voice & data simultanouesly

i was wondering today - why it isn't possible for the htc tp2 with a 3G connection to have a voice call and a data transmission simultanouesly?
this was no problem for the nokia n95 8gb with the same sim card in it?
is this a configuration thing or is this a "missing feature" on wm devices?

AFAIK, you have to be in an HSDPA (3.5G) area to allow simultaneous voice and data connection. Just 3G will not suffice.

You should be able to do it. Even with only 2G you can have both simultaneously (obviously slower but still).

not 2G, class for GPRS and EDGE will only support suspend feature. 3G is your answer, but it depends on both the device and BTS's device.

My Tp2 should be here in about a week.
I have not used edge on my MDA. So I ask this question:
Is it an easy affair to enable the "Suspend" feature on the phone? I don't want to miss calls cause I am streaming music while I drive...
Thanks

normal plain jane 3G can do voice and data. (atleast in the US)
CDMA cannot under any circumstances.

can we try to stick onto "real testing" -
any TP2 users here which can try if it is working on your phone?

simultanouesly? ... so you have made a call and during this call used a data connection (for example opera browser surfing a website?) ...

confirmed,
works on HSPA mode, 3G is not stable, sometimes it disconnect
suspended on 2G and EDGE

it seems to me only on my tp2 this isn't working ... ;/ ...
even after I installed some cooked ROMS ... very disturbing ...
has anyone else ideas? possibly a registry setting? ...

Works fine here on T-mobile. Simultaneous connections on 3G. One or the other on EDGE. If you stream data on EDGE, voice calls get priority and will suspend the data connection.

Can't seem to connect to the web (Opera) while on a phone call (voicemail). This happens while the phone is on T-Mobile US 3G.

Use 2G (EDGE) only AT&T?

I will be using the phone on AT&T and I was wondering if the option to turn off 3G is present or use 2G networks. This would be under mobile networks. I ask because I get better coverage on EDGE and have wifi. AT&T has also removed this feature on their Androids for god only knows why.
So can anyone using the phone on AT&T comment whether or not this option is there and if it works correctly? Thanks

Of course. Here's the standard mobile network screen:
But when you're on WiFi it doesn't matter. It disconnects mobile data anyways.

Thanks. With my iPhone 4 I was able to turn off 3G and be on Wifi and have a very strong signal versus leaving 3G while being on Wifi and having 1 bar.

You can manually drop to "2G only" when you turn on WiFi if you want, but it automatically disconnects data when you connect WiFi. All phones hold onto signals to different extents. if you find your phone always on the edge of a 3G/2G handoff, the "2G only" switch will do it for you.
You can always grab a widget to do so as well. Most of the popular ones (I use Widgetsoid) offers a 2G only/2G+3G/3G only toggle type.

4G Problems

I use mobile data almost everyday but I have some problem with 4G LTE. If my network type is set to 2G/3G/4G, I get 4G signal and it work for just a few minutes. After a few minutes, all signal disappear. I don't have any Internet connection, not even cellular signal for calls.
But if network type is set to 2G/3G, it works flawlessly with 3G connection. (although I face some problem with 3G sometimes, but that is another story).
So did anyone else face this problem too? I'm using U Mobile in Malaysia which uses the 2600Mhz band.

First step is to always check your APN settings. Make sure they are identical with that of your carrier for 4G LTE.

Does this issue occur in one location or various locations? Please test with WiFi disabled.
Also recommend using ASUS ZenUI app called ASUS Support. There are several helpful tips with basic troubleshooting techniques for your device including including 3G/LTE troubleshooting. Please go to Apps/ASUS Support/Assistance/3G-LTE-WIFI-GPS/Weak or disconnected 3G/LTE signal.

I already set APN settings to what it should be but still no luck. And nothing in the Asus support app is helping.
I noticed that it happens to me when I'm on the go or I have a few 4G cell tower around me. I suspect it's because of switching of cell towers.

