Voicecalls not coming through whenever data is on

Guys
Noticed something funny with my Galaxy Nexus. Calls don't seem to be coming through whenever it is transmitting or receiving data on the 3G. I can still make calls no problem.
My previous phone (the N97) would disengage packet connection (a warning comes up) before the call comes through.
I'm still analysis the data but I am hoping that one of you has experience this before and can offer some insight.
I've done the following test:
1. Wifi and 3G on. Some calls come through, some goes to voicemail.
2. Wifi and 3G on - streaming a video from my NAS box - Some calls come through, some goes to voicemail.
3.Disengaged Wifi and 3G on - Some calls come through, some goes to voicemail.
4.Disengaged Wifi and 3G off (2G only) - Calls comes through fine (when I send text I get the volume bug).
5.Disengaged Wifi and Data on but only on 2G - Calls comes through fine.
In all above instances when the 3G/data is on, I make sure I am transmitting (I synch my hotmail account).
So is this normal (this is my first android phone)? Am I the only one or are there others?
Any feedback would be appreciated.
Thanks

Which network?

It's certainly not normal behaviour in Gingerbread and earlier at least (still waiting for my GN to be delivered). Even on 3G calls should be able to come through and then if needed decide to switch down to 2G if it decides it's needed.
Have you confirmed that you can actually make and receive call on 3G currently? Might be something wrong with your plan or your SIM.

I'm still testing but it does appear that whenever it's transmitting on 3G (3G or H in the icon) incoming calls go to voicemail.
I just did another test, in the previous tests I was just calling my voicemail service (901) but I decided to call my house phone and here's the strangest thing.
- With the wifi on and 3G I couldn't make any phone calls (apart from the voicemail), the calls just end. I turned off the wifi, tried making a call it works. Then turned on the wifi on again and I can make calls again. How bizarre.
I'm hoping it's a network issue but I won't know until say about a weeks time (if its a network issue it should have been fix within that period). But my first adventure with Android isn't going very well.

Rang O2 and it sounds like an issue with the network . According to them 3G was affect all over the country recently and still have issues in the London area.
I also put my sim back into my N97 and after numerous attempts was able to replicate the fault So happy.
But the customer support suggested that I should still go and get a replacement sim from the shops tomorrow since mine is quite old. From 2009 but still 3G enabled.
So fingers crossed that its def a network issue and not a fluke that it affected my N97.

How will a new SIM be able to work better? I thought, as long as it has 3G, it's all good?
My SIM is from 2008, I guess, so quite "old", as well...

Does SIM age really matter? I've been using the same SIM card since 2005.

I don't know if the age of the SIM matters, but what I do know is after I replaced my old SIM (AT&T) my data got faster (a few phones ago).
It never hurts to use a new SIM. The manufacturers change every few years (gemalto, etc) and I'd bet that newer is better...

Are u experiencing any issues with network connection?

My s3 randomly loses connection to the network. Today I picked up my phone to make a call and noticed it was not connected to the network and displayed Emergency call only message.
This happened a few times before too. Initially, I thought it could be a buggy sim so I got a brand new sim from telus. But its still does it. Randomly though. Any thoughts guys?

Anyone?

I haven't really noticed any issues, but I'm on AT&T. What ROM/firmware/modem?

I had similar problems till i disabled LTE. It was trying to connect to it all the time plus it was killing battery.

me and my brother have had the issue in dowtown ottawa on rogers. seems fine in my apt in the market but on a patio and at a restaurant it just wouldnt work!! couldnt send texts, or receive, couldnt call, sometimes it showed i had full bars and lte but couldnt do anything. my brother complained about this the day before. i will try disabling lte next time

