Your MD300 supports SMS text messaging and the following communications services:
Where UMTS service with HSDPA is available, your MD300 can connect at speeds up to 3.6Mbps.
Your MD300 provides automatic fallback to UMTS where HSDPA is not available and to EDGE or
GPRS service where UMTS is not available (network support required). This section describes the
services that the MD300 supports:

dramatically increased; up to 3.6Mbps using the MD300. File downloads will be faster,
whilst applications such as video streaming may operate at higher quality and greater
reliability. The maximum speed available depends on the configuration of the mobile
network and local conditions such as distance to the base station.
