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.

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

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....

yeah honey, i'll meet you ... where was that? let me punch it in my google maps... o wait CDMA FAIL
I have had a crazy time both with wifi calling remaining connected (suffered sudden drops), and further SMS over wifi seemed spotty at best.
Part of this was caused by either a bad SIM card, or deletions of stock apps and/or services...which now have been fixed.
At the moment everything is working fine. Don't know if this will affect anyone, but I thought I would just add to the library of knowledge.
First, once I got wifi-calling working (meaning the status bar icon was no longer red), I started to read the log files and realized that every time the wifi was reset, wifi calling would not consistently restart.
What I have realized is that wifi-calling and SMS are dependent on TMOs mobile network via wifi. However, any internet connection is simply that...and any apps you have like FB or Google Voice will work with that wifi internet connection. Conversely,the TMO wifi-calling service/app either connects on a different layer (such as the IP layer) or uses some unusual node-based connection to traverse the 802.11 frequency, over your ISP's and other networks to arrive at the TMO servers which then are linked into the mobile network. You can see this by downloading an app that triangulates and provides tower locations nearby or gives you other mobile network data (i.e., CID, etc)... That data is either not decipherable by the app trying to get this data, or one gets unusual info when compared to non-wifi calling. Bottom line is that there are two separate signals being carried by the wifi: "data" and "mobile wifi calling" and they are completely different.
Another example of proof: if you are having difficulty with SMS using your wifi internet connection, try sending the SMS via Google Voice. If you have an internet connection, it will go through immediately. But regular SMS has problems if wifi-calling is not working correctly.
And one of the biggest culprits of this is wifi fixer or other similar wifi connection apps. Although it's only a guess, the "scan" these apps do are likely a simple ping to determine status of the DATA connection.
I shut off wifi fixer (but left it as a widget to use as needed), and I have perfect wifi calling and SMS.
Whatever criteria wifi fixer apps use when deciding to reset or reassociate the wifi connection is not reflective of the integrity of your connection using wifi calling. In fact wifi calling may partially interfere with your data connection which will typically trigger a reset by wifi fixer.
From now on, if I am planning on simply surfing the web and my wifi signal is less than optimum, I will turn on wifi fixer. Otherwise it just tears down wifi calling connection.
Hope this is of use.

Thanks for sharing your experience. I have an issue where over time Wifi calling disconnects even though wifi is still working. I have to re-toggle wifi to get Wifi calling back. It's very annoying.

Although there have been occasional exceptions, it's unusual for a wifi call on my H1s to last longer than about a minute before dropping off/disconnecting. When this happens, the call time counter changes back to say "Dialing." Of course, there is no dialing, just dead silence. There are no other signs of a problem, no error messages, no indicator icons, etc. On the same wifi network I can make long uninterrupted calls with our older MyTouch 4G - no issues at all with wifi calling.
I'm running unrooted, locked, stock ROM (for now). I don't think I've removed any apps and I think the only wifi-related app I've used is Wifi Analyzer. Could you offer suggests on how to debug this? The firmware update didn't give any improvements. Should I ask Tmo to provide a new SIM card?
Thanks -

Well the first thing I would suggest is a factory reset. This being the most simple option given your phone is not rooted and on stock. The strange part of this is the "Dialing" instead of the normal keypad (which typically reverts when a call is disconnected).
As far as a SIM card, do you ever get any SIM card errors? Like "ER05" or "REV99"?
These are typically the errors of faulty cards or a bad wifi signal. Check out an app called Network Signal Info....it will tell you the strength of the wifi signal compared to the mobile network (although its not always reliable).
Let me know what a factory reset does. All of your apps will be restored by google (and their are apps to modify this restore as well).

Didn't reset yet, want to test a little more.
I've never gotten a SIM card error. The unexpected "Dialing" with the End Call button still showing is the only indication something is off.
Tonight I ran a few tests calling between our 2 Android phones in the same room, same wifi. 3 calls 1S to MT4G: 2 were perfect and lasted several minutes, while the middle call disconnected after less than a minute. 3 calls MT4G to 1S: all 3 went directly to voicemail, the 1S didn't even ring. Now I recall that's been a complaint before - that calls to me go straight to voicemail when I've been on wifi calling.

