Carvin S400 manual Using the 3G Feature Optional, Installing a SIM Card

Using the 3G Feature (Optional)

3G is the third generation of mobile phone standards and technology after 2G. Services include wide-area wireless voice telephony and broadband wireless data, all in a mobile environment.

Unlike IEEE 802.11 networks, 3G networks are “wide area cellular telephone networks” which evolved to incorporate high-speed internet access and video telephony. IEEE 802.11 networks are short range, high-bandwidth networks primarily developed for data.

NOTE: Your model only supports data transmission, voice transmission is not supported.

Installing a SIM Card

To use the 3G feature to connect to the Internet, you need to subscribe to 3G service and acquire a SIM card from the service provider. To install the SIM card, follow these steps:

1.Turn off the computer and disconnect the AC adapter.

2.Remove the battery pack. (See “Replacing the Battery Pack” in Chapter 3 for instructions.)

3.Insert the SIM card into the holder. Make sure the golden contact area on the card is facing upward and the beveled corner on the SIM card facing outward.

NOTE: To remove the SIM card, push inward to release and slide the SIM card out of the slot.
