SMS交付报告在冰淇淋三明治不出现 -- sms 领域 android 相关 的问题

After I send a message I used to get a delivery report confirming the delivery of a SMS message in my old (non-Android) phone.

But in my Intex Ibuddy Connect with Android 4.0.4 I am not getting the notification of delivery.

I have checked the option for the delivery report in the settings still, no change.

What could be the issue?

In android, (particularly in ICS), you don't get a pop up delivery notification as the ordinary phones. Instead there will be a tick in front of the date of your message. That's the maximum delivery notification you get.

If you really need some bigger notification, you can use an apps like Delivery Reports, Delivery Reporter+, Messaging Notification, etc.

Delivery reports are operator (sender and receiver) dependent feature. This will be successful only if both cooperates (usually happens). My operator BSNL is quite unreliable especially to the SMSs sent to international numbers. Several times it has happened for me - I would have not received a delivery report where as the receiver would have replied to my SMS!

I would suggest to follow these steps to ensure that the options are set correctly:

1. Make sure the delivery report option is ticked. In my LGP500 the user interface is quite confusing if you are in a hurry. Make sure the delivery report option is set for SMS and not for MMS - I fell for this quite a few times when ever I do factory reset.
2. Set the validity period to maximum.
3. Try sending a test SMS to a phone number of the same operator of yours and it will be helpful, if you can ensure the delivery yourself - like getting a reply from the receiver.

As @Sid said, the delivery reports are just seen as a small glyph like this: In my phone, I also get a toast message (a message saying delivered for few seconds). On long press on the message I had sent, I will have an option view report which will give the status as failure/pending/delivered.
