⟩ Why is it that SMS/MO receives a sent and delivered acknowledgement but MT is not receiving the message?
MT stands for mobile terminated, which means the message
originated from mobileStorm and was ultimately sent
(terminated) at the end users cell phone. MO stands for
mobile originated, which means the end user created the
message or replied to a message via their cell phone.
Mobile-Terminated SMS (Short Message Service)
The capability for a mobile phone to receive short text
messages.
MT-SMS is usually accompanied by MO-SMS, which is the
ability to send and reply to such messages.
