Best SIM Cards and WiFi Options for Travelers in Sri Lanka
Staying connected while traveling is essential—whether it’s for navigating your route, booking accommodations, uploading photos, or staying in touch with family. Fortunately, Sri Lanka offers a variety of affordable and reliable mobile internet options for tourists. From budget-friendly prepaid SIM cards to hotel WiFi and portable hotspots, this guide covers everything you need to know about SIM cards and internet in Sri Lanka.
Why You Should Get a Local SIM Card in Sri Lanka

Whether you’re traveling for a few days or a few weeks, a Sri Lankan SIM card is the most convenient and cost-effective way to stay online.
