My understanding reading the post is that there are services that allow you to use SMS using a landline. Businesses can sign up for that, for example, so they can accept texts from customers while still routing voice calls to their landline and into their PBX.I don't understand how having a landline associated to your Fidelity account is a risk.
I have both a landline and cell phone with Fido. On the occasions when SMS didn't work or was S-L-O-W, the "Call me with the code" never failed.
The screen to make this choice does not indicate which phone number is cell and which is landline.
Apparently, the due diligence by phone companies when setting this is up isn't very good, and after an attacker sets it up, they can receive such SMS-to-a-landline routed to them, rather than the SMS simply not going through as with a normal landline. Thus it becomes the new attack vector when phone companies cracking down on the SIM swapping stuff which is the normal SMS concern.
