So here's what I have:
Primary phone line: iPhone 7 with Simple Choice Family Plan (unlimited for my line)
Tablet: iPad Mini 4 with 6 GB Plan
Home Location: Chicago
I have the DIGITS app on my iPad and have it linked to my iPhone and can make calls and text using the DIGITS app. Pretty cool in case I don't have my iPhone on me. Basically can leave the iPhone at home and take the iPad with and make/receive calls and texts using my iPhone's phone number. Pretty slick.
What I am wondering, is if I am out of the country (say, in Canada) can I basically leave my iPhone off and just use my iPad to get phone calls? I know while roaming I get free data and text messages, but phone calls are $0.20/minute. Not the worst expense in the world of course, but I was just wondering if I kept my iPhone OFF, could I make phone calls over the iPad (using the DIGITS app) and not get charged? Worst-case, I'll just make calls over Facetime or Hangouts. Thanks!
Great question! The DIGITS app has you covered when roaming internationally. However, slower data speeds may cause intermittent issues. Calls and texts made from the DIGITS app follow the same rules as your number does for calls or text messages made internationally. So the charges if any will be dependent on your plan and would be the same if you were using your iPhone.
