how do i stop my 9100 from connecting to 3g - Galaxy S II Q&A, Help & Troubleshooting

phone setup:
i9100
android ver 4.0.3
baseband i9100mugld3
cf rooted
This may sound like a crazy question but there are 2 locations i'm at a lot that have 0 to 1 bars of 3g and an edge tower right on top of them. Anyway for some reason the phone almost always wants to grab onto the 3g and it is a horrible connection for both voice and data. I have wireless there so i really don't care about data but dropping calls sucks. Is there an app, solution, workaround to forcing the phone onto the cel tower i want to use instead of letting it decide to do the wrong thing?
thanks

Have you tried just turning off mobile data in settings?

Settings > Wireless & Network > More > Mobile Network > Network mode > select GSM only and it will only use the gprs connection. If you dont want to use the GPRS connection then uncheck the " Use Packet Data Option ".

I've actually tried that while it disables data it doesn't force a switch on the tower. I guess my title & original question isn't quite right.
so now i guess how do i force my phone onto a different tower so i can actually get good service when i need it.

I just use the switchpro widget, since then i can turn on and off a lot of stuff from my homescreen.

Under mobile network settings, change it from auto mode to gsm only. I guess this is what you are looking for

actually i was just about to post the gsm/wcdma/auto to get it to switch over. However it does not always work sadly. I remember on an old moto (forget model) that i could actually choose a network tower, man i wish i could do that now

It perfectly works for me. If i set gsm only, it stays on edge and if i set wcdma only, it stays on H+ for me.

sorry should have been more specific again. it will go to edge but will often decide to pick a tower far away instead of a close one

[ISSUE] How to prefer Wi-Fi to 3G

I have a HTC Fuze. The last few ROMS that i have been using (Energy, RRE, Tael), all the Apps always use the 3G internet to do their work even if a much faster Wifi is connected. Is there any way to make all apps(including things like email) globally prefer the Wifi when available? Also I dont want to have to keep changing settings to do this, It simply needs to be "If Wifi available use it, else use 3G"
Thanks in advance.
What i did was to go to start>settings>connections>advanced>select networks and change the default connection to the internet to "My work network", rather than my 3G network. This way, if theres any connection to the internet needed, my phone will use my wifi connection. The problem with this, however, is that when you dont have a wifi connection available, the phone will not connect to the internet unless you change the above setting back to your 3G network. If anyone knows a better way, please let us know
no i cant keep switching. thats too much trouble. there must be a better way.

Does it automatically connect to WiFi when a known network is within range even when the phone is in sleep? If yes, does it disconnect once not in use for a while?

As far as I know there is no way to do it automatically. You can use one or the other but they must be switched manually. All HTC phones have always worked this way. Maybe if the demand was high enough which apparently it is not a Chef could come up with an app that would do it. But for now you must do it manually.

that is extremely failurous. not preferring the fastest internet connection is major fail. did not know that.
My phone does this automatically. It uses the WiFi whenever it's on. If the WiFi is off, it uses the data connection.
Maybe I'm understanding it wrong?

what the heck? how? u must help me find out..
i think it does prefer wifi over 3g in WM 6.5...!!
to check it out here is wt i've done....turn data connection off...check that its on in the notification manager "when u click on the task bar"..then run any app that needs internet " opera, msn messenger, email...etc" while this app is online..
now there r two ways to check it
1-the notification manager & see if it turned to 3g data connection...if so u should find a timer running in ur service provider section, if not then its only using wifi
2-check the communication manager & see if it turned the data connection on, if its off then its using wifi...
thats how it is with my touch pro...i'm using energy rom nov. 08 build
Indeed it prefers wifi connections 2 data, but You have to :
1. Have Known wifi spots in range
2. Keep wifi connection on, while in stand by
Keep in mind that if a program starts to use the data connection it wont change to use the wifi one. So firstly connect and then open programs.

apparently its some sort of combo of this. i am using 6.5. any apps that have been using 3g continue with it. and i have to go to the comm screen and turn off data to force new apps to consume wifi. which isnt too bad, certainly not as bad as going to the network options. i would wish they made this a bit more seamless like with the desktop technology, i can switch from wired to wireless lan without even dropping a skype call.

now i have discovered a new problem. even if i open the app after i have wifi turned on and data turned off, some apps just dont want to use the wifii.
Bing maps and google maps for example just tell me there is no internet.
this is really pissing me off, whats the point of having wifi on a phone if the apps wont use it. i dont really care about the google location service if the data is through the internet, but atleast turn on.
lame.

[Q] How to disable 3G/UMTS and use only EDGE

How can I disable 3G and only use EDGE for Internet Connections?
Maybe it safes some battery as mine sucks like hell... even more than my (old) iPhone4 which I try to replace but I am not yet convinced by this phone and OS yet...
I havent found it too ..
on android phones its in main settings, wireless and networks, then hit the use 2g only checkbox.
Go to Settings/Wireless Network/Mobile Network/Network Mode/ Select GSM ONLY.
That will get you 2g data. Hit the thanks button if it helps.

