+Subject: [PATCH] wwan: do not insist SIM ID being present
+
+It is perfectly possible for mm_sim_dup_identifier() to return NULL if
+the SIM ID wasn't provided by the modem for any reason, leading to an
+assertion failure:
+
+  (gnome-control-center:910641): cc-wwan-data-CRITICAL **: 12:43:51.573:
+    cc_wwan_data_set_default_apn: assertion 'self->sim_id != NULL' failed
+
+Handle the NULL SIM ID gracefully.
