SIM Card
TROLL Link Telemetry System 100 and 101 units must have a SIM (subscriber identity
module) card to allow communication over the wireless network. TROLL Link 101 units
have SIM cards pre-installed by In-Situ Inc.
TROLL Link 100 customers must obtain a SIM card from their service provider, typically
when purchasing a service plan. These cards can be configured to have a static IP
address. Consider if your application requires a static IP address when purchasing the
SIM card.
Once a SIM card has been obtained, install it in the slot at the top of the TROLL Link
100 modem, as shown below.
