Since i started using a chinese sim card in my cellphone, whenever someone calls all that shows is "Unknown caller" or something similar. This happens even when the person is in my phonebook.

So GK'ers, is there a way to pass this or is it just a fact that i will have to live with?

Then go to your telecom outlet and pay a few Rmb to get the Caller-ID 来电显示 lai dian xian shi enabled :-)

Great! so the place where i bought the sim card (carrefour) works? or should i go to some china mobile place? :)

Speaking of calls. Do you guys also get 3-4 calls a day where it only rings once? I assume it's something about calling back and a commercial will play or the number is high rate charged. I'm also sick and tired of the number of txts I get with all sorts of advertisements. Is it even legal?

haha, with the first sim card i had i recieved those advertise-texts all day long. now i have a new one - nothing. never had those calls, but before i used to get phoned by random chinese people just yelling though :o

I asked China Unicom to stop the unsolicited texts. They were quite happy to do so but it did take two requests. They stated that I had 'asked' or signed up for them in the first place, which may or may not be true but it wasn't done knowingly.
I occasionally get 1 ring calls that go unnoticed unti I see them appear as 'missed' calls. They stay missed unless it's someone in my phonebook.

My wife tells me that if you return a call to one of those "one ring" numbers you'll get billed for the call. It really pisses me off that they call at 1:00 a.m. or 6:00 a.m.
