Update 4: @BradinToronto shows a screenshot of getting 6Mbps using Personal Hotspot on Fido in Toronto.

Update 3: Confirmed to work with Bell as well, via HDStig in the comments.

Update 2: More info from acfusion29:

it just says wi-fi password and i have to enter a password that’s at least 8 characters.

no WPA/WPA2/WEP options as far as i can see.

Update 1: Fido too. There’s only 1 bar of signal though. Thanks @iRuni_ !

Anyone else have this working on Telus/Bell?
