Local Pricing Context
Vietnam's mobile market is dominated by three carriers — Viettel, Mobifone, and Vinaphone — all offering incredibly cheap prepaid SIM cards for tourists. Hanoi's Nội Bài International Airport has official kiosks for all three carriers in the arrivals hall, where a tourist SIM with 10–15 GB of 4G data for 30 days costs VND 100,000–200,000 (roughly $4–8 USD). This is already one of the cheapest mobile data markets in Southeast Asia.
Viettel is the largest carrier with the best nationwide coverage, particularly important if you're traveling beyond Hanoi to Sapa, Ha Long Bay, or Ninh Binh. Their tourist package "VT30" provides 3 GB/day (effectively unlimited for normal use) for 30 days at VND 150,000. Mobifone's "MF200" plan offers similar data at VND 200,000 but includes 50 minutes of domestic calls. Vinaphone tends to be slightly cheaper but has marginally weaker coverage in rural areas.
In the Old Quarter, dozens of mobile phone shops along Hàng Bạc and Hàng Gai streets sell SIM cards. Prices here are negotiable and often cheaper than the airport — VND 50,000–100,000 for a SIM with 5–10 GB. However, quality varies: some shops sell legitimate SIMs while others resell deactivated or recycled ones. Stick to shops displaying official carrier branding.
Vietnam requires passport registration for SIM purchases. Airport kiosks handle this instantly; street shops may photograph your passport or ask you to register via the carrier's app. This is legitimate and legally required.
eSIMs are increasingly viable in Hanoi. Airalo offers Vietnam plans from $3.50 USD for 1 GB / 7 days, while Holafly's unlimited plan runs about $5 USD/day. Given how cheap physical SIMs are in Vietnam, eSIMs only make sense for very short trips or travelers who don't want to swap their home SIM.
Free WiFi is ubiquitous in Hanoi — virtually every café, phở shop, and hotel offers it. The Old Quarter has WiFi coverage from many businesses that's accessible from the street. Vietnamese coffee shops are essentially coworking spaces with excellent connectivity.
How to Avoid Overpaying
- 1Airport SIM kiosks are already cheap at VND 100,000–200,000 — don't stress about getting ripped off there
- 2Viettel's 'VT30' plan at VND 150,000 gives 3 GB/day — effectively unlimited for a month
- 3Old Quarter phone shops sell SIMs for VND 50,000–100,000 but verify the SIM is new and activated before paying
- 4At $4–8 USD for 30 days of data, physical SIMs beat eSIM pricing for any stay over 3 days
- 5Free WiFi in Vietnamese cafés is excellent — you may not even need heavy data if you're mostly in the city
