Starting in October, these iPhone models will not work with WhatsApp
With more than 2 billion users, WhatsApp is the world's most popular chat platform
WhatsApp provides similar features to other similar apps.
WhatsApp's texts and calls are encrypted end-to-end, just like Apple's iMessage. It is also available on iPhone and Android devices.
WhatsApp continues to evolve, so older devices will lose access to the app soon. In October, WhatsApp for iPhone will require iOS 12, so some older iPhones will not work.
In early 2014, Facebook (now Meta) paid nearly $20 billion for the chat platform. Since then, WhatsApp has added new features over the years.
As a result, Facebook's platform grew in terms of monthly users but did not make money off of it.
Last year, Facebook
made a controversial privacy change to WhatsApp
, seeing plenty of pushback from users and some governments.
Despite millions of users flocking to competing products, WhatsApp remains the most used messaging app on iPhone and Android.
