Tasker (or Locale / SetProfiles): Automatically switch to 2G only

Goal: Automatically switch to Use only 2G networks without opening Mobile Networks Settings dialog and checking the box manually
I know that this is not possible on stock, but is there any way to accomplish this for root users or with any of the mentioned apps or otherwise:
I do not want to disable APN, and I've already used APNdroid to much dismay. There is a bug for Nexus One users when restoring APN settings that leaves mobile data disabled.
I've used the apps mentioned in the thread title to automate my phones settings (ringer volume, GPS on/off, bluetooth on when phone ringing, data syncing, etc.), and now I simply want to disable 3G radio connection whenever certain conditions are met and have my network type as "GSM only"
I've searched through different forums here and sorted through a litany of Google search results, so please no lmgtfy because "2G only" returns no results in this section and no relevant results elsewhere; "2g only auto" nothing; "2g only automatic" nothing, but you can flame if you post a solution

If you don't mind me asking - what is the reason for it? When you switch WiFi on, the data is turned off anyway. So why?

Yes, when your device is connected to WiFi the GPRS service for data is disabled. However, the 3G band radio in your phone is still being used which consumes more power than the global GSM band radio that is used when connected to the EDGE network type. This is always true whether you are connected to WiFi or not. (correct me if I'm wrong)
Regardless, the answer to this would help a lot of android users. This is not specifically tailored for me, because the entire OP relates to battery performance which should be an important issue for all Nexus One users. If this task could be automated it would dramatically improve battery performance during off-peak use (nighttime, work, meetings, etc.) by improving execution and eliminating forgetfulness. Automating this adds to the user experience and would just make your phone that much more enjoyable, period.
I'm simply amazed that I can't find a resolution to accomplishing this.

The cellular standby / talk time power doesn't vary much between GSM and UMTS, the difference is less than ~20% in both modes in case of Nexus, judging by official specs. I'll check your assumption that UMTS connectivity isn't dropped to GSM when WiFi connects (most probably correct), but the power gain isn't significant in places that have proper UMTS connectivity (which is not the case for the whole world, I know).
The easiest way I can think of would be to use SwitchPro widget, for example (or any other free widget that has the same functionality), and instead of pressing only "WiFi On" button, press 2 buttons - "WiFi On" and "2G/3G connection" (the same as pressing the "Use 2G networks only" checkbox).
I would suppose that such a plug-in or setting might be available for Locale/Profiles/etc.

2 things that I've found:
1) The connection indeed stays UMTS.
2) Android system prevents the programs from toggling 2G/3G mode, it's only allowed manually. The widgets I've seen only take you to the correct Settings submenu, but you have to click the checkbox yourself.

Thank you Jack_R1,
I appreciate the replies and the confirmation. That is the conlussion that I have been stuck with for a while. I had assumed that there may be a way to control this with superuser permissions.
I guess I'm going to have to dust off my Java, contact some app developers, and start exploring how to come up with a solution myself.
I apreciate your feedback.

You're welcome.
I suppose that this thread might be useful:

What you're looking for might also be one of the lower level system functions, requiring system permissions, not only root.
Might be worth contacting Cyanogen's team or Enomther, to make an option for it on ROM level and incorporate in the next AOSP-based ROMs.

Thanks again. That post helped. The settings are not accessible in the current framework. When I get enough time this week I think I can start on getting this fixed for root users. I will take your advice and will contact some of the masters here who would know the libraries well.

in addition, one scenario could be:
At home, I do have pretty poor 3G connection with my service provider, so I would like to switch when I am near my WiFi to 2G mode

And ditto again.

I have the same desire as the op. It must be possible to do since one can easily toggle 2G/3G from the power control widget in cm6. Maybe if there was an intent that was published tasker should be able to launch an app with that intent to accomplish this.

on a recent trip overseas, I was presented with a very weird situation. I bought a local sim and got a 3g data plan which was 3gb of 3g data and 200mb of 2g data (dont ask i have no idea why they are different). When I plugged it in i could do 3g data no problem but if 3g was turned on i could not make or receive calls. so like the op I wanted an automated way of switching between 2g only and 3g
I was able to do it on my nexus one and tasker with
Toggle 2G/3G
hope this helps you

^ +1 best toggle I've seen and used.

Issue with WiFi calling?

On my notifications, it says that WiFi calling is turned on, but the cellular bars are still on. On the last Samsung phone i owned, the cellular bars were kind of disabled and it only showed the WiFi bars.
Is this how it loooks for you guys?

Same here, the bars never go grey........I thought this might result from the wonders of smartswitch allowing you to pick your call where wifi falls away however even disabling it doesnt change the colour!! Do you think that this means the cellular radio is actually still active or is just a little bit of superficial window-dressing that T-mobile will change with an update?!

As long as you see the handset/with the wifi symbol above, means you are using wifi calling. That goes away when it switches to cell tower calling. If you prefer wifi calling, then make your setting as the image below.

If u put like picture you will have wifi calling fully and not be using network if you put on the middle it will show like urs wifi calling amd also using network meaning it will show the bars

I have no doubt i am using WiFi calling.
BUT, i think the question still stands, why is the mobile network still on? And is there a way to turn it off?
On my S5 it would turn off. As a result, i assume battery life increased.

I have a weird issue with wifi calling..
If I have it turned on, and I leave the house, I have no access to my data network as I travel around my area; I think the issue is that its always looking for wifi networks, and there are so many of them around me, including xfinity hot spots that are transmitting from people's homes, that I can't make phone calls easily.
Turning off wifi calling gets things back to normal, but I would like to leave "wifi calling preferred" on all the time, but it doesnt seem to be working properly..
This is in Chicagoland, where we have VOLTE, and all the "newest" Tmobile stuff active.
Anyone else notice this?

