One of the most common questions we hear from nomads considering Vietnam: βIs the internet actually good enough to work?β The short answer is yes - Vietnam has invested heavily in broadband infrastructure and the speeds in major cities are competitive with Western Europe. This guide covers SIM cards, coworking speeds, home fiber options, and how to handle the rare connectivity gaps.
Vietnamβs Internet Infrastructure
Vietnamβs fixed broadband market is dominated by four providers: Viettel, VNPT, FPT Telecom, and CMC. All four run fiber-optic infrastructure into residential buildings and business premises across major cities. The country has invested significantly in international submarine cable connections (AAE-1, SMW3, AAG, and others), which means latency to European and US endpoints is generally manageable for video calls.
Typical coworking space speeds in Ho Chi Minh City, Hanoi, and Da Nang: 50 to 500 Mbps down, 30 to 200 Mbps up on a shared office connection. Premium spaces like Dreamplex (HCMC) and Enouvo Space (Da Nang) maintain dedicated fiber and advertise up to 1 Gbps. Real-world numbers on a shared connection during business hours are typically 80 to 200 Mbps download, which is more than adequate for 4K video conferencing, large file transfers, and cloud-based work.
Latency to Singapore (the regional internet hub): typically 15 to 30 ms. To Europe: 150 to 200 ms. To the US West Coast: 170 to 220 ms. These figures make real-time collaboration tools (Zoom, Google Meet, Slack) entirely practical.
SIM Cards: Which Provider to Choose
For mobile data, three providers dominate: Viettel, Vinaphone (VNPT), and Mobifone. All three offer 4G LTE nationally and 5G in core urban areas. Here is how they compare:
Viettel is the largest network with the best nationwide coverage. If you plan to travel outside major cities - to Ha Giang, Pu Luong, the Mekong Delta, coastal areas - Viettel is the most reliable option. In rural and mountainous areas, Viettel often has a signal where others do not.
Vinaphone (VNPT) has strong urban coverage and competitive data packages. Quality in major cities is broadly on par with Viettel. The SIM is widely available at VNPT offices and many convenience stores.
Mobifone is the third significant player with good urban coverage. Historically popular in HCMC and the south.
Recommended setup: Get a Viettel SIM on arrival for nationwide coverage and peace of mind. If you prefer to arrive connected, an eSIM for Vietnam via Airalo activates before you land.
Prices and Data Plans (as of 2025)
SIM cards are available at the airport on arrival (look for kiosks in the arrivals hall at Tan Son Nhat, Noi Bai, and Da Nang International) and from any phone shop or convenience store in the cities.
A Viettel SIM starter pack runs approximately 50,000 to 100,000 VND ($2 to $4). Data plan top-ups:
| Plan | Data | Price (VND) | Price (USD approx) |
|---|---|---|---|
| 30-day 30GB | 30GB | 149,000 | ~$6 |
| 30-day 60GB | 60GB | 199,000 | ~$8 |
| 30-day 100GB | 100GB | 249,000 | ~$10 |
| 30-day unlimited (throttled after 5GB/day) | Unlimited | 299,000 | ~$12 |
All plans include calls and SMS. Register the SIM with your passport (legally required) at point of purchase - the seller handles this. If buying from a phone shop rather than an airport kiosk, have your passport ready.
5G Coverage
5G is available in central areas of Hanoi, Ho Chi Minh City, and Da Nang. Viettel and Vinaphone both operate 5G networks. In practice, if your phone supports 5G you will connect automatically in these areas. Real-world 5G speeds: 200 to 600 Mbps. The 5G rollout is expanding but coverage outside major city centres is still primarily 4G.
Mobile Hotspot as Backup
A Viettel SIM on the unlimited plan (approximately 300,000 VND per month) makes a solid backup for your laptop when cafe WiFi is poor. Download speeds on 4G in HCMC and Hanoi regularly hit 40 to 80 Mbps. Tethering is permitted and works reliably.
Coworking Space Internet: What to Expect
Here is a breakdown of what reliable coworking spaces in each city offer:
Ho Chi Minh City:
- Dreamplex (Bui Thi Xuan / Dien Bien Phu / Binh Thanh): Dedicated 1 Gbps fiber, separate VoIP-optimized network for calls. $180 to $220/month.
- Toong Coworking (multiple locations): 500 Mbps fiber shared. Around $170/month.
- Base Camp (Nam Ky Khoi Nghia): 200 Mbps, reliable during business hours. Around $120/month.
Hanoi:
- Toong Coworking (Xuan Dieu): 300 to 500 Mbps. Around $120/month.
