SIM cards under 300,000 VND? Viettel Store in T2 has them.
Viettel Store sits in Tan Son Nhat’s international Terminal T2, and it’s the straightforward stop for getting a local SIM right after landing. You’re dealing with one of Vietnam’s biggest telecom providers, so coverage around Ho Chi Minh City and along the main tourist routes (Hanoi, Da Nang, Hoi An) is solid. Expect tourist SIM packages with data and some domestic minutes, usually starting under 300,000 VND for around 7–10 days of use.
The shop focuses on mobile services: prepaid SIMs, top-up cards, and occasionally basic accessories like chargers and cables in the 100,000–300,000 VND range. Staff typically activate the SIM on the spot, so allow 10–15 minutes before you walk to immigration or your T2 gate. Bring your passport; Vietnam requires registration for SIM cards and they usually photograph the ID page at the counter.
Most short-stay visitors go for data-heavy plans in the 5–15 GB range, which easily covers a week of maps, Grab, and messaging. If you already have an eSIM-capable phone, ask clearly for “eSIM” at Viettel Store in T2; availability varies by day, and if they say no, you’ll be using a physical nano-SIM instead. Payment normally works with cash in VND and sometimes international credit cards, so have a backup method ready.
Final tip: take a quick photo of the SIM package and the Viettel customer service number before you leave the counter; it saves time later if you need a top-up or lose the paper.
