If your 2SV via SMS reference (also) refers to WhatsApp:

2SV via SMS is only used during registration, not during normal use.
And it's optional, another method is to get the 2SV code via an
automated voice call [1]. That's how it done for a landline [2] number
or/and SIM-less device and the same method can be used for a 'normal'
device, i.e. mostly - but not limited to - a smartphone.

[2] The WhatsApp Help Center implies that landline number are no longer
acceptable for regular users, only for WhatsApp Business.
