SIM Card
The 3631 telephone supports a SIM card for storage of a subset of configuration and user
data.
The SIM card is useful in shift environments. Each shift user may have his or her own
SIM card that can be inserted/removed from phone at the start/end of the shift. Each
individual SIM card can be used to store a single user’s personal information such as
their extension and private contact numbers.
A SIM card also facilitates provisioning of a replacement 3631 telephone. Users may
remove the SIM card from their malfunctioning phone and re-insert it in their new phone.
Thus, WLAN connectivity information and (basic) contacts information from the
previous phone is preserved in the new phone.
By assigning an optional PIN to a SIM, a user may limit the use of a lost/stolen phone.
See the “SIM Card Security” section for more details.
Note:
The 3631 telephone has limited functionality without an installed SIM card. For example,
the phone can associate only to discovered APs without security.
Data Stored on SIM Card
The following data is stored on the 3631 telephone’s SIM card:
• Access Profiles
• Extension and Password
• Contacts
– Limited data: just name and single number
• Country
SIM Card Security
A 4-digit PIN code may be assigned to the SIM card. The PIN code is optional and may
be disabled through phone user interface.
The user is prompted for the PIN at the startup of the phone. The user must enter the
correct PIN code to proceed with the startup process. The default PIN is 1234 ; although,
the user may change the PIN through the phone user interface.
Three incorrect PIN attempts in a row disables the SIM card. These attempts may occur
over successive startups.
A disabled SIM card may be re-enabled through the PIN Unblocking Key (PUK) process.
In this process, a PUK code is required to re-enable the SIM card. A user must enter the
PUK code into phone to re-enable the SIM. After 10 unsuccessful PUK code entry
attempts, the SIM card is permanently disabled and must be replaced.