Are you sure wifi-calling is on? Do you have the blue icon in the status bar?
Sometimes this isn't on, even though wifi is on and you are making a call.. Not sure if that is intentional or not.
Just in case... The switch is in settings> more (under wireless and network buttons)

Yep, it's on.
Just to be clear, the H1S has received calls when wifi calling is on, it's just sometimes that they go directly to vm. For example, as I'm typing the phone just received a wifi call and is handling it fine, hasn't dropped after 3 minutes.
NO CONSISTENCY, BUT USUALLY DOESN'T WORK.
A factory reset did not fix the problem.
Hi people!!
Since i own this mobile, i've used several official and custom ROMS and i detect that when i'm using 3g phone calls do not work properly. I have to reboot the phone to be able to call (or receive a call) properly but after the first call i detect this issue: when i call i do not hear anything, the same if i receive a call...
Anybody knows how to deal with this issue?
Thanks in advance!

No offence brother but its for the ROMs / MODs related issues only. Moreover if stop people from making threads then we'll never get a Q & A section like others have & our general section will be always messed up. That is because the criteria for getting the section is to have at least 1000 threads or 10000 posts in the General section, so it would be in our interests to allow people post and make threads. We'll get a cleaner General section in return.
I think he's taking about calls made using the network.

Are you talking about normal voice calls on 3G ? Or video calls on 3G ?
I have made & received voice calls via the network while on 3G without any problems. Check if its a network related problem by using different network providers SIM card.
Your problem could also be caused due to plugging & unplugging of the headset from our handset. To solve it you'll have to plug & unplug the headset a couple of times and then check if its solved. Search for a thread within the general section here itself related to the headset problem to get more details.
Hope this helps.
I mean normal phone calls with 3g activated. It's the situation when i'm not able to make or receive phone calls or receive them properly: if i switch off data connection then phone calls work again properly, if i change data connection to H+ phone calls work properly, or when i have wifi on phone calls work ok. It's only when i have 3G activated that phone calls do not work properly...
Hope it's understood!!!

This is a pretty peculiar issue buddy, I suggest you to temporarily switch the SIM being used in the handset to confirm whether or not it's network related issue.
BTW how do to switch between H+ and 3G data networks?
Here in India it switches automatically depending on the coverage available.
Do update us on the progress.
^^
i think its 3g whn its just connected in 3g mode and becomes H whn we start downloading or some data transfr work initiates....
I rarely see H+ in my cell
I think these symbol denotes speed of the network data and thrs no way to switch between 3G or H+

3g means 3g capable network, when data transfer is in progress it will display as H or H+.

[Not Fixed] see bottom of this post.
It is fairly easy to install a new D6603 to work completly on the AT&T network. It is not so easy to find the answer of how to do it in the threads and posts. I tried many suggestions and wasted a lot of time. Hopefully this will save you from that fate.
First you must know that you can't use the IMEI number of your new phone if you want it to work completly as it should. If you use the Z3 IMEI you will have trouble with data of various sorts and the phone will go off line when on LTE after 20 or 30 minutes and you will not receive calls or SMS messages. I do not know why but it has been suggested that the AT&T network does not recognise this phone so it causes trouble.
If you have an AT&T nano-sim from your old phone then just put it in the phone. (Cut downs work but can cause other problems some say.) When the SIM is inserted for the first time into a new phone there is a prompt that asks if you want to download the APN. Hit 'yes' and the phone downloads the APN itself.
If it does not ask then go to Settings>More>Mobile Networks>Prefered Network Type and be sure LTE (Preferred) is selected. Then connect your phone to the internet and then go to Settings>More>Internet Settings and select AT&T. You should be good to go.
If you need to get a nano-sim then go to the AT&T store or call and they will give you one or send you one for free. You will need to use the IMEI number from a LTE phone that is already on the AT&T system. You can use your old phone or borrow the number from someone. If the rep installs the sim in the Z3 with the 6603 IMEI don't worry. Just call support later and tell them you sent your new phone back and want to go back to your old IMEI or have a new IMEI (from an existing AT&T phone). They will enter it and off you go. The phone from the IMEI will show in the picture on your account page. Big deal!
Update: This worked for hours last night but this morning it is back to not receiving calls. Simply turning wifi off and it began to receive calls as GPRS was switched back on. My wifi was on which has been said to cause problems. I will test with wifi off and report back. Had "no service" instead of AT&T on upper left of lock screen. A full shut down for several minutes than re-boot solved that.
YMMV. I've been on ATT with a Z3 purchased from Sony store for several months and it was registered in an ATT store by scanning the IMEI off the box followed by updating Internet settings in Setup. ATT online shows unknown model but everything works including LTE and MMS. There is something else involved when problems like this occur probably some setting not getting reset. I registered the Z3 on a new line with a new Sim card because I wanted to take my time moving stuff off my old phone--this may have avoided the problems.

