How to use an iPhone in China?

I go to China in 3 months and for a year, and my problem now all the papers are done is about my phone. I own an iPhone 5 and I wanted to know what are the differences of using it in Europe or in China? What about 3G? What about calling? What could you advise me about the phone operator? Having a new one in China or an international plan for my phone?

Get a Bring you own phone plane once you land in China, Iphones are all the same. You will be able to use your iphone 5 just like in Europe. In terms of 3G, you will definitely have it if you live in a city not so much if you go rural. Shanghai is rolling out 4G next month.

While, i'm in China, if your Iphone don't attache a plan with your country's telecome company. You can buy one China's Gsm then use it, well, China everywhere sell Iphone5, please don't care for use it, and we often buy europe mobile and use in China. 3G is Ok, everything is Ok!

Hi, to give you some hints. If your phone is unlock, meaning not locked to one provider say Verizon, Rogers etc. Then you may use anywhere in China, all you need to do when you get to China, buy a simcard there. And use it. If it is locked, get it unlock before you travel there. In China, there's no international plan, and even if you get an international plan from your country, it will be very expensive for roaming. I don't know which country you are from, In Canada, it is easy to get iphone unlock.
