The initial implementation of 3G networks enables Internet or corporate
network access at bidirectional data rates of up to 384 kbps.

2G
GSM/GPRS coverage is available in almost all populated areas of the world
and provides a secure fall back so that network connection is maintained.
2.1.2.1
GPRS
GPRS is an enhancement to GSM networks and provides packet data
transmission. The connection setup is fast and, once connected, applications
may send and receive data whenever required.
C5621 and C33 are using GPRS with Multislot class 10, which enables
communication speed up to 100/60 kbps (DL/UL).
2.1.2.2
EDGE
EDGE (Enhanced Data rates for Global Evolution) is an integral part of the
GSM family of open mobile standards. EDGE improves GPRS by increasing
data throughput by a factor of three. GPRS networks enhanced with EDGE
are often referred to as E-GPRS (Enhanced GPRS) networks.
C5621 and C33 are using E-GPRS with Multislot class 10, which enables
communication speeds up to 296/177.6 kbps (DL/UL).

C5621 and C33 can send and receive text messages. Facilities such as copy
and paste make it fast and easy to send information via text messages from a
computer. The standard maximum length of a text message is 160 characters,
(dependent on character coding), but since concatenation is supported,
messages longer than 160 characters can be sent and received.
