Will I have internet coverage in the interior (e.g., at Kaieteur Falls or in the rainforest)?

It is very limited. You must set your expectations correctly. You will have good 4G/LTE coverage along the coast, especially in Georgetown, Linden, and New Amsterdam. However, 90% of Guyana is remote rainforest. Once you fly or drive into the interior (e.g., to visit Kaieteur Falls or jungle lodges like Iwokrama), you should expect little to no mobile signal. Our eSIM connects to the best available towers, but it is not a satellite phone. Download all maps offline.
