Yes. WhatsApp works perfectly in India when you’re connected to the internet using an India eSIM, local SIM card or WiFi. You can continue sending messages, making voice and video calls, sharing photos and using all of WhatsApp’s features just as you do at home.
One of the biggest concerns travelers have before buying an eSIM is whether they’ll lose their WhatsApp number. The good news is that installing an India eSIM does not change your WhatsApp account.
Quick answer: your India eSIM only provides mobile data. WhatsApp continues using your existing phone number, contacts and chat history.
Top India eSIMs
Will My WhatsApp Number Change?
No.
Your WhatsApp account remains linked to the phone number that you originally registered with.
Installing an India eSIM simply gives your phone an internet connection. It does not automatically change your WhatsApp account or your registered number.

WhatsApp voice and video calls work normally over your India eSIM internet connection.
