Vietnam eSIM price cycles
How Vietnam eSIM prices shift throughout the year.
Vietnam seasonal trends
Vietnam sits among the cheapest mobile data markets in the world and prices stay flat throughout the year. Peak season: Oct-Apr. No provider in this site's offer file ties a discount to those months.
What drives Vietnam eSIM pricing
- Wholesale data cost: Vietnam's operators charge providers for bulk data, and that cost sits under every plan price.
- Provider competition: 5 providers sell eSIMs that travelers compare for Vietnam. More competition means lower prices for travelers.
- Plan tier: Larger plans cost less per GB. The Vietnam 20GB plan drops to $1.37/GB.
Where the Vietnam price floor sits
The catalogue holds 5 Vietnam plan sizes. The lowest rate is $1.37/GB in the 29 Oct 2026 catalogue. This site records list prices and does not forecast where they go next.
Price vs value analysis
The cheapest price is not always the best deal. Here is how each offer stacks up on real value.
Carrier roaming vs eSIM deals
This site compares every destination against a $10/day roaming baseline, so a 7-day trip runs $70.00. The lowest catalogue price for the same week is $27.49, saving $42.51 (61%). Apply a promo code to widen the gap further.
Post-discount net price comparison
| Provider | Base Price | Discount | Net Price |
|---|---|---|---|
| Nomad | $25.00 | up to 20% off | $20.00 |
| Airalo | $28.00 | ALOHA (up to $5 off) | $23.00 |
| Saily | $28.99 | up to 10% off | $26.09 |
| HelloRoam | $27.49 | No code needed | $27.49 |
HelloRoam's base price is its catalogue price. Each rival's base price is its own 20GB price for Vietnam, read on 30 Oct 2026, with its published promotion applied to that figure. Holafly is not listed here because it sells unlimited day rates rather than fixed plans.
For the 20GB plan, Nomad is lower after its offer, at $20.00 against HelloRoam's $27.49.
Compare the NET column, not the discount percentage. The lowest post-discount price wins.
Fixed vs unlimited deal value
The 20GB plan at $27.49 covers 14 days at 1.5 GB/day. The unlimited plan costs $4.43 for one day, with 2 GB a day at high speed. Unlimited wins above 15.5 GB/day. Below that threshold, the fixed plan is the better value.
Discount codes and how to use them
Every active code with Vietnam-specific net prices.
Active codes price snapshot
| Provider | Code/Link | Discount | Conditions | Net Price (Vietnam) |
|---|---|---|---|---|
| HelloRoam | None needed | No standing code: the catalogue price is the price | Billed in 31 checkout currencies | $3.49 |
| Saily | Partner link | up to 10% off during seasonal sales | Seasonal promotions, Black Friday | $3.59 |
| Airalo | ALOHA | up to $5 off a first purchase | First purchase only | $0.00 |
| Nomad | Partner link | up to 20% off on select regions | Monthly flash events, in-app only | $3.20 |
| Holafly | Partner link | 5% off, applied automatically via partner link | Via partner/affiliate link | $26.13 |
The top pick publishes no standing discount code and bills checkout in 31 currencies, so its row's net price is the catalogue price.
Offers as each provider published them, June 2026. Net prices apply each offer to that provider's own Vietnam price, read on 30 Oct 2026; N/A means no price was read.
How to apply each code
- Airalo (ALOHA): Visit airalo.com. Select a Vietnam plan. Enter ALOHA at checkout. Discount applied.
- Holafly (Partner link): Use the partner link above. Select Vietnam. The 5% off discount applies with no code to type.
- Saily (Seasonal): Check saily.com for an active sale banner. Select a Vietnam plan. The sale price shows at checkout.
- Nomad (Flash sale): Open the Nomad app. Check the flash sale banner. Select Vietnam. The discounted price shows if the sale is active.
Stacking discounts
No provider allows stacking multiple codes. One discount per order. The best strategy: compare the final price (after discount) across all 5 providers. The cheapest post-discount price wins, not the highest percentage off. Example: Airalo 1GB at $4.00 minus $5 = $0.00. The 7-day unlimited plan for Vietnam costs $27.29.

When Vietnam eSIM deals are cheapest
Vietnam sits among the cheapest mobile data markets in the world and prices stay flat throughout the year.
