People continue encountering 3GPP files because infrastructure-oriented formats tend to stay, and once early phones and telecom systems embraced 3GPP, countless recordings accumulated that never updated with new tech; telecom and enterprise systems prioritize reliability, so platforms built around 3GPP keep outputting it, meaning users run into the format now simply because it was never replaced.

Finally, legal, medical, and enterprise archives preserve original formats because re-encoding can compromise authenticity or chain-of-custody rules, so recordings are distributed exactly as created—including 3GPP containers—and modern software continues supporting them cheaply to maintain historical access; people encounter 3GPP today not because it is modern but because long-lived systems keep it, and infrastructure formats persist far longer than consumer ones, leaving huge amounts of early mobile and telecom recordings stored in backups and legacy hardware that resurface during migrations or audits.
Another key reason is that telecom and enterprise infrastructures avoid modernization if it risks reliability, so platforms such as voicemail, IVR, and call-recording systems built around 3GPP keep using it because altering formats is costly and risky, which is why 3GPP still appears; additionally, surveillance and embedded systems rely on low-power encoders ideal for 3GPP, making exported footage naturally surface in this older format.
In addition, a variety of modern workflows rely on 3GPP as an internal or intermediate step, processing media in that container and switching to MP4 only when delivering the final output, meaning any raw access or incomplete export shows the 3GPP file and creates the illusion of obsolescence though it’s working properly; finally, regulated archives in legal, medical, and
enterprise contexts preserve originals to maintain authenticity, distributing 3GPP unchanged and relying on inexpensive ongoing support, which keeps the format present in long-lived infrastructure rather than modern usage.
