Data not working on sprint Iphone 6s plus?

Added (1). I got an iphone 6s plus with sprint about two weeks ago. I decided to only get the 1 gig of high speed data for now to see if i could afford more later on. What the lady at sprint told me was that i would have 1 gigabyte of 4G LTE coverage adn once that was used up i'd drop to 2G coverage. I haven't even used all of my 1 gigabyte; so far i've used 987 MB, but my data isn't working at all. It shows the "LTE" logo, but i'm not able to connect to anything.

How to I restore my new iPhone after it is set up?

I switched carriers (from Sprint to T-Mobile) and kept the same IPhone model just different phones (iPhone 6s). I understand that it gives you the option when you re setting the phone up initially with the basic prompts to set up as new phone or restore using iCloud backup. The thing is, I'm not able to choose the iPhone backup I already have saved because it needs iOS 9.2 or higher. This can't be accomplished until after I set up the phone and can choose to do the software update from the iOS 9.1 to 9.2. I tried resetting my phone already and it always gives me the same prompt (backup requires iOS 9.2 or higher).

My phone is set up as a new phone, but I want to restore it using iCloud backup.

Should I get a iPhone 6/6s or wait until iPhone 7?

So this my plan. I'm under contract with my iPhone 4 until August 25th this year. But I could only afford the 16gig version of a iPhone 6s. But I was thinking of waiting for the iPhone 7 next year because it could better. The s version of I iPhone is a waste of money. So I would wait until next year but my iPhone 4 is so crappy I was thinking of buying a iPod 6 so I can use that until next year. 32 gig version of the iPod. Is this a good idea?

Apps are deleting themselves from my iPhone 6s?

I know this was stupid, but… I was on a school field trip to New York City a couple of weeks ago and I found some free Wi-Fi and STUPIDLY logged on. A lot of my apps then preceded to try and redowload themselves! And it just happened again…
Could I have a virus? If so, how can I get rid of it and stop my apps from messing up again?
