How do I get hotspot
Are you talking about using your phone as a hotspot, or buying an independent mobile hotspot?
If it's the first situation, you need to make sure your service plan includes hotspot capability. Then it's just a matter of turning on the hotspot feature on your phone. If your phone is a Verizon variant, there's plenty of troubleshooting/user guides available on the Verizon website, but you will have to login to your account in order to view the specific guide for your phone. Or an internet search will tell you how to enable the hotspot feature.
If it's the second situation, you would need to purchase a mobile hotspot device either from Verizon, or obtain one which is compatible with Verizon, then purchase a hotspot service plan from Verizon.
