Google preps a friendly reminder that phone calls work on more than just mobile networks

Did you know a mobile network isn't the only way to make phone calls? You can also phone a friend via Wi-Fi. This is particularly helpful in areas with weak or no mobile network coverage, especially as we wait for satellite connections to become more widely available. Wi-Fi calling exists, but it's usually a feature that you need to enable on your phone. And, unless your phone automatically does it for you, you might not remember to enable it in times of need.
