Hi All -
Sorry for a weird (simple) question:
I am used to GSM / At&T - where if you had a 3G connection you could talk on the phone and be on the internet at the same time.
Is CDMA / VZW different? I just talked to a tech and she said it wasn't possible.
Confused...
-Daniel
According to what I have read on this forum and experienced, with CDMA, you cannot be on the internet and on the phone at the same time.
If I am incorrect, I am sure someone will correct me!
KD8FRE
that is correct. It's not possible on CDMA.
Wow. Interesting.
I guess there's a map for that in AT&T's future.
Thanks all - appreciate it.
-D
I never really noticed any kind of problems with it. I can make a phone call while my phone is tethered and I can still also receive calls, I think it probably temporally boots you off 3G during the phone call but put you back on right after.
Yeah EVDO is "1x Evolution Data Only/Optimized" which means that once a voice call comes in you are switched to 1X mode.
The latest SVDO specification (recently released) allows carriers to quadruple their voice calls and also allows data and voice at the same time. However nobody has implemented this yet.
I believe no one will implement this.... Because all providers are going HSPA or right to LTE... Where we will be able to have data and voice at the same time.
3G - voice and data
You can talk and surf the internet but only if you establish a Wifi connection

or if you use VoIP
Seriously though, what's the benefit of having an internet connection going at the same times as making a phone call? Please note, I'm not trying to be rude about this, I'm just curious about it.
Doesn't navigation(on sprint) use the internet? Im able to talk on the phone and still use navigation
There are some "live caller id" services which will do an online 411 lookup for any number that calls you, plus it's nice to be able to browse the internet to look something up while talking with someone (usually handsfree) for example if we're trying to decide on a movie or dinner or where to go out - all very handy to have a simultaneous internet and voice connection.

Two big ones:
1. Conference calls with email coming in. Like - your next meeting has been moved (exchange, push).
2. On phone call - someone asks a question that needs internet connection (I found it this way - they asked what the weather would be like on Sat (it was Monday). I said... hold on a sec... I'll find out... then realized that there is no internet... so I pulled my iPhone out of my pocket and checked it instead. Again - this is something that AT&T does today - just didn't think CDMA was behind the curve on it...
-Daniel
Cool, thanks for showing me the light
My problem (with Sprint) when I had to have a CDMA device is that there is a difference in signal between EVDO and 1X. For instance, I had full signal for EV, but hardly any for 1X... Thus I could be on data all I want, but I had troubles with phone calls....

Hello.
I know similar threads can be found on related subjects, but I've easily gone over 25 threads and have made 0 progress.
I recently flashed {ROM} Ninja-07061 on my Inspire 4G and I'm absolutely in love with it. So far, it's my favorite ROM and I really want to keep using it.
The problem lies in the fact that I can't send or receive any MMS messages without first connecting to the mobile network, something I haven't had to do in all the non-cyanogen mods I've tried.
I've tried changing APN settings, using different messaging apps and pretty much all I know I can do without risking any damage to my phone.
Any help would be greatly appreciated. Also, if there is anything I should post that could aid in solving the problem, please tell me, I am very very new to this entire android thing and I'm trying to learn as much as possible, but there are things that I still have no clue about.
Thanks in advance.
Possible Solution
I've had a similar problem with earlier versions of the ROM. I don't send enough MMS messages to know if this works, but at one point I had added an MMS-only APN. Something like what is mentioned in this thread:
http://forum.xda-developers.com/showthread.php?t=1109983
Let me know if it works.
Thanks... unfortunately it didn't work :/
I've tried many different APN options and I still get the same results. MMS I received are stuck at "downloading" and ones I send are stuck at "sending".
The issue is with the way cm based Roms change the apn when disabling data. They disable the apn completely. While other stock based rom's don't disable the mms part of it. MMS use a little but of data and that's why you see the data arrows work when you send an MMS .
Okay, let me see if I understand.
CM based roms don't let me download or send MMS because they don't automatically connect to the mobile network to do it?
I noticed that I can send and receive while on the mobile network but not while disconnected (or while I'm connected to wifi).
Originally this worried me since I have a free MMS plan, which I believe should work separately from the mobile data connection, but I don't really know how it works (because I'm a total noob >.<).
I've read a little and it seems that MMS will be free, but they still require me to be connected to the mobile network. From what I can discern, this means that most stock roms (sense based) force a connection whilst sending or receiving an MMS and CM roms don't?
If that's so, is there a way to get the messaging app to force the connection, or will I have to connect to the mobile network every time I want to send/receive an MMS? I try not to have the connections enabled due to battery life and the fact that my data plan is capped.
Sorry for the wall of text, just trying to get used to the entire android scene :/

You got it. The only way I was able to do it is to activate data (which I normally keep off due to wifi everywhere and being on a prepaid plan) when I send an MMS. There are apps that control what can connect to data. I think apndroid is one of them.
The reason sense works is that it has its own built in MMS settings seperate from the apn settings.
Okay, guess I'll have to try some stuff out, at least I can rest easy knowing what's up now.
Thanks a billion.
No problem.

