Yeah, it used to be how she kept in touch with her family. Now most of them are on WeChat but once in a while we dust off the credit she still has and use it to call someone she doesn't have a WeChat contact for. The last time we used it the experience was bad--wouldn't stay signed in, multiple annoyances in the way of simply making a call. You don't need to tell us every time that 911 won't trace properly!
