Best SIM and eSIM for Sri Lanka: data plans, Wi‑Fi and phone tips

If your phone supports eSIM, get a Dialog eSIM at Bandaranaike International Airport – it offers the widest 4G coverage, easy activation via QR code, and a 5 GB package for about LKR 1,500. Use it for the whole trip; only buy a physical SIM if you need a second line or your device lacks eSIM.

At the airport you’ll find counters for Dialog, Mobitel (SLT‑Mobitel) and Hutch. Bring your passport; the staff will register the SIM. For an eSIM, ask for a Dialog QR code, scan it with your phone’s settings, and choose a prepaid data bundle. Activation is instant.

Common prepaid bundles (2026 estimate):

• 1 GB – LKR 500 (≈ US$1.30)

• 5 GB – LKR 1,500 (≈ US$4)

• 10 GB – LKR 2,800 (≈ US$7.50)

All include unlimited local calls and SMS. Prices are subject to change; check the provider’s website before purchase.

Most recent iPhone (XS and later) and Android (Pixel 4, Samsung Galaxy S10 and newer) support eSIM. If your phone lacks eSIM, a physical SIM from Dialog, Mobitel or Hutch works the same way. Ensure your device is unlocked before arrival.

Wi‑Fi is widely available in hotels, guesthouses and cafés, especially in Colombo, Kandy and the south coast. Speeds are generally good in towns, slower in remote villages. Power cuts have become rarer since the 2022 crisis, but carry a portable charger for long bus rides.
