[Q] Going to Canada, want to use wireless by not cellphone

I've got a stock S3 with T-mobile service and planning a trip to Canada. I don't want any roaming or connection charges while in Canada, I'll just do without the cellphone, but I still want to be able to use the S3 to connect to wireless at the hotel for Skyping, email, etc. What kind of settings will I have to change on my phone, if any, to ensure I don't get hit with any roaming or data charges while using my phone?
Thanks.

I think you can find and uncheck "data roaming" and "use packet data" in settings>>More settings>>Mobile Networks
Alternatively, you could turn on airplane mode and then just manually turn on wifi. All other radios should stay off.

Thanks. With the "support.bell.ca" method - I just don't know how cell phone connectivity would work; would I still be connected to the cell phone towers and receive phone calls (which I don't want) under roaming?
I like the second solution. I knew Airplane mode would turn everything off, but I didn't realize I could then turn wireless back on. I thought it was a all or nothing setting. Learned something useful.

I edited my post thinking that same thing. I believe disabling "use packet data" does disable your connection to the network and therefore, no calls. I think using airplane mode is the more certain option though.

I agree. And I don't have a "use packet data" option under Mobile Networks, so it doesn't matter.

Just turn on airplane mode. Then manual wifi. The turn on wifi calling and check prefer that only instead of cell calls. Boom.

Interesting if that would work. But if you attempt to make a phone call, it says Airplane Mode is activated, turn off Airplane Mode to make a call.
Which brings up the question, can I use wifi calling while in Canada if I have wifi service?

I'll pay you to fix this. *PLEASE*

Basic info:
- I'm on The People's Rom GS3.17
- I'm using KTweaker and running one of their profiles
- I'm ATTEMPTING to use Tasker to regulate Wifi home/out and data home/outside
So pretty much here's my problem:
I've attempted to use Taster to make sure Wifi is ON when im at home and OFF when i leave home (according to cell towers)
I've also tried to make sure Data/Wifi is OFF when screen is OFF and ON when screen is on.
But even if Tasker was working perfectly, this problem still persists and this is it:
1) When I use WiFi at home, every so often, it will just shut off (even if the screen is on) and it will revert to 3G
2) The only solution to this is to turn off Wifi, then turn it back on, and only THEN will it capture the SSID and connect to the internet.
Example shown below:

"lightbox_close": "Close",

}
In the above picture, "InternetOnly" is the SSID for my university and yet, with Wifi enabled, it doesn't access the damn SSID and the internet! It is using 3G. In fact, when I click to connect to that SSID, it says "out of range" which is BS. Only when I reset the Wifi connection does it connect me to the internet/ssid. Exact same problem occurs with the SSID at home. Wifi policy is set to sleep "never" btw.
As for Tasker, this is what I'm using for automation which is failing epicly (I deleted the task about cell towers because it was getting annoying):
I THINK the problem would work if I stock resetted my phone using ODIN but I don't want to
Someone please help.

Okay so it happened again; I'm at home, and it was connected to WiFi, and now it's back to 3G even though WiFi is enabled. When I click to connect, it says "failed to connect to network" even though I'm literally a few feet from the router.

In TPR you have to freeze in Titbu just like you did good move. The settings have it removed because so many people where messing things up not knowing what they where doing.

Well so far I just flashed the .zip file and removed it altogether...let's see how it goes.

Any update on this? Just curious.

Yeah the update is that even after flashing the damn .zip, the WiFi still randomly disconnects from my SSID (even though the WiFi itself is enabled)
SUPER ANNOYING!!!

Should I just change the SSID? I heard sometimes it doesn't like upper-case letters and numbers.

[Q] Tmobile Note 3 on ATT network?

Anyone else running a Tmobile Note 3 on the AT&T network? Is there any difference in reception or LTE? I've seen in other threads people complain that they dropped calls and had less reception with the Tmobile hardware on ATT, I'd be curious to see DB measurements and not simply rely on the reception bars. Also heard complaints that the Tmobile N3 doesn't hand onto ATT LTE signals well.
Also using the Tmobile Note 3 on the ATT network does;
1) does tethering still work?
2) does it work with an AT&T microcell?

My wife and I both use straight talk which runs off of AT&T towers and when I'm at the house I have full bars and my speed was 20 if I remember correctly, at work I get 3-4 bars but never any reception problems. Hope this helps a Lil bit.

I'm running my N900T on AT&T with CM 11 and have noticed that my phone randomly drops back to Edge and even G sometimes. It has completely lost data access occasionally too. I put my phone in airplane mode and it goes back to full LTE, but that's bothering me. I don't know how to fix it.

You can download Advanced Signal Status. Then go to additional info then device info and you can change the network mode to LTE only to force it to reconnect to LTE always.

I tested the app here, and although it says my LTE signal is at 100%, my data connection is being disabled every time I make a call. I tried changing the preferred network type to LTE only in the phone info menu and calls drop as soon as I hit the call button on the dialer. Also, in the phone info menu, the option to enable/disable data shows only as "enable" during a call, which means data is disabled, and clicking it does nothing. As soon as I hang up, my data connection restarts and goes to 2G. I don't know if this is a problem with CM 11, so I'll try a Touchwiz ROM in a minute. Any other suggestions?

No problems at all with touchwiz. Probably a CM11 problem.

[Q] How to disable 2G radio (voice)?

