5G data roaming is hilarious for this. Verizon offered 500MB of high speed data roaming per day in Canada before throttling down to ~128kbps. I ran one single speedtest in the middle of Ottawa on Rogers 5G, didn't even finish the speedtest (hitting an error at the end that it failed), and got the text message going "You've run out of high speed data today. Do you want to buy another 500MB for $5?"

At least it's 2GB/day now. And my 5G roaming is off...