Peak travel season in Vietnam: Oct-Apr. The best travel window shifts by region: the north runs October to April, while the south stays dry from November to April.
Vietnam eSIM price positioning
Vietnam falls into the budget-friendly category for eSIM data. At $1.37/GB, Vietnam sits 57% below the global average of $3.20/GB. 3 carriers (MobiFone, Viettel Mobile, Vinaphone) provide the underlying 5G infrastructure.
5 plan tiers are tracked for Vietnam, from 1GB ($3.49, $3.49/GB) to 20GB ($27.49, $1.37/GB). The volume discount from smallest to best-value tier is 61%. The largest tier also delivers the best per-GB rate.
Unlimited data for Vietnam is tracked at $4.43/day. Full 5G speed runs for 2GB per day before throttling. Multi-day commitments drop the daily rate: the 30-day plan runs $3.01/day (32% off). The crossover point sits at 3.2GB/day: below that, the 20GB fixed plan saves money; above it, unlimited wins.
A Viettel SIM costs about $3 for 6GB over 30 days, which undercuts most travel eSIM providers by a wide margin, though the registration process takes extra time. Viettel reaches the remote northern mountains where both Vinaphone and Mobifone lose signal, so it is the practical first choice for off-the-beaten-track trips.
Budget verdict: Vietnam is a great-value eSIM destination. Data costs are low enough that even over-buying a tier wastes only a few dollars.
Cost-saving strategies for Vietnam
- Buy the 20GB tier instead of 1GB
The 1GB plan costs $3.49/GB. The 20GB plan drops to $1.37/GB. On 10GB of total usage, that saves $21.20. The upfront cost is higher ($27.49 vs $3.49), but the per-GB savings more than compensate if you use 50% or more of the plan's data.
Estimated savings: $2.12/GB, $21.20 on 10GB
- Use WiFi for heavy tasks in Vietnam
WiFi in Vietnam is rated good. Cafes and hotels in tourist areas almost all offer free WiFi; Vietnam attracts a large digital nomad crowd and the infrastructure reflects that. Download maps, sync photos, and stream video on WiFi. Reserve cellular data for outdoor navigation and messaging. This lets you buy a smaller, cheaper eSIM plan that covers only your outdoor data needs.
Estimated savings: 30-50% reduction in data consumption
- Skip the Tan Son Nhat (SGN) / Noi Bai (HAN) SIM counter
Airport SIM counters charge $5-15 for 6-20GB / 15-30 days. Queue time: 10-15 min. A travel eSIM starts at $3.49 for 1GB with zero queue. Install before departure and connect on landing. The saved queue time means more time at your destination and less at a kiosk.
Estimated savings: 10-15 min saved, potentially lower price
- Activate on arrival to maximize validity days
Most Vietnam eSIM plans start counting from first connection to a MobiFone tower. Install the eSIM at home over WiFi, but keep the cellular line disabled until you land. Activating a 7-day plan 2 days early wastes 2 days of validity. Every day of your plan should align with actual travel days.
Estimated savings: 0-2 extra valid days per plan
- Turn off carrier data roaming before departure
This site compares Vietnam against a $10/day roaming baseline. Forgetting to disable roaming costs $70.00 for a week of accidental data use. A plan covering the same week costs $27.49, 61% less. Go to Settings > Cellular > turn off Data Roaming on your home carrier line before your flight.
Estimated savings: $42.51 per 7-day trip
- Consider Asialink bundle for multi-stop Asia trips
Airalo's Asialink regional bundle covers 16 Asian countries on a single eSIM from $5.00 (1GB). If Vietnam is one of 2+ stops in Asia, compare the bundle price vs buying individual plans at $3.49 each. The bundle typically saves money from the third destination onward. One eSIM, one purchase, multiple countries.
Estimated savings: Varies; typically saves from 3+ countries
Hidden costs when buying Vietnam eSIM deals
- SIM registration: Vietnam requires ID registration for physical SIMs. An eSIM avoids this entirely.
- VPN restrictions: VPN usage is restricted in Vietnam. VPNs occupy a legal gray zone; the government blocks many VPN providers at the network level, though Facebook and Google stay accessible for most visitors.
- Carrier roaming markup: At this site's $10/day roaming baseline, a 7-day trip in Vietnam runs $70.00, against $27.49 on the catalogue plan that covers 1.5 GB a day.