[Q] Poor Voice/SMS/MMS Reliability with Galaxy Note 2

Below is a thread I opened on Sprint's discussion board as thread #103192. Sorry I can't link as this is my first post. Anyone have any suggestions here at XDA?
Hello, I am a 15 year customer of Sprint. I have been having a great deal of problems with my Samsung Galaxy Note 2 since I purchased it from a Sprint store on the release date of October 25th 2012. I purchased the first box sold at store location #898 located on RT 59 in Naperville, IL.
Please assume all problems below are seen with no third party applications installed that may potentially interfere with quality of service. Wireless settings are set to use Sprint's "LTE/CDMA" preferred network mode in the Western Chicagoland Suburbs. Assume Sprint's "Connection Optomizer" is enabled. Assume my PRL is being reset at a daily rate both at home and at the office.
Please give me suggestions for correcting these problems, or reply here if you are experiencing the same problems with your Galaxy Note 2.
No Incomming Calls Around Office Location
I work in a 6 story office building located at 1444 N Farnsworth Ave in Aurora, IL 60505. When I enter the proximity of my office (roughly 3 block diameter) I am no longer able to recieve incomming calls. My phone does not ring, I do not receive text messages, I do not recieve voicemails. When attempting a test call from a office landline phone to my cellphone, I get the message "The number you have reached is not in service, this is a recording" or a busy signal. When attempting a test call from a cellphone (Verizon) to my cellphone, I get my voicemail after about 20 seconds of ringing on the line (with no response of the call on my phone). These cases are constant after about 10 tries with each method. Once I leave the proximity of my office, I get a barrage of text messages and voicemails that have piled up throughout the day delivered to my phone. This has happened every day since I purchased this phone. This problem did not occur with my old phone (HTC EVO3D) and does not occur with co-worker's phones (Samsung Galaxy S2/S3) which are on the Sprint network. It may be worth it to note that there are a large number of point to point microwave link dishes (high speed internet from the john handcock center) on the roof of the building, as well as Sprint, Verizon, and AT&T carrier level cellular transcievers.
Outgoing Calls Lose Connection Within 1 Minute
Outgoing call made from my Samsung Galaxy Note 2 fail within roughly 1 minute. I have had times where phonecalls lose connection after 20 seconds, some after 40 seconds, some at 1 minute. There are rare occasions where I have been able to hold a call longer than 5 minutes, but this accounts for <10% of my attempts. I have this problem calling landlines, cellphones, and Sprint Customer Care. When the call terminates, it looks as if the phone is ending the call, rather than service being lost. The CDMA network signal strength meter stays at the same level while in the call, at the point of termination, and after termination of the call. These cases occur in situations where signal strenth is between 75%-100% and the phone is in a non-moving position.
Text Message (SMS/MMS) Errors
I have problems in both my office and home with sending and recieveing text messages. In my office, I cannot send or recieve text messages (within the previously mentioned 3 block radius) about 70% of the time. Once I leave this area, I recieve my day's worth of incomming text messages that have built up, and am then able to send messages as well. Once I enter my home area loacted at Forest View Rd in Lisle, IL 60532, I cannot send text messages, but can recieve them. When attempting to send text messages, I encounter and "Error Code 97". I believe this has something to do with my Sprint supplied "AirRave" Femptocell by Airvana, as this has been a recurring problem in the past with my HTC EVO3D as well. Text messaging seems to work fine in most other areas I have been in other than the office and home.
The Good
My data service seems to work great through 4G LTE, 3G, and WiFi. Never really seem to have a problem with this, even in areas where the aforementioned problems occur. Overall the rest of the phone works great as well, when using it as a tablet, moreso than a phone (since voice/text keep failing).

Maybe you got a faulty phone.. get a replacement?

Yeah, that's my plan tomorrow.

Unplugging my AirRave at home has solved the problem. It must have been keeping me locked onto its tower and not letting me roam onto Sprint's network. This thing has been junk since day 1. They really need to work on their firmware.

