Wi-Fi is widely available at guesthouses, hotels, and many restaurants in Tuk Tuk. Quality varies. Mobile data from local SIM cards offers reliable 4G/LTE coverage in and around Tuk Tuk and along main Samosir Island roads.
Postal services exist in larger towns like Pangururan, but tourists do not commonly use them. Most communication is digital. If sending postcards, ask your guesthouse for the nearest post office location.
Bahasa Indonesia serves as the national language. Batak Toba (and other Batak dialects) is spoken by local communities. Many working in tourism in Tuk Tuk speak English. Outside Tuk Tuk, in smaller villages, English proficiency diminishes.

While Lake Toba is mostly Christian, many visitors and transport staff are Muslim. Holidays can impact service availability.

Shake hands lightly with both men and women upon introduction. Use appropriate verbal greetings.
