Service procedures

Dual Bootstrap eSIM Operator Swap

Swaps the Embedded Subscriber Identity Module (eSIM) operator from AT&T to KPN and vice-versa. For the procedure to execute properly, the 'kpn' input must be set to 'true' to switch to KPN and 'false' to switch to AT&T. Before running this procedure, check vehicle vitals to confirm the modem is reporting back to the car computer. If modem processes were recently restarted, the modem can take some time to respond.
