With delivery reports activated on my mobile phone with AIS as provider, does the recipient have to open the SMS before the delivery report says it has been delivered?

Or does the report come back to me when the recipients mobile has received the SMS?

SMS sent to AIS also here in Thailand.

Thanks

Delivery report comes as soon as the adressed phone has received the message.
