WhatsApp will stop working on three phones within days, according to Mail Sport.
The app is one of the world's most popular for messaging and is used by over two billion people around the globe.
But from May 5, anyone still using three Apple devices will not be able to send or receive messages on the app.
Beyond this date, only devices running the iOS 15.1 operating system or newer will be supported.
The affected devices are the iPhone 5s, the iPhone 6, and the iPhone 6 Plus.
“Every year we look at which devices and software are the oldest and have the fewest users.
“These devices also might not have the latest security updates, or might lack the functionality required to run WhatsApp,” a WhatsApp spokesperson said.
The oldest of the affected phones, the iPhone 5s, was released over a decade ago in 2013 while the most recent, the iPhone 6 Plus, was released just a year later in 2014.
All of these iPhone models were discontinued by Apple in 2016 and were officially declared obsolete.
