Once you get oof your plane and start walking through the streets of Sri Lanka, you’ll want to purchase a local SIM card for your phone. Your choices in this regard are Dialog, Airtel, Mobitel or Hutch. Now, you can pick these up from a shop on the streets or at the airport itself.
With your local SIM card in hand, you’ll have access to international calls and mobile data. This means you’ll be able to use apps such as WhatsApp, Skype and Google Maps – all of which can be really useful when traversing through Sri Lanka.
