Where should I get my iPhone?

I've been wanting to upgrade for some time now!
I want the I phone 6 plus
But I don't know what company I should get it from?
I want to buy it from a company that makes me pay for it monthly but where will I be more satisfied buying it from?
On the day I get it how much will I end up paying for it that same day?
How much will I end up paying monthly, with unlimited talk and text and internet connection?

You can get it anywhere. T-Mobile, Verizon, anything. (Verizon is best) If you don't want to pay monthly then just get it all at once. There are plenty of options for you to choose from

I recommend Verizon. I bought an iPhone 6 last week and I traded in two old basic phones for 100 bucks each and since my brother and I were both getting iPhones we were able to grab an iPad for like 90% off which was a pretty chill deal IMO. I'm not sure on the prices for the 6 Plus but my brother and I are paying like $25 a month each for a two year contract.

You'd have to compare the rates, plans, coverage of the carriers to make that decision.

For the record, except for T-Mobile, no unlimited data connection (think Sprint as well).
