How hard is it to cancel Viettel?

Viettel scores 52/100 (grade D) for how clearly it documents cancellation in the VN — a poorly documented cancellation policy. Cancellation is available via in-app, phone, in person, email.

Last reviewed 2026-06-06 · Documented-Policy tier · grade D

Mobile package cancellation is available via SMS to 191 (send HUY [package-name] then confirm with Y), through the My Viettel app, or by calling hotline 198 — cancellation stops auto-renewal at end of cycle, or HUYDATA cancels immediately with forfeiture of remaining benefits. Fiber/broadband internet cancellation requires at least 15 days advance notice and must be done by calling 18008119 or visiting a Viettel transaction office in person with ID; the My Viettel app does not support internet contract cancellation. Viettel does not issue refunds or prorate unused days upon cancellation — the charge already made is final and non-refundable. Customers must settle all outstanding fees and return any borrowed equipment before the internet contract termination is processed.

Evidence

Scope & fairness

This is the Documented-Policy tier: it measures how clearly the cancellation policy is published (cited, dated facts), not the behavioural experience of cancelling (Verified-Flow audit pending). Every company is scored on the same five dimensions with the same published weights — scores cannot be bought or removed. It is opinion grounded in disclosed facts, and not legal advice.
