You can get a free phone number from Google that you can use:
With Google Voice, you get a free phone number for calls, text messages, and voicemail. You can use the apps on smartphones and computers, and you can link your number to any mobile or landline number.
Thanks so much for the reply. I've searched and find that the advice couldn't be done because Google's own site for acquiring a Google phone number states, "Voice is only available in the U.S. If you're outside the U.S., you can make calls with Hangouts.". I'm still not sure how to go about this.