Used to have 3G but it doesn't work anymore.

Hi,
I own a sgs2 running the latest CM10 rom by codeworks.
My phone all worked fine until 1 week ago, when out of the blue I lost 3G connection. I still run Edge just fine.
I run on the giffgaff network in the UK. I checked all my APN settings 5000 times, played around with them, resetted them, doesn't help.
There is no coverage issue in my area (I traveled around London anyway). I have the right plan.
I used someone else's SIM card with a data plan, it didn't help either.
I flashed a different modem (LPS), didn't help.
I google'd a bunch of stuff that didn't help at all basically.
I would understand if I didn't have any data connection at all, but I can get Edge just fine and browse the internet/download, it's just painfully slow.
Does anyone have an idea about how to fix my issue? I'll literarily take every piece of advice right now.
Thanks,
Gary

Solution:
1. Goto Settings
2. Under wireless & network, select more
3. Select mobile networks
4. Disable data connection, wait for 5mins
5. Uncheck use only 2G networks
6. Enable data connection
Problem should be solved now

How to use 3G data connection same time wifi?

I have a technical question ... you can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?
Simply put no. Phones are not made to use 2 different wireless signals at once.
Bat cave One
The only way to use both is setting a Wi-FI access point on your phone. Still, you can't do things you want to: PC connects to smartphone just to get internet data.
No there is no way around it.

Do you even understand what your asking? Voice and data are 2 very different things. Data and call signals are handled by different process. The antenna are set to do one voice and one data. Think about it. Even dual sim card devices can only use one at a time.
Bat cave One
Yes I understand ... so it is not technically possible to manage wifi and 3g antenna at the same time because data can only handle one job at a time? I thought the wifi module and the module 3g were managed separately...
This is an android software limitations?
When you use the wifi 3g module is put into the off state to save battery, works only the incall module. When you disable the wifi 3g module change the status to up. About your question no, it's impossible to use wifi and 3g at the same time to make 2 different operation

thanks for the reply. just in my office I have a wifi router with no internet connection, are connected with the phone to surf the intranet. so I would keep the connection 3g to receive notifications from whattsup or other ... every time without having to turn off and on the wifi. It does not seem like a stupid question.
This is not directly related to your problem but using wifi and mobile data at the same time seems to be possible: http://forum.xda-developers.com/showthread.php?t=1667025
Tank you, i see that... But you can only download a file....
I read of a change made to the file system / framework / services.jar
But i don't know if it work....

That's incorrect. Android phones can use multiple wireless signals at once (wifi, cell, mobile data, bluetooth, nfc). And they can have multiple network interfaces up at the same time just like any linux box can. It just happens that the network manager turns of mobile data when you turn on wifi, but that's on purpose (to save you battery/cost), and not because the phone isn't capable of it.
Not sure why you say with such authority there's no way around it. If you don't know the answer to something for sure, better don't give a wrong answer.
There's even an app on the play store that can loadbalance a download over wifi and mobile data at the same time:

I say this from past experience that the WiFi antenna could not get a signal at the same time as the data antenna.
Now while this may have changed. I will look into it myself before I pay much heed to it as anything more then smoke and mirrors.

4G stays on when connected to WiFi?

Why does the 4G stay on when connected to WiFi, it does not seem to be using any data but wouldn't it save battery if it turned the 4G off when not in use? I used to have sprint and mobile data always automatically turned off when on WiFi, this is my first verizon phone, is this normal on all verizon devices?

As long as the 4G icon is greyed out it's disconnected. It's just in a ready state in case of sending or receiving mms when it will turn white with activity arrows
Hello, This is a problem on many devices. The best way to fix it is too go to Settings, Wireless Settings, Mobile Settings and then turn off your data.

If you turn data off you will not be able to receive or send mms. Best to leave it alone. I use g3 teeakbox to hide it when on Wi-Fi
For phone calls and text messages. Data will go through wifi.

I hear you - if the 4g radio is on it is theoretically eating your battery; although it may be negligible with the power saving built into the phone. If you want 4g/data completely off while on WiFi you can download a tasker app from the play store and set it up to automatically switch off data when WiFi is connected & vice versa; it's been working well for me. You'll lose stock MMS if data is turned off though, so consider that before you use a tasker. You can always grab a 3rd party messaging app for MMS if you need it, and they will work because they are only over WiFi.
But if it is just an aesthetic thing, as mentioned in a post above, you can hide the icon using g3 tweaks.
The only difference is that these phones show you what mobile data connection you have. On T-Mobile, you may have a phone that only shows the bars when on WiFi, but it's still connected, just look at an app like Signal Check Pro.
This is not eating your battery, it's not being used, it simply tells you what connection is idle for when you are no longer using WiFi.
