Data connections
GSM data calls
A GSM data call enables data transmission rates of up to
14.4 Kbps. For availability and subscription to data
services, contact your network operator or service provider.
High-speed data calls (High Speed
Circuit Switched Data, HSCSD)
HSCSD enables data transmission rates of up to 43.2 Kbps,
which is four times faster than standard data rates of the
GSM network. HSCSD is comparable to the speed of many
computer modems that communicate with fixed telephone
networks.
For availability and subscription to high-speed data
services, please contact your network operator or service
provider.
Note: Sending data in HSCSD mode may drain the
device’s battery faster than normal voice or data calls,
as the device may send data more frequently to the
network.
Packet data (General Packet Radio
Service, GPRS)
GPRS enables wireless access for mobile phones to data
networks (network service). GPRS uses packet data
technology where information is sent in short bursts of
data over the mobile network. The benefit of sending data
in packets is that the network is occupied only when
sending or receiving data. As GPRS uses the network
efficiently, it allows for quick data connection set up and
fast data transmission speeds.
You need to subscribe to the GPRS service. For availability
and subscription to GPRS, contact your network operator
or service provider.
(E)GPRS (Enhanced GPRS) is similar to GPRS but the
enables faster connection. For more information on the
availability of (E)GPRS and data transfer speed, contact
your network operator or service provider. Note that when
you have selected GPRS as a data bearer, the smartphone
uses (E)GPRS instead of GPRS if this is available on the
network.
Pricing for GPRS and applications
Any data transfers via GPRS and (E)GPRS are subject to
applicable operator data transfer fees. For more
information on fees, contact your network operator or
service provider.
Access points
A data connection connects your smartphone to the
Internet via an access point. Your smartphone supports
three kinds of data connections:
• GSM data call ( )
• GSM high-speed data call, or HSCSD ( )
