SIM Card Slot
The SIM card slot is located to the right of the LED Display Panel inside the battery compartment. It enables
you to install a standard SIM card into the receiver. Once installed, the SIM card provides a unique identification
for the receiver’s HSPA module and enables the receiver’s HSPA functionality based on the subscribed services
(the receiver board accesses the HSPA module, which accesses the SIM card). The SIM card usually remains
inside the receiver. You can access the HSPA module, with the SIM card installed, via SRU for configuration
purposes. A SIM card can be purchased from a local cellular provider.
SIM Cards
The SIM card must have HSPA support to communicate over a TCP/IP network.
Installing the SIM Card
1. Make sure the receiver is turned off.
2. Remove the detachable battery to the right of the LED Display panel.
3. Carefully insert the SIM card, label-side up, into the SIM card slot located at the top of the battery
compartment.
Once the receiver is turned on, the receiver board will detect the SIM card, and it will be ready to use as
needed.
The Sokkia Atlas receiver, equipped with a CDMA module, does not require a SIM card and is only
approved to work on a Verizon®wireless network. Note the MEID# printed on the Sokkia Atlas unit
or extracted from SRU, and call Verizon to activate service on the CDMA module installed on the
receiver.
The CDMA module is available on-demand in the United States only. Contact your Sokkia dealer for
more information.
