Oh you can easily delete WhatsApp then. Can just SMS or Facetime her.

My mom isn't rich so hasn't got an apple device.

Neither have I, after 15y of OSX I didn't make the jump to the luxury brand.

I have an SMS limit, because after paying 20k of carrier fees over the years I now have the cheapest prepaid setup that is possible.

Make her switch, please!

No chance all grand children use whatsapp.
