VoyaSIM's Vietnam eSIM connects to Viettel, Vinaphone, or Mobifone (varies by plan), with 4G/LTE nationwide; 5G in Ho Chi Minh City, Hanoi, and Da Nang. Coverage spans Ho Chi Minh City, Hanoi, Da Nang, Hoi An, Ha Long Bay, Phu Quoc, Nha Trang, and Sapa.
Good to know: Coverage is excellent even in mountainous Sapa and Ha Giang regions thanks to Viettel's infrastructure investment. Overnight trains and Ha Long Bay junk cruises usually maintain signal near coastal/track areas.