Got the same problem. moreover, my wife has an iPhone 6+, we have the same carrier but when we go in not so well covered areas (up to the alps for example) she always has signal while my zenfone loses sim1 for data&voice. sim2 is available but gives only voice coverage btw. signal detection is far better on iPhone. I've tried with another carrier, same outcome.
It seems that sim1 only works with very strong signal from the carrier

Try disabling the second Sim and then using 4g on the Active Sim( 1st One ).
On my device, the second sim's signal seems to interfere with that of the first one.
I can use 4G on 1st Sim only when i disable the second sim.
3G works flawlessly tho.
I guess this is a problem with active dual sims??

Try going to the phones dial pad and enter --: *#*#4636#*#* then select the first option " phone information" and then scroll down till you see the option to choose which type of bands you get or use.
I.e. GSM /LTE auto prl or CDMA/LTE auto, or all of them if global. Just some advise. Also make sure your APNS are correct for your carrier.

How to exclude 2G connections on the Exynos version?

Hi,
In the network menù of my unlocked no brand S9+ with Exynos SOC I can't choose to have only 4G and 3G like in LG devices, do You know if there is some secret code or something like that?
My goal is to have the phone only connect to 3G and 4G networks, and never connect to 2G network
Thanks a lot.

I didn't have that option on my S7 and I don't have it either on my S9. It has only 2 options with "only": 3G and 2G.
But I don't miss that, as my goal is having my phone connected to the best available network. For this "LTE/3G/2G (auto connect)" setting works great.

The problem is that once the phone switch to 2G, it will not be possible to return to 3G or 4G unless you close the call, this means worse voice quality and no data connection until you're stuck in 2G.

There is an app called 4G Switcher that I use to set it to UMTS/LTE only. Try it.

You are technically correct, but the chance of that happening - starting a voice call while only in 2G coverage, moving to a 3G/4G area while still speaking and needing data connection while speaking - is a very long shot. Not to mention that if you force 4G/3G and there is only 2G coverage, then you can't make a voice call at all. So between a lesser quality one and not being able to do it, I'll choose the former.
But my opinions are based on my experience, my destinations and the 4G/3G coverage in my country (Romania). There are extremely rare circumstances where there is no 4G/3G coverage here.

I'm using Vodafone Italy, one of the best mobile operator here in Italy, and when I make a long call, i mean longer than 15 minutes, sooner or later it always got stuck on 2G.
So it is a very annoying behavior, and I can't understand why on a LG phone I can exclude 2G and with a Galaxy S9+ I can't.

Any update on this? It is very annoying e.g. when you're calling inside a car to always go and stay stuck in 2G until the end of the conversation, without data connection working

I want to know this too! I always have better 4G reception than 2G but sometimes it gets stuck to 2G.

up, any update about this?

Yea this app works great. But after January 1st I do believe it will not matter. Since they are doing away with anything lower than 4g

I can confirm that even now, if I start a call under 4G and I'm driving, soon it will switch to 2G, no matter what I do, and I'm using Vodafone Italy, one of the best network here.

Question WiFi Kills Mobile Data

When I have my wifi on, but am not connected to a network, my mobile data does not work either. If I turn off wifi, then the mobile data works. What would cause this? As a 2nd question, Just changed carriers to verizon, what does the 5G symbol look like I'm in Houston and get and LTE+ with little up and down arrows on the side. Is that it?

in addition to the advice provided, make sure that in dev options you enable 'mobile data always active' which should take care of that issue, although without an unlimited data plan you'll max out data quick

5G looks like that on my phone (with a dual sim)
The carrier is Free Telecom in France.

Not seeing the 5G by the bars, but a speed check gives 50mps which is faster than I used to get.

I'm getting the same speed as 4G because my carrier is only deploying on the 700MHz at the moment but in some special places.
I'm not even sure there are already locations in France with Millimeter-wave 5G in France from any of the 4 carriers.
