uqmi will include in the --list-messages output SMS messages stored in
the UIM storage (e.g. the SIM card, QMI_WMS_STORAGE_TYPE_UIM) and also
only those flagged as not-read (i.e.g
QMI_WMS_MESSAGE_TAG_TYPE_MT_NOT_READ). If I'm not mistaken, here's
that selection:
http://git.openwrt.org/?p=project/uqmi.git;a=blob;f=commands-wms.c;h=700d79ff9636c3cdb06ef34d33c3f3ce21d226dc;hb=HEAD#l42

Could it be that the SMS messages you expect to see are in another
storage (e.g. in the device storage, QMI_WMS_STORAGE_TYPE_NV)?
Or, could it be that you don't have non-read SMS messages?
