I usually used wifi at home/ company, rarely use 3G, so I used to turn it off by using APNdroid.
Today I needed to search something online so I turned my 3G on by using APNdroid. The 3G icon didn't show up. It didn't work even I switched on the "data roaming" in setting, reboot, switch to airplane mode then switch back.....
Anybody can give me some advice?
I'll second this for the battery savings

With APNDroid in the "on" mode, check your APN settings in Wireless Settings > Moblie Networks > Access Point Names. If there is nothing there, try Menu > Restore Defaults.

Try to flash a phone if you do not help means that the operator, or reset settings
Do you have the correct APN (Access Point Name) set for your network operator?
Some apps that allow you to turn data on/off rename the APN from for example:
internet to _disabled_internet.
If you use the app to switch it off then uninstall the app, it leaves the APN with the wrong name.
Do you have the these settings as follows:
Settings > Wireless & network settings > Mobile Networks > Data enabled = True
> Use only 2G networks = False
Yes i think that i have the correct apn .

I had a similar roaming prompt when running Sprint-based ROMs on my wife s Incredible. The solution was to deactivate the phone guard in system settings.
I noticed a similar function on our S3's under Data Usage>More Settings>Roaming>Roaming Guard. Maybe tinker with these settings?
Thought I'd throw it out there ...

I'm on CM10 at the moment with the roaming issue, ill restore a nandroid of stock and see if this helps
That would be cool ... I'm really curious to see if this will work.

Ill try it with my dad's phone in a few minutes and see if it makes a difference.
I can't find this roaming guard option, all I see under Data Usage is Mobile Data checkbox, Limit Mobile data usage checkbox, alert me about data usage checkbox, data roaming checkbox, restrict background data checkbox, and show Wi-Fi usage checkbox. I also looked at any cut and could not find anything

Whatever you do don't mess with the Roaming Guard settings...
I found the Roaming Guard settings under the second data roaming option in any cut and not sure what I did but I actually lost all service on my phone and even enabling data roaming again in the system settings would not get roaming to turn back on, I had no text, calls, or data and under about phone it said I was not roaming nor was I connected to any networks. I tried all combinations of settings in Roaming Guard and nothing would get it to restore roaming until I dialed *2767*3855# to re-provision my phone. Not even restoring a nandroid worked, only the re-provision. Sorry bro, thanks for trying at least

Don't know what you did - or what ROM you were on when you did it - but I've changed these settings to and fro with no ill effect.

aaa my bad, I was looking under data usage like the OP stated (Data Usage>Other Settings>Roaming Guard) what I did that caused me to lose all roaming abilities was creating a easy cut shortcut to data roaming and in that setting there was "Roaming Guard" in there the option of automatic and sprint only roaming, I selected automatic and instantly all roaming was lost, I'll restore my nandroid and try Settings -> More Settings -> Roaming -> Roaming Guard
I checked mine and it is set to automatic by default ...

Mine was not on automatic by default nothing was selected that might be caused by the roaming issue
Hmmmm ...
Did you try unchecking voice and data under Roaming Guard?

My S4 One S automatically tends to switch to a 3G connection when its idle, and when i begin using it, it sends its data upload thru the 3G connection, WAITS to switch to HSDPA, and then pulls in incoming data. There is no incoming data on the 3G connection at all. Only on HSDPA.
I have googled enough, found this error on many devices, but I cant seem to find a fix.
Is there any way to completely switch to HSDPA to avoid the delay it takes to switch to HSDPA?
Or is there any way to make it receive data as well on the 3G connection?
I am using Android 4.0.4 on a Vodafone India connection in Chennai.
i believe if u disable "fast dormancy" then youll be able to switch and stay connected to HSPA... altho fast dormancy does help save battery if your carrier supports it
And how do i do that?

Anyone, please ?
You can edit your build prop file with es explorer or if your on a Rom like viper there is an option in tweaks

So when the phone boots up, I have 4G connectivity. When I decide to turn on my Wi-Fi, use it for a little bit and then turn it off...I don't have any data. Data is on and I try toggling airplane mode as well. I just have bars for calls and sms. No data for surfing the web and etc.
Has anyone gone through this?
Happens on other ROMs for me as well.
What are your settings under mobile network settings network mode, system select and CDMA subscription?
