No maybe about it, reread his original.

And was talking about the opposite, sending as email.

How odd that its labelled send text as email.

But cant be done by him in his dinosaur phone.

Guess again. No evidence that that is even possible and certainly
the manual for his phone says nothing about doing that.

It appears to just be a mechanism to sent text as email as the name
suggests, without any way of receiving a reply to that email etc.

Its possible that the receiver of the email may be able to see the
phone number and service provider of the originator of the email
and be able to use the reverse gateway to reply by email which
will end up as an SMS to the phone of the originator, but the
Nokia manual is silent on that.

Looks very like it was some quirky feature than never did get used
much and its far from clear if anyone actually supports it now telco wise.
