Coverage in the Sapa region of Vietnam can vary. You'll find strong signal in Sapa town itself and in larger villages often visited by trekkers, such as Cat Cat or Ta Van. However, as you venture deeper into more remote H'mong or Dao ethnic minority villages nestled amongst the rice terraces, connectivity may become limited or disappear entirely. Our EastESIM leverages top local carriers like Viettel, but even they have their limits in truly isolated mountainous areas, so prepare for some digital detox during deep treks.
