Does EastESIM work in the remote areas of Laos like Phongsali?

In extremely remote regions of Laos, such as the mountainous province of Phongsali or the northern reaches near the Chinese border, mobile tower infrastructure is still developing. While EastESIM partners with leading local carriers like Lao Telecom, coverage can be very limited or non-existent in deep rural areas. For safety and navigation, we recommend downloading offline maps and essential information before venturing into these less connected parts of Laos. Expect better coverage in towns like Luang Prabang or Vientiane.
