Graba SIM Sri Lanka plans: data, validity and total price

The 20GB plan costs much more than the smaller sizes here. At about 0.7 GB a day, most week-long trips need around 5 GB.

Each plan is a one-off price for one eSIM. It starts when it first connects in Sri Lanka, and hotspot use comes out of the same data.

Using your phone in Sri Lanka

  • CMB Colombo Bandaranaike
  • HRI Mattala
Colombo and Negombo
Strong signal in both, including at the airport.
Kandy and the Cultural Triangle
Good in Kandy, Sigiriya and Dambulla towns; rural roads can be patchy.
The hill country train
The Kandy to Ella line passes through tunnels and tea country where signal comes and goes.
The south coast
Good in Galle, Mirissa and Unawatuna. National parks such as Yala have gaps.

Networks our Sri Lanka plans use: Hutch

  • A typical route moves every day or two. Save hotel addresses and train tickets offline, as the hill country has gaps.
  • Ride apps such as PickMe and Uber work in Colombo and Kandy and need data to book and track rides.

Going further with Three

  • Maldives (a beach week in the Maldives): Three charges Standard rates.
  • India (a combined trip to southern India): Three charges £8 a day (Go Roam Around the World Extra).
