Turn off 3g?

Anyway to turn off 3g in our cdma phones. Might save a lot of battery.

turn off "mobile network" and just use wifi at home?

I've read that the phone constantly searching for 3G and/or using 3G is a big battery drain. Also that unless you require the bandwidth you can do just fine with 2g. There are apps on the market to let you switch 3g off but the ones I found don't work with cdma phones.

Turning mobile network off like said above will turn off 3g...

Doesn't it turn off 2G or edge also. I want data when I don't have wifi. I also thought the phone switched off mobile network when connects wifi automatically.

If you hold the power button and turn off mobile network it turns off 3g. It goes to 1x and you basically receive text and phone calls..it helps turning it off in my house because I don't get great reception so its not always looking for that 3g

Thanks. Is that only 1G? That's partially what I want. Better would be to be able to get 2G which would be ok for web browsing. 1x is painfully slow and useless. I'd like to be able to switch to 3x just for streaming video, downloading, or other high data needs.

Yes.
Hold power down.
I think ATT when you turn off 3g it goes to 2g.but if um not using 3g I keep it in 1x

If you still have sense, there is a widget from the settings that you can add to do this instead of having to hit the power button. Make it a 1 step process!

So it is not possible to shut off 3G and keep 2G?

analog = 1Gen network
1X = 2Gen network
EVDO = 3Gen network
EDGE is GSM 2G, does not apply to this discussion.

No.
An easy way to see what you can and can't do is to install the HTC Widgets (found under "Widgets", then "Settings").
The one's relevant to the topic are:
Mobile Network and Wi-Fi.
I also use Bluetooth and GPS widgets, and between the four, manage battery consumption as best I can depending upon what I'm doing and whether or not I have wi-fi coverage available. If I'm just doing calls and SMS text messaging, I turn them all off.

OK. Thanks all

Incredible. The OP is looking for wireless data (see his post #5) when 3G is off. If you can do that, post a how-to. When I disable 3G and wi-fi, I get 1x - which is 2G, as explained - but isn't what the OP is trying to ask for (but getting terminology mixed up).

[Q] data lost while on call

when i am on a call i cant not see to get data...the data connection turns off by itself and when the call ends data connection will come back on? is it suppose to be like that or is there something wrong with the phone. right now im on software 1.28.708.10. thanks

Happens to me too I believe my frined.
It only happens with mobile data though.
If you are on Wifi, the wifi should NOT disconnect right?

ya if it is on wifi then it is ok. not data connection though

I believe that the phone switches to 2g during calls, and not sure whether this is a telco setting that they do not allow calls through 3g, or a software feature of the phone with the reasoning that 2g signals are generally stronger in most parts of the world compared to 3g.

Just fyi i had the same issue on my "old" Desire HD.

It might be carrier specific. I have no trouble getting (and keeping) HSPA data when I'm in a call.

which version do u have Barry? I am using the international version on rogers. Are you using the at&t version?

Then I believe it to be carrier specific then since the software governing these kinda things should be standard across the board

A UK international version on AT&T.

Ok that is so strange. I have the Hong kong version on rogers network. It never happened to me before and I have used a lot of HTC and unlocked phones before.

ok so i dont think its the carrier cuz i reset the phone and it works sometimes now. if i make a call and browse right away then it will work but if i leave it for too long then it wont work.

guys its because the phone calls you make are on a 2g bandwidth unless its a video call, that's why if you have 2g connection or EDGE active it will get disabled as soon as you make a call.
to clarify, force your network settings to wcdma and then connect to 3g, after that make a call and your 3g will not be disconnected

Hi Marktang... I saw your post from Google as I lost data connection during phone call with my Galaxy S2.
May I know is it after configure the Network Mode inside the setting to use WCDMA only, then the problem will be solved?
Thank you...

Where did my 4G go!

I live in area that does not have 4 g so it stays off, however today at airport I tried and no 4G toggle anywhere! Where did it go, I swore when I got s3 I tested 4G but now it's gone? Thanks for help.

