Confirming its someone sending you a MMS that you cannot recieve.  Someone sent me a phone business card today and called me immediately afterward.  Since the SMS Unable to display message appeared from a different number, I googled it to check it.

Read the thread people, It is TELSTRA, not a girflriend, or a call centre trying to sell you something. It is anybody that sent you an MMS that your phone cant read, even someone you dont know with the wrong number.  Would be smarter if their system sent the sender a message that it cannot be delivered.

Think Mobile Sim, TELSTRA Network, Melbourne.

Wow... so many people thinking their husbands or boyfriends are cheating. How about you stop being jealous wenches going through your hubby/bf phones or im pretty sure they will get sick of you and dump/cheat on your [***] anyway :) lol

The message I get on my phone from this number is "message cannot be displayed".
I am presuming it is spam.  They have been texting me daily for the past 3 months.  I have not replied to this message.

I have been receiving mobile phone calls and text messages from +61428255768. They are now becoming a nuisance and anything you can do do to stop these would be appreciated

same number 5 years later +61428255768.....

just received same msg and its from unknown number.....reads msg can not be displayed.  Guess its the same Valentines msg that everyone else on here has received.
Think its a msg u send to someone u care for but wish to remain a secret ???

I daily receive a call from the number +61490098581. And he asks my personal details in my native language(Tamil). I think someone who is well known to me tries to find something. Can anyone make a call like this from any means(device/skype/Google chat/Yahoo messaging).

How could one make such a strange call.

"Message cannot be displayed"

This is what you get on a Telstra service when someone tries to send you an MMS or VCard and your phone doesn't support it.
-The sender thinks the message went through ok, theres no notification it didn't.
-The Telstra (not sender) number and message is all the receiver will see, changing sim to a capable phone won't retrieve what was sent either. So no clue as to who was trying to send you something.
-So don't rely on MMS for anything unless you know for sure the recipient can get it. Use email or some alternative as mentioned above.

got the same message, tried ringing back but can't connect. wierd!!!!

"message cannot be displayed" had 3 calls now 22/08/14

message received on phone from 0428 255 768 - with the message "unable to display message".  when i try calling it back it is engaged.

This number 0428255768 is textin me but i cant call! Message says: message cannot be displayed? If someone knows who is please tell me?

I received a text from this number, but it said msg unable to be displayed. So I put the sim card in my other phone.  Apparently its from ECHO probably a sales company.

Recieved two messgaes- i returned call. No answer- rang Telstra, it is not  number linked to Telstra.
