One should not just perform a Test Primary when attempting COMMS troubleshoot (Which will only check if the current SIM is functional and can connect to AR Maintenance service via the primary method), but rather make use of Test SIM 1 (SIM Slot 1) and Test SIM 2 (SIM Slot 2) functionality in the new Maintenance Menu (Which will check both SIM functionality as well as hardware (SIM Slot 1 & 2) and if both SIM cards can connect to AR Maintenance services via the primary method).

This method will allow the terminal to log onto a specific network without opening the back cover of the terminal and manually swapping SIM cards around. The terminal will then automatically do a ‘SIM Swop’ upon attempting a transaction when a network issue occurs.

Notice upon attempting to a Test SIM 1 or Test SIM 2 the terminal will start counting in seconds (from 1 to 80 sec) before fallback to the previous SIM Slot occurs whenever the terminal can’t attached to the GPRS network.
