I was able to add esim via lpa and succesfully added 3 global esim, but they support 4g only or 5g nsa. By default i received the module in 5g sa mode with band 78 enabled. So I want to know if i can get LTE working on this ? or is it not supported ? because i can add bands from

AT+QNWPREFCFG="lte_band"

but maybe i am doing something wrong.

Dear @BlueNecko
In standard firmware, it supports LTE bands.
But your firmware version is RG520FJOAAR05A03M4G_OCPU_LXA, I am not sure if your supplier had changed some configurations.
