No ATMs: There are still no ATMs on either Perhentian Kecil or Besar.
Cash is King: You will need cash for water taxis (RM10–RM50), local meals, and small snorkeling trips.
Cards: Premium resorts (like BuBu Resort) and major dive centers accept credit cards, but often add a 3% surcharge.
Digital Pay: Some local stalls now accept DuitNow (QR Pay), but this requires a local bank app and a stable signal. Always carry backup cash.
Best Networks: CelcomDigi has the most consistent 4G/5G coverage across Long Beach and the main resort areas of Besar. Maxis (Hotlink) is a close second.
Wi-Fi: Most resort Wi-Fi is satellite-based and struggles with heavy use. If you need to work, buy a local SIM card at the airport or Kuala Besut Jetty before boarding.
Power: Upscale resorts have 24-hour electricity. However, budget chalets often use generators and may turn off power between 10:00 AM and 5:00 PM.
Drinking Water: Tap water is not drinkable. To reduce plastic waste, bring a reusable bottle; many resorts provide filtered water refill stations for free or a small fee (RM1–RM2).
Clinic: There is one small government clinic at the Fisherman’s Village (Kecil). For emergencies, a boat transfer to the mainland hospital is required.
Jellyfish & Sea Creatures: Be wary of Triggerfish (they can be territorial) and occasional jellyfish. Most stings are minor, but vinegar is usually available at dive shops.
Travel Insurance: Ensure your policy covers “Water Sports” and “Emergency Evacuation.”
