🧠 How to Choose the Best eSIM for Your Vietnam Trip
Not all eSIM users have the same needs. Let’s break it down by travel style:
👨👩👧👦 Family Travelers
If you’re traveling with kids or elderly parents, you need stable connections, even in rural areas. Viettel eSIM is the best match here due to its excellent countryside coverage.
🎒 Solo Backpackers
Backpackers exploring Sapa, Ha Giang, or the Mekong Delta should prioritize eSIMs with strong regional signal. Viettel again takes the lead.
👔 Digital Nomads & Expats
Staying in Vietnam for 15–30+ days? You’ll need an eSIM with a local number and easy top-up. MobiFone is ideal for urban living and app verification (banking, Grab, Zalo).
📷 Short-Term Tourists
Coming for a 7-day tour or honeymoon? A data-only plan can save money if you don’t need calls or OTPs.
