Vietnam eSIM 30 Days vs Unlimited Plan: Which One Should You Choose?
When planning your trip or remote work stay in Vietnam, one of the most important decisions is whether to get a Vietnam eSIM 30 Days plan or an Unlimited Plan. Both options have their strengths, but choosing the wrong one can mean paying more than necessary or running out of data when you need it most. This guide breaks down the differences, pros, and ideal use cases for each plan so you can pick the one that fits your lifestyle.
📌 What Is a Vietnam eSIM 30 Days Plan?
The Vietnam eSIM 30 Days plan is a prepaid mobile data option that gives you a fixed amount of high-speed data valid for 30 days from activation. It’s a popular choice for tourists, digital nomads, and business travelers who know their approximate data needs and want predictable costs.
- Typical data allowance: 10GB, 15GB, or 30GB high-speed.
- Validity: 30 consecutive days.
- Speed: Full 4G/5G until your limit is reached, then reduced to 128–256 kbps.
- Top-up option: You can add more data if needed.
- Example provider: GoVnSIM Viettel eSIM 30 Days.
📌 What Is a Vietnam Unlimited Plan?
The Vietnam Unlimited Plan offers continuous internet access without worrying about exhausting your data quota. However, most “unlimited” packages have a fair usage policy (FUP) where speeds are reduced after a certain daily or monthly threshold.
- Typical structure: Unlimited with 2GB–5GB/day at full speed, then slower speeds.
- Validity: 7, 15, or 30 days depending on the package.
- Speed: 4G/5G until you hit the FUP, then throttled to ~256 kbps.
- Top-up: Usually no top-up needed—your speed resets daily.

💡 When to Choose Vietnam eSIM 30 Days
You should consider a 30-day fixed plan if:

- You want a lower, predictable monthly cost.
- You stay in Vietnam for the full month without major daily streaming needs.
- You’re okay with buying top-ups if your usage changes.

The unlimited plan might be better if:
- You regularly stream HD/4K content, upload large files, or host live broadcasts.
- You run a mobile hotspot for multiple devices.
- You have unpredictable daily usage that could spike.
- You don’t want to monitor your data usage constantly.
📊 Cost Comparison Example

- Vietnam Unlimited – 30 days, 5GB/day full speed: $25 USD
- Note: Unlimited plans may cost 40–80% more, but give peace of mind for heavy users.
🌍 Data Usage Scenarios
To help you decide, here’s how each plan performs in real-life cases:
Case Study 1 – Digital Nomad in Ho Chi Minh City
Anna, a remote worker, uses 1–1.5GB/day for Zoom, Slack, and browsing. A 15GB/month plan covers her needs perfectly, costing less than an unlimited plan. She only topped up once during a particularly heavy week of uploads.
Case Study 2 – Family Traveling Across Vietnam
A family of four tethering multiple devices while on trains and buses easily hit 5–6GB/day. They chose the unlimited plan to avoid constant top-ups and had smooth streaming for the kids during long rides.
🛠️ Step-by-Step: How to Choose & Activate

📢 Final Recommendation
Choosing between Vietnam eSIM 30 Days vs Unlimited Plan comes down to your daily data habits. If you’re a moderate user who values a lower monthly cost, the 30-day plan is the smart pick. If you need high-speed data every day without limits, the unlimited plan gives you peace of mind—just expect to pay more. Either way, buying from a trusted provider ensures a smooth activation and reliable service throughout your stay.
