4G SIM / eSIM / wifi for foreign visitors: where to buy, which package?

Vietnam has 3 major carriers: Viettel (best coverage, works even outside the city), Mobifone (long-established network, stable in the city), Vinaphone (cheap, good data packages for short trips). All 3 carriers have 4G covering the whole of Da Nang.

Where to buy: The counter at DAD airport right when you land (cheaper than in the city due to competition). Or an official store in the city. Just show your passport, choose a package, and the SIM will be set up in 5 minutes. No need to register eKYC like in some other countries.

Popular plans: Viettel V90 at 90,000₫/month (30GB), Mobifone MobiF at 200,000₫/month (unlimited), Vinaphone D68 at 68,000₫/2GB per day × 30 days. eSIM: Available from Viettel and Mobifone, purchasable online via the app or website — activated with a QR code, no need to get a physical SIM card. Compatible with iPhone XR and later.
