The conversation between human and AI assistant.
How does WhatsApp work, since if you change the SIM on your cell you will still get messages and notifications?
That's good to know. What about voice calls and video calls on WhatsApp? Can I use those if I change my SIM card?
Yes, you can still make voice and video calls on WhatsApp even if you change your SIM card. The app uses an internet connection, such as Wi-Fi or mobile data, to make calls, so your phone number doesn't matter in this case.
