[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",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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.

Sounds like the connection Optimizer is kicking in. Have you disable/unchecked it? It's in Settings>More Settings>Mobile Networks>Connection Optimizer
You can check out this thread here

It's not there for The People's Rom. IDK how to access it.

Did you try his zip?
Make sure of course that you back you system up first!

I just used Titanium to freeze it. Hopefully this will work. I haven't used the zip to remove it though, I'll wait this out a few more hours.

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.

Wifi and data problem

I have a T-Mobile htc 10 and recently updated the phone that was sent by T-Mobile (1.81.531.4). Lately, when I'm connected to wifi and leave the range of the wifi the phone will not connect to the data network. It will show 4g (big icon) with 3/4 bars but there is no connection. I can't send text messages and the internet says I have no connection and the web page won't load.
Turning mobile data on and off won't do anything. I have to turn on airplane mode and then turn it on. That's when the mobile data starts working.

I am having that issue as well. I rolled back and the problem went away. Must be something in that update.

How did you roll back? Are you rooted?

Make sure "Auto switch to mobile network" is checked under your advanced WiFi settings.

I'm also seeing the same thing. Has this issue been resolved? I've just applied "Auto switch to the mobile network" so only time will tell.
UPDATE: applied "Auto switch to the mobile network" unfortunately that did not fix the issue.
My carrier is T-Mobile
Build: 1.81.531.4

I have an unlocked HTC10 and use it on Tmobile, I had that exact problem with mine also after an update which i dont remember the number, but after the last update from last month (1.91.617.1) it got fixed, i was able to make it work with a trade of a little battery life.
My fix:
Go to developers options and enable the "Cellular data always active" that way even when you are connected to wifi the phone will leave the 4g/Lte connection open.
Try that at least until they release the OTA for your phone
Let me know if that works.. good luck!

kelbaez: Thank you I'll try enabling the "Cellular data always active". I'll post back if it works or not. (9/23/2016)
UPDATE: 9/25/2016 Since I applied kelbaez fix on 9/23/2016 phone has not had an issue. Until today.
While traveling (phone was never connected to a wifi) phone seem to have lose connection with T Mobile's data. Enabled and disabled airplane mode fixed it.
However, I still feel kelbaez has fix the issue of being at home and connected to wifi and with his fix I have not as of yet lost data connection. FYI, prior to his fixs at less once or twice a day.

Glad I stumbled upon this thread..been having the same issues. Hope it gets fixed in an update.

WiFi connection while data is on

Apparently Pixel phones does not route connections correctly. I have an issue with a wifi device in my car. My car connects to phone through wifi for music and other services but since this wifi has no internet, my phone automatically keeps data on. When this happens, the car app does not detect the connection because apparently the Pixel phone routes all data through only the "Active connection" which is cellular in this case, if i turn off data, then the app works. This is a petty as its' working fine with other phones like Samsung or iPhone.
Also the car actually needs the data connection on my phone for navigation, update, etc... and with this scenario, it does not work.
I made a test at home with a router. I connected the phone to router which has no internet connection, i then opened chrome and put the gateway address and it did not open the router page. I then disabled data and it was able to open the router page. Again, this is only with the pixel; other phones work even if i don't disable data.
I have seen similar issues with also other WiFi devices. See below link
https://forum.dji.com/thread-103340-1-1.html#post_858055
Any thoughts or nothing can be done with this pixel phone.

Under settings- network and internet- wi-fi- wifi preferences- advanced there is a setting called switch to mobile automatically. Turn this off, it turns mobile data on when there is no wifi but you are connected to WiFi. Give it a try and report back.

thats very strange. i have also latest build. just updated today with February security update?

Yep, I have the February update just got it yesterday. this options been on there for quite some time for me I don't know if it's a Verizon thing but I remembered seeing it for some time.

so looks like i am stuck with the wrong phone as there is no solution

One more option not sure it will be work but worth a try. In developer options (if you don't know how to enable it Google it) under networking there is a toggle for mobile data is always active. Mine is toggled on, see if yours is and change that option to see if it makes any difference. If it's off turning it on may bring in the other option in the settings menu, if it's already on, turning it off may do the same thing as the other option in the settings menu does for me.

cannot turn off Mobile Data

Hello,
I would like to check if I am the only one with this behavior:
I am on stock android 10 version February update.
I tried to turn off the mobile data, turn of the WIFI but Is see that some applications such as whatsapp, still connected to internet and are able to sent messages.
Quora is able to open treads and Chrome still able to browse web sites.
I tried try to disable 4G calls but no changes.
It is a problem for me because if I travel with my smartphone consuming data in other countrys it will be very expensive and plane mode if not a good solution as I need sometimes to tun of data but turn on the WIFI
I am android user since several years and never seen similar behavior before.
Thanks to share your experiences tuning off mobile data with Pixel 3 XL.

and I still able to browse on the internet

With data off what does it say when you enter *#*#4696#*#* and enter Phone Information? Could you give a screen shot? Make sure to blank out your IMEI info before posting. Or just what does it say under the "Roaming" and "Data Service" lines. Should say "not roaming" and "disconnected"
Also, under preferred network type what is selected. I wonder if you are getting 2g or something coming through. When connected with data turned off does it have the same speed as your LTE/4G?
