Given the exact make and model numbers of the phone are unknown,
and the same for its presumed origin, chain of custody, hw and sw loads
and rev numbers, etc... anything further would be just more speculation.

Till then, buy an identical phone and new sim from a different source,
and know baseband attack can probably dump new code into it at will.
