Calls dropped when EDGE data is present? WTF

So I switched from a blackberry to a Nexus S and I've been using the phone for about 3 months. During that time people have told me they can't get through to me so I did some research and found that once data useage over EDGE is present, calls won't come through? That is absurd to me as calls are far more important than loading a webpage.
I have found nothing to cure this as it seems that unless you have 3G then the smartphone on EDGE is pointless. I did some testing with my blackberry and it seems that since it's such a crappy device for browsing etc. the EDGE does not stay connected long enough to send the call to voicemail, as it is only active for a few seconds to receive or send an IM or email etc.
There is no 3G in Grenada where I am from and this issue is making me regret buying the Nexus S. It's a wonderful device but if it can't receive calls all the time then it's a brick to me.
Is there any workaround to this issue which gives priority to receiving calls over completing a data task?

What ROM? Kernel? Radio?

The phone is not rooted, running the 2.3.2 version, the OTA update to 2.3.3 has not presented itself as yet.

dont get your hopes up. OTA for that ROM is pretty slow, you can manually update it by going to the 2.3.3 links thread in this section. no need to root to update, this update will supply you with a new baseband that will help

Are you aware of the issue I am speaking about? Where the phone does not receive phone calls when an EDGE data conenction is present? From my research it happens to a lot of smartphones where EDGE/GPRS is used even the iPhone, since the radio is shared for EDGE data use and GSM calls.
How do you know the new baseband will help to resolve the issue? In what way?
Thanks for your responses so far.

Because 2.3.2 to 2.3.3 includes a new baseband (radio) update and various bug fixes.
It could be a bug that is fixed in 2.3.3... hence, the new radio/baseband update. (Duh!)
It's pretty obvious you don't know what a baseband is. It's the thing thats responsible for your phone's reception/3G/EDGE/etc signal. So yes, I'm aware of what you're talking about but you're not aware about what I'm talking about.
Not being arrogant or anything but I shouldn't of even responded back to you because you responded pretty rudely to me.

To be honest I didn't mean to sound rude in any way. I sincerely apologize if you took it that way and appreciate your response. The reason I asked is because you did not speak to the issue I was trying to address about the EDGE/GSM not working when the other is working, and I was hoping to hear your thoughts on it.

I did speak to you about the issue. The possible fix would be upgrading to 2.3.3 which would provide you with the newest and latest radio (baseband). The newest baseband includes significant signal improvements and it could fix your problem (big chance it would).

Is this a hardware limitation of sharing the same chip for phone/data or can it also be fixed by software?

its just 'his' problem.. i don't have any problems with calling on EDGE, internet doesnt affect your calls unless you're using WiFi VoIP (or anything related)

It's widely known that on edge, when data is actively transmitted, calls will get kicked right to voice mail. Not much you can do about it.

I upgraded to 2.3.3 last night as suggested and did some testing. When I would load a webpage, while loading EDGE would be lit green and the up and down arrows will be lit showing EDGE activity, I called the phone about 5 times during this process and no call would go through. As soon as the webpage was done loading and the EDGE arrows stopped blinking, the call came through. Tried this multiple times with different apps that use EDGE and while syncing or refreshing such as the Facebook app, no calls would come through once EDGE data was in use.
I did some research and it seems that's just how EDGE works, it gives preference to the data connection and calls get bumped to voicemail once the data connection is active on the device at the time. I know both data and voice can't work at the same time but I was hoping that it would register the call coming in and bump the data off, receive the call, and resume data after, but it doesn't.
Thanks for your help guys, and for the confirmation RogerPodacter, my research indicated such.

Phone call problem.

My phone:
Rom: Insertcoin 3.4.4
Kernel: Bricked v.1.5
Radio: Stock
Problem:
This morning a friend of mine called. We talked about 30 sec and then the call just got silent and we could not hear each other anymore. So he called again 2 or 3 times. And every time whenever I pick up the call just dropped. I've tried calling him too 2-3 times and I just hear one beep (quite like the signal when you are calling him) and right after the signal the call drops. I've tried calling another friend too see if the problem is in my phone and the same. So I've restarted my Sensation and everything was good again.
During the time the problem was going on I was constantly looking at my signal strength and I was trying not to deathgrip my phone. It was 3/5 which is normal in my house but a few times it dropped to zero and I was not deathgriping it for sure.

Bump! Anyone? I think this even happened before and the beep is not the same as ringing tone.

Yesterday I was at a friend of mine. And my mobile internet was not switching on for a long time after i switched on I didn't have any connection. I've restarted my phone and again the same and I received messages about missed calls. I've tried to dial someone but nothing again just beep and nothing more. I've had 2-3 bars connectivity after 15 minutes my phone was working again by itself. Very strange help please.

The only time I recall having issues with the other person not hearing me has been when I've had wifi calling turned on - it seems a little more problematic. If you're not using wifi calling, my only other thought is to try changing your rom/kernel/radio - since I assume your phone used to work correctly before putting a custom ROM.

Before flashing anything custom did you perform a full wipe. Try flashing your RUU. Sounds like it is as, suggested
previously, a WiFi calling problem I experienced when I forgot to do a full wipe prior to flashing s New ROM. I ended up flashing my RUU and started over.
Good luck.

Calling issues? Advanced Calling?

I recently got a GS6 and I'm having problems with calling/receiving calls.
When calling/receiving usually the other person can not hear me talking but I can hear them. Sometimes they can hear me for 30 seconds or so then they can't hear me anymore. I disabled and enabled Advanced Calling and restarted my phone and it seemed to work for one phone call. I only tested it on a short call though so it could of stopped working during the call.
I tried disabling Advanced Calling and made a call right away without restarting and the person could still not hear me. I did see my phone dropped to 1X during the call this time. Does it take time when switching off Advanced Calling for something to happen on Verizon's network?
Anybody else have this issue or a fix? I'd rather not have to do a full reset.
Thanks.
Edit: Just deleted dalvik cache and cache partition in FlashFire and it seems to be working. Will update if I have the problem again.

