Mobifone eSIM with Phone Number – A Complete Guide for Travelers
Choosing a Mobifone eSIM with phone number is one of the smartest ways to stay connected during your trip to Vietnam. Whether you’re a digital nomad, long-term traveler, or a short-term visitor, having a local number is essential for Grab rides, food delivery, bank OTPs, and more.
Why Travelers Need a Vietnam eSIM with Phone Number
Unlike data-only plans, eSIMs with phone numbers allow you to:
- Receive OTPs from Vietnamese banking apps
- Register for ride-hailing services like Grab or Be
- Make and receive local calls or SMS
- Use Zalo, MoMo, and other Vietnamese apps requiring phone verification
This makes the Mobifone eSIM with phone number a better option for those needing full functionality in Vietnam beyond just internet access.
What Is Mobifone and Why It Matters
Mobifone is one of Vietnam’s top three telecom providers, known for its stable coverage across urban and rural areas. Compared to Viettel (state-owned) and Vinaphone, Mobifone often provides smoother customer service and competitive prepaid packages.
For travelers, Mobifone’s eSIM solutions are particularly useful in major cities like Hanoi, Da Nang, Nha Trang, and Ho Chi Minh City, where 4G coverage is strong and VoLTE is supported.
Key Features of Mobifone eSIM with Phone Number
The Mobifone eSIM product offered through trusted platforms like GoVnSIM includes:

- Instant QR code delivery via email

This makes it perfect for those who need seamless setup and support without visiting a physical store.
How to Activate a Mobifone eSIM with Phone Number

Pro tip: Be sure your phone is unlocked and eSIM-compatible. Most newer iPhones, Google Pixel, and Samsung Galaxy models support eSIM functionality.
Comparison with Viettel eSIM
While both Mobifone and Viettel offer strong service, Mobifone eSIMs are often better suited for users who:

Common Issues and How to Solve Them
