Why International Numbers Fail with Zalo in Vietnam
Many travelers try to use their home SIM or international roaming number to register Zalo, only to be blocked or miss the OTP code.

Pro Tips: Maximizing Zalo Experience as a Foreigner
- Always use a Vietnamese phone number for first-time Zalo registration or to recover your account.
- If you have an existing Zalo account tied to an international number, consider adding a Vietnam number as backup while you’re in the country.
- Double-check your eSIM includes SMS capability (not just data), as Zalo OTP is sent by SMS.

Troubleshooting: Common Zalo and eSIM Issues for Travelers
