Our pick for Sri Lanka, and when unlimited overtakes per-gigabyte
For budget travelers the pricing dimension is the one to read: HelloRoam publishes an entry rate of $3.50/GB and scores 4.8/5 there, ahead of Holafly at 4.7/5.

Holafly sells unlimited at $2.99/day, so a trip past 10 days costs more on the day rate than the 20GB rung costs outright at $28.03.
