Make sure we don't forward power _and_ supply SIM power at the same time
The FPF2005 has no reverse voltage blocker, this is why the 3.3V from
the LDO flows back into VCC_PHONE. It even damages the chip (so says the
datasheet) I corrected the double power source problem by disabling the
LDO (see patch), but still 1.8V does not work and 3.0-3.3V is used. I
have to look for other reasons.
