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).
