First-time visitors to Vietnam are recommended to buy a SIM card as soon as they arrive to guarantee internet access everywhere, as free WiFi might not be available in some public locations and remote regions.

 

Buy the SIM card at Vietnamese airports is the easiest way as the staff there can speak English and can guide you to activate your SIM card. 

 

You can buy a Vietnamese SIM card at Tan Son Nhat Airport in Ho Chi Minh City, Noi Bai Airport in Hanoi, Da Nang Airport, Cam Ranh Airport near Nha Trang and Phu Quoc Airport in the Mekong Delta.

 

 

Additionally, travelers can buy a SIM card by going to the official retail locations of mobile network providers. To find store addresses, go to their official websites.

 

These days, Viettel, Vinaphone, Mobifone, and Vietnamobile are the four major network providers in Vietnam that provide prepaid SIM cards.

 

With 42,000 broadcast stations and the largest 4G network in Vietnam, Viettel is recognized as the top mobile network provider by many seasoned foreigners.

 

 

 

The cost of a Vietnamese SIM card and prepaid data package typically ranges from VND150,000 to VND350,000 ($6.50-$15), based on your desired data usage and length of stay in Vietnam.
