[Bug 1113703] Re: Trying to connect using a GSM modem without SIM card is not reported to user

[Thomas Hood]

** Changed in: gnome-shell (Ubuntu)
       Status: New => Invalid

** Description changed:

- Trying to connect using a GSM modem that lacks a SIM card does just give
- the user a general connection failure message without any hints about
- the missing SIM card.
- 
- This can fool the user into thinking something other is wrong than the
- fact that he forgot to insert the SIM card, or inserted it improperly.
+ When the user tries to connect using a GSM modem that lacks a SIM card,
+ NM just gives the user a general connection failure message; it does not
+ give any hint about the missing SIM card. This can fool the user into
+ thinking something other is wrong than the fact that he forgot to insert
+ the SIM card, or inserted it improperly.
  
  Latest modemmanager master branch gives in log:
  
  Feb  2 20:21:24 marius-T1005 ModemManager[1105]: <warn>  Modem couldn't
  be initialized: Couldn't check unlock status: SIM failure
  
  but there is no indication to the user (nm-applet behaves as if mobile
  broadband is unavailable).
  
  Seems I get (from "src/mm-error-helpers.c"):
  
      { MM_MOBILE_EQUIPMENT_ERROR_SIM_FAILURE,
  "simfailure",                                "SIM failure" },
  
  but should have got:
  
  { MM_MOBILE_EQUIPMENT_ERROR_SIM_NOT_INSERTED,
  "simnotinserted",                            "SIM not inserted" }
  
  Anyway (any of them should be enough hint to the user), it seems like
  the  error state is not propagated (src/mm-broadband-modem.c):
  
  static void
  iface_modem_initialize_ready (MMBroadbandModem *self,
                                GAsyncResult *result,
                                InitializeContext *ctx)
  {
      GError *error = NULL;
  
      /* If the modem interface fails to get initialized, we will move the modem
       * to a FAILED state. Note that in this case we still export the interface. */
      if (!mm_iface_modem_initialize_finish (MM_IFACE_MODEM (self), result, &error)) {
          /* Report the new FAILED state */
          mm_warn ("Modem couldn't be initialized: %s", error->message);
          g_error_free (error);
  
          mm_iface_modem_update_state (MM_IFACE_MODEM (self),
                                       MM_MODEM_STATE_FAILED,
                                       MM_MODEM_STATE_CHANGE_REASON_UNKNOWN);
  
          /* Jump to the firmware step. We allow firmware switching even in failed
           * state */
          ctx->step = INITIALIZE_STEP_IFACE_FIRMWARE;
          initialize_step (ctx);
          return;
      }
  
  Network Manager logs:
