Good to know
Good to Know
- Multiple SIM cards are essential: Arugam Bay requires having at least two SIM cards (Hutch as primary, Mobitel as backup) because single-carrier coverage is unreliable.
- WiFi in accommodation is unreliable: Most hotels and cafes use old wiring or cheap throttled 4G connections; do not depend on venue WiFi for critical work.
- Dialog is not recommended for Arugam Bay despite being popular nationwide: It has poor coverage and speeds in this eastern coastal location.
- Network stability issues during rain: Sri Lanka's internet is prone to outages during heavy rainfall, with weather patterns becoming less predictable.
- Coworking options exist but are limited: Siam View Internet Cafe (open 24/7) offers the most reliable dedicated workspace; commercial cafes typically cap WiFi use to 1–2 hours.
- e-SIM is convenient for short stays: Tourist e-SIMs (Airalo, Holafly, Saily) start under $7 USD and avoid SIM registration paperwork, making them ideal for visits under 4 weeks.
