Q:

Selectively force Siri to send SMS instead of iMessage

I carry an iPhone.  On occasion, I will use Siri to send a quick text message to a person, e.g. "Text Alice I'm on my way."
My problem is that Alice has a non-Apple phone and an iPad, and I've used both SMS to communicate with her phone and iMessage to communicate with her on her iPad.  If I'm using the Messages app directly, I can pick either the SMS conversation or the iMessage conversation, but if I say "Text Alice," it seems unpredictable which mode of communication Siri will select.
Annoyingly, even if I say "SMS Alice," Siri can choose iMessage.  Is there any way to specify which mode I wish to use?

A:

For SMS, tell Siri "Text Alice on mobile I'll be right there."
Alternatively, you can set up two different contacts for Alice, one for SMS and one for iMessage and then tell Siri which one to use be citing the different names.
