connectivity

Hi there,

So if you check out the link below it mentions steps on how to prevent charges when you're close to the border. Specifically, manually changing your network selection setting to koodo from automatic should help. 

Besides that, another option is to change your plan to a CANUS plan through self serve if this is a common occurrence. That way you wont be charged when using a US network anymore.

Once you receive the next bill, if there are roaming charges, feel free to post here again and a rep can verify if the charges are valid or not and can look at changing the bill. But it does have to be issued first before they can do anything about it. I hope this helps 🙂👍

I've tried to just choose a network, but when I did, koodo wasn't available.  I need to not have my network unavailable as my mother  and my husband have  life threatening health conditions and i need my phone to work. So if it connects to koodo then suddenly koodo is unavailable,  my sister or my husband can not contact me

Where are you located? Maybe Koodo’s reception in that area isn’t the best. You can check using one of these selected tools : 

Here's the list of the sites/app I have found while browsing Reddit and my thoughts about them. ( In no particular order)

Speedtest/RootMetrics- They seem to have two maps, one with 5G deployments and one on their mobile apps. Both are kinda useless. The 5G one seems to just have general info on where 5G exists and the tower locations are off. The mobile apps seem to be better but the map view has too little data and the two categories "Best" and "Most Common" seem to be lacking. I hope the RootMetrics acquisition helps with that, although I think speedtest has more data points than anyone period, but they seem to only show it in simplified form. The site RootMetrics has for individual cities/metro areas is way better, but is only limited to certain areas.

CellMapper - A very good website for pure data and accuracy. Very detailed and helpful. But it's a little cumbersome to collect data and the app/site needs some work in order to be more user-friendly. I personally would love it if there was a simpler site toggle/feature where instead of clicking on a tower and then seeing the sectors. It kinda copies the T-Mobile mvno sites where you tap a location on the map and it tells you what bands are available in that area. That idea probably isn't perfect(or possible, I have no clue how this website is run on the backend), but I think it would increase usability. Also, I know an iOS app is never coming but that would be nice. Also, some site enhancements like setting the default region on the desktop site would be nice, instead of sending me to the middle of the ocean every time I load the site would be nice. Overall great website. Much thanks to the people who run it.

Open signal - The app is very user-friendly and the map seems to be actually useful as compared to the speedtest app. But afaik it just does not have enough users, but I might be wrong. Just wish it was on the web. Also, mapping capabilities seem to be lacking.

nperf - The site is very simple and user-friendly. But is lacking in the amount of data it has. I do like the toggle for download bitrate though. The apps are okay. Seems like no one really uses nperf. It does have a good mapping interface though, and it gives stats on how much of your mapping session was 2G,3G,4G, or 5G.

FCC - From what I gather seems to be fairly accurate to a certain extent but, is a year old.

Whistleout - From what I gather complete crap and not useful.

I'm in southern Ontario and this only seems to happen when I'm in my apartment.  I only live 2 or 3 blocks from the Detroit river, so may that's it. 

It still shouldn’t be an issue but unfortunately there can be small areas where some networks have been reception. You should enable wifi calling so you can still have signal in your home when the cell network is not good.

Apartments sometimes interfere with the cellphone reception as concrete blocks some of the bands especially in th 5G spectrum. If you have good coverage outside your apartment block but not inside, this could be the reason why. 

Yes. That's what I thought.  

To summarize, enabling wifi calling would be your answer (assuming you have reliable home wifi.

Give this a try and see if this is to your satisfaction.

If not, then I would echo Oliver’s suggestion of signing up to a Canada-US plan.  Then it wont matter if you connect to a US network across the river.
