For the correct operation of the equipment the Micro SIM card must meet the following requirements:
A subscription to GSM and GPRS/3G/4G services
It must be cleared to be installed in any equipment (some SIM cards can only be installed in the equipment where they were purchased).
Verify the telephone number assigned to the SIM Card.
You must know the data to access the GPRS/3G/4G network of the telephone operator corresponding to the SIM card (APN, user, password). These data are preloaded in the GRD for Movistar Argentina, Telecom Personal Argentina and Claro Argentina. If you use another operator please contact support@exemys.com.
If the PIN (security code) of the SIM Card is activated you must enter it into the GRD when requested.
Place the SIM inside the GRD as shown in the figure or press it to remove
|
Do not insert o remove the SIM card while the GRD is powered on |