Anyone know how I can disable the 2G radio? I am using an LTE/3G data-only sim with IP calling, so have no need for 2G. In battery stats I get a solid red line for mobile networks, as the phone is always searching for a voice network unless I put it in airplane mode (no good because I need mobile 3G/4G data). I would like to restrict the radio to only 3G/LTE if possible. I have root and xposed.

You should be able to do it from the service menu. Sorry I don't know the dialer code but I'm sure I've seen it mentioned in one of these threads (I access it through 3c toolbox.)

I found the services menu, but that just sets preferred data network, same as you can do under mobile networks in regular settings. It doesn't result in disabling the 2G voice (as if the phone were an LTE capable tablet).

Have you tried the lte only setting?

Yeah, it restricts my data connection to 4G, but still get red bar for mobile network in battery stats and mobile standby stats report 100% no connection, so seems like it still searches for voice service.

You could try posting a request for someone to build an xposed module in this thread. You never know it might spark someone's interest.

Hello, I posted in Project T Kernel thread about battery drain and network signal search. The problem is that the phone is continuously using the cell network even when in airplane mode and no sim is present in both trays. I also get the same solid red line of continuous activity use of cellullar antenna. What does your battery stats details look with airplane mode on?

With airplane on it shows no mobile connection, as it should.

Solved
After some net trawling, found a thread on an English language Japan tech forum about the problems of using data-only MNVO sims on Android phones. It linked to some Japanese tech blog site with a datasimpatcher exposed module. Installed the module and BINGO! Now getting green for mobile connection in battery stats. Hopefully this will have a positive effect on my battery life.
Link to patch, in case anyone else uses a data-only sim:
http://www.akaitori.info/datasim_patcher.apk?attredirects=0

Interesting, it should use less battery since mobile net signal bar is empty. Mine is full even without sim and in airplane mode, red bar means searching for signal and that modem power is on. How did you make the fix work? I don't see an option for zenfone 2, only samsung, htc, etc I installed but cellular network still full red line.
How you completely turn off cellular modem?

Turning on airplane mode should turn off your cellular radio completely. Strange that it doesn't. Regarding the patch, I simply installed it, turned on the module in xposed installer and rebooted. I left it in patch mode 0, which seems to work.

I still get a red line in battery stats. How did you manage to get rid of that?
@corrsea I bought 3c toolbox but I can't find the service menu option. Any idea?

Open battery manager in 3c. The middle button at the bottom of the screen is called tests. It opens the menu.

I deleted dialer&related stuff so it will fc -.- I only use VoiP. Do you get empty bars in cell network of battery details section?
Look at my earlier pic, modem always searching for signal (red=low signal or searching) even with no sim and airplane mode on. Some device's modem can be physically removed.
I found a flashable zip and script that will completely power off the cellular radio but it shows pie security check error in terminal -.-

Disabling VoLTE (Verizon)

Hello all!
Is there a way to turn off VoLTE? I use my phone as a hotspot, so when I get a call, I don't have internet access. I'm assuming this is because of VoLTE since my last phone (Droid 4) didn't have this issue.
Thanks!

I always thought having that option disabled is what caused data to turn off during phone calls. I have it enabled and I can still use data while on the phone. That's the toggle to the off VoLTE though.

Sounds like you aren't using VoLTE in the first place. Turning it off won't give you data during a call it would do the opposite.

Talk and web is only available if you have advanced calling option turned on within your verizon account. Its free.

It doesn't sound like you're using VoLTE exactly because you stated you can't use simultaneous voice and data. Here's the deal: To save battery power or whatever, the additional radio added to Verizon and Sprint (CDMA) phones to enable 4G has been removed from a lot of them, rather converged.
Verizon has always had this problem and they got around it by, finally, adding an additional radio to handle the 4G to many phones. On CDMA networks it's either (I think analog) voice or (I think digital) data. Then, I guess expecting this great big transition to VoLTE (and only needing one radio to simultaneously handle LTE and Voice over LTE) "they" reverted phones to the original model. I mean that has to be it... I would gladly charge my phone more to be able to be able to hotspot and talk! Or maybe they want to sell more JetPacks and separate line access fees!
(This is what allows for all that red on their coverage maps as Verizon's original voice frequencies do rock for signal strength and reliability. The data maps look a lot more similar amongst the carrriers: concentrated on major "markets" as the efficiencies of cities drive the capital to create the networks--rural areas have lousy 4G coverage).
The GSM networks from T-mobile and AT&T automatically fall back to 2, 2.5, 3 and 4G frequencies and can use the newer and the older networks at the same time. You also get better conference calling (up to 5 people) and call management on the GSM based networks.
If you want to use voice and data at the same time on Verizon, edit your account preferences to enable Advanced Calling 1.0 for your line. It is free. Also enable Enhanced 4G LTE mode as shown in the screenshot.
But VoLTE seems to bring its own issues: call complete rates will drop, call quality will drop, static bursts occur at the beginning of calls... it's a real mess.
I really miss T-Mobile, but their network isn't as good and I save money being on the family plan with others on Verizon.

Hi guys, I am having the opposite issue.
I can't get VoLTE ("HD Voice") to work. As a result, no internet when I'm on a phone call. A real pain in the butt.
I'm on CM13 on my Nexus 5x and using Verizon.
I had previously activated this feature on the Verizon website, and it shows the VoLTE flag is 'on' in the phone info/service settings menu. I've seen posts elsewhere where people say CM13 is not working properly with VoLTE.
Should I flash to a different ROM perhaps? Appreciate any ideas...
