Connecting to your cellular
provider
The PinPoint X uses your cellular provider as an ISP (Internet
Service Provider) to connect you to the Internet.
Steps of a connection:
1. When your PinPoint X is powered on, it automatically
searches for cellular service using HSUPA/HSDPA.
2. Your PinPoint X establishes a PPP (Point to Point Protocol
or “dial” up connection) link to the your cellular provider
network, also called registering on the network, and
receives an IP address.
3. When your PinPoint X has received its IP address from
your cellular provider, a connection to the Internet or the
cellular network is also available for computers or other
devices connected directly to the PinPoint X.
