Turbo Hotspot 2

I want to buy a turbo hotspot 2 and a data plan. The choices are

1. I’m switching to cricket,

2. I need a new number, or

3. I’m upgrading my phone. 

Of course, none of those are accurate so which one do I choose? What does each one mean?

Can I add extra hotspot data to my data only plan like I can with my phone’s mobile  hotspot if needed?

Can you give instructions for buying and setting up the hotspot beginning to end? That would be very helpful.

Is there a way to make my phone and data only plans come due for payment on the same day of the month?

Thank you.

This page is forcing me to choose a subject but won’t let me choose phones and devices, which is accurate. None of the devices listed is a hotspot so I can’t choose an accurate subject, it’s forcing me to choose something inaccurate. Why don’t you make your website clear? Then I wouldn’t even have to be writing here to get information.
