I like travelling.Traveled to Colombo recently. Took a flight from Calicut Airport. While waiting to board the flight I show uniconnect sim counter casually just took the information about the srilanka sim and bought it.
We always get scared that the international sims are very expensive but to my surprise the sim cost was very low and there was no processing or activating fee. Now I am back with smile on my face that the sim worked really fine at times it was very handy as I had to coordinate with local driver.