The bars are on because the Note 4 is a dual-mode device and can stay connected to both IWLAN (WiFi Calling) and cellular networks simultaneously so you can do seamless handoff from one to the other (VoLTE only). This is in contrast to previous Samsung phones that could only do one or the other. This is perfectly normal behavior.

Yeah, the only other phone that does it on T-Mobile is the iPhone 6. I actually love this feature cause often time I'll be on a WiFi call and forget and then drive out from my home and the call would just drop.

Disconnecting WiFi

Hello,
I've used my Mi A2 around 2 weeks now and I'm really satisfied with the phone. However, I got some annoying issue about wifi. When the signal strength of wifi is not so strong (below -70 dbm), it tends to disconnect for around 10-20 sec and then reconnected again. This happened to me like 10 times since I got the phone. And wifi works perfectly without disconnections when the signal strength is strong enough.
Does anyone experience this issue? Or I got a defected device?
Thank you

Same here, sometimes it just disconnects ...

It is a normal stock android behavior, because android detects that signal of wi-fi is to low, and tries to switch automatically to GSM mobile data, or to another wi-fi if it is available in the area.

I don't have this happen but wifi signal is strong and also; gsm data is turned off.
That *may* help to turn that off possibly, as it obviously can't (now) switch to it?

Even if mobile network is off? Is there a way to change such behavior? I tried to find in the setting but what I just found is Aggressive WiFi to mobile handover, which was already turned off.

I think that it is called smart wifi, or wifi+ option in other types of android OS, and here it is just a automatic option in stock android i guess.
I don't mind it, because it will change my wifi router AP if it get stuck, and need an reboot, so it will automatically switch to another closest one that works.
You better think of some way to get a better signal then to turn off this function.
Try with aps like this on the link.

The thing is that wifi also disconnected when there's no other nearby networks to switch to. I did something to get better signal in my room but this still happened sometimes.

Question Data connection is active even when on WiFi

Hi all,
I'm noticing that the data connection seems to be active even when on WiFi. Is there any option that I need to disable so that the phone runs entirely on WiFi. I looked in the developer options and keep data alive option is unchecked. Am I missing something?

Hi, just go into Wi-Fi Settings / Advanced and switch off tab (Switch to mobile data)
That's all.

Hi. Thanks for this but this option was never enabled in the first place. Anyways, it's self corrected now...aah..the wonders of the tech world

It's enabled by default just to keep your internet connection stable when wi-fi has an issues.

It will re-appear occasionally. Even if you turn off the "Switch to Mobile Data" setting, the mobile data icons and wifi icons will appear concurrently on the status bar. This happens even when the wifi connection is solid. Usually the mobile data icon disappears after a few seconds or minutes on its own. I'm not sure if its by design (for MMS or RCS or something else) or if it's a bug. But you're not the only one seeing this. My colleague has an S21U too and he shared a similar experience.

I'm suffering from the opposite problem!
I *WANT* to keep mobile data enabled while connected to Wi-Fi, but the setting on my phone has no effect! When I turn on the setting, my phone will still ignore mobile data.
I verify this by connecting to my dashcam via Wi-Fi. The dashcam does not provide any internet via Wi-Fi, but merely allows my phone to view the dashcam output and stored files. But once I connect my phone to the dashcam, then my phone has no connection to the internet. I can't force it to use the mobile data at that point. The phone is not behaving as it should. My older phone, LG G6, is able to successfully connect to the dashcam and still access the data through the cell signal.
The S21 Ultra simply cannot achieve this. I have the T-mobile variant, in the US.
I believe this is a bug. Can you get this setting to actually work? Like maybe test it by connecting your phone to your Wi-Fi router but disconnect the modem from the Wi-Fi router?
I'll post a separate thread for this, because I think it's a bug and maybe others are suffering from it without realizing.

Question Wifi calls

Can anyone tell me if the radio has to be on in order to make wifi calls. When I'm in airplane mode and connected to a wireless network I get a message to turn airplane mode off. I have really bad cell service where I am and making calls is hit and miss.

I keep my radio off all the time (unless I leave my house) wifi on, airplane mode off and make and receive calls just fine.

If you have airplane mode off how are you turning the radio off? That's what I'm using to turn it on or off.

Mobile data always active in developer options set to off and I toggle mobile data off in Internet options. Unless I'm misunderstanding that should accomplish what your trying to do. For me this gives me wifi calling and receiving while I'm home (cause like you I have terrible reception) but when I leave my home and can pick up a signal I will still get calls etc

I must be missing something. I've turned off mobile data always active off in developer options and mobile data off in internet options. Right now I have no cell service, because it's so crappy here, am connected to my network but I still can't make calls. When I try I get a "mobile network is not available" error.

Check out under Network & internet, then internet. Your mobile network should be listed on top. ( I use google fi and it is listed) click the setting and make sure wifi calls is turned on. If it isn't there for you I would look around or check with your provider and make sure they allow wifi calling?
Or maybe someone else that uses the same provider as you can chime in here.

Thanks for helping me on this. Wifi calling is turned on. My carrier is Verizon. Could you look on your phone and tell me what it says below wifi calling, the smaller text, under Network & Internet, internet. Mine says "Call over mobile network" when wifi calling is enabled and "Off" when it's disabled. The call over mobile network seems to imply to be that wifi calling isn't active.

Yeah seems so. Mine says mobile data won't auto connect.
I'm unsure if it will help you however can't hurt to check or try. Under my provider (google fi) I click on the gear and my settings are mobile data, roaming, w+ connections and allow 2g are toggled off. My preferred network type is fixed on LTE and off course wi-fi calling under calling.
I checked under verizon and it should allow the wifi calling however it isn't very clear if it only allows it as a fall back option.
