CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.1.9 SIM/APN/Auth Settings

SIM PIN: PIN number for a GSM modem with a locked SIM.

Authentication Protocol: Set this only if your service

provider requires a specific protocol and the Auto option

chooses the wrong one. Choose from Auto, PAP, and

CHAP and then input your username and password.

Access Point Configuration: Some wireless carriers

provide multiple Access Point configurations that a modem

can connect to. Some APN examples are ‘isp.cingular” and “vpn.com”.

• Default: Let the router choose an APN automatically.

• Manual: Enter an APN by hand.

• Select: This opens a table with 16 slots for APNs,

each of which can be set as IP, IPV4V6, or IPV6. The

default APN is marked with an asterisk (*). You can

change the APN names, select a different APN, etc.

For Verizon modems, only the third slot is editable.

Changes made here are written to the modem, so a

factory reset of the router will not impact these

settings.
