• Topcon GRS-1 receivers are available with either an internal GSM or
CDMA modem. Only GSM modems use SIM (Subscriber Identity
Module) cards. CDMA modems do not have SIM cards.
• Using either modem type, it is common to describe to the cellular
provider that you need a, “No Obligation / Unlimited data plan (no
voice).” Tell the sales representative that you have your own
hardware.
