🇻🇳 About eSIMs in Vietnam
Vietnam is deceptively well-connected. Viettel — the country's largest carrier — reaches almost every corner of the country including the Ha Giang loop and the Mekong Delta villages. Wanderly Vietnam eSIM plans use Viettel or Vinaphone, so you get 4G in Hanoi, Ho Chi Minh, Da Nang, Hoi An, and along the Reunification Express train route from north to south.
Travelers here lean hard on Grab (taxis, food, even groceries) and Google Translate for menus, so plan for 8–12 GB per week if you are moving between cities. Motorbike tours through Ha Giang and the coastline south of Da Nang have surprisingly good signal — you can share your live location with family without effort.
Airport SIM kiosks at SGN and HAN are heavily marked up. Install the Wanderly eSIM at home and you land connected, no cash exchange or paperwork required.
