so I've been thinking of ditching my iPhone 6 two years or so from now and picking up an iPad Mini 4 with wifi/data when since its expected to release this year. Now for phone calls I was simply gonna get a Light Phone which is an unlocked prepaid phone. I have t-mobile now. Now I want to keep my same number for the dumb phone which won't be a problem. My wife has an iPhone so iMessage will work for most of the people I text with except my sister she has android but I think I can use other apps? Not sure tho. I know what's app needs a phone number right? Oh well. I really wanna make this work. Any thoughts?
