Turn off 3g completely on Sprint Galaxy tab?

I have a sprint galaxy tab I bought just to use with wifi, but I see cell bars on top and I dont want it using the cell radio at all since I wont ever be using it and need to conserve battery, anyway to shut off completely?
I cant do airplane mode because I need WiFi on

Take the SIM card out of it.
Otherwise turn packet data off & lock the radio to GSM only, uses very little power then.

3G no mas
I have/had the same issue. The other annoying aspect is that if you haven't activated the 3G, it attempts to FOREVER at every boot. I suggest Airplane mode. After you put the tab in Airplane mode, you can manually turn WiFi on, and not have to deal with the search for service you don't want taking up yer juice. That's at least what I did. I know there are other options for rooted tabs, but I'm too scurrrred to root mine...

This will do it.

Wait..that's the jesusfreke verson of bypassing google activation.
He wants to shut off the cell radio.
Try this http://www.google.com/support/forum/p/Android Market/thread?tid=0c985d51aa0b8a23&hl=en
Or this http://www.google.com/support/forum/p/android/thread?tid=1f9a6305673f6eac&hl=en

Uhmm just turn airplane mode on, wiat 5 seconds, then turn wifi on. you're good to go.

some people don't get that the sprint GT is CDMA and don't have neither sim card nor APN.
I'm in the same situation, using the sprint GT as wifi-only in airplane mode.

I tried airplane mode before, but when it killed the wifi (as I expected), I started searching... I had searched all over for this simple procedure with no success until now.
I had recently purchased this Sprint tab under the description of being a wifi only. When I received it and saw that it was a Sprint, I did not care at first, since I live in Canada, until the battery started being drained very quickly in my poor cell reception basement because the CDMA phone could detect a weak cell signal. I know that any other CDMA phone I had would use all its power to latch onto a weak signal.
Thank you very much.

Airplane mode turn off the cellular radios. Sim cards have nothing to do with it. Both GSM and CDMA are affected by airplane mode the same way.
It will turn your device into a wifi tab.

I just select airplane mode then re-select wifi on. This shuts off the 3G but lets you surf wifi.

The problem with the Airplane Mode is that it also turns off Bluetooth. For some reason, unlike wifi Bluetooth can not be turned back on individually while airplane mode is selected. Any ideas anyone???

I FOUND THE ANSWER!!!!! EasySwitch Pro
This is a fabulous app that allows COMPLETE and SEPARATE control of your wireless radios.
EasySwitch Pro by SMARTDYNE
Uses a very simple and effective widget to switch settings.
Works great on Samsung Galaxy Tab!!!
Here's the link:

I'm not on my tab at the moment so I will do it from memory. For the data issue, if you hold down power, you will see a selection above airplane mode about something to do with data. Turn that off. When I was playing around with it I'm the past, you need to have the radio on (not airplane mode) in order for the GPS to lock. You can also, In settings, enable network location in the location section.
To get rid of the activation nag, note the icon in the notifications bar. See what it looks like? I used root explorer, rooted of course, to navigate to /system/app. Scroll down slowly until you see an apk that has the same green circle with a check mark inside it. Enter rw mode with root explorer. Add .old to the end of the filename. Reboot. No more nag. If you delete it, you cannot update to gingerbread. It needs to be running to get the update. You can disable it later. You also lose all update functions in the about my galaxy tab section.

I use Widgetsoid2.x it allows me to go airplane, enable/disable 3G, wifi, GPS and more. Can get it in Market.

Sigh, you have it wrong. Turn on Airplane mode, go back into Settings and turn on WiFi and Bluetooth. Simple as that.
The ONLY way you can't turn on Bluetooth in Airplane mode is from the drop down slider thingy in Android. If you go into Settings, you can turn on Bluetooth in Airplane mode.

whats up?
Still wishin to kill cell-radio-app =) Any new ideas except the airplane mode?
ps:GPS and Bluetooth don't work in this mode..

I tried selecting airplane mode and then turning back on WiFi. However, Galaxy Tab is still trying to activate the Sprint account I do not have or want to get.

use titanium.

i use titanium backup pro... open titanium press "backup/restore" tab and look for the icon as appear on status bar, the app name is "System Updates 1.0.0" press and hit "Freeze !" this gonna stop the app to work is better than deleted dont delete it, you may need it later, then reboot. Sprint Activate message disappear on my tab. You must be rooted to use titanium app.

