Is there a charge to activate mobile hotspot if you have beyond unlimited?

There is a 15GB threshold, where you get 4G speeds, after you hit the 15GB limit, your speeds will be throttled to 3G for the remainder of your billing cycle. You may also be prioritized during the cycle if the network is congested. This may help you, Beyond Unlimited FAQs | Verizon Wireless
