Kandui Resort's internet is as good as you can get in the Mentawai Islands. It is definitely not as fast as you get at home, can be inconsistent at times, and frustrating but it's the fastest conenction we've seen in Indonesia. The internet is currently 100% FREE so you can have the option of staying in touch with your family, friends, and the office. We encourage most people to use their personal laptops in their uma, the restaurant, or the gameroom if you'd like to get online. If you don't want to bring along a laptop there are a few computers at the resort available to check surf reports, send e-mails, and make phone calls.
As long as you have signed up for an International Data, Calling, and Text plan your smartphone should be able to get a limited signal on the island from time to time. Tablets can also connect to our WiFi connection easily but for all of our guests we can't emphasize enough that the internet is best served doing the most basic tasks only.
