I. Should I Buy a SIM Card at Tan Son Nhat Airport (SGN)?

If you need internet access right after landing in Ho Chi Minh City, buying a SIM card at Tan Son Nhat Airport (SGN) is an option: 

Availability & Selection

Tan Son Nhat Airport has several shops and kiosks selling SIM cards from major providers like Vinaphone, Viettel, and Mobifone. The selection includes prepaid voice & data plans, tourist SIM cards with bundled packages, and even eSIM activation. Prices are reasonable and comparable to shops elsewhere.

Convenient First Purchase

For short connections, buying airside means you can insert the SIM and have it working for immigration and onward travel. For long layovers it’s easy to go landside downtown with mobile data already activated.

Activation & Registration Requirements

Some SIM plans require activating and registering with your passport. This is easily done with staff assistance at SGN airport shops. However, SIMs bought downtown may require finding a mobile carrier shop for registration.

The airport SIMs are a convenient option in a pinch. But for better value and selection, moving around Ho Chi Minh City, you’re usually better off waiting until you settle into your accommodation to pickup a SIM.

Buying Online Before Departure and Airport Pickup

Several Vietnamese e-commerce platforms allow purchasing a SIM card online in advance, selected based on your usage needs. You then simply collect the SIM upon arrival at dedicated airport counters or convenience store locations. This avoids queues and shops at the airport. Providers offering this service include Viettel, Vinaphone, and Mobifone.

While convenient, one downside is you have less flexibility to choose a plan based on your needs once in Vietnam. You also cannot see the full selection of promotions that may be available in stores.

Specifically, the pre-ordered Vietnam SIM card will be available for pickup at the counter located in the airside area, which is past security checkpoints but before immigration processing. This airside area allows passengers to collect their SIM cards immediately after security clearance and before immigration procedures into Vietnam.

Good to know: Pick-up counter is 10 meters away from the entering zone of Immigration Counters - Next to Internal Landscape - Opposite the International Time Zone Clocks Area.

Buying at Airport Shops & Kiosks Upon Arrival

If you didn’t order online beforehand, there are plenty of clearly marked SIM card sellers after both domestic and international arrivals areas at SGN airport. Major mobile networks have stores located before and after immigration checkpoints (both landside and airside). Independent resellers also offer SIM cards with good rates.

While convenient due to immediate availability, purchasing a SIM upon arrival at the airport tends to be more costly. An better option is buying from city retail stores after transit to save money. However, airport purchase is suitable if internet access is urgently needed on arrival.
