I had upgraded to iPhone 7 about 2-3 weeks ago. I am able to use the hotspot with laptop to connect to different web sites. I can use the VPN to connect to my work computer with home or office Wi-Fi. But I am not able to make the same connection to my work computer when I use the Verizon iPhone 7 hotspot away from home. I called Apple support last week and they referred me to Verizon. Please advise.
