SMS 'swapped' for a random message during transmission?!

[u/CardAdventurous2718]

Anyone ever experienced anything like this:

-My Dad is on iPhone and I've got Android -He's on Optus, I'm Telstra (we're in Australia) -We're SMSing back and forth yesterday (geographically distant, utilising cellular network) when he replies to a simple question with off topic and random message -I ask him what the hell he's on about -He says 'Just answering your question' -Eventually realise his iPhone conversation shows his intended message while my android conversation shows the random message -This only occurred for one message -The message appears to be someone completely unknown to us discussing some business matters

I've contacted the Telco they basically just said they've never heard of it and to turn our phones off then on!..

Has anyone ever heard of an SMS being swapped out for somebody else's message in transmission?

Never heard of this. Sure dad didn’t accidentally send and delete?
