I upgraded my iPhone 12 to Visible+ and this is how it went. I placed the order on the app 19 Sep. I received a new SIM by noon the next day. I made sure WiFi was enabled and connected. I swapped SIM cards. WiFi stayed connected. Cellular signal bars took about 3 minutes to reappear. I followed the activation steps on the app not the iPhone. I re-enabled AutoPay. I re-enabled WiFi calling. Restarted the iPhone. 5G UW now appears and data speeds are more than twice what they were on 5G Visible Unlimited. I would hope users take the time to post positive experiences. I can't believe everyone's experience is a negative one.
