Inserting a SIM Card

To insert a SIM card:

1. Ensure that your SIM card is unlocked.

   

   Note

   In some cases, you may need to identify the unit IMEI (International Mobile Equipment Identity). To access this information, please refer to Getting IMEI, IMSI, and ICCID Numbers.

2. Insert the SIM card into a slot in the unit's rear panel.

   • Modem 1 uses slot 1A and slot 1B.
   • Modem 2 uses slot 2A and slot 2B.
   

   Note

   We recommend using SIM cards from multiple mobile operators and distributing them evenly (avoid loading the product with SIM cards from the same mobile operator everywhere). It does not matter in which order you assign SIM cards to slots in the transmitter. You may choose to adopt a pattern of your own design to have consistent assignments across all your devices, but this will have no impact on the operation of the transmitters.
