T-mobile needs to fix the data issue with Canada

I was having this same issue and was able to resolve it by turning on LTE. On iOS this was in Settings > Cellular > Cellular data options > Voice & data > select LTE. Hope this helps someone. 

Canadian carriers have the same bands/frequencies that the US does - for the most part.

I had +200Mbps in NB/NS and ~75Mbps in PEI.  Similarly, in NE Ontario, +200Mbps on Bell and ~120Mbps on Rogers.

What T-Mobile plan are you on ?

I know that since I’m on an old plan, I get 5GB of high speed … and used it in a week while up there.

People spending money for iPhones/Androids/Phone plans don't need to be checking about all kinds of compatibility. We're not phone/data specialists.

Roaming was on. Full bars. It works everywhere I've ever been on the planet - except Vancouver area. I'm sorry but the data speeds can't be that typically slow in Canada. You can't even load an app to pay by phone to park on the street. We had to connect to Wi-Fi every time we wanted to park at a meter. Nobody's phone we were with worked.

I spent 1 week in NB, NS and PEI this summer,  and had no issues.  I hVe heard of some data issues with iphones when flying and picking up data afterwards 

I drive across from Maine, and most urban areas fave over 200Mbps.  in the past, I've used service in Quebec,  Eastern Ontario (Ottawa), Southern Ontario (Cobourg through Ft. Erie), and Northern Ontario,  and no issues.  Almost always it was Bell/Telus.   Very hard to roam on Rogers.

Also currently in Vancouver. Visiting from Los Angeles. Latest model iphone. Fully updated. Roaming on. My plan allows. I have perfect service in Europe. I have full bars and LTE at the moment and it took me 10 minutes to load this page and type this msg. It is atrocious. There is an issue that someone needs to figure out. For what it's worth it's not just T Mobile. My girlfriend who is with me is with AT&T and is having the same issue. Everything is so slow and sluggish. 

That sounds typical of Canadian carrier data speeds.  It will vary by region but still.  Data speeds in Canada don't come close to the what US carriers and other carriers around the world offer and deliver.

Do you have roaming enabled?  Does your plan allow you to roam internationally?  Is your device compatible with the bands Bell/Telus use for voice and data?  Bell/Telus are also moving towards devices needing to support VoLTE to have calling on their network at some point in 2023.

You may end up with what runs like a 2G connection on an old(er) T-Mobile essentials plan.

I am in Toronto right now roaming on to Bell 4G.  No issues at all.  Are ypur APN settings correct?  Have you tried manually connecting to the Bell/Telus network under Network Settings?  What device are you using?
