This SIM obviously has an IMSI from Three's Hong Kong 3G network (see http://en.wikipedia.org/wiki/Mobile_..._China.29_-_HK) but I assume that this SIM can also register on Three's Hong Kong 2G network. However if this particular SIM with an identity from the 3G network registers on the 2G network (which has a different network code), your device assumes it is roaming on a foreign network (because of the differing network codes) and so it probably wouldn't automatically establish a data connection in order to protect you from potentially high charges (which usually apply if you use another network than your home network). But in this particular case I assume that there wouldn't be extraordinary charges as you would use the same operator despite this technical difference so you would just need to manually connect by pressing the "connect" button.

May I ask... If the SIM is a Mobile broadband, it will be fully compatible with Huawei e583c?

I can't tell you. Only your operator can say if your SIM is beind admitted to his 3G network and if it is eligible for data tariffs.
But you should know Three's configuration in Hong Kong and Macau (different network codes for their 2G and 3G network) is rather unusual. At least in Europe operators use the same network code for their 2G and 3G network, so our devices don't "think" they are using a foreign network once they switch from 2G to 3G or vice versa. With a TIM SIM card your device will consider TIM's 2G and 3G network as its home network and will automatically establish a data session.

So, TIM "Internet Senza Limiti" is absolutely matched Huawei e583c device? Just simply set the apn "ibox.tim.it" will be connected automatically, no need to connect manually, right?

Yes. Your E583C should work flawlessly on the TIM network and it will automatically connect unless you have disabled automatical connection (in this case you would just need to press the "connect" button). TIM uses GSM900 and GSM1800 for its 2G network and UMTS2100 for its 3G network - all supported by your E583C.
