I have sprint but bought a Verizon iPhone?

Now I researched and saw that the iPhone 7+ would be able to accept my SIM card, (which it did) have my bars and LTE and everything. Didn't try surfing the web, but I tried to make a phone call and it say my account could not be validated. What do I do about this?

On KIK messenger if someone is still logged on their app but has the KIK window minimized and I send a message, will it go right to solid D?

I have KIK messenger and if I send a message to a particular person with an Iphone who always has their phone on and logged in (but the window closed/minimized from hitting the home button in spite of them still being logged in), would it still turn to a solid D instead of a faded D because they're still logged onto KIK but their app window is minimized? Is faded D only used if the person has KIK but is logged out?

Will Sprint happen to take less for my leased phone purchase?

So I have a 128gb iPhone 6 I leased from Sprint 2 years ago and its about time to pay it off or give it up and pay for another lease month to month. I have had friends say that through their carriers they were able to keep their leased phone after they pay off 70 percent of the phone. Does sprint work like that or will I have to pay $200 to keep my iphone after the contract ends as stated in the contract
