No you cannot. Although there are some phones that support CDMA aswell as GSM.
GPRS (General Packet Radio Service) is considered better than GSM (Global System for Mobile Communications) because it enables packet-switched data transmission, allowing for continuous internet connectivity and more efficient use of bandwidth. This results in faster data speeds and the ability to send and receive data simultaneously with voice calls. GPRS also supports a wider range of applications, such as web browsing and multimedia messaging, enhancing the overall user experience.

Because Boost does not use a GSM network, they use iDEN. Boost phones use a SIM card that is compatible with GSM phones for overseas roaming. However, iDEN is a very different standard from GSM. Most iDEN phones are not compatible with GSM networks, and GSM phones are not compatible with iDEN networks.