AT&T's system sometimes takes a while to get updated with new IMEIs that trigger LTE provisioning for a users' account.
Once your account is provisioned for LTE you never have to worry about it again, but sometimes if you have a phone the system doesn't recognize, it is a pain to get AT&T to properly provision your account. Supposedly properly trained in-store reps can do it - the key being "properly trained" - Never try to do anything "unusual" by calling AT&T customer service, and NEVER use a franchise/kiosk in-person for service - make sure you're at a corporate-owned store! Even then, some stores might have incompetent staff. I've been lucky that all of my local corporate stores are pretty well staffed.
So you are saying that your Z3's with wifi and LTE on with AT&T are working as they should?
With LTE off my phone responds normally with wifi on. With LTE and wifi on it will not respond to calls after a 30 minute sleep. It does not show missed calls. Calls go straight to voice mail after 2 rings. Could you tell me what level your LTE dBm's are? Thanks!
I was told not to give them my imie# but, after recvng the minisim I had to call them in order to 'provision' it to work at all and they needed that #. I have never had any problems personally and am assuming this may be because you gave them the wrong #. Again I am only guessing. Oth, if I had had a different imie to give, I would have done so myself.
It is very strange and I am feeling it is more signal strength related than how you provision your phone. (Once it is provisioned correctly.) It seems that more people have less problems when they already have a nano-sim and just plunk it in the new phone. This might indicate that they already had a strong signal from the get go. My old HTC One + get's a better signal than the Sony in the same locations with the same (new) SIM. With the Devilcase bumper on it gets 5% less. My very limited tests yesterday seemed to indicate that it was signal strength related. I am not enough of a conspiracy theorist to imagine that AT&T would program their system to not function correctly with sims that are provisioned with these Sony phones which they are obviously ignoring for some reason. Or am I?
I had all kinds of problems with the Z3 on AT&T. The IMEI caused an issue since AT&T linked it to a flip phone and therefore couldn't provision LTE. I changed it to an old AT&T LTE device and then I was able to get LTE but was having the same issue with calls going directly to voicemail and texts showing up hours later in bunches. I found the solution was to switch off LTE in the quick settings menu. All calls and texts came through and on time while LTE was off. If I needed a data boost to stream, I turned it back on until I was finished streaming. This was while on KitKat. After upgrading to Lollipop, I was able to keep LTE turned on and calls and texts still arrived on time.
I use data rarely. Mostly wifi. If I don't leave LTE on, my phone reverts to wcdma preferred. And why can't LTE just work without me having to constantly turn it back on? What bugs me is having the APN settings greyed out. I want to be able to turn it off. If anything it seems the phone itself is preventing me from accessing the sim. It feels like I'm borrowing something which contains lots of MY private data. I know my phonebook is stored locally but I also noticed there is no option of specifying the sim or not. Anybody know how to switch APN on and off? In fact, overall even rooted, I still feel like I have almost no power over it. I can't even disable the cellular connection without going full on airplane mode and I do not trust that. I don't even fly so that needs work for sure. Dumb question but could I buy a working nanosim from say 7-eleven that my apn switch will work with?
"Anybody know how to switch APN on and off?"
On my Z3 on OTA stock Lollypop I have an icon in quick settings to turn LTE on and off. Drag two fingers down from the top of the screen. If no LTE icon then select the pencil icon at the top and select the LTE icon. There is also a mobile data icon switch there.
To turn off your radio completly you can get the Advanced Signal Status app and select additional info at the bottom and click phone information and turn off radio. Probably a number of ways to do it but that is one.
Sim contact storage was a way to move information from phone to phone. You can still do it but not really necessary with cloud backup and storage. Google does it for me without me having to do anything which I like. I still save contacts to the sim just because I can. Export and import in your contacts app menu.

