The Secret Telstra Handshake

The NextG modem is sold without an airtime agreement. The user must arrange connection of the modem to a network and have it enabled for data use. The service provider will supply a Subscriber Identification Module (SIM), which plugs into the MM-6280IND and acts as a key to enable its use.

When setting up the account, the service provider may require some information such as the make and model of the modem being used. They will then set up an account and provide a phone number. This phone number is a voice number. However, voice is not supported in the MM- 6280IND, and it is not possible for the data logger to receive data calls (circuit switched data) and SMS with a voice number.

A data number is required for circuit switched data and SMS transmissions to the data logger. The service provider will need to know this information when setting up the account and enabling the SIM card. Furthermore, you will need to ensure that Code 2620 is activated on your account.

Code 2620 is Telstra’s code for data service on NextG. There are also options that can be specified to reduce complexity and cost of the service. You can strip all ancillary services such as Call Waiting, Call Diversion and Message Bank as these are not required.

If the unit is set up with a security code or pin number, it should be disabled before use with the Campbell Scientific data logger. The security code or pin number can be disabled by putting the SIM card into a normal digital mobile phone and select the security menu. Exact key presses will depend on the mobile phone used, but from this menu the PIN should be able to be disabled.
