Coverage in very remote areas can be a bit patchy, as with any network. While SouthESIM offers strong connectivity in towns and along main routes near places like the Amazon Rainforest, deep jungle excursions or very rural areas of Laos might have limited to no signal. Our practical tip: download offline maps and any important information before heading into these truly off-grid spots. You'll generally have signal in nearby towns like Iquitos, Peru, or Luang Prabang, Laos.
