T-mobile needs to fix the data issue with Canada

Being up there that long, you have more than likely exceeded your high speed data allowance while roaming and are being throttled down to speeds so slow, that they aren't useable for much outside of basic e-mail.  The roaming oartner for Canada, which is Telus/Bell, have some not great band deployments in that province.  It's mostly band 66/n66.  Have you tried setting your network selection to manual and selecting Bell?  Bell has some other bands deployed sparsely in certain areas but the speeds, if you aren't being throttled should be a lot better.  

I have been in Vancouver since Sept 29, 2024. About 2 1/2 weeks now. I've had the most horrible Internet service outside of the house. Text and messages go through. Apple to Apple attachments go through but Apple to android messages with attachments do not

I have a I have an iPhone 14 totally updated. The maps app works, but very slow to load. 
any other website takes too long or just times out. This is really horrible service. We used to have  MetroPCS last year and that's a subsidiary of T-Mobile or they purchase lines from T-Mobile and their Internet roaming was far superior than the service we have with T-Mobile right now in Canada. very disappointed.

I am in Canada right now too.  Everything is working fine here in Toronto and has been while I was in Cobourg, Oshawa, and Peterborough over the weekend.  

For those using Asian market devices, like Redmi.  Those devices might not be permitted on Bell or Telus due to their aggressive policies in not allowing what they deem as grey market devices to operate properly on their networks, restricting them to 3G.  My s23 Ultra has been solid every time I have come up here to Canada.

It is genuinely weird to comment that you don't have a problem every time someone else does. 

I come back and forth to Canada a lot.  A big chunk of my family is here.  If there were issues.  I should be experiencing them.  My device is a T-Mobile USA purchased device.  I also maintain a Canadian number and SIM with Rogers Canada in the same s23Uktra as an eSIM. 

Anyone having issues needs to be a little more informative on where they are experiencing them.  What device and model you are using.  Do you have data doing enabled on your device?  Is your line permitted to roam internationally?  If you go over your high speed data allowance, the data speeds will be reduced to basically unusable speeds, which some might interpret as their data not working.  

I am a very tech savvy person but those things mentioned above are all pretty straight forward.  I also know about the Bell/Telus grey market device policy because I was a Telus customer when they went to that b/s and deprovisioned my OnePlus 8T+ 5G from working on anything other than 3G.  After being told why by a senior network engineer for the company  I took that line back to Rogers.

That might depend on the plan you're on.  Older plans like Simple Choice where capped to ~256kbps.

I’m not sure about prepaid, but it may have similar issues.

iPhones are pretty much generic - especially for North America.

I haven't had issues - except when I first used T-Mobile - and that was because I didn't enable data roaming - back in 2015.  I've typically hit ~200-300Mbps on LTE in Canada, so no … Canada doesn't have a performance issue.  Typically you should be on Bell/Telus in most places.  Rogers isn't (or wasn't ) the easiest to connect to.

I've been having problems with this issue myself. I have a factory unlocked Samsung A716U1. My phone works flawlessly when in the US, but as soon as I cross the border into Canada, I get no signal and cannot call out or text. However, if I'm connected to a wifi network, I turn on Wifi Calling and my phone works as intended. I don't understand it and it's frustrating.

That sounds like you don't have roaming turned on in your devices Settings.  Roaming must be enabled if you want to have service when leaving the US.

I have data roaming turned on though. Is there another setting I need to make sure is turned on as well? 

Contact Customer Care at 611 or reach out to T-Mobile by sending them a DM on Facebook or Twitter to make sure international roaming is enabled on your line. 

Depending on the device you are using.  Canada's roaming partner, Bell/Telus, have a pretty basic network that primarily uses b/n66.  S20 FE's specifically have an issue with Telus due to some poorly deployed technology.  Have you tried manually selecting Bell when roaming in Canada?  That option offers some towers with b/n 7 and 29 connectivity in limited areas.  British Columbia is mostly b/n66 where Ontario has all 3 in cities like Toronto.