I was dropping calls regularly. I disabled AC and I have not dropped a call since. I would 'reboot' and double check to see it is indeed off

we had to call and verizon had to "program" some stuff for AC. Try that. worked on this end.

I have this same issue. It has happened to me mid conversation. It is annoying. I didn't have this issue with my G3. I thought it might be because I'm running a room that is debloated. I'm trying to hold on to this phone because I'm hoping the next update to 5.1.1 will fix this issue. If not I'm going back to LG.

With AC off you won't be able to talk and use data at the same time which is a deal breaker for me.

Did you have problems activating AC on your phone? If you don't have it added to your account you have to do that first.

I'm running CleanROM 1.5. I might try flashing it again to see if that fixes it. If not then I will try stock. The problem with 5.1.1 is that it probably won't have root.

Root stock, I have not noticed this issue and this week has been a big phone call week. Lots of long conf calls many times a day.

Thanks for posting.
I re-flashed CleanROM 1.5, so hopefully that fixes it. If not I will try stock.

Re-flashing CleanROM 1.5 did not fix it. I guess I will have to try stock now.

BTW it is quite possible that you are just in an error with bad signal too.

I guess that's possible but I have 2 bars on Band 4. I could try locking into Band 13 but that is congested at times in my area.

Bars are misleading, look at signal strength instead.

Around -105 dBm. You would think if there was reception issues the call would completely drop.

When I lived in an area that had a signal level of -100 to -110 I would sometimes have calls drop and Verizon stated I was in a fringe area and would let me out of my contract.

The thing is only B4 is that high. B13 is around -93dBm.
I planned on doing a test today to see if I stand by a window where I get better signal if that would help. The call went through fine today. I checked LTE Discovery during the call and it said I was on B13 though. Around 10 minutes later the phone was back on B4. I made a call then and the person could not hear me. LTE Discovery was saying around 114dBm. I moved maybe 4ft and the dBm was around 106 and then the person could hear me. If I move 12ft more I'm by a window where I get 99dBm.
So when I sit at my desk I can't make any calls and will have to get up if I'm on B4. I wish I could force the phone to use B13 during calls.
Another issue I had the other day was my phone was only connecting to 1X even though I was in an area that had good 4G. I've always heard Samsung had crappy radios. The only times I would get 1X on my last phone (Droid DNA) was when I was in the middle of nowhere. Wish I would of noticed these issues sooner so I could of returned the phone. :-/

Getting/making calls

I'm on a aosp marshmallow build, and since cm 12.1 upgrade whichever rom, I tried I couldn't maintain a signal level to make calls or get calls while the phone is idle while it's on lte, or 3g. Lte works fine for data. When I'm on 2g all the calling features working fine. I already tried installing different modems and firmwares including but not limited to 44s, cm nightlies, oxygen os. I went back all stock and rerooted and reupgraded to lollipop back then. No solution again. Any idea would help. I searched couple forums, saw other people with similar problems. But not a proper solution. Thanks

Got the same problem, except that 3G works fine for me.
I tried all that stuff too, still waiting for a solution. I hope it's not a hardware issue as it's working fine for everyone else.
So the problem is that I couldn't make or receive calls on LTE. Data works fine. The thing is the call connects, after 2 rings, I get a message which reads "Mobile Network not available." The other person thinks that I made a missed call and want them to call back. The same happens while receiving calls, after 2 rings, it disconnects it. I've noticed that the signal drop automatically after 2 rings. 100% to 0% after 2 rings, and then back to 100% after the call disconnects. This is kinda weird. I called up my service provider and they told me that it's the handset that's faulty. I think that I need to get to OnePlus Customer Care before my warranty is void.
~noob (you gotta start from somewhere)

Yep. Same here. But if you keep it on 2G, then you can make/receive calls. But that means, practically giving up your data

Verizon S10e no longer works on Verizon after outage? Works on Mint sim (Tmobile) no problem.

Hi,
Suddenly on Tuesday when Verizon had the outage in NY my phone started not being able to make calls, data didn't work and visual voicemail stopped working completely but texts worked intermittently. I spent hours resetting my phone network, clearing cache and got no where. Intermittently I could make calls over wifi. I noticed my signal kept going from signal to no signal at all? After several more days of verizon support and engineers visual voicemail started working for new voicemails bit old ones were grayed out. Then today after switching to a new 5g simcard and 4.5 more hours they gave up and said my phone is under warranty and they are sending a new one (assumed refurbished). The odd thing is texts still work over wifi but no data or calls? I also have a Verizon network extender.
Any idea what in the world is going on? Is it Verizon that caused this or my radio in the phone?
Would it be better to send my phone to Samsung for repair or keep the assumed refurbished one from Verizon as my original warranty didn't end until November 2023?
I tried looking around for others with this issue. Is it causation or coincidence this happened during an outage?

Maybe this has something to do with it?

Since you mentioned that your phone's signal was intermittently going from signal to no signal at all, it suggests that there may have been disruptions in the network coverage or connectivity in your area during the outage. This could explain why you were unable to make calls or use data on your phone.

You know I was told an engineer would follow up with me a second time and they never did which is why I escalated things. In total I spent over 16 hours. Seeing the layoffs, I wondered if someone there was like OK want to fire me let me ruin your system on the way out.

I thought the same thing at first but then the other lines I have all iphones had no issue after Tuesday somehow. It seems to be something on their end though as how could some voicemails be locked and other not?
