📱 Dual SIM Profile in Vietnam: Complete Guide 2025
Travelers and expats often prefer using a dual SIM profile in Vietnam to balance between international roaming and local connectivity. Whether you use an iPhone 16, Samsung Galaxy S25, or Pixel 9/10, managing two numbers simultaneously can be convenient. This guide explains how to set up, switch, and optimize dual SIM profiles with real case studies and Vietnam-specific examples.
🔑 What is a Dual SIM Profile?
A dual SIM profile allows your smartphone to operate with two SIM cards (physical + eSIM, or eSIM + eSIM). In Vietnam, this is extremely useful:
- 👉 Keep your home country SIM active for banking SMS and OTPs.
- 👉 Use a Vietnam eSIM for 4G/5G data and cheap local calls.
- 👉 Switch between work and personal numbers seamlessly.
📊 Why Travelers Prefer Dual SIM in Vietnam
Based on 2024–2025 surveys by Vietnam’s Ministry of Information and Communications, more than 65% of foreign visitors prefer eSIM or dual SIM setups to avoid roaming fees. With 5G expansion in cities like Hanoi, Ho Chi Minh City, and Da Nang, having a local profile ensures faster speeds and stable coverage.
Linda from Taiwan visited Hanoi for 3 weeks. She used her Taiwan SIM for banking and installed a MobiFone 20-day eSIM (4GB/day). The dual setup saved her over $120 in roaming charges.
