Data roaming even with data off

I was travelling to the US and, while in Canada just before taking off, I turned off the mobile data on my phone, just to be sure it won't try to connect as soon as I turned the phone on in the US. I'm positive the data was off because I was not able to use it unless it was connected to the Wi-Fi. Just found out that Koodo charged me $5 for mobile data with a few 4-5 MB each day. How is that possible that even when the data was off, the phone connected and consumed data?  Any ideas?

@Jonny:
How did you turn off the data? Did you turn off through the "mobile data" switch or did you go into each apps and turn off? which phone was it? I saw some people making complaint about leaking data of few data amount like 0.01MB. 4,5MB each day could be from something else.

I have an android OnePlus 6, I turned the data off on Settings > SIM & Network > Mobile Data switch

I would double check if you turn off the data for the correct SIM slot. Have you check the mobile data usage, and see if there was any app showing up?

Yes, only one active SIM, for sure was the correct one. The data was one very small bits during each day. I was in a conference using the phone on wi-fi all day, if I was on data my bill would be huge by now

@Jonny: you could try to send message to Koodo facebook (https://www.facebook.com/Koodo) and see what they could do. $5 was a small amount, but you might want to know the exact cause so you could avoid it (or avoid the calling) next time.

There are some people that have had a problem with data leakage even with data turned off while roaming. If you are positive you had data turned off and minimal data(4-5MB seems high for leakage) was used while roaming, you would have to contact Koodo to dispute the charge.

On my PC Mobile this was happening monthly to me and I was getting charged for data leakage, when data was off except to send a text with a pic while on wifi. I was charged $11 for like a half a MB since they charged $11 for 500MB on my monthly plan. They kept giving me my money back, but every month I had to explain it, and then I started having to explain why I have $11 credit the previous month, but I also needed this month. I decided to switch. I travel to the USA a lot, so I hope this data leakage problem does not continue when I am there.

If this was happening even though your data was disabled and you never restarted your phone, it could be an issue with your device

I don't think it was my phone, but I have since bought a new phone and switched plans to Koodo. In Canada, with my new phone, I show small data usage when I am on wifi possibly only when I send a text with a pic and turn mobile data on while on wifi. It appears I am not charged for those texts. I rarely turn mobile data on, even though I now have 2 GB of free data. So costs in Canada not a worry for me with data as I know I won't use all my free data. But I am worried about USA charges for data. I will have mobile data turned off, but want texting on the per use $5/100 outgoing. So, I can't just have Koodo as my network provider on my settings.

I received an email from Koodo saying that someone was roaming on my phone. It happened whe I was in an area, close to the states, but still in Canada. However, there were no charges on my bill. Which I would have challenged because my roaming function was off ( I checked that as soon as I noticed that my phone server had changed, again through an automated note from the American server)

If phone is not used there should be no roaming charges.
This means no cellular data used, no calls made or answered, no texts sent

No. If data is off and no leakage, you will only be charged if a phone call is made/answered or if a text is sent.

I hope I don't have to deal with data leakage complaints every time I go to USA, as I will use texting function, but mobile data will be off. I have a trip soon, so soon will discover whether this happens. I vaguely remember reading, I think, that texts with pics sent from outside Canada generate a data charge, even if you are on wifi when you turn on mobile data to send it???? Presumably the case for an incoming text with a pic too when in the USA? Anyone know ?

Picture message is not included outside of canada and will incur data charges.

If data is off, you will not be able to receive picture messages.  If you dont want to incur roaming charges, never turn on data, even if connected to wifi
