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

[Q] Help! Stock HTC Inspire not receiving incoming calls or texts

So about 3 days ago my Inspire randomly stopped receiving incoming calls/texts, callers ring out to voicemail and I have no idea anyone has called. Talked with AT&T tech support and found out there are no problems on their end. Also, incoming calls/texts will be received during outgoing calls I make (apparently the calls are routed differently for call waiting). I've tried deleting apps i've downloaded recently and even a factory data reset, still with no luck. If anyone has any idea what could be causing this problem, I would really appreciate any help you could offer. Thanks!

take out SIM
put back in
try SIM swapping with other phone

I am having same problem, randomly not receiving calls if the caller leaves a VM I generally get it later. sometimes my wife will call me on home phone and tell me my cell is not ringing and if I try to call myself it works about half the time, no idea what is causing this.

Anyone else missing calls?

I'm having a bit of a strange issue. Not sure if it's related to charging or not, but I have missed at least 3 calls with no notifications only to get a voicemail notification. I believe the first two happened on the charger and the third just happened a little while ago definitely on the charger. Most calls seem to come through and my apartment can be a bit of a reception nightmare; however, my signal is always 3G at home to negate that and this wasn't an issue on my old phone. It seems that my device randomly drops onto a 2G not my network occasionally(Bell/Telus don't have 2G gsm towers, only Rogers). Roaming is disabled which would explain why I would miss the call entirely, but every time I check my phone, it's registered on the network it should be with 3-5 bars of signal
I get a lot of phone calls from work so it can be a bit frustrating... Thankfully they always leave a message. Anyone else missing calls?

Are you using a wireless charger? I've heard claims that wireless charging can interfere with signal. I can't confirm it for myself as I very rarely get phone calls, but I certainly haven't received any calls while wireless charging. I don't have voicemail either, so I could be in the same situation and not know it. :silly:

Yes. I am having the same issues of calls not coming through, but only being notified if a voicemail has been left. Though my issue does not just happen when my phone is being charged. I went into USCC and the associate could not replicate it as it occurs randomly. She called tech support and they could not come up with an answer. The associate when on to say it was the callers phones causing the problem and not mine. Yeah, right.

missed calls
I have a galaxy s6 active on AT&T and I'm experiencing the same issues. It has happened while my phone is not on or near any chargers. It also had full reception as I was in the same room as my AT&T microcell. My wife asked if I heard my phone ring, but it didn't when she called. She tried calling it while I was next to her. Her phone dialed and rang, but my phone had no incoming call. I also tried calling her right back, but it would not dial at all. I just purchased the phone and will quickly be taking it back to exchange for something else if I continue missing calls . Has anyone gotten feedback?

It happens to me. Usually when I'm in a building with a metal roof., but not always. It's random.

Me too
Just upgraded my S3 to S6 and I've been nothing but issues with missed calls. I'm usungOtter box case on my phone. My phone could be right next to me in the house or be in the charger and I'd miss the call. It never happened to me...ever in my house.
I haven't called Samsung yet for support. Not sure what they're going to say.

I had the same issue but it is rare. Updated my firmware helps with the signal.

Got a lot of missed calls on XtreStoLite 2.2 (see details at bottom) and sometimes answering calls not working too.
Was on a fresh original firmware before flashing rom.
I just updated to 2.4. Hope is related to Baseband Version. Will report later if still got same issue.

Same story with full LTE signal, wifi calling off. Incoming calls fail to reach my phone most of the time but outbound calls always work.
At my office a majority of my incoming calls do not come in... the people calling me report it "rings" 2 times and goes to my voice mail. The phone does not ring, show any notification a call is inbound, nor does it list the calls in the log.
Voicemail notification and SMS are the same story... I sometimes get a text message 30 minutes after it was sent by the person when the inbound cell stuff decides to start working.
Now if I make an outbound call, inbound calls and sms will arrive no problem for about 30minutes to an hour... but it eventually goes back to missing incoming messages.
I've gone through the agony of customer/tech support, switching on/off VoLTE, Wifi calling, call banning, Do not disturb, etc. but no luck. The phone seems to go into some suspend mode with the tower and nothing can get in .

95% of missed call issues are carrier based. You may want to talk to your carrier about putting in a network ticket or about getting a replacement sim.
That said, OP specifically, try putting your phone in safe mode when charging and see if it continues.

I forgot to mention this is a tmobile-branded device.
I was able to confirm that this is a baseband firmware issue (G920TUVU3D0I1) that incoming calls are missed and texts are substantially delayed after a certain amount of screen-off time. My original device and first replacement had this baseband version and had the same issue on two different sim cards.
The only solution is to get a device with the older baseband version (G920TUVU2COF8) which my second replacement had and has been working trouble-free ever since.

Patch coming to 5.1.1
Rogers just confirmed there is indeed a problem with the latest 5.1.1 causing the SMS and call issues and a fix is coming 11/16. We'll have to see when the other carriers push this out

Tmobile is rolling out G920TUVU3DOJ7 tonight, hope this is the same fix Rogers discussed on their forum

Before i start I'm not saying any of you are involved in any criminality but incase you are worried about your privacy/security in any way shape or form its worth considering what im saying, I'm sure you all know of ed Snowden revelations and you know that L.E. have the capabilities to remotely activate your phones mic. A friend of mine has been in this situation where when in a sensitive situation altough having full signal and in an open space and where not able to recieve any calls as the mic was already being used by some unknown entity. In these situations if my friend tries to make a call it doesn't go through the first try, it doesn't even go to answer service just cuts out. Next time he tries to ring out it goes straight away. Him making the first call cuts them off from listening through his mic. Things have then happened after some of these conversations that would have been impossible without the monitoring .
Again I'm sure none of you are involved in any dodgy dealings but it's worth knowing if your conscious of your privacy.

I can't make any normal call, but full network coverage, and internet 4G normal

Hi,
I have not been using my OP6 because of a strange issue with it since OOS 10.3.9 (maybe since May 2021)
This issue is: I can not make nor receive normal call with any provider. but my network bar is full and my 4G internet is running smoothly.
If I try to make a call, it just show the call screen, no calling tone and no waiting tone and the other phone doesn't ring.
If I try to call my OP6 from other phones, it just doesn't connect, no call tone no waiting tone... My OP6 also doesn't show any incoming call.
I'm sure my sim cards are OK, I have tried to put them in a different phone and they can make normal call.
If my sim card slots were broken, I would not have any coverage and my 4G wouldn't work...
I can receive SMS just fine.
anybody can help me?
thank you

I had the same issue, at the end oneplus said, bring it to a service center while there plenty or forum posts in their forums from technician saying it's the network chip, i got a new phone but will attempt to replace that chip once i got my replacement.
You could try other stuff, full wipe, other roms etc.

Outboud calls ending upon answer

Hello guys, my ZF6 has issues with outbound calls, when I compose a number 2/4 times call ends right away, 1/4 times call ends upon response, 1/4 times (usually after many redials) I can actually talk with whom I was trying to. This is unbearable, but before throwing the phone in the garbage I would like to know if there's something I can try first: could it work if I reset the phone completely? Could it be caused by some apps interference, or messed up setting somewhere? Or is it just plainly a hardware problem and there's no way to fix that? Ofc just tried to switch phone and calls go through flawlessly, so sim card should not be the culprit here. At the same time though I don't seem to have any problems at all with inbound calls or internet connection, so I'm really baffled here.
Please help, thanks!
