I had an iPhone 5s for a week with Verizon and it was great. Then my dad said it was too expensive so now I don't have a phone once again. He said if I get another iPhone, it has to be with Sprint. Nope, not doing that.
AU by KDDI. It's a Japanese cell phone company. Works well and I managed to get on a cheap plan. The only thing that sucks is that you pretty much have to be on a contract for cell phones in Japan. And the contracts are always 2 year increments. If you want to get out of the contract early, you have to pay a cancellation fee that can be pretty high.
