Cellular Data Plans
Cellular provider plans are required for cellular modem provisioning, which usually refers to
M2M plans. For new systems, Neptune recommends starting with a large (2-GB to 4-
GB/R900 Gateway, or unlimited) data plan, until usage is assessed after several months. MIU
and R900 Gateway installations can create added usage at project start.
It is possible to provide an estimate; however, the cellular account holder is responsible for
any overage costs. Some carrier plans include pooling multiple cellular devices into one large
bucket of data, so make sure bucket equals the number of R900 Gateway multiplied by 4-GB.
The carrier could require a SIM card or the IMEI, ESN, or MEID from the cellular modem to
add to the account and provision. The IMEI, ESN, or MEID are provided to Project / Utility
Stakeholders after R900 Gateways are shipped from the manufacturer so the carrier can
complete the account setup and provisioning. If R900 Gateway static IP addresses are
desired for implementation, request them from the carrier during setup and provisioning.
GPRS carriers with SIM cards often have different APNs for static and dynamic IPs. The carrier
can provide a list with static IP address details for each modem and SIM.
