had to restart my phone to finally get it to work. It has happened twice to me now.

Same exact issue here. Rebooting sometimes works, sometimes doesn't. Tried uninstalling Google Voice, same issue. Annoying as heck.

Same issue here, on T-Mobile. I exchanged my original phone because I was having radio issues (phone would not connect to the mobile network), but this problem seems to have carried over. Phone is set to use WiFi calling, I'm wondering if there is a handover issue when I leave my home wireless network.

I'm on T-Mobile as well, in north Dallas area. I do not have mine set to do WiFi calling, as it is guaranteed to drop your call when you leave your house (happens every time to me, so now I don't bother with WiFi calling).
This instant "Call Ended" issue is separate.

Yup, happened to me earlier, i had to turn the phone off for 15 minutes. Im on t-mobile

Solution!
I believe I have figured out how to fix this. Go into Settings, then More..., then make sure Wi-Fi Calling is on, then click on Wi-Fi Calling then make sure you have Cellular preferred selected. After I did this, I was able to make calls with Wi-Fi on or off. Hope this fixes yours too.

Same issue here. Call hangs up right after i hit dial. Tonight even resetting the phone twice didn't solve. Finally after 20 minutes I was able to make a call. So frustrating as I had an important conference call I needed to be on. I ended up texting a few people in the call, and my texts were successfully received, just couldn't call out. So frustrating, but comforting knowing that I am not alone. Think I might return this phone as this is the 5th time this issue has occurred and I've only had the phone for 6 days.

I have same issue. I turned off VoLTE and problem gone. Hope this helps.

Sorry, that is not a fix. I've used that configuration and still ran into the instant call ended problem. Thanks for the suggestion though.

VoLTE (voice over LTE) could actually be the problem - that is a setting that comes pre-enabled and I never disabled it. Makes sense to try disabling it and see if it happens again.
I'll report back in a couple days whether the issue happens again with VoLTE disabled.

Man I really like this phone, but the call ending and camera issue, I had to return it. Damn you sony!

The call ended issue hasn't happened to me since disabling VoLTE. Though I did get a call from my wife when she got off work, which when I swiped to answer, my phone rebooted.. that was fun.

It only happened to me once. Rebooting had no effect, but after turning off LTE everything worked. Makes sense that it would be a VoLTE issue.

you can try fiddling with the network mode settings in the more wireless/network option. the t-mobile rep. got it working again after switching the network preferences from LTE Preferred to GSM. That got calls working again. I believe I switched it back to LTE afterwards and I'm not experiencing any more problems with that error.

Same here. It was totally random as to when and how long it would automatically end calls.
VoLTE settings made no difference. Eventually the problem would return.
I just replaced it at the TMobile store.

Problem Solved!
So, I was having this same problem and reading this forum, I discover that I just need to change the network mode
Go to settings > More... > Mobile Networks > Network Mode
And it probably its marked LTE (only).. Just change it for LTE(preferred)/WCDMA/GSM
I hope it can help you

I have HTC One M7 with cm12.1 and I'm having this issue too!

Several problems with my new S6. Please help.

Hello,
I got an S6 through Verizon. It's unlocked. So I'm using it on Total Wireless. Everything was activated last night and was working great. Then, I wake up this morning to check my phone, and as soon as I lit up the screen ALL of my notifications came through that once. I have it set to always allow notifications on the lock screen, wifi sleep is set to always allow connection even in sleep, and data saver is off. I used to have an Asus Zenfone that would do the same thing if it was connected to a router using IPv6. Are there any fixed or known reasons why the S6 does this?
Secondly, out of nowhere today, my phone stopped sending texts and calls. Data was working on everything EXCEPT Facebook Messenger. So before calling Total Wireless, I tried restarting, power cycling, removing and replacing the SIM, resetting network settings, changing it from Global to LTE/CDMA only, and so much more. I eventually caved and called. The reore had me dial *76 to disable call forwarding, although I never even enabled call forwarding. Would that be the main culprit to the issue that I was experiencing? I mean, randomly not sending texts and calls and saying "searching for service" even though it clearly had full signal of LTE and data was still working sounds pretty odd to me. Any ideas?

SMS Delayed and Calls go Right to Voice Mail

Using the device on T-Mobile. Sometimes I'll just get a voice mail notification - without the phone ever ringing. Tested from a desk phone, and sure enough it goes right to voice mail without ever ringing. If I make a call outbound from the Zenfone 6, it will always work. Then I'm able to receive calls for an unknown amount of time. I can reboot and get calls after the reboot, but they will eventually randomly stop.
SMS also come though delayed by hours. For instance someone sends a SMS my way at 2pm, I'll get it at about 4pm. If I send a SMS out bound, I then instantly get all the inbound ones.
Anyone know if I need to whitelist something in battery optimization? So far the Zenfone isn't really good at being a phone. - great at everything else though.

Check your apn settings I think I had to update the default to whatever BYOD APN settings are for T-mobile see if it helps you

Also had this issue on T-Mobile. If APN settings don't fix it, I'd go to Auto-start Manager in Settings > Battery > PowerMaster and allow your messaging apps to run.
For me, I'd get SMS messages only when my screen was on, and some weren't received from contacts, like it shuts the apps off after not using them.

Same here. I'm about to switch providers because of this. What rom are y'all using? I'm on LineageOS 16. @wreid23 can you post your APN settings?
Tried unoptimizing all the messaging related apps, no effect.

So I found that if I turn off WiFi calls come right through. I don't know what the fix is, but I guess that's my work around.

I've found the same to be true for me. Wi-Fi connection prevents calls from coming in. I can dial out just fine.
This is extremely strange since this phone is not even Wi-Fi calling certified and it's not even a feature. This has been my biggest issue with the phone so far because you never know if you miss a really important call.

I purchased a OnePlus 7T for this reason. Can't use this device anymore after getting flack at work for missing and oncall issue due to the phone not ringing because I left wifi on.

Asus denies the phone could be the problem (despite the phone obviously being the only variable). I replied to that thread anyway, with my experience of similar lost calls on a Moto x4 with Wi-Fi calling enabled. Maybe it'll give some engineer at Asus a push in the right direction...

if any of you are rooted there is an alternative for now to enable volte and vowifi: https://forum.xda-developers.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073

I'm having the issue with T-Mobile 7T Pro, when I got the permanent unlock approval and switched to Mint Mobile sim is when calls went to voice mail, have you found a solution yet? Phone works fine if I use T-Mobile sim, but Mint Mobile sim in the 7T Pro is when the calls go to voice mail and text don't go out, if I put the Mint mobile sim into a Pixel XL all is fine. When I had to quit Mint Mobile becasue of this and go back to T-Mobile on prepaid again, all worked well.

The zenfone 6 is getting volte with the android 11 update so hopefully that fixes this issue