- Circo Coworking (Truc Bach): Dedicated fiber, ergonomic setups. Around $120/month.
- Up Coworking (Xuan Dieu): 200 Mbps, popular with the West Lake crowd. Around $100/month.
Da Nang:
- Enouvo Space (Vo Nguyen Giap): Dedicated 500 Mbps fiber. From around $100/month.
- CoGo Coworking (Nguyen Van Linh): Solid fiber connection. Similar pricing.
- The Hab (Pham Van Dong beach area): Good connection, beach proximity. Around $90/month.
Day passes at all of the above run 100,000 to 200,000 VND ($4 to $8). Worth buying a day pass before committing to a monthly membership to test the connection at your typical working hours.
Cafe WiFi
Vietnam has a strong cafe culture and most cafes offer free WiFi. Quality varies considerably. The safest bets:
- Cong Caphe (chain with multiple locations in all cities): Consistently reliable WiFi, USB charging points at most locations, atmospheric interiors. Speeds typically 20 to 50 Mbps.
- The Coffee House (chain, especially strong in HCMC): Good WiFi, air-conditioned, power outlets at most seats.
- Independent specialty coffee shops in Tay Ho (Hanoi), Da Nang beachfront, and HCMCβs District 3: Often have the best infrastructure and friendliest atmosphere for working. Look for shops with visible ethernet cables running to a router - usually a sign of a tech-conscious owner.
What to avoid: Very small local cafes with a single consumer-grade router shared across 30 seats. Fine for a 30-minute break, unreliable for a full working day. Also avoid hotel WiFi for important calls - hotel network management in mid-range properties is often poor, with significant packet loss even when headline speeds look adequate.
VPN Usage
Some work tools and certain websites require a VPN in Vietnam. A small number of services are blocked or intermittently restricted. The most common reason nomads use VPNs in Vietnam is for accessing geo-restricted streaming services and for security on public WiFi. Standard consumer VPNs (NordVPN, ExpressVPN, Surfshark, Mullvad) all work without issues. Connection to VPN servers in Singapore, Japan, or Hong Kong gives the lowest latency for Vietnam-based users.
Home Internet for Long Stays
If you rent an apartment for a month or more, getting a home fiber connection is straightforward and cheap. FPT Telecom and Viettel are the most common providers for residential installs.
Typical residential packages:
- 100 Mbps symmetric: approximately 250,000 to 350,000 VND per month ($10 to $14)
- 200 Mbps: approximately 350,000 to 450,000 VND ($14 to $18)
- 500 Mbps: approximately 450,000 to 600,000 VND ($18 to $24)
Installation typically takes one to three business days and requires a copy of your passport. Your landlord may need to co-sign. Most nomads using furnished short-term rentals find that the existing broadband is already set up and included in the rent.
Connectivity Outside Major Cities
Rural and trekking areas (Ha Giang, Sapa, Pu Luong, Phong Nha): 4G coverage exists but is spotty. Download a detailed offline map before heading out. Viettel is the most likely to have signal in mountain areas. Do not plan video calls from rural guesthouses.
Islands (Phu Quoc, Con Dao, Cat Ba): Mobile internet is available but slower than mainland. Phu Quoc has improved significantly with tourism development - most coworking-friendly cafes there have 20 to 50 Mbps connections. Con Dao is quieter and connectivity is more variable.
Overnight trains and buses: 4G is generally available along the main Hanoi to HCMC Reunification Express corridor. Expect some gaps through mountain tunnels and rural stretches. Tethering from your SIM works well for emails and messaging; avoid scheduling important video calls during train journeys.
Practical Tips
- Test your connection before a meeting: Use Speedtest.net or Fast.com to verify speed and latency before important calls. If a coworking space is falling short, switch to your mobile hotspot.
- Book a day pass before committing: Coworking space speeds during peak hours (9 am to 12 pm) differ from off-peak. Test first.
- Carry your SIM card hotspot as standard: A charged phone with a Viettel unlimited plan covers almost every connectivity emergency.
- Ask coworking spaces about dedicated Zoom lines: Several premium spaces have a separate SSID or LAN port with QoS prioritized for video calls.
- Renew your data plan on time: Viettel sends reminders. If you let the plan lapse, you will drop to a very slow default speed until you top up.
Vietnamβs internet infrastructure is a genuine asset for remote workers. The combination of fast coworking fiber, cheap and abundant SIM data, and a culture of cafe WiFi means connectivity is almost never a reason not to work productively.
Prices and plan availability correct as of mid-2025. Verify current data plan pricing at network provider retail stores or apps on arrival.
