This is on display at 1010, one of Hong Kong’s top phone service providers.
My 64 and 65 year old parents cited this specific service as a big reason for choosing to purchase a phone from 1010.
They use Whatsapp to stay in touch with their friends, also in their 60s, as well as the rest of our family, ranging from 20 to 50 year olds.
My mother even uses it with her vegetable seller at the wet market (at his request!) to chat about what’s fresh today, how much she wants to order, when is a good time to come by, etc. It’s pretty amazing.
