8. SIM CARD It is advisable to purchase your SIM card from your chosen GSM network service provider’s agent.
When purchasing it is indispensable to:
– ask for a card enabled for the transmission and reception of data and fax.
Usually, the network operator will supply a SIM card with three telephone numbers:
- a VOICE number to be used for voice TELEPHONE calls.
- a FAX number to be used for fax communications.
- a DATA number to be used for telemanagement.
– ask for the following modes for communication data:
- Asynchronous – “TRANSPARENT” (error correction disabled)
- Asynchronous – “NON TRANSPARENT” (error correction enabled)
Before installing the SIM card in the modem it is essential to disable the PIN code on the card.
This can be done by inserting the SIM CARD in a cellular telephone and altering the security settings of the SIM
using the phone menu system.
