E: FX30 Factory Configuration

Some FX30 variants (such as FX30 Cat-1 WP7607-1) support eSIM. The external

2FF SIM slot is the preferred slot, but the internal eSIM will be used if no external SIM

is inserted. You can change the slot using the AT command AT!UIMS or the Legato

command cm sim select.

Note: If SIM AUTO SWITCH is enabled, the !UIMS setting is updated to reflect the preferred

slot. See

below.

The AUTO-SIM feature applies to Cat-1 and Cat-M variants, and is enabled by

default. This feature reboots the device and loads the carrier configuration (PRI) that

corresponds to the SIM. For example, if the external slot is enabled, and a Sierra SIM

is inserted, the Sierra carrier PRI will be loaded. By default, if a carrier PRI does not

exist (the SIM's carrier does not match a PRI loaded on the radio module), the generic

carrier PRI is loaded. Note that the AUTO-SIM feature is not persistent over a

firmware update; however, you can re-enable it by using the AT command

AT!IMPREF="AUTO-SIM".

SIM AUTO SWITCH

The SIM AUTO SWITCH feature applies to Cat-1 (R10.1.1 and later) and Cat-M (R11

and later) variants. This is a customization that allows a user to select the preferred

slot. By default, the external slot is the preferred slot. You can change the preferred

slot by executing the AT command AT!CUSTOM="UIMAUTOSWITCH".

Note: This command requires level 2 unlocking. See the

WP8548/WP75xx/WP76xx/WP77xx

AT Command Reference

for more information.
