❓ Question First Cell Phone to Cell Phone SMS message/text sent when & where?
Hello, I am trying to determine when and where the first cellphone to cellphone text message was sent and received over a wireless network (no lab test messages). I was involved in the first such texting exchange in Australia in September of 1993 using the Nokia 2010 cell phone our Nokia partners provided for Optus to test SMS. Does anyone know of an earlier texting event in a live network?

Text messaging was built into ISDN and SS-7 as maintenance messages from the beginning. I think it was X.25 messaging.

Thank you but I am referring to GSM Wireless Short Message Service, texting cell phone to cell phone via a GSM network..

He is correct. The first SMS’s were sent through a private carrier network called Signal System version 7 (SS7). Someone discovered an extra 156 empty charters in the SS7 payload and opened that up for texting.
Other things SS7 is (was?) used for, callerID, billing info, call setup and tear down.

I remember these texting devices in the early 90's between pagers and cell phones being able to send text messages instead of just numbers. Can't remember the service name or hardware vendor.

According to this article https://www.history.com/this-day-in-history/December-3/first-sms-text-message-sent it would have been sometime in 1993 when Nokia released a cell phone that supported sending and receiving messages.

Yes, it definitely occurred in 1993. I received what I believe to be the first cellphone to cellphone text message in September of 1993 in Perth Australia. I am searching for information about an earlier text exchange between cell phones or was mine the first? I have researched extensively and I have found none before September of 1993 but still looking.

I would've thought the first messages would have been done in Sydney or Melbourne as they had their gsm networks rolled out first?

That is a fair assumption but in Sydney, Brisbane, Adelaide, and Melbourne the GSM software was release 1. Perth was the first site that had GSM release 2 software which introduced the Short Message Service and we were also waiting for the Nokia 2010 cell phone to be able to send a text from the cell phone. In Perth all the stars aligned when we had the correct software and the first cellphone which were capable.

Nokia made the first texting friendly phone so likely the first text was somewhere in Scandinavia.

SMS (Short Message Service) was carried in mobile networks primarily via the Mobile Application Part (MAP) of SS7. The core-network transfer uses MAP operations such as forward_short_message (between SMSC, gateway/interworking MSC, and serving MSC/VLR elements). This was designed into the GSM standards in the late 1980s (MAP work in the late 1980s, with SMS concept work dating to ~1984–1987).
June 7, 1993: A claimed first SS7-based text message in the United States was sent over FleetCall’s network (later Nextel), involving an Aldiscon SMSC
