If you have a 4G smart phone with Verizon you can turn the hot spot on and off at any time. Not sure about the allowed data use for an individual but on the family plan the entry level is 2 GB/month. For 4 GB add $10, for 6 GB add $20, etc. The best way for us is to start off the month with the basic 2 GB, watch usage and increase the allowed amount as we see it may be needed. When you increase the data during the month it can be backdated to the beginning of your billing date for that month. Our billing date is the 21st of each month. If we see we're about to exceed the 2 GB and are up to 5 GB and it's the 18th of the month we can go online and for $20 raise the allowance to 6 GB and avoid overages. On the 21st we change it back to 2 GB plan.
