Buying a SIM card at Golden Bay Mall vs. the airport: which is cheaper?

DAD Airport has Viettel/Mobifone/Vinaphone counters right upon arrival — convenient but 20-30% more expensive than buying in the city. If you already have Grab active, you can buy it in the city later. Golden Bay Mall (Tran Hung Dao street, Son Tra) is the cheapest place — there are many competing dealers.

Popular packages in Golden Bay: Viettel V90 60-70k/month (30GB, instead of 90k at the airport). Mobifone MobiF 150k/month unlimited (instead of 200k). eSIM and physical SIM available. Main store: Thế Giới Di Động Golden Bay, 1st floor, MobileWorld Sơn Trà.

For travelers staying < 7 days: Viettel D30 package at 30k/day with 5GB — no need to buy a full month. For stays of 2-4 weeks: the V90 monthly package is perfect. If using iPhone XR+: choose eSIM (activate via QR, no physical SIM needed). Avoid travel SIM agents offering special prices of 500k/week — most are actually monthly plans with inflated prices.
