“After I had my Verizon data plan set up, I found it perplexing that the Personal Hotspot button in Settings wasn’t visible,” Sande reports. “”There’s a simple trick to try that will make the button appear if it doesn’t show up automatically in Settings.”
Sande reports, “Normally, once you sign up for a Verizon data plan the Personal Hotspot button appears in the Settings sidebar as you see in the image at the top of this post. For me, it still hadn’t shown up after 36 hours of waiting. The trick to making it magically appear was to go into Settings, tap General, and then tap Network. At the top of this panel is the Personal Hotspot button, which can be toggled on with a tap. Strangely enough, just opening the Network panel also made the Personal Hotspot button in the Settings sidebar visible.”
