Yes, absolutely. Sri Lanka frequently experiences rolling power cuts, which instantly kills all Wi-Fi in hotels, guesthouses, and cafes. Mobile towers, however, have backup generators. An eSIM is your lifeline, providing a stable connection for Google Maps, WhatsApp, and booking transport when all other Wi-Fi is down.
Yes, to give you the best coverage, our eSIM connects to Sri Lanka’s premium Tier-1 network, Dialog Axiata. Dialog is widely known as the #1 provider with the fastest speeds and the most extensive coverage, especially in the central highlands (Ella, Nuwara Eliya) and rural areas where other networks fail.
Yes! This is the most popular reason to get a good eSIM. Our plan connects to Dialog Axiata, the best network in Sri Lanka. You will have a strong 4G signal for most of the 8-hour journey, especially when passing through towns. While it might briefly drop in deep valleys or tunnels, you will be able to post your photos and videos of the tea plantations in real-time.
Yes, in all key tourist areas. You will have strong 4G coverage for hiking Little Adam's Peak in Ella and in the town of Nuwara Eliya. For safaris, you will have a good signal at the entrances to Yala and Udawalawe National Parks and at the main lodges. The signal may drop when you are deep inside the park, but it's perfect for connecting as soon as your safari is finished.
Yes, 100%. The SIM card kiosks (like Dialog or Mobitel) at Colombo Airport are famous for their extremely long queues, especially after a big flight lands. It can take 30-60 minutes to get registered. Our eSIM is 100% digital, requires no ID registration or paperwork, and can be installed before you fly. You will be connected to the moment you land, ready to order an Uber.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
