Hi,
Does anyone have an application to turning off the GSM Radio ? I mean it's only turning off the SIM Card ? I read one topic below, they explained about SIM Status Switcher. But I think that program is too complicated Because I just need a program that only turning off the GSM Radio, not more.
I need this because sometimes when u are on the plane, it's forbidden to turning on your gadget that have radio signal like Handphone, GPS, Wireless Lan etc.
Thanks a lot 8)
Have you tried flight mode? will this do what you require? tap on G icon or signal strength meter and option should pop up. 8)
Try radiooff
see
http://forum.xda-developers.com/viewtopic.php?t=36788&highlight=radiooff
The easiest (and most effective) is simply to tap on the signal meter at the top menu bar, then choose "Flight Mode".
It then displays an "x" on the signal meter, and when you tap on teh signal meter again it tells you "Radio Off" which should be handy to show any nagging flight attendants.
oh I'm so stupid :?
Just tap on the signal meter. Thanks guys.
Hey all,
I'm using Cyanogen's newest (4.2.6) and I'm curious if there's a way to turn off the cell antenna kind of like airplane mode. The problem I have with airplane mode is no wifi. The reason I'm curious is because I work in a place with no reception and it kills the battery as well as causes problems with texting on the Roger's network once I'm back within range.
I know you can do this in the hero roms, I'm wondering if anyone knows of any apps or options somewhere that might do the same in a non-hero rom.
From your dialer call

Then Phone Info and then
"Turn off Radio"
Is there any way that you can turn off the 3g to save battery because on other android phones like the g1 it allows to turn off the 3g and seeing this is the first 4g phone EVEERRRRRR!!! i think it should have some way to turn off the 3g capability to save battery,,any suggestions
You are able to turn off 3G completely by going to Apps>Settings>Wireless Networks>Uncheck Mobile Network
yea but there gotta b a way without disabling the internet
No way because voice and data are 2 separate signals and cant be used simultaneously. The 3g is the thing that kills the battery because it is always looking for a better signal. If you turn that off, voice will stay at "1x", thus saving battery and you can still receive sms and mms
I have suffered from this problem for a while now. When I am on wifi at home or elsewhere and then go out of range and the phone should flip back to a 3g/4g signal all i get is an exclamation mark next to the signal bars. I then have to carry out a reboot to enable use of 3g
This happens about 80 percent of the time
Anyone else seen this?
I feel the same. I fix it with a tasker profile. When I lost wifi signal Airplane mode active for 5 seconds and then switches off. Since turning it on and off airplane mode reconnects the 3g.
Sorry for my english.

Hi
I have had my Z1 for 2 weeks and am experiencing the same problem. My usage of the phone requires that I switch between WiFi and either of the 2 SIM cards for data on a very regular basis. The Mobile data connection does not activate when coming off WiFi and I am forced to mess around switching the phone off and on etc in order to reactivate the Mobile data.
a) Is there a quick work-around to overcome this issue ... & ...
b) Will the OTA CM13 udate in March overcome this?
Thanks for your time in shining any light on this problem.
I'm playing with tasker trying to create profiles for things without much success. Could you please give me some help on setting up the profile for this?
Thankyou
I have the same problem. I usuallt swithc from 3g to 2g and then to 3g again, and the signal comes immediately
Every one got that problem . Y can try other flyme 4.5.4.3 (eng only) or zui . Modem works perfectly (except hotspot+4g)
My wife and I live up in the foothills of Colorado where there are no Sprint cell towers. There is one cell tower which our Sprint S7 edges can barely pick up that comes and goes and indicates that we are roaming. For a few seconds our phones might see it but then it will go away for minutes, then it will come back only to go away again ... etc. In any event, it was necessary to use Wifi calling when we are at my home. Prior to the Nougat upgrade everything was fine. As soon as we walked into the house our S7 edges would connect, Wifi calling would activate and would be functional. After the Nougat update we have discovered that Wifi calling no longer works unless we can also see that one roaming cell tower. Then Wifi calling turns on, stays on and we can make/receive calls. I emphasize that this behavior occurs with both our phones.
This problem makes all the Sprint stores basically useless. Since they are located where there are towers, Wifi calling works as expected. As a result Sprint has been absolutely no help. I am wondering if anybody else has had problems with Sprint Wifi calling when unable to see a cell tower? If so could you work around the problem? I am open to suggestions. I consider this a bug in the Spring S7 edge firmware.
BTW, I know that when I can make a call, Wifi calling is used because the pop-up "Congratulations you just made a Wifi call" appears. I purposedly have not turned that off to be sure I am not using that one roaming tower. What is interesting is that I only need to be able to see the "R" by the triangle showing cell tower strength (don't need any bars) and then the Wifi calling icon will turn on. At that point I can make a phone call and even if I lose the connection to that one cell tower (i.e. the "R" disappears) the Wifi call will remain active. I can go anywhere in my house and not drop the call. But once I hang up, the Wifi calling icon will gray out with a slash through it, the phone will indicate that there is no network and the phone can only make emergency calls.
If I cannot get a fix to this problem then I might just have to go back to the last Marshmallow firmware and block the update if possible.
just for the hell of it to check, I turned on airplane mode and left it for 5 mins, leaving it on turned wifi on, and wifi calling connected within a few seconds of wifi connecting. I am on the nougat update. I have absolutely no cell signal as that is turned off. I am able to make calls without a problem.
Reboot your phone into recovery and clear cache and try again.
also, you may want to check and make sure "smart switch" is turned off. it's under the connections > wifi > advanced > smart network switch. I haven't tested it, but in theory it might demand you be connected to a cellular network to work and be causing your problem.

