Can I transfer the SIM card from my broken iPhone 6 to the new one?

Back in May, someone decided to crack my iPhone 6's screen for no apparent reason. The phone has been fine until this morning, my phone fell onto the kitchen floor and the screen completely broke. It's just a black screen so now I obviously have to get a new phone. I was wondering if transferring the SIM card into the new phone will restore all my photos & texts; basically making it the exact same phone. I doubt that everything is on iCloud, I haven't done a back up in a very long time.

Should I get Cricket Wireless?

Does my iPhone 5c have a virus?

I was on some random websites and then I got a message that said (not exact words) warning! You have a virus! Contact costumer support here (phone number)! I did not call customer support, and I do not really want to at all. I have my reasons. But I did look it up on google and the answers I looked at were describing a hack. No one that I know of has got this message. Please please please Please help me:'

If I buy an iphone from Walmart and decide to return it what would happen?

So I bought the iPhone 6 and decided it was a waste of money so I want to return it. I bought it unlocked. What will happen at the return center. I know that they will probably just open the box to check if the phone is there but will they have to take the sim out and check that too and will they need to turn it on. I returned a tablet once but they didn't turn it on they just checked if it was on but is it different with phones. I'm asking this because the battery on the iPhone is dead.

Is Apple Pay and PayPal the same thing?

I'm going to be upgrading from the iPhone 5S to the iPhone 6S. I also do have a Paypal account, but I was just wondering if Apple Pay/Paypal are the same. Actually might switch since Apple Pay sounds easier when you're buying things in-store. But are they the same?

Can I get the new iPhone 6s if I've only had my 2yr contract 1yr?

I got the iPhone 6 last year on a 2 year contract. So it has almost been a year. And I want to pre order and get the iPhone 6s when it come out in 3 weeks. My mom told me that I could do that and they would just renew my two year interact when I went to get the 6s. Is that true? I talked to a support on support chat (online chat) and they said I'd have to pay my way out of this contract before getting the 6s. But I kind think she's wrong. I tried calling. Verizon and they were busy. That's why I'm asking here. But I'll call back later. I also tried to go pre order the 6s online and it said I had to pay the $700 for the 6s to pre order. And that my contract ended a year and week from now.
