Last updated: July 2025. This is a complete, updated guide from CafeTuoi18 based on real-world tests, user feedback, and insider VPN reports.
In early 2023, Telegram began facing intermittent service issues in Vietnam, with certain ISPs like Viettel and Mobifone silently throttling or blocking access.
By 2024–2025, those blocks became more widespread and targeted, particularly during:
Political events
National holidays
Periods of civil unrest or protests
From a legal perspective, Telegram isn’t officially banned. Instead, access is filtered — a quiet but powerful form of censorship.
🧠 CafeTuoi18 Insight:
“The Vietnamese government doesn’t block Telegram globally — only under specific ISP routing conditions. That's why a VPN bypass works perfectly.”
Let’s break down the user profiles that are regularly affected by Telegram blocks in Vietnam:
Often can’t access tour guides, expat groups, or family contacts
Telegram voice/video calls don’t work on mobile data
Miss important team chats and work groups
Use Telegram bots or channels for real-time business operations
Run online communities, client comms, automation systems via Telegram
Relocate often, so VPN is a must-have tech skill
Many crypto discussions and DAOs run on Telegram
Telegram’s privacy features attract blockchain communities
🔎 Case Study:
Ben, a British marketer based in Ho Chi Minh City, couldn’t receive client updates via Telegram until he activated ExpressVPN. Afterward, message delays vanished.
“Connecting…” spinner forever
Failed media uploads
Messages not sent/received
“This site can’t be reached” error on Telegram Web
Voice and video calls auto-fail
Most common on mobile networks (Viettel, Mobifone, Vinaphone)
Public Wi-Fi in malls, cafes, airports
Cheaper hotels and homestays using basic ISP packages
Vietnam’s internet law is strict, but VPNs themselves are not illegal. Many companies, banks, and even news agencies use VPNs daily.
💬 CafeTuoi18 recommends:
“Stick with well-known VPNs. Don’t use shady free VPNs or random browser extensions. Those are often spyware in disguise.”
Best option for long-term access
Reliable, secure, works on all devices
