For your Geo SCADA Expert GSM network connection, we recommend that you open a machine-to-machine account - it is not necessary to open a voice & data account. You can help to ensure security by using a different PIN code from the default code given by the network operator (usually 0000). With some network operators, you will need to request that they activate the modem SIM card before Geo SCADA Expert uses it. You can do this by telephoning the network operator. The purpose of the activation is to:
- Enable you to be connected to the network
- Set up regular billing on your account.
The number of SMS messages that a SIM card can receive before it fails is limited to several tens of thousands. Therefore, we advise that you request a spare SIM card in advance from your network operator. You can activate this spare SIM card, and substitute it for the primary card, during periods of scheduled maintenance or in case the primary card fails. To help avoid loss of data, you must have a suitable maintenance schedule in place that takes into account the projected life of the modem SIM. You should also choose a network provider that will help you to change the SIM quickly in case of failure (that is, by transferring the telephone number to the new SIM). For more details see your network provider.