GS3 doent have a 4g "toggle" as you say...but you can make sure its enabled
settings-->more settings-->Mobile Network-->Network mode.
Preferred network mode should be set to "CDMA/LTE/EVDO"
If you have "CDMA/LTE/EVDO" enabled, anytime your in a Sprint LTE area your phone icon will switch from 3g to 4g.

it shouldnt chew up ure bttery at all, as all it does is search the network for 4gLTE and if it doesnt find it, it will automaticly go to sleep and try again like 2 or 3 hours later or periodically as it tells u. .however u do need to have sprint automatic connention left on in order for that work. atleast thats what i got from reading the sprint connection optimizer information it gave me.

The optimizer isn't for the LTE. I hate that garbage so I always leave it off. As long as your preferred network is set as stated above, it will automatically switch between them. Side note though, it may switch back to 3g if you don't have a very strong 4 g signal. It likes to be weird.

Sounds like your thinking of a wimax phone. I I had a Motorola Photon and you had to physically turn 4g on and off on it.... I think most wimax 4g phones are that way.
Sent from my SPH-L710 using xda app-developers app

Do any of the custom ROMS have a toggle for 4g/3g? I live in a 4g area but sometimes the signal isn't strong enough so it goes to 3g. Quite annoying. It would be great to toggle 3g off and force 4g.

So I had s2 before s3, so I assume the s2 was a 4 -g wimax? It had a toggle widget.

Have you tried updating to the new radio? I believe they boosted the power to give slightly better LTE connectivity in those kinds of environments.

There is a way to force LTE on the GS3. I did it with mine so that I could map out the LTE zones with sensorly a bit easier while I was driving over the weekend. The way I was able to do this is you need to have Nova Launcher downloaded and installed.
Once you do this, long press on the home screen and go to "Shortcuts".
Next click on "Activities"
Next scroll down to "IOTHiddenMenu"
Then scroll down and click on "IOTHiddenMenu : HDR1X_Selection"
Doing this will allow you to force LTE only mode. Keep in mind you WILL NOT be able to make any phone calls while doing this. For some reason the GS3 requires the phone to be in LTE + CDMA + EVDO Mode to make calls even if you have a very strong LTE signal.
Another app I would recommend downloading is called OpenSignalMaps. Once you have the LTE only mode turned on or even the normal LTE + CDMA mode, you can use this app to refresh your network by clicking the little refresh button at the bottom left of the app in the Overview tab. What this does is pretty much turn your phones mobile networks on and off and then scan for LTE first before scanning for EVDO. I have been able to connect to many more LTE sites by doing this. Even ones that are fairly far away.
Hope this all helps. Let me know if you have any extra questions.

No data connection at all
I have the settings on GSM/HSPA/LTE, but lost data connection completely. Tried to restart and turned on/off flight mode - still no data. Voice in and out is OK. I finally managed to reconnect by repeating the process. Is there a better way to reconnect?
Thanks.

Check out "Network"

with the latest l13 radio my phone will not stay on 4g it is heavily biased to 3g and I do not know how to fix it. I am right next to the 4g towers.. ... any thoughts? Thanks

Thanks
Thanks. Unfortunately, the "Network" app would not run. So I followed a similar line, and found "3G Reconnect". It does not fix the connection issue. Any other thoughts?

Data connection lost

I been having this issue since I loaded up wicked rom on my phone. Works for 5 minutes only then loose connection, the only way seem to get connected again is through making a phone call to any... I just call my voicemail to get connected again so I don't have to annoy people! Help!!!

The current modem seems to *really* want to be on LTE. If you don't care about LTE you can disable it...settings - connections tab - more networks - mobile networks - change "Network Mode" to GSM/WCDMA. You'll still get HSPA+ speeds, but it should stay connected better.

Thanks man, it's just weird that the only way to get back connected is to make a phone call... I was at the time bike store yesterday and they mentioned something about updating the towers to LTE and should be over end of this summer... They said they are already ahead of sprint as in service at the moment and they are trying to be on the same page as AT&T and Verizon. I messed with the option by the way many times but didn't notice the difference yet but I will update the result on a following reply in the future. Thanks again

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?

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.
