3.8 Locks
Use Locks to restrict access to specific GSM operators and/or a specific SIM card.
When a lock is defined, the Gateway will only register to an operator network or
allow a SIM card that matches the Lock number.
In addition, use Locks to prevent roaming handover in cases where the Gateway is
located close to county or country borders.
To define a Lock number:
1. Ensure that:

you have obtained the codes from the cellular operator

the cellular modules support SIM locks
2. From the Cellular Cards branch of the HMC navigation pane, click the Locks
sub-branch. The Locks screen is displayed.

entered.
