Frequently Asked Questions: Vietnam eSIM vs Physical SIM
Which option offers better value for money?
For most tourists and digital nomads, Vietnam eSIM offers better value—no tourist markups, flexible plan lengths, and instant activation. Physical SIM cards may come with bonus call/SMS credit, but prices are often higher at airports or tourist areas.
Is it easier to buy eSIM or physical SIM in Vietnam?
eSIM is much easier if your device supports it: purchase online, activate in minutes, no shop visit or paperwork. Physical SIMs require a visit to a kiosk, passport registration, and sometimes waiting in line.
Can I keep my home number active while using Vietnam eSIM?
Yes, that’s one of the biggest eSIM benefits! You can keep your home SIM for calls/SMS/banking and use eSIM for local data.
Can I top up or extend my eSIM plan in Vietnam?
Absolutely. GoVnSIM and leading providers allow easy top-up or renewal directly from their website—no need for a new QR code.
Do both SIM types work with all Vietnamese networks?
Most eSIMs and physical SIMs use Viettel or Mobifone, offering nationwide 4G/5G. Just confirm your plan/provider’s network for best results.
Is there a difference in internet speed?
Both offer top speeds on Vietnam’s main networks. Data-only eSIM plans and physical SIMs have the same LTE/5G performance; actual speed depends more on your device, plan, and network coverage.
What about using eSIM/physical SIM for banking and OTP?
If you need a Vietnamese number for banking, registration, or OTP, physical SIM is easier for long-term residents. Some eSIM plans now offer local numbers as add-ons (see Vietnam eSIM with Phone Number).
Case Study: Vietnam eSIM vs Physical SIM—A Traveler’s Experience
Case: Jack, a US traveler, arrived in Ho Chi Minh City for a 10-day adventure. He compared buying a physical SIM at the airport (40-minute wait, $15, passport needed) with ordering a GoVnSIM eSIM online (activated at his hotel in 5 minutes, $10, no paperwork).
Result: Jack enjoyed instant internet, used his US SIM for banking OTPs, and never had to worry about losing his SIM card or dealing with confusing shop options. For his second trip as an expat, he used a physical SIM to get a Vietnamese number for longer-term services.
