Mobile network operators

Vietnam has three major mobile operators, all state-owned or state-controlled:

Viettel: largest operator, owned by the Ministry of Defence. Best 4G/5G coverage nationwide including remote areas ^[1].
VNPT (Vinaphone): second-largest, strong urban coverage, good broadband bundles ^[2].
MobiFone: owned by the Ministry of Information and Communications. Smaller share but competitive pricing ^[3].
Vietnamobile and Gtel (Itel, Reddi): smaller operators offering competitive data-only plans, popular for mobile data.

Tourist SIM (prepaid): available at airport arrivals. 7-30 days unlimited data for 50,000-200,000 VND (2-8 EUR). Passport required for registration.
Standard prepaid SIM: available at operator stores nationwide. Passport + valid visa required. Data packages from 70,000 VND/month for 4 GB; 200,000 VND/month for 30 GB.

eSIM: supported by Viettel and VNPT. Available for prepaid and postpaid. Online purchase possible for tourist SIMs.
SIM registration law: you must register all SIMs to an individual. The network blocks unregistered SIMs. Top-up requires identity verification if the SIM is newly registered (within the first 30 days).

Installation: 1-3 working days. Fibre-to-the-home (FTTH) is standard in all urban areas. Monthly payment via bank transfer or app.

4G/LTE: excellent in all cities and provincial towns. Rural coverage fair but improving.
5G: Viettel and VNPT offer 5G in major cities (Hanoi, HCMC, Da Nang). Coverage is limited to central districts as of 2026.
Speed test averages (2026): mobile download 30-60 Mbps, upload 10-20 Mbps. Fibre: 100-500 Mbps depending on the plan.
International bandwidth: Vietnam has multiple undersea cables (most notably AAG, APG, SJC2). Connectivity interruptions occur during cable maintenance (2-3 times per year, lasting days to weeks).
Starlink: available in Vietnam for a limited trial period as of 2026 (government-authorized pilot). Not yet generally available.

Prepaid mobile: 70,000-200,000 VND/month for 3-30 GB of data.

WiFi everywhere: cafes, restaurants, and hotels in cities have free WiFi. Speeds variable (2-50 Mbps).
Censorship / firewall: Vietnam operates a national firewall (the "Great Firewall of Vietnam"). Facebook, some news sites, and political content are occasionally blocked. YouTube works. Google Workspace is accessible. Use a VPN to access some home-country services and news sites.
SIM expiry: prepaid SIM credit expires if not topped up within 12 months. Keep a minimum balance to maintain the number.
Phone unlocking: Vietnamese phones are sold unlocked. Dual SIM is standard on most phones.
VPN: widely used among expats for accessing geo-blocked streaming and banking. Not illegal to use but regime restricts VPN providers that bypass the firewall. Consumer VPNs (Nord, Express, Surfshark) work.

Public WiFi: available at airports, shopping centres, and some bus/train stations. Registration required (SMS or app).
Cafe culture: WiFi is standard at all coffee shops. Quality varies but sufficient for messaging and email.
USB tethering: common practice among expats with generous mobile data plans.
