I have an iPhone 6 (cdma) running on tracfone byop. I can't use my data on it

I have an iPhone 6 running on IOS 10.2.1 It is a Verizon (cdma) phone, anyways, I used tracfone's byop plan and set it up on that. It can make calls and send texts just fine, even access the internet via Wi-Fi. However, if I try to access the internet via cellular data, it gives me a message saying to turn on cellular data in settings, even though it is already on. Every once in a while when I go somewhere out of town, we will drive through an area without service and then when I get back into service the data works for a couple minutes and I can access the internet with it. Then it reverts back and It won't work anymore. It is driving me crazy, can someone help me figure it out?

If greed is so natural to us, then why do we have to be taught it from a young age?

Why do teachers have to tell us not to share our answers to questions for example?

Why do parents bombard their kids with expensive presents and stop them from playing with the wrapping paper?

Why are we sneered at as parents for not buying our child the newest trainers or IPhone?

Our humanity is sick with a disease, the disease of greed, consumerism, and ownership, we're conditioned to ignore the plight of our fellow man, to ignore our natural instincts to help him, because we're told in order to be a good upstanding "successful" member of society that we just need more and more stuff for ourselves, and to become greedier and greedier. We hoard for ourselves, and forget the plight of our brothers and sisters, working crazy hours at jobs we don't like so that we may squirrel away yet more and more, yet for what, when we don't even get to take it with us.

Will StraightTalk work with a US Cellular phone?

I recently started using straight talk for my phone carrier but I've been using an iPhone 5, and a person is selling a 6+, but it's a US Cellular phone. Would straight talk allow me to bring it over? I know that the phone is paid off and can be unlocked.