Pixel 3 and Pixel 3 XL Wifi causing dropped calls and dropped mobile data

Both my wife and I have pixel 3's, I have the XL and she has the regular. Both were preordered and delivered at the same time, and we are both on AT&T. Since the beginning we have experienced random issues such as the phone dropping mobile data completely even though the signal shows LTE , and having to cycle airplane mode off and then on again to get data back. The other issue is that we both experienced call issues where our end would drop and we could not hear the other party, but they could hear us fine.
I think I may have traced these issues to WiFi causing the problems. When the data drops, I notice that my wifi is on and occurs when I am not connected to wifi (such as an unidentified network) and on LTE, or when I leave a connected WiFi area (like my house) and keep wifi on. We would have to cycle airplane mode to fix this.
For the calls, I had a call drop yesterday and when I looked at the notification bar it showed connected to wifi. I immediately turned off wifi and the call came right back. I thought this was an AT&T wifi calling issue, so I turned off wifi calling. Today, I was at the post office and had to make a call. Soon after connecting, the call dropped. I checked wifi and it showed unidentified network (not connected), so I turned off wifi. The call immediately came back.
So now, wifi is completely useless to my wife and I. Assuming I don't experience any more dropped data or calls, I cant use wifi to ensure good call quality and constant data.
Anyone else experience this? Could this be an RMA issue? Seems weird that it is happening to both phones. Is there a setting we should turn off that could be causing this?

i have a similar problem where if i am on wifi, when i get off wifi my lte or h+ will show bars but have a small x in the bars. i have to cycle airplane mode to get data back after i switch wifi off. i may just make a tasker task to do this.
i had a call from an s9 yesterday where i could hear them but they couldnt hear me. i think i was on wifi. we tried 2-3 times but he couldnt hear me. when i switched to my google voice phone number and called him, he was able to hear me fine.
there is another thread around here about similar issues. i might try to get a new sim card since this one is almost 9 years old.

I may have started that original thread a while ago, but since it was more focused on the data drop thing I created a new thread to help narrow the conversation towards the wifi issue. I went to ATT when I first had the data drop issue and got a brand new sim so it is definitely not that.

Question Phone Suddenly on Emergency Calls Only Until I Restarted It

When I woke up today, I saw that my phone was on No Service and it wasn't just flipping between full bars and no service for a second like it too often does (including dropping calls a couple of times). I tried to fix it by turning Airplane Mode on and back off, but it did nothing. I went to try to manually choose a tower to connect to mostly to see if the T-mobile tower near me was working or not, and there instead of a tower name it said "Emergency Calls Only". It did let me pick from the list and a disappearing pop-up said it connected, but it never changed to signal and stayed on Emergency Calls Only. So, I restarted my phone. Once it was back on, I had signal, but strangely I also got a Gmail notification about an e-mail that had arrived an hour prior, so I guess even my WiFi wasn't working! Bluetooth did connect fine to my Apollo Neuro anti-anxiety device, but the app was messed up showing it at 100% strength on two different settings instead of the strength they were saved at (and were sent to the device at), which was weird. Everything was fixed after the phone restart.
Anyone else had this happen? The signal issues on this phone are really starting to annoy me! Flipping to no service for a second too often, not connecting manually to any other tower (my plan includes unlimited roaming for talk and data) [I'm not sure if auto roaming works since I haven't been where it would be needed], dropping a couple of calls, not sending texts at times, Chat texting dots turning off often (usually fixed by going into Airplane Mode and back), and now this! I love the phone, but they need to fix it whether it is Samsung or T-mobile!

i thought i was the only one. suddenly no service to any calls but data intact. only way to fix is by cycle flight mode.

That sucks. They really need to fix this basic function of this phone!

I've had that issue when getting in areas where coverage is spotty, but never been able to see it go into Roaming..........just "emergency calls only".

It seems that is the issue, that the phone won't roam. That is a mega problem.
My phone was just sitting on the wireless charger all night, and I get full bars (occasionally minus one) here at home, so .
