I'm heading to China in a couple weeks, and will be there for half a year. I'm a bit of a noob when it comes to networks and all. Can I use it in China, subscribing to a chinese service like China unicom? I know you can buy sim cards. But I'm confused 'cuz the sim card in my phone is a verizon LTE. And LTE is not available in China (or not widely). I know you can get a 3G sim card.
Anyway, I'm wondering... can I go to china, buy a sim card (correct size of course) and stick it in the sim card slot and use my phone?
