Sri Lanka's telecommunications has been growing rapidly in recent years.
Which, while appreciated by travelers, it is essential to the Sri Lankans themselves.
You have four mobile operators in Sri Lanka: Dialog Sri Lanka, SLMobitel (formerly Mobitel Sri Lanka), Hutch Sri Lanka & Airtel Sri Lanka.
There are no Mobile Virtual Network Operators (MVNOs) in Sri Lanka, so you only have the four options from above.
Anyway, I tried and reviewed the Sri Lankan SIM cards back in 2020.
The thing is… I wrote those reviews a few months after starting Phone Travel Wiz.
And they are bad 💀.
Currently, I am in Australia (writing this in June 2022) and will stay here until at least April 2023.
I will not be visiting Sri Lanka anytime soon – probably not before 2024.
So it will take a whole before I will test the SIM cards again.
Luckily, things will be even much better by then, so it is a blessing is disguise.

Worry not; the updated reviews will be much better once I get to them 😉.