Thanks for the suggestions. I tried several things. First I verified that I already had "smart switch" turned off. So I went ahead and turned it back on... no love with that feature either turned on or off. Second, I rebooted as you suggested into recovery and cleared the cache. That also did not fix the problem. Third I tried the same experiment as you and turned on airplane mode. I waited a bit (maybe not the same 5 minutes) and then turned on the Wifi and Wifi calling. Again no love. I even tried to make a call and the phone told me I had to turn off airplane mode. For whatever reason Wifi calling will only activate when the phone can see that one tower and starts roaming. At least I can use your experiment to demonstrate the problem at a Sprint store. I might just try using Odin to flash nougat and start clean and see if I cannot get this to work that way. I really don't want to go back to using the Airave although that was pretty reliable for me.

So question is, if you go somewhere with signal and wifi you can connect too, turn on airplane mode, leave it on and turn wifi on, does wifi calling work. If not then for sure a reset is in order.
If it does work, then that just tells me the phone isn't really turning everything off with airplane mode on (which is lame) and sprint just goofed up the nougat update and you are the extremely small % that falls victim.
I haven't been able to get WiFi calling to work on my Edge since new. UNTIL I upgraded to Nougat. Now it seems to be working fine. Go figure.

Okay some interesting data. I did exactly this experiment this morning. I drove into my office, connected up to the office WiFi and placed my phone into airplane mode. I then turned on WiFi and WiFi calling. Voila I could make a WiFi call!
However I did not stop there. One of the keys to all this is that the one tower happens to cause "roaming" if my phone was lucky enough to connect to it. So for grins I changed the network mode from automatic to LTE/CDMA (Sprint & Verizon are CDMA). When I was back at the house guess what... WiFi calling now works. Interestingly the phone is in "searching for service" mode which implies that the one cell tower seen from my house is either AT&T or T-Mobile which use GSM. By turning off automatic mode everything worked.
It is kind of a bummer but what seems to fix the issue is to choose Connections->Mobile networks->Network mode->LTE/CDMA. Each time a switch is made from Connections->Mobile networks->Network mode->Automatic back to Connections->Mobile networks->Network mode->LTE/CDMA, etc. the phone has to be rebooted. Unfortunately while traveling in a car Automatic mode is desired and at the house LTE/CDMA is best. Switching back and forth will be a PITA because of the reboot but at least I don't have to go back to the Airave.
I tried to explain this to the Sprint rep. on the phone this evening but he did not understand. Over the weekend I might try a clean install via Odin and see if that improves things. I hate doing that because it takes a fair amount of time to put the phone apps back together. I also have my doubts it will fix anything. IMO something broke with the Nougat upgrade and nothing I do will fix it. And as you point out, I am in that very tiny percentage of people who might actually experience an issue.

Just out of curiosity have you tried turning your roaming off? Or adjust the settings to not connect?

Thanks for the idea.
So while my wife and I were having lunch in town this afternoon, I took our phones and toggled LTE/CDMA and Automatic modes. When we arrived at the house with the phones in Automatic mode WiFi calling worked. I think as long as the phones do not roam and connect to that GSM cell tower, WiFi calling seems to work. So I put both our phones into Home only mode (Settings->Connections->Mobile networks->Data roaming->Roaming network->Home only). So far so good. Both our phones have had WiFi calling activated now for several hours so I think the strategy works. Turning roaming on and off is not as painful as changing the network mode. Still the Nougat behavior is very different, I dare say, broken from Marshmallow behavior.

It's weird and I would bet money something they accidentally broke and such odd and perfect conditions have to be met to make it present itself, they probably had no idea. The sad thing is, this bug probably affects so few people, and most will probably not be tech people and will just get frustrated and switch carriers, and so the bug probably won't ever get fixed, except by accident possibly.
On a side note have you tried changing your location settings to GPS only. If you have it set for a method that looks for towers that might be the issue right there. GPS-LOCATING METHOD-DEVICE ONLY.

I just tried the experiment. That did not work and in fact broke WiFi calling. So far the only solution is to toggle the LTE/CDMA and Automatic network modes where there is a Sprint tower preferably and then turn off roaming as I drive up to the house. Then WiFi calling works without issue. Nice thought though.

Okay so things get even worse. Today I drove up to the house with roaming turned off and network mode automatic. After parking the car and walking to the end of the driveway to retrieve my garabage can, not only did WiFi calling fail to activate but I could not turn roaming back on. The Settings->Connections->Mobile networks->Data roaming->Roaming network menu is greyed out. IMO, Sprint has hosed up their edition of Nougat. So I will be left with a brick as a phone while I am up here at 8400' at my house. I am quite pissed.
FWIW, what I think happened is I walked to the end of my driveway and lost my WiFi connection. That caused WiFi calling to shut off and now it will not turn back on. At least if I could get roaming turned back on I could try and connect up to that one lonely GSM tower to possibly fix this issue. But I cannot even do that because the Roaming network menu is greyed out. I am going to have to drive into town just to fix this problem. Ugh!

Found the fix... Updated the PRL & Profile. I guess the phone lost its mind and could not find it once the WiFi was dropped.
Many retail mobiles have "Wifi Calling" function but not any menu entry to enable , The APP can check the hidden function and enable it if can use.