Works fine here. I don't pay attention to the dBm estimates since these aren't measured with calibrated test equipment and vary widely. Those numbers are basically worthless.
The only valid comparison is data performance in a given environment (ideally a difficult weak-signal one) - and at my desk with very weak signal, every phone I've ever used performs similarly to the Z3.
"Those numbers are basically worthless."
True, but we have narrowed this down to the possibility that it might be signal related so it is worth a shot. If people whose phones are working fine would measure the LTE dBm on Advanced Signal Status at the location where their phone sits and works well the most we might possibly see some measure of difference in the phones that are not working. Most of the non-working phones seem to work sometimes so signal strength is the next best parameter to rule out. Thanks!
Here are the screen shots of my phone with LTE on, LTE and wi-fi and LTE off and wi-fi.
How do the working phones compare? Does your CDMA (voice) also go to 0% when LTE is on and GSM = n/a?
Thanks. I think adv sig nfo actually works. I'm amazed actually. I can't find the phone's native greyed out apn switch anyways which really makes no sense.
I'd like to force my Pixel 7 to disconnect from any mobile network, without using airplane mode. Do you know a way to achieve this?
Reason for asking this: I will travel abroad and use a secondary SIM to provide me with data, while using my primary SIM with voWiFi (or Backup calling). That'd would keep me reachable on my phone number and allow me to make calls/SMS @home at local rates.
The reason for having my primary SIM disconnected from any mobile network is due to the fact that my primary carrier will charge me for calls/SMS depending on the latest place I got connected to a mobile network. They charge roaming fees even when you're using voWiFi in airplane mode! I have tested this already on a previous trip.
One way would be to select a network manually, or a network that I know it won't connect. However, if I turn on and off airplane mode (to take a flight), the phone will connect to the latest network it connected successfully to.
So my strategy is to connect manually to my home network at home, hoping the phone doesn't magically connect to a network. That's why, I'd like to really make sure that the phone can't connect to any mobile network, just to be sure it won't connect to a network while roaming. But only on the primary SIM. For the other SIM I do want to get connected.
For those wondering, my carrier is T-Mobile NL.
Try messing up the apn details on your sim when abroad. That will prevent connection
The issue is that messing with apn won't prevent the phone to register to a roaming network. That alone will tell my carrier where I am and charge roaming fees accordingly...
@jasalta387 Interesting problem for sure. Can you forward your calls to the secondary (travel) sim and use WhatsApp or Signal to call on wifi? Or leave an auto message giving your foreign number. Any time you connect to the primary network you will be charged, no two ways about it on an Android device. I do believe the iPhone has that capability however. Even if you receive a text on the primary you will trigger a roaming charge. Perhaps the only way to avoid that is turning off the sim entirely while traveling. See if they have an inexpensive international plan?
Indeed, iPhone can easily be disconnected from a cellular network by selecting one that doesn't register. That setting sticks even while cycling through airplane mode or a device reboot. On Pixel this is not the case. Pixel will register again, hence my issue.
I know I could rely on 3rd party apps or services or call forwarding. Problem is that I then need to redirect all people who could reach me to them somehow, while using wifi calling is just fine. Even SMS come and go through it. I just need to not make my carrier aware I'm overseas. Hence my question.
I could use a second device that provides me data and keep my phone all the time in airplane mode. This needs that I carry the two devices all the time with the logistics of charging two phones and all of that. I just want to do it all with my Pixel.
I was thinking one thing: I need to go to the US. Is 3G dead there for good? Because then I could tell my Pixel to use 3G and not allow 2G. That'd keep it away from any accidental network registration upon landing.