Wifi does not auto-connect when screen is off

I have a wifi issue that is a little different from other I have read here.
Issue: When my phone screen is off, it will NOT auto-connect to saved Wifi hotspots (eg, home, office) within range, until I wake up the phone (turn on the screen).
When it is connected to the Wifi hotspot, it will keep the connections even when the screen is off. (non issue)
I have set "Keep Wifi on during Sleep" to Always, and set "Sleep mode" to off. "Power Saver" is off too. Mobile data is off (I turn it on only when I need it). I checked battery usage, and Wifi is constantly on, just that it does not connected to the saved Wifi.
My question/issue is, is it normal for the One to not auto-connect to saved Wifi hotspots within range when the screen is off?
On my old HTC EVO 3D running ICS, it will automatically connect to the same hotspots without the need to wake up the phone (turn on the screen).
My One is still using the stock Rogers firmware (1.29.631.4)
UPDATE: I found that this appears to happen only when the screen has been off for a longer time (more than a couple hours). If I have waken the screen up an hour before it entered the saved wifi range, then it seems to auto-connect fine. Need more testings.

I do believe it is normal. It's to conserve power your phone would have to have a wakelock to connect to another network draining power. As I understand it the ONE puts the wifi into a power saving mode when it's not connected so it's not constantly draining your power while driving. Once you wake the screen it will then connect as it assumes you want it.

Should that be an option to turn that off, such as the "Wifi Sleep Policy" I saw from some other rom? Or the settings I mentioned above disable that behaviour already?

Don't think so. The wifi sleep would turn the wifi radio off which isn't happening. Oh quick thought check the network and make sure the phone is set to auto connect that would do it for sure!

Nevermind isn't there. Maybe I'm thinking of stock android or maybe I'm thinking of another OS.

Can anyone else confirm if this behaviour is normal or not?
So if I don't wake my screen, I will never get any sync when the screen is off and I just get back into wifi range?

Go into WiFi Settings, Go to the menu and click Advanced. Change "Keep Wi-Fi on during sleep" to "Always".
WiFi will connect with screen off.

As I have indicated in my first post, this has been set to "Always" already. Are you sure that works for you?

What is the phone not doing that you want it to do? Just turn on auto sync if you want your email and FB updates to be waiting for you. Or is that not working?

Quick test. Put your phone to sleep with gmail autosync push mail on. Turn off data and only enable WiFi. Then send yourself an email from a computer, if you get a notification on your phone while it is sleeping, then it is working. Or you can place a voip call with viber or send yourself a viber text from another phone.

It is not auto connecting to the saved Wifi networks when I go to work, or when I go home, with the screen off. I have to wake the phone (press the power button) and you can see that it will connect to the saved Wifi networks. The FB notifications and Whatsapp notifications are pushed, so they don't require auto-sync to be on.

If my phone is already connected to the Wifi networks, putting it to sleep will NOT disconnect it from the Wifi network. It only happens when I changed from one saved network to another (home to work, or work to home) with the screen off, then it will not auto-connect. I have tested that and I'm not getting the notification in that situations. I have to wake the phone up to trigger the auto-connect.

Is your wifi toggle always on? Or do you turn it off once you leave a certain network? The only way the device will auto connect to a saved network, is if the wifi toggle is already turned on before you go near a saved wifi network.
If you want a saved network to automatically turn on wifi and connect to a saved network, you will need some thing like juice defender. It teaches itself to know when you're near a saved wifi network and it will automatically turn on your wifi toggle on and connect to the saved network. Then once you leave the area or lock your device, it will automatically toggle off wifi and disconnect from the wifi network.

Not sure what you mean by "wifi toggle always on". My Wifi (under setting) on the phone is always on. I never turned it off. Under Power History, I can also see that Wifi is always on (un-interrupted blue bar).

I contacted HTC support, and they asked me to change the WiFi band frequency from "Auto" to "2.4GHz" and reboot the phone. It seems to have fixed the problem so far (after a couple days of testing). Although it would have been nice if they can fixed the problem properly.

Yeah, I just got the One almost a month ago and seriously thinking of returning it because of this issue. I wish I wouldn't have rooted it because since I did for some reason I can't get ADB to recognize my device. I've tried everything my noob brain can think of to fix it and the wifi issue but nothing works. I see that no other developers have a fix either as no apps or threads here give a solid solution.
I might give AT&T the money to warranty it and just get another device but I want that to be my last resort.
Personally, I think it might be an isolated hardware defect that was addressed with later devices which is why it is not as wide spread and therefore doesn't generate a need to find a workable solution.

Not sure if I have been using the phone more, or if I have flash new radio (Radio from 2.17 base - 4A.16.3250.24_10.38.1150.03L (flashable Zip) and rom (ARHD), I don't think I have this problem any more.

No, I believe you have to be S-Off to do that, or else you need to flash the firmware. Have you trying reinstalling drivers or try on another computer to get ADB to recognise your phone?

