Chip SIM
For devices utilizing a physically soldered down chip SIM, consider what network or networks the
device will connect to. More specifically, beyond the obvious intended end network(s) the device will
deploy on, keep in mind the need to connect with a test network or base station simulator call-boxes,
which may require a specific UICC profile to connect to. Anticipate such needs and be prepared to be
able to obtain and configure a profile to connect to such networks or simulators.
Alternatively, here below some other possible ways to proceed for testing purposes:
•
Configure a device(s) with a SIM card holder for physical removable SIM for such engineering or
pre-production activities.
•
Make sure to disable authentication and integrity checks on the tester side (by proper setting) and
on the module (by using the
AT+UDCONF=81,0
AT command, see SARA-R4 series AT commands
