Appendix 2 Requirements for the SIM Card
PIN Locked SIM Cards
Supported SIMS and Networks
Please refer to page 31 ‘Modem Approval and Certifications’ for a list of Networks supported by Optimus
Cloud.
Some SIM Cards are supplied with a PIN code that needs to be entered before a connection is made to the
cellular network.
The CK685 does not support PIN locked SIM cards and the PIN has to be removed from the SIM before it may
be used in the outdoor kit.
To do this, the SIM card should be inserted into to a suitable mobile phone/handset and the PIN or SIM Lock
disabled.
Connecting via Optimus Cloud
By combining Optimus Cloud with an industry-standard modem with multi-network certifications, a standard
SIM card with a data connection can be used in the CK:685B kit, removing the need for specialised data
connections or complex setup processes.
Connecting via Optimus Dynamic
Also supported is the Optimus Dynamic connection method which, when used with an public-IP enabled SIM
card with a public IP address, allows for communication directly between the Optimus and the NoiseTools
software.
If this connection method is to be used, please contact Cirrus Research for details of the type and specification
of SIM card required.
