Owners of some phones will discover that they won’t be able to use WhatsApp from January 1.
The devices which run the Series 40 operating system will no longer be supported in 2019, The Mirror reports.
Perhaps worrying is that some of the phones that ran the S40 OS were enormously expensive.
The Vertu Signature S, for example, was around £8000 (Ksh1 million) at launch and now won’t be able to run WhatsApp.
However that phone is over 10 years old now and most people who had the money to buy one would probably replace it every few months anyway.
However more mainstream devices like the Nokia 6300 are also affected.
This change is likely to have a considerable impact on some people, especially older users who keep a phone for talking to family but who aren’t big smartphone users.
Phones that already had installed and verified their account could carry on accessing the service until yesterday but will no longer connect from today.
WhatsApp says the following phones will be affected;
Nokia 206 Single SIM and dual SIM models
Nokia 208
Nokia 301 Single SIM and dual SIM Chat Edition
