Is there an app that switches an Android phone between regular mode and dumb 2G mode? I.e. which makes the phone only communicate by 2G phonecalls and SMS, until you re-enable a proper data connection?
I'm using /e/ now but would like the option of becoming a 'dumb' mobile user again temporarily!

Can anyone tell me how to do the simultaneous voice and data? I remember my Hermer used to let me do that. Any solution?
Don't know - it just does! However only a 3G network will support this, so make sure that you have the H or 3G symbol at the top. If you are on 2G, the data connection will terminate whilst on a call.
I think that some phones had two radios..one for voice and one for data..I'm guessing the TP doesn't have this
is there some way how to set the HTC PRO to the situation that the phone has priority from the EDGE?? something like that, when i am in data connection and there was call comming, that the data connection will close and i can take the call??
Now i am unreachable when data conncection
A 2G network is NOT capable of both telephony and data at the same time - it has nothing to do with the phone. As to what takes priority - i am not sure, but if you have an active data connection, i guess the network sees this as the phone being "engaged". THis is a limitation of the network and not the phone. I use my phone in 2G mode with the data connection always open - to allow email push. When i get a phonecall, the data is dropped by the network to enable the call. You need to ask your network provider.
3G can carry both data and telephony at the same time and doesnt need 2 radios. The touch pro supports this.
Ok I've got a few questions about the different network types and battery usage.
As far as I know there are 4 different possible scenarios:
3G mode active
3G mode active and connected to mobile data (3G/H showing in notification bar)
2G mode active
2G mode active and connected to mobile data (E or G showing in notification bar)
Currently I have settings default with "Use only 2G networks" unchecked, and "data enabled" unchecked. I have tasker made to automatically turn mobile data on whenever I open any app that may require it, and then turn it off after the app closes, or I can switch it on from the status bar power control.
This is because I assumed having it constantly activated would consume more power. Is this true? does it consume more power having data enabled even when no traffic is going through? If this wasn't the case, I might as well leave it enabled. However with my current system I could still be saving power because if I leave data on, traffic WOULD periodically be used for automatic sync and apps randomly using network and stuff.
The other thing I was wondering about is if there was any major difference in power consumption between 2G and 3G network modes with no mobile data connected. if 2G uses much less power, I could have it set on 2G by default then use tasker to switch to 3G and activate mobile data when opening any internet requiring app. Are there any other advantages of having 3G active over 2G other than mobile data transfer speeds?
Thanks for any help!
Imho your settings are good. Mobile network is one of the battery killlers, so not using (or better using it when you really it), is very good. You are right, 3g has a higher speed on mobile network. Whereas the 2g-network has a much better network coverage. And the permament switch between 2g and 3g drains the battery very fast, too (happens e.g. when you travel).
To sum it up: Use 2g and mobile network off. If you need to use mobile network, turn 3g and mobile network on. Are you done, turn them off again and switch back to 2g.
When you say mobile network, do you mean when an active data connection is enabled?
Because just by the name 'Mobile network", you can be connected to a mobile network for calling and texting etc. without being connected to mobile internet/data.
Is there a difference in call quality between 3G and 2G networks?
Also when toggling between forced 2G only and 3G there seems to be an inactivity period where the reception icon at the top shows like 'disconnected' like it cuts all network communications, then shortly connects again to the specified network type. This delay might be annoying when trying to get internet fast on apps that need it... might not be worth the power saving, if it is only minimal power saving

for the best battery duration, use GSM ONLY!
Does the idol automatically use wifi when it's available for data? I just got a sim card and activated using BYO Wireless (T-Mobile).
My old Tracfone phone had an option where you could turn off cell data and use wifi only.
Yes and no..the priority is wifi but the cell radio is still used to receive sms's and other cell phone specific notifications...when you make a call while on wifi it's still using the cell radio not wifi for the call. You however have to have wifi on and the hotspot "saved"...if you want the phone to automatically grab any available hotspot when in an area look for an app like "wefi".
Some people make things so complicated.
The simple and best answer is yes, Wifi always takes priority over mobile data if the phone is connected to a wifi signal. This is standard on all phones as far as I know.
I realize it uses cell signal for messages and calls but will it use WiFi for surfing the web and email?
Thanks shodan. I posted before your reply..
Hi Guys,
I am here with a..I hope possible to solve situation.
I have switched to our local carrier, which provides only 2G and 4G connection, but... I have 1GB of data for 4G, but my OPO is sometimes switching to EDGE, which makes me fury, because I am paying for anything transferred through 2G (separately as it is not in the data package I have), but all calls are on 2G, which makes restricting the connection to "LTE-only" impossible, becuase it would result in no access to the calls/text messages.
I have found this article
http://editorsean.com/articles/how-to-force-three-to-use-3g-and-4g-only/
which is really great, but with those options I am forced to use GSM/LTE and such..
Is there any chance of letting my calls and text messages just using 2G network as usuall, but forcing my internet access using just LTE ? There is of course an option for disabling "national roaming" (I hope, it is called the same in english), I have it disabled, but it is still connecting to the 2G and draining data from it...
Is there a chance it is a problem from my side ? I did not factory reseted the phone since buying, doing just OTA upgrades and such, so I was thinking, if the system is not kind of bloated...I had some weird things happening with it too in the past - recently I have seen that in the battery saving mode I could see some like various screen brightness jumps while playing a game for example.
Greetings all
is there a way to make android (using non-rooted Samsung S20) automatically switch between 2 data Cellular data SIMs based on what application is used. for example when running App X it uses SIM1 (private network LTE) and when running other apps/services the phone would automatically switch to SIM2 (normal internet LTE) .
basically I am trying to run all applications seamlessly without manually switching between the two data SIMs. currently android applications don't work when using SIM1 and app X doesn't work when using SIM2 .
if for whatever reason the above is not achievable on non-rooted phone, as a last resort, is there a way to get the auto-switching to work with WIFI(full internet access on all applications) and SIM1 (private network LTE). if this works i have to use an external 4g hotspot router.
I tried using the android application firewall(in the settings) to only allow App X to use LTE and other apps to only use wifi. unfortunedly that did not work as the auto switching to LTE does not happen even after enabling "wifi assist/wifi+) from the wifi advanced settings.
A third option: is it possible to connect to wifi and SIM1 at the same time?
