No, GSM and GPRS only. A SIM card is not specifically 3G. That depends on the network providers usage of SIM cards. Most providers will allow handover between 3G and GSM cells thus allowing GSM usage. The network provider may also allow roaming and handover to another networks for better coverage. 

Check if your network provider has restrictions on the GSM/GPRS internet connection for the SIM.
