Does anybody have a Samsung 4G extender and happy with it? Just currious. I spent hours today, some with a very helpful customer support person, but we couldn't get it to work so in the end I have to send it back. What a waist of my time. I can't find anywhere online, here or elsewhere, a post where someone says there happy with this Samsung 4G extender. My Samsung 3G extender worked pretty well/OK, but because the 3G extender isn't compatible with my new iphone XR LTE phone so I have to change my settings every time I leave the house and also when I return. Not convienient. Thanks!!
