iPad Air cannot connect to Verizon account

Is anyone else having this problem and if so how did you fix it? I have an iPad Air with a brand new Verizon SIM in it. When I first installed this SIM I was able to create a new account, get a data number for the iPad, and establish my data plan (currently I use the $5.00/day plan and only get it when I need it since I normally connect via WiFi at home and work). This worked fine. However, after the $5.00/day plan expired (like the next day), I was no longer able to use the View Account option on the Settings -> Cellular window to "purchase" more $5.00/day plans or ANY plan. I can log in to my Verizon account and see my info such as address and payment information, but it will not show me plans, usage, etc. When I do click Change/Add Plan, it just "spins" and tells me to "Please wait". Nothing happens. This also happens if I try to do it with WiFi turned on.

This used to work with my previous SIM. I could log in, pick a plan, get activated, etc. without having to call a Verizon rep. I would like for it to work this way again. I have called Verizon about this numerous times. Sometimes they are clueless, sometimes they have me do various things on the iPad to no avail, and others they tell me that Verizon is updating some of its applications and that I will not be able to do this on the iPad. They cannot give me a date as to when this will be finished. Often they tell me just to try it again in a day or two. This has been going on for two months. It's obvious no one has any idea what the problem is. Does anyone here have any ideas?

Note I posted this to the Verizon forum and customer support responded I should reset network settings and/or reset the whole device. I did both and it did not change anything. They then told me to call prepaid support and further help. That's what I have been doing for the last two months.

Thank you,

David
