Voice and Data Communication

Dolphin terminals with integrated GSM/HSDPA/UMTS/GPRS/EDGE radios are optimized for the following two-way voice and data communications:

Voice: GSM voice data (dial-up)

Data: Available speed depends on the wireless network carrier and their supported packet-data technology in addition to network conditions.

GPRS Class 10: data transmission max. 85.6 kbps (DL), max. 42.8 kbps (UL)HSDPA: data transmission max. 3.6 Mbps (DL), max. 384 Kbps (UL)UMTS: data transmission max. 384 Kbps (DL), max 384 Kbps (UL)EDGE (E-GPRS) Class 10: data transmission max. 237 Kbps (DL), max. 118 kbps (UL)

You can use the GSM radio for voice communication and data communication but not at the same time. If you want to communicate over the phone (voice), you cannot send data. If you want to send data, you cannot use the phone.
