Telegram OTP in Vietnam: How to Get a Local Number for Verification (2025 Guide)
When traveling or working in Vietnam, many people face issues with Telegram OTP. Without a local number, you may not be able to log into Telegram, verify your account, or secure two-factor authentication. This guide will explain how to receive Telegram OTP with a Vietnam number, comparing SIM and eSIM options, showing real 2025 market prices, and sharing practical traveler experiences.
💬 Why Telegram OTP Matters for Travelers
- Account Access: Logging in from a new country often requires OTP SMS.
- Security: OTP codes are part of Telegram’s two-step verification process.
- Work & Community: Many travelers use Telegram for group chats, work projects, or local expat communities. Without OTP, accounts can be locked.
📱 Can Foreign Numbers Receive OTP in Vietnam?
Yes, but not consistently. For example, if you keep your SIM from home country on roaming, OTP delivery may be delayed or blocked. Many travelers find that switching to a Vietnamese number (via SIM or eSIM) is the most reliable way to receive Telegram OTP instantly.

📊 Traveler Story: Telegram OTP in Da Nang (2025)
Maria, a freelancer from Spain, arrived in Da Nang for a one-month workation. She used her Spanish SIM on roaming but couldn’t receive OTP SMS when logging into Telegram on her laptop. Frustrated, she went to a city shop and bought a 15-day SIM with local number for about 400,000 VND (~16.5 USD). OTPs worked instantly, and she rejoined her work channels.
Later she found that a 30-day eSIM with number was available online for $18.50, delivered instantly by QR code. If she had known earlier, she could have saved the trip to the shop and avoided registration hassle.
Lesson: For remote workers, having a local Vietnam number makes Telegram login smooth and reliable. Ordering an eSIM before arrival saves time.

- SIM registration: Some shops require passport details; mistakes in setup may block SMS.
