Viettel eSIM 30-Day Plan: Pricing, Coverage for Long Stays
The Viettel 30-day eSIM, at USD 18.90 for 5GB per day, is the most cost-effective mobile data option for stays of three to four weeks. Direct from the carrier, this data-only plan provides ample connectivity for maps, video calls, and social media without the markup of global roaming. Here is a full breakdown of the pricing, coverage, and what to expect.
Pricing and Data Breakdown
The Viettel 30-day eSIM costs USD 18.90, delivering 5GB of high-speed data per day for 30 consecutive days. That totals up to 150GB of data, though actual usage depends on daily caps.
Data resets at midnight Vietnam time each day. Unused data does not roll over to the next day. Once you exceed the 5GB daily cap, speed is throttled to 128kbps until the reset. At 128kbps, messaging apps (WhatsApp, Telegram) remain usable, but video streaming and large downloads will be noticeably slow.
This plan is data-only: no phone number, no voice calls, no SMS. For voice communication, use VoIP apps like WhatsApp, Zalo, or FaceTime over the data connection.
Coverage and Network Reliability with Viettel
Viettel is the largest mobile network in Vietnam, with published ~99% population coverage (source: Viettel official site). It provides the most extensive 4G/5G coverage across the country.
In major cities (Hanoi, Ho Chi Minh City, Da Nang) coverage is robust, with typical 4G speeds ranging from 20 to 50 Mbps. Rural areas, including popular destinations like Sapa, Ha Giang, and Phu Quoc, still receive reliable 4G, though speeds often fall between 5 and 15 Mbps. Viettel is generally stronger than Vinaphone or Mobifone in remote mountainous regions, making it a preferred choice for trekkers and off-the-beaten-path travelers.
Who Should Buy the 30-Day Plan?
The 30-day plan is ideal for visitors staying three to four weeks – digital nomads, remote workers, or anyone on an extended vacation. At $0.63 per day, it is significantly cheaper than stacking shorter-term plans; for comparison, the Viettel 7-day plan costs $9.90 ($1.41/day).
5GB per day is sufficient for daily video calls (e.g., 2–3 hours on Zoom or Google Meet), maps navigation, social media scrolling, email, and web browsing. Heavy video streaming in high definition will quickly eat through the cap; if you plan to watch Netflix or YouTube for hours daily, consider whether the throttled speed (128kbps) is acceptable for messaging-only after the cap.
Viettel vs Vinaphone: Which 30-Day eSIM Is Better?
Vinaphone offers a 30-day eSIM with identical specs: 5GB/day at USD 18.90. Coverage is comparable in cities and along main tourist routes, but Vinaphone is slightly weaker in remote northern provinces like Ha Giang and Cao Bang. Viettel has a stronger footprint in those areas.
Mobifone (Skyfi) has plans up to 15 days (7GB/day) but no 30-day option, so it is not a direct alternative for month-long stays. For travelers who spend most of their time in cities, Vinaphone is a fine choice; for those heading to rural or mountainous areas, Viettel is the safer bet.
How to Install and Activate Your Viettel 30-Day eSIM
You can purchase the Viettel 30-day eSIM from simvietnam.telebox.vn; you will receive the QR code via email within 60 seconds. Install before departure: on iPhone go to Settings > Cellular > Add eSIM and scan the QR; Android users follow a similar process under Network & Internet > Add eSIM.
Activation happens automatically when you connect to a Vietnamese network upon arrival. Ensure your device is eSIM-compatible – most US and global iPhones (XS and later, except mainland China/HK/Macau variants) support eSIM. Note that iPhone 14–16 models sold in China, Hong Kong, and Macau do not have eSIM support. Also, carrier-locked phones from US carriers (e.g., AT&T, T-Mobile) may require unlocking before use.
