Changing the SIM in a BANDIT™
Product’s GSM Card
ireless connections use radiofrequencies (RFs) through airwaves instead of electrical
signals through cables. A wireless connection obviates the need to use cables; it also
allows free physical movement within the broadcast radius of a wireless access point
(AP)—for example, a cell tower.
Most BANDIT products can support a wireless card that uses Code Division Multiple Access
(CDMA) technology or Global System for Mobile Communications (GSM) technology.1 This
document discusses replacement of a Subscriber Identity Module (SIM) in a GSM card.
Note: For information on how the BANDIT products use wireless technology, including
activation and configuration of wireless cards, see Activating a Wireless Card in a Carrier Network.
B.1 The GSM Card’s Subscriber Identity Module
A GSM card, for connection to wireless networks that use the GSM technology, supports a
removable SIM (also known as a GSM smartcard) to identify the user to the GSM network. When
you order your BANDIT’s wireless card, you specify which carrier and network it will use. This
specification also indicates a SIM that has the selected GSM carrier’s chip.
The BANDIT is not a traveling device, so you will not need SIMs for different countries. However,
if you change GSM providers, the GSM card will need a SIM from the new provider. To change
the SIM, use the following procedure.
How to Install or Replace the SIM in a BANDIT Product’s GSM Card
Note: If you are replacing the entire wireless card, do not use this document; instead, see
Changing the Card in a BANDIT™ Product’s Expansion Slot.
1. All BANDIT chassis that use wireless cards can support the following technologies:
• GSM using General Packet Radio Service (GPRS GSM)
The BANDIT II and the BANDIT III can also support the following technologies:
• CDMA Evolution, Data Optimized (EVDO)
• GSM using Enhanced Data Rates for GSM Evolution (EDGE GSM)

Warning: Follow all precautions against electrostatic discharge (ESD) when removing
or installing modules in a BANDIT device. (For example, wear an ESD wrist-strap to
protect the unit from ESD.) Allow only qualified service personnel to install and
maintain this equipment. See Basic Safety Guidelines.
To prevent electrical shock, do not power on the equipment until all cables are
! Caution: After you replace the SIM, you must activate the GSM card in the carrier
1 Unplug the BANDIT device’s power supply from the power source.
2 Disconnect all network connections.
3 If this is a BANDIT Plus chassis with a cable to a Remote Data Unit (RDU), disconnect
that cable from the BANDIT Plus chassis.
4 If this is a BANDIT Plus chassis, loosen the retaining screws holding the chassis to the
equipment rack, and remove the chassis from the rack.
5 Place the chassis on a flat, stable surface.
6 Do the following:
a Remove the screws from the bottom of the chassis. (There are four screws on the bottom
of a VSR-30, original BANDIT, BANDIT III, or BANDIT IP chassis. There are six screws
along the bottom of a BANDIT Plus chassis.)
b If this is a BANDIT Plus, remove the screws along the top of the chassis.
7 Do one of the following:
a Lift the top off the VSR-30, original BANDIT, or BANDIT IP chassis (Figure B-1).
b Lift the top off the BANDIT III chassis (Figure B-2).
Note: The BANDIT III uses a daughterboard only if the chassis has an Internal Data
Unit (IDU)— four DB25 serial ports along the top of the backplate. For information on
the BANDIT III chassis, see the BANDIT III™ Hardware Description.
c Slide the front faceplate and chassis bottom of the BANDIT Plus forward, out of the
chassis frame (Figure B-3).

8 If this is a BANDIT III, lift the motherboard-and-daughterboard assembly out of the
chassis base (Figure B-4). Set the assembly on a stable work area. (The motherboard is
the lower card in the assembly. The daughterboard, if present, is the upper card in the

9 Do one of the following:
a On BANDIT devices other than the BANDIT III, locate the SIM socket on the top of the
GSM wireless card (Figure B-5). It should have a SIM in it. Continue to Step 10.
! Caution: Leave the GSM card in place, and leave all of its connections in place. There is
no need to move it.
Figure B-5. GSM Wireless Card (in a Chassis’s Expansion Slot)
b If this is a BANDIT III, turn the motherboard–daughterboard assembly over. The SIM
sockets used for GSM cards are on the underside of the BANDIT III’s motherboard
Note: On the underside of the BANDIT III motherboard, the SIM socket closer to the
BANDIT III’s expansion slot is used for a GSM wireless card (if any) in the expansion
slot. The other SIM socket is used for the BANDIT III’s internal wireless card (if that
card uses GSM technology).
Each SIM socket on the underside of the BANDIT III motherboard should hold a SIM if
there is a GSM wireless card in the corresponding position in the BANDIT III chassis.
In a BANDIT III, the SIM socket on the top of each GSM wireless card should be
empty; that SIM socket is not used.
! Caution: There is no need to look at a GSM card in the BANDIT III unless you are
replacing that card. Each wireless card in a BANDIT III is attached to the motherboard
and can be reached only by disassembling the motherboard–daughterboard assembly.
Do not disassemble that assembly unless you are replacing a card in the expansion slot.
If you do need to replace a card, see Changing the Card in a BANDIT™ Product’s

10 Note that the SIM socket has a latch to unlock or lock its door. The latch should be in the
locked position (Figure B-7). For the SIM socket, do the following:
When the SIM-holder's door is locked, the flanges
of the lock are under the catches.

a Slide the metal latch toward the end of the SIM socket’s door (Figure B-8). You might
hear a slight click when it unlatches (Figure B-9).

c If a SIM from a former GSM provider is in the door, slide it out (Figure B-15). (Use care
not to touch the contact pad.) Put the old SIM into an anti-static bag.

d Open the package holding the new SIM. Hold the new SIM by its edges and take it out
of the package. (Figure B-16).
Note: The SIM has a notch out of one corner, to fit into the beveled corner of the SIM
socket. The SIM will fit into the socket in only one way.

! Caution: Be careful not to touch the contact pad on the back of the SIM (Figure B-17).

e Make sure the SIM’s contact pad will face the contacts in the bottom plate of the SIM
socket when the door is closed. Then slide the new SIM into the door (Figure B-18
through Figure B-20). (The door has guides to hold the card in place.)

! Caution: The SIM fits into the SIM socket in only one way. When you gently swing the
door shut, you will see whether the notched corner of the SIM fits into the socket’s
If the SIM is not in the correct position, its notched corner will not match the beveled
corner in the SIM socket, and the door will not close (Figure B-24 and Figure B-25). In
that case, remove the SIM and replace it in the correct position (Figure B-26).

11 For the BANDIT III: Turn the motherboard–daughterboard assembly rightside up, and
place the assembly onto the bottom of the chassis.
Note: Do not use the chassis top. The chassis bottom has rubber feet (Figure B-29).
Figure B-29. Bottom of BANDIT III Chassis
Note: The front and back bays of the BANDIT III chassis bottom are the same. The
motherboard–daughterboard assembly will fit into the chassis bottom regardless of the
bay that you choose as the front.
12 For any BANDIT device, do one of the following:
a Place the top back onto the VSR-30, original BANDIT, BANDIT III, or BANDIT IP
Note: The top of the chassis will fit in only one direction. One side has a tongue and
the other side has a groove, to fit the groove and tongue on the corresponding sides of
the bottom of the chassis.
b Slide the BANDIT Plus chassis back together.
13 If this is a BANDIT Plus, tighten the screws on the top of the chassis.
14 For all BANDIT devices, tighten the screws on the bottom of the chassis.
