Is it easy to get a SIM Card in China with a foreign passport?
I would need it to do some phone calls and mainly to have internet access. Something like 5GB should be engough.
Which carrier has got the best coverage in Yunnan, Chengdu, Chongqing, Hainan?
Is such a SIM good for Hong Kong as well?
My mobile has:
2G: GSM 850/900/1800/1900MHz
3G: WCDMA 850/2100MHz
Is there maybe a webpage where can see the coverage of the different providers?
1. Yes. You can either get it at the big official shops and have it registered to your own passport or you can just buy one at places on the street and I have no idea who they're connected to.
2. China Mobile probably. If you're leaving the city a lot, definitely China Mobile.
3. Doubt it.
I actually have china Unicom because I can get 3g with my iPhone. there's something weird with iphones and 3g on China Mobile.
Checking the carrier sites directly might get you a coverage map. I don't know of one that compares them.
Okay, so if I buy a card at a 7/11 or something, are the instruction only in chinese or in english as well?
Are there any price differences depending on where I buy the SIM card?
