So where my girlfriend and I live we have terrible phone service. We called tech support and the suggest we turn on wifi calling on our note 5's. Sadly this has done nothing to help. I have 75mbps internet and according to speed test.net I do actually get that speed on my phone. Now not only are calls choppy and drop constantly in our home, but the phones are Andy's looking for wifi so we have problems on the go to. Is there anything else we should be doing to get wifi calling to work expect turning it and hd calling on and being on wifi?
