Hey guys, it's my first time posting on here. Was wondering what's the cheapest iPhone 5s carrier out there? (I also need to buy an iPhone up front). I'd like unlimited data/text/calls but can be very flexible on the text and calls.
Right now I'm leaning towards Ting, where you can configure your own plan based on your needs. It's $40/month, no contract (woo!) and the phone would be $260. Any other suggestions? Thanks so much!
