1: Delivered to phone - sms has reached the destined phone and the reader MAY have read also. 2: Non-Delivered to Phone - SMSC was not able to deliver to phone for several reasons. validity expired; phone off; service was discontinued for that SIM.
4: Queued on SMSC - traffic was heavy on SMSC OR you set the deferred option. So, instead of immediate delivery, the sms is queued on phone. 8: Delivered to SMSC - not much clear on this. >16: Non-Delivered to SMSC - SMS didn't reach SMSC. may be n/w drop or some other problem. >Thanks to the shining soul that will answer me :-) I just tried :-)
