Use a mobile phone in Vietnam

Using a mobile phone in Vietnam has become increasingly straightforward as of 2025. Whether you are traveling, conducting business, or planning a longer stay, understanding the mobile system is beneficial. The three dominant mobile networks in the country are MobiFone, Vinaphone, and Viettel.

If you're a tourist visiting Vietnam for a short period, you can easily find a mobile store with a sign that reads “Bán SIM – Thẻ” (“Selling SIM card – Mobile card”). Here, you can purchase a prepaid SIM card activated upon purchase for approximately 70,000 VND – 90,000 VND. This card allows you to start using the mobile network immediately with a balance typically ranging from 100,000 to 200,000 VND. When your balance gets low, recharging is simple; just buy a prepaid mobile card worth between 20,000 VND and 500,000 VND to continue using the services.
