Unlock a SIM card
A SIMcard can be locked if a user tries to set an invalid PINfor the SIMcard too many times. In
addition, some cellular carriers require a SIMPINto be added before the SIMcard can be used. If the
SIMcard is locked, the TransPort device cannot make a cellular connection.
Command line
To unlock a SIM card:
1. Use the show cellular command to see the status of a SIMcard. In the show cellular output,
look for the fields SIM1PIN status, SIM2 PINstatus, and SIMstatus.
2. Use the unlock command to set a new PINfor the SIM card using the following syntax:
unlock <sim1 | sim2> <puk code> <new sim pin>
For example, to unlock a SIMcard in SIMslot SIM1 with PUK code 12345678, and set the new
SIM PIN to 1234:
digi.router> unlock sim1 12345678 1234
3. Save the configuration.
digi.router> save config
Note If the SIMremains in a locked state after using the unlock command, contact your cellular
carrier.
