Because pretty much everyone who isn’t from the US is on WhatsApp, and voip calls quality is infinitely better than normal voice calls.

I either use FaceTime or WhatsApp.

The majority of times when somebody calls me over WhatsApp, I can't properly hear them and need to hang up and switch to a regular call, which works properly

[fooblaster]

I do the opposite

You or them have some issue with device, whatsapp calls work perfectly fine for past 15 years. If needed you can quickly switch to video, good luck with normal calls.

Back home 5g signal is weak, so my phone does even regular calls over wifi/network, then you are 1:1 with whatsapp or similar apps. No more missed or interrupted calls due to blip in coverage.

Here in Europe I know exactly 0 people who don't have it, even online contact forms of various webs and companies have direct whatsapp contact.

East Asia isn't on Whatsapp. In most of South-East Asia it's also not the #1. That makes for ~2 billion people.

[malthaus]

but most phone numbers you are clicking on a web page (the cited use case) won't have a whatsapp account behind it

[nathancahill]

No, overseas most do and it's endless frustrating right now:

1. Long press on the phone number, but don't tap it otherwise it calls

2. Choose Copy phone number

3. Create a contact

4. Refresh WhatsApp by quitting and reopening

5. Find the contact on WhatsApp and call

If you're calling multiple companies for bookings or quotes, repeat this over and over.

Are you sure about that?

Could imagine that countries like India the majority of buisneses also have an whatsapp account.

Never tried it, but it seems that calling a regular non-account via whatsapp will still work. But routed through watsapp servers. If someone can confirm or deny that, would be cool.

[dubcanada]

That's hugely incorrect, most of Asian, Europe have whatsapp numbers listed, not phone numbers.
