LTE Mini-Physical Interface Module

The LTE Mini-Physical Interface Module (Mini-PIM) provides wireless WAN support on the SRX300 Series and SRX550 High Memory Services Gateways. The Mini-PIM contains an integrated modem and operates over 3G and 4G networks. The Mini-PIM supports up to two SIM cards and can be installed in any of the Mini-PIM slots on the services gateways.

The Mini-PIM supports the following features:

  • Automatic switchover between service providers through dual SIMs

  • Storage support for multiple service provider and access point name (APN) profiles

  • LTE carrier aggregation

  • SIM lock and unlock capability

  • Always-on, dial-on-demand, and backup modes

  • Over-the-Air upgrade for modem firmware

Antenna connectors

Two SubMiniature version A (SMA) connectors.

Mini-USB port

Mini-USB Type-B port for monitoring and troubleshooting.

SIM slots

Two slots, SIM1 and SIM2, for inserting the SIM cards. The LTE Mini-PIM supports mini, micro, and nano SIMs. The mini-SIM can be inserted directly in the SIM slot. To insert micro and nano SIMs, use the SIM adapters supplied with the Mini-PIM. The Mini-PIM is shipped with two SIM adapters.


SIM cards are not hot-swappable. You must power off the services gateway before removing or inserting a SIM card.