I know this is being discussed in the Development forum, but I can't post anything there because I'm a new member. Anyway, just wanted to get some discussion going regarding MMS capabilities when hooked up to T-Mobile's Wi-Fi Calling feature. It seems like many of the people in the development forums are under the impression that the phone switches to cellular data to send/receive MMS messages, but I'm pretty sure that's not the case. I use Wi-Fi calling at my house where there is absolutely zero cellular reception and I can definitely send MMS messages as long as I'm on Wi-Fi. I'm not a technical expert by any means so I have no idea how exactly it works but it shows the "G" icon when I send an MMS (which I believe stands for GPRS) and MMS messages can be sent and received.
Just wondering what other people's experiences were regarding this.
Yes the "G" doesstand for GPRS, but if you are seeing the "G" when you are sending or receiving a MMS. Then this means it is kicking over to your mobile data to send or receive the MMS. I like you live in a very weak signal area and even though I have my WiFi Calling on at home my mobile data kicks on when I send or receive MMS. And just like you it is usually the "G" or the "2G"(Edge) symbol.
Now I am no expert by no means on this subject but I can tell you that MMS strickly uses mobile data as my WiFi calling adds non when I sendor recieve a MMS at home. I usually have to set my device in the window sealto get it to send or receive a MMS.
That's the thing, I get absolutely ZERO reception at my house (GPRS/EDGE/3G) but I can definitely send MMS messages as long as I am connected to Wi-Fi and actually have the Wi-Fi calling app enabled. I noticed the same thing happens when I open up the T-Mobile My Account app to check minute and data usage. The app doesn't work over Wi-Fi alone (ie. connected to Wi-Fi but without the Wi-Fi calling app enabled) but it definitely works if you have Wi-Fi calling enabled. Maybe I can get a video of it to show you what I'm talking about.
nubletdeluxe, you are right. When on WiFi calling, it uses WiFi not cellular signal to send your pics. Since the upgrade to ICS, I have tried to send many picture messages and without WiFi calling enabled, 4 out of 5 would fail and if they did go through, it would take forever! Since enabling WiFi calling, I also see the "G" but it takes seconds to send a picture message and have yet to have one fail.
Hey guys I did a search and found nothing. Any time I'm connected to Wi-Fi, I can't receive calls or texts. I'm on Sprint. Anyone else have this issue?

Yes, have done tons of research and am having a similar issue. It's believed to be software related. If LTE or Global are set as the "Preferred Network Type" under Mobile Network AND wifi is turned on, then the mobile signal cuts out when it goes to sleep. With 3G set, the phone works fine with wifi turned on. I've tried wiping the phone and also loaded the factory 4.4.2 image via fastboot this morning and still have the problem. Some people have RMA-ed their phones and still report the issue, so it must be a certain combination of settings. It's also being reported from Sprint and T-Mobile user, so it's not restricted to just one network. As for me, I'm on Sprint in NYC, have an AC router and using an Airave. My Galaxy S4 didn't have any problems.
Here are a few threads that I've found:
XDA - Signal Problem
XDA - Signal issues with new baseband solved by flashing older baseband
On Google's forums:
Nexus 5 sometimes doesn't ring when people are calling
Thanks man, I had read the Google thread but hadn't find the XDA ones. I'll try forcing 3g while on Wi-Fi.
No problem! If you're on Sprint, there is also this:
Circuit Switched Fallback Issues on Sprint
I'm in an area that is reported as not having the issue, so it's not that for me. Plus, I'm on 3G with the Airave. I remember having the HTC Mogul on Sprint and for a while it would just die if the signal was roaming. An update fixed it, but it wasn't fun. At least in this case the phone still works, not as advertised, but it works. Here's to hoping that it's fixed soon!
I'm the Tmobile user in the Google discussion. It's an annoying problem and hope it's fixed with 4.4.3. However the issue just happened to me in the last week before I got the 4.4.2 update. So I'm not sure what could have happened from a month ago when I got the phone until a week ago. Haven't installed any new apps since then.
This does seem to be working now that I am forcing 3g
Weird, right?
4.4.1 and 4.4.2 both have the same baseband and kernel. That's about the timeframe when the updates both came out, so I assume that maybe 4.4.1 is when the majority of users started seeing issues pop up?
From what I've read, this phone handles cell signals much differently because of the newer LTE TDD. It could be any number of things really, but I don't have the expertise to examine the code to see what was changed between the 4.4 and 4.4.1/4.4.2 baseband. I do believe that all of the Wifi and cell signal issue posts that are popping up now are related though.
I'm also noticing my wifi speeds bouncing all over the place (from ~180Mbps -- ~500Mbps) and I'm only a few feet away from my router. I have a Netgear r6300v2 AC router.
12/14/13 Update: I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue, starting on 12/19/13.
The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and it's causing this conflict. That's why everything seems to work fine when 3G is set as a preferred network.

