There is actually some 3GPP spec that mandates low-functionality mode if FDN is not properly supported by the terminal. e.g. 31.102: "In case FDN is enabled, an ME which does not support FDN shall allow emergency calls but shall not allow MO-CS calls and MO-SMS. If BDN is enabled, an ME which does not support Call Control shall allow emergency calls but shall not allow MO-CS calls." > > If we don't support FDN restrictions, we don't support.