I'm intrigued by this and would love to find a solution for you. Oh yeah, 3G is dead across the US from all reports. So I'm trying to parse this scenario, let's see if I get this right. You want to have phone calls come into your primary phone line (Sim 1) but no network connectivity for data, right so far. Also you want SMS to the primary while roaming. The problem is that even if you don't get a phone call or text the connection to the network alone will trigger a billing instance, right so far again?
My daughter has an iPhone and turns off data on the sim but can get phone calls and text. As soon as she does though there is a daily billing charge of $10 because she's outside the US. I also think she can connect to wifi and make calls and text without a carrier network. But I'm not sure about. But that aside, how would you like it to work? Would you like it to connect to the network but not get charged unless you get a call or SMS? Because once a call comes in you're roaming charges will ensue. In airplane mode and strictly wifi there should be no charges but you say they bill you anyway right? Are you sure you didn't get a text or something to trigger the charge? I hope I'm reading this right.
My carrier bills calls and SMS based on the country of the latest connected cellular network. So if I don't connect to any network while I'm abroad my carrier will think I never left the country.
I don't want neither data nor calls/SMS on my primary SIM using cellular while abroad. I can get all calls and SMS via WiFi calling on that primary SIM. To get WiFi calling when I'm abroad I will use the data connection on my secondary SIM or any WiFi network.
Because of the need to get the secondary SIM on, airplane mode doesn't help me. So I need my primary SIM to never to any cellular network while I'm abroad.

My carrier bills calls and SMS based on the country of the latest connected cellular network. So if I don't connect to any network while I'm abroad my carrier will think I never left the country.
I don't want neither data nor calls/SMS on my primary SIM using cellular while abroad. I can get all calls and SMS via WiFi calling on that primary SIM. To get WiFi calling when I'm abroad I will use the data connection on my secondary SIM or any WiFi network.

And if you turn off the sim then even WiFi doesn't work on your primary number?
If the SIM is turned off, then you don't get WiFi calling
Try the 4636 menu
Choose the SIM you want from drop down
3 dot menu top right
Disable data connection

Is it possible to adjust the order of airplane mode / network /wifi on-off so as to not allow the sim to connect to the network but still allow wifi on the sim? So for instance, disable the sim, turn on airplane mode, turn on the sim and then enable wifi calling while in airplane mode, turn off airplane mode with data turned off on the sim. I can't believe with no data, calls, sms and only wifi the carrier will charge you roaming. That just doesn't seem right.

I don't know if you would follow this suggestion...
But in case you are interested in it, this sounds like something you could pull off automatically with something like MacroDroid or Tasker or some other automation app -- even without being rooted! But I concur, it doesn't make sense that a carrier charge roaming when there would be no data, calls, or sms but only wifi....I'm of the opinion (previously stated somewhere in the thread here) that you might've either misread the bill and/or accidentally "caught" a text or transferred a byte of data and it triggered...
Hey there, I know it sounds harsh that a carrier bills this way. It is verified and discussed in a local forum here (in Dutch) https://gathering.tweakers.net/forum/list_message/74880578#74880578
Of course, here there are a few things at play:
1- the carrier wants to have a clear way of communication and support. If you are abroad, those are the prices you pay for. That's it. You know it for sure. They don't want to have to explain how to turn on VoWIFI and explain how to make that working for every phone, or explain to you that you made a call thinking you were on VoWIFI while you weren't. Their approach is crystal clear.
2- the carrier makes some extra income this way. While travelling in the US: for every SMS sent they charge 0.51 EUR, calls placed 1.27 EUR, calls received 0.76 EUR and 2.50 EUR per MB of data. For data, they sell some passes that makes the price more reasonable. Note that unlimited plans for domestic data/calls here start at 25 EUR per month.
3- In The Netherlands (and for pretty much every country in EU) people rely quite a lot on 3rd party apps for calls and texting, especially when you are abroad. WhatsApp is the go-to service, even for domestic communication. People don't even bother using their home carrier when travelling outside of EU. They just remove (or disable) that SIM. So the high cost of roaming is usually left to business users for which companies pay or make better deals with the carriers.
One thing I didn't mention is that in NL, pretty much all carriers limit VoWIFI to Dutch IP addresses. To use VoWIFI you'd need to use a router that tunnels all IP traffic via a VPN that has an exit point in The Netherlands. That's how I conducted my test and verified that all activity using VoWIFI was billed using the same fares as if I was using a roaming cellular network.
I want to try this using a secondary SIM from a Dutch provider, which will give me the Dutch IP address. Backup Calling on my primary SIM will make that SIM to connect to VoWIFI. But to get my home fares, I really need to make sure that my primary SIM doesn't connect to any network while I'm travelling (hence my original request).
