Which messenger is used in Sri Lanka?

In Sri Lanka, mainly WhatsApp is used, and other messengers are almost unknown. Only in very rare cases can you encounter Telegram and some other messengers. Therefore, before traveling to Sri Lanka, we advise installing WhatsApp in advance and registering with your home SIM card, so you can freely communicate with locals. To register for WhatsApp, you don't necessarily need to buy a local SIM card, and you can easily receive and send messages from your home number. For its operation, you can use hotel Wi-Fi or buy a local SIM card with internet. How to buy a SIM card in Sri Lanka is explained in the guide here - https://nashaplaneta.net/asia/srilanka/art-sviaz-internet-shri-lanka
