My BlackBerry 10 on O2 doesn't support SMS delivery report. So, I always put *0# code in front of my message. The tick changes to blue "D" as the message got to the receiver's network, but it doesn't change to "R" which the receiver opened/read the message. Does anyone know how to do to see "R".
@jonsie@MI5@aldaweb Thanks for your corporations! I understood that the sender can receive the delivery confirmation even if the receiver blocks the number. Many thanks!!
It is delivered into a hidden inbox on the phone. The phone just doesn't beep and let the owner know. The owner can check this folder should they wish to. So, you might still get the "D"