thanks man!
do we have any update on the situation?
Yeah I wish there was an update soon because this problem is starting to become very annoying. Twice this week I had to check my Google Voice because my Text didn't go through on my phone
Anyone have a fix for this yet?
Does anyone know if any custom roms fix this?
I've read Google is aware of the issue and speculation says they will fix it with the 4.4.3 release.
questions:
(the 1st is stupid, but i'll ask anyways) - when this issue occurs, is the phone set to **wifi only** with 3g / lte in airplane mode?
or does it occur when just setting up wifi in ADDITION to 3g / lte?
&, when you typed Receiving no calls out texts while on WiFi , is your application for texting, hangouts?
if it's hangouts, then google neutered it to only allow text thru the cellular network,
but if you're simply joining a wifi hotspot at work or home, with your cellular network enabled, it SHOULD go thru, ive never had an issue like that with wifi toggled.. even with 4.4.1

maybe it's simpler than one would expect (shot in the dark)
to sum it up;
on our new triband spark capable phones, does *automatic vs home only* in (change the cdma roaming mode) mean what we THINK it means in relation to it's single chip, single path architect??
back when, in dual pathed phones it MEANT roaming in another provider, when ecsfb, carrier aggregation, spark wasn't a thought..
but these newer triband phone are different beasts, & the effect of the patched worked, fit n finished network of cell sites of upgraded , non upgraded network vision, does toggling automate for smoother performance between these sites on these triband devices, with single paths....?
something as simple as a network toggle, to aid service (on the mobile client side) in this -
"In a CSFB environment, 2 important concepts are employed viz., Mobile Terminating Roaming Retry, Mobile terminating roaming forward. We will discuss MTRR in this blog. In a typical operator environment, voice coverage for the entire geographical area is achieved by employing many MSC’s. These MSC’s may be a mix of Legacy MSC (where upgrading is difficult/impossible) and next generation Softswitch MSC’s. In order to support CSFB, the MSC needs to be upgraded to support SGs interface, so the issue is how do we support CSFB when the UE is in Legacy MSC coverage. This is where MTRR helps in call delivery to Legacy MSC that does not support SGs"
from being parked on an lte channel, being called & successfully *inter-roaming* to 1xtt voice, evdo data (if used), then back to lte parking & usage when applicable..

just a note -
if you look at slide 7 on the qualcomm snapdragon 800's chipset (you all already know this)
http://www.slideshare.net/jjwu6266/qualcomm-snapdragon-800-mobile-device
there's only ONE chip to handle wifi, 4g, 3g, bt, etc..
with lesser BoM (bill of materials) just maybe, top level s/w userspace toggles, handle more than what meets the eye, the point i was making in another thread..
which not only effects our nexus 5s, but even other phones in various ways depending on the implementation of sw/hd, of the same chipset family..
& sprint has mentioned for the forseeable future, of providing phones, with these types of chips from qualcomm..
~go figure~

the ONLY reason i pointed to the network settings *home vs automatic* in this situation, is because,
the qualcomm sd 800 is an asymmetric multiprocessor, (as will future chipsets be) & you're losing other core networking functions, while gaining another, when you SHOULD have available ALL facilities -
**ASMP vs SMP**

It actually occurs when the phone is connected to LTE and WiFi together. If my settings were to connect to 3G along with WiFi, SMS works fine.
I have to manually change my Mobile Network settings when I get to home or work, where I will be connecting to WiFi (note cellular service is always ,on, I didn't mean to make it sound as if I am trying to send SMS over WiFi). So when home I turn on WiFi along with 3G connectivity and when I leave I turn off Wifi and switch to LTE.
This issue has been happened while unrooted and running stock ROM and it still happens while rooted running Cataclysm.
Also note, the SMS we miss never will come through, it's not as if later on the message comes through...It's gone forever. It also prevents calls from coming through, it's not just limited to SMS.