How do I unlink a Droid from the carrier?

I have an original Verizon Droid that has been out of service a long time. I'm recommissioning it as a music player for my wife to take to the gym. But when I fire it up, it still thinks it should be an active phone, and Verizon thinks so too; it connects to Verizon's network and is able to make calls.
Right now I have it on Airplane Mode to prevent this, but that disables wi-fi too, and I want it to have wi-fi. Is there a way to erase or reset whatever configuration the carrier gave it, so that it will not try to connect, or at least will not succeed? It's running Cyanogenmod 7, if that makes a difference.

Turn of wi-fi after you turned on Airplane Mode.

No, I want wi-fi ON, not off. I just don't want it connecting to a carrier.

1) Turn Airplane Mode ON (yes, I know this will turn Wi-Fi off)
2) Turn Wi-Fi ON (Wi-Fi will turn on while the mobile connection stays disabled)

[Q] Why am seeing network signal strength & Cellular Radios on in Airplane Mode?

So I am using a Nexus 6 on the Latest Tmo build (28E?) of Stock Rom and Stock Kernel Rooted, Encrypted.
Since the update that enabled wifi-calling for the N6 I have taken to setting my phone to airplane mode and turning on Wifi only to save battery since the signal at my house bounces back and forth from LTE to 3G and that murders my battery. Most of the time the signal strength graph shows blank and battery app correctly shows the cellular radios as having no on time. However, after being idle for a while (it would seem) the graph begins to show the signal strength as Red (no signal) and the cellular standby shows up in battery usage with the radios as being on (with no signal) and "active for a few seconds". Toggling airplane mode on and off usually restores them to showing up as off. Other times I never notice and it stays on for a few hours and goes back off on it's own. My main concern is that it seems to be activating the radio on it's own, my minor concern would be that my battery monitor app shows that it's using the battery. What could be causing this? I don't think it's a reporting glitch, because it shows up in both the system battery panel and a 3rd party one. If anyone has any thoughts or could point me towards a tool that could help me figure out what's turning on the radio when it's supposed to be off, please let me know. I've included photos from today showing what I'm talking about, the phone has been in airplane mode the whole time in these photos.
Thanks so much!
Kev

I think your issue is one of the reason why I cannot get Wifi Calling working at all. No matter what I do, my phone is holding onto a cellular network. Still trying to figure this out.

The best I can tell, "Android OS" is the only thing that shows any mobile packets sent or received so it's got to be a system thing.

If you have the myT-mobile app installed try uninstalling it I found that app totally screwed with my Nexus 6, turning WiFi on when I had no desire to use it.

Unfortunately that's not the fix. I don't have that app installed. Tmo is sending me a new SIM as I am also randomly having Wifi calling drop in and out even while my wifi is connected.
Does anyone know any app that would let me see specifically what app is engaging the mobile radio?

Why is Airplane Mode off on settings but on on Service Mode? [solved]

I've been having trouble connecting to the tmobile network. I can do it through wifi and make call through wifi-calling. But when I'm out it says network not available.
When I reboot the phone I manage to connect for a few seconds and then I lose it. Tried the Airplane Mode on and off thing but it didn't help.
When I go to *#0011# I get <No SVC> but when I went go to *#2263# it says that Airplane Mode is ON and that I need to turn it off to access that menu. Since Airplane mode is already off under settings then that's as far as i can go.
With my quick wit I thought, hey that's probably why I don't have any network connection, because the Stealth Airplane Mode is ON
So, what could be causing this dichotomy in between the service mode and the settings? Could it be that the ServiceMode is "concluding" that Airplane Mode is ON, but the problem is actually somewhere else? Like when Windows "help" tries to guess your problem but strikes out badly.
Is there another place that I can turn the Airplane Mode off, a different service code or some misbehaving google app?
On top of that, I got two s6 with problems. Most of the wifey's sensors are shot. But she can make phone calls so her problems will be dealt after mine. The funny stuff is that both started cranking out at about the same time, so unless this was a warranty time bomb, maybe our wireless chargers have something to do with it. Or not and I'm just being horribly unlucky right now, which is always a safe statement to make.
Anyone know how to turn Airplane Mode off besides Settings/AirplaneMode or the slide down thingy?
No Power Saving mode is enabled (but that doesn't mean nothing at this point).
Thanks

Sunofa whore... I been dealing with this **** all day. Then right after I posted here I decided to go look at all the menus in the Network area. And sure enough, under wifi-calling it was marked to "never use cellular network". This self changing selections on Android drives crazy. Thanks for thinking about helping me. Maybe I can find a setting on my wife's phone saying to disable all sensors....
