Has anyone used a virtual phone number service like flynumber.com or freedigits.com? A sibling who lives in the UK has a holiday home in Ireland and needs an Irish phone number to sign up for a number of things. Looks to me like flynumber.com with let them get a Dublin landline number and forward it to their UK phone, or even to a VoIP service (which they already have) for free. Just wondering if anyone has tried it or something like it, and how it worked out?
