In Vietnam, Mobile Internet Is Your Best Defense Against Information Asymmetry

Vietnam is one of Southeast Asia's most rewarding destinations — and one of the most challenging to navigate without reliable internet. Taxi overcharging, restaurant menu price inflation in tourist areas, and market vendor markup are all well-documented realities in Hanoi and Ho Chi Minh City. A connected phone is your most effective tool: Google Maps lets you know the real distance before you get in a taxi; Google search reveals the correct price range for any restaurant; online ticket booking eliminates scalper premiums at major attractions. The experience gap between connected and unconnected travelers in Vietnam is larger than almost anywhere else in Southeast Asia.

Vietnam's mobile network is led by Vietnamobile and Vinaphone, with solid 4G coverage across Ho Chi Minh City, Hanoi, Da Nang, and major tourist cities. Roaming2's Vietnam eSIM connects you from the moment you land at Tan Son Nhat or Noi Bai, bypassing airport SIM card queues entirely.

Three Cities, Three Completely Different Experiences

Ho Chi Minh City (Saigon): One of Southeast Asia's most kinetic cities. Grab is the only safe taxi option for foreign visitors — street taxis in tourist zones have well-known overcharging patterns. Grab also covers motorbike taxis (Xe Om) with transparent pricing. Network coverage in District 1 and District 3 city center areas is consistently solid.

Hanoi: A slower pace with a deeply walkable Old Quarter around Hoan Kiem Lake — but the street layout is genuinely labyrinthine, making Google Maps essential rather than optional. Hanoi's café culture is extraordinary; free WiFi is everywhere, but the speed and reliability of public networks is inconsistent. Your own eSIM data is always more dependable.

Da Nang and Hoi An: Da Nang is Vietnam's beach resort hub; Hoi An's Ancient Town is UNESCO-listed and deservedly famous. Both have good coverage. The mountain road to Ba Na Hills cable car station has intermittent signal in sections.

Vietnam's Specific Data Drain: Street View for Hidden Alley Entrances

Vietnam — particularly Hanoi's Old Quarter and Ho Chi Minh City's back streets — has an extraordinary density of restaurants and cafés hidden in unmarked alleys with no visible signage from the street. Travelers routinely use Google Maps Street View to confirm the correct entrance, more frequently than in almost any other destination. Budget accordingly.

Data Recommendations

  • Single city, 5–7 days (5–10GB): Grab, Google Maps, attraction lookups — 10GB is safe
  • North-south traverse or multi-city (10–15GB): Inter-city travel plus heavy photography — 15GB is the right target
  • Extended stay or digital nomad (20GB+): Vietnam is a popular remote work base — work plus daily life needs 20GB or above

Frequently Asked Questions

What you most want to knowIt's all here.

Purchase and Activation
Select your destination plan on the website, add it to your cart, and proceed to checkout. We accept credit cards (Visa/Mastercard), Google Pay, and Apple Pay. After payment is completed, the system will automatically send a confirmation email to your inbox within 60 seconds. This email contains a QR code and installation instructions.
Within approximately 1 minute after successful payment, the system will automatically send the confirmation to your email. The entire process requires no manual intervention and is available 24 hours a day. If you haven't received it after 5 minutes, please first check your spam folder or contact our customer service for a resend.
Yes. After purchase, the eSIM can be stored for up to 180 days. We recommend purchasing it in advance. Once you receive the QR code, save it for later. You can activate it on your departure day or after arriving at your destination.
Device Compatibility
The quickest way is to dial *#06#. If an EID number appears, it indicates support. Commonly supported models include iPhone XS/XR or later (including SE 2/3), Samsung Galaxy S20 or later, and Google Pixel 3 or later. Please note that some mainland China/Hong Kong versions of iPhone and Samsung Hong Kong versions (pre-S26) do not support eSIM.
→ View the full list of supported models
Yes. Most supported phones let you use a physical SIM and eSIM at the same time. Keep your original SIM for calls while using the eSIM for data — no missed messages while traveling.
Installation and Setup Guide
We recommend completing the installation on the day of departure or while waiting at the airport, using a stable Wi-Fi connection. Upon arrival at your destination, simply activate the eSIM and enable "Data Roaming" to connect to the internet.
Please verify the following: 1) The eSIM number is activated; 2) The "Mobile Data" source is switched to this eSIM; 3) Ensure "Data Roaming" is enabled; 4) Confirm the eSIM status via the link in the email. If no signal is detected, try toggling Airplane Mode to prompt your phone to rescan.
Don't worry, our eSIM supports rescan. You can re-add the eSIM using the information in your purchase confirmation email before your data plan expires. However, to avoid service interruptions, we still recommend not deleting it after installation.
Traffic, Internet Speed, and Computing
No. Our plan activation begins when you use the first 1MB of data. Additionally, a day is defined as a continuous 24-hour period, not reset at midnight. This ensures you receive a full 24 hours of usage time.
This depends on your plan type. After exhausting your daily data allowance, "Daily Data Plans" typically enter a throttled state (most plans throttle to 1Mbps, sufficient for messaging apps and map navigation), with full speed restored after 24 hours. "Total Data Plans" cease service once the allowance is depleted. For specific details, please refer to the "Throttling Policy" on the data usage inquiry page.
Most plans support hotspot sharing. However, please note that Fair Usage Policies (FUP) apply to all plans. Downloading extremely large amounts of data within a short period (such as 4K videos or system updates) may trigger temporary speed throttling by your carrier.
You can access the inquiry page via the exclusive link in your purchase confirmation email to instantly view detailed information such as "remaining data allowance," "eSIM status," and "throttling policy."
Refunds and After-Sales Service
Yes. As long as your eSIM has not been installed, or has been installed but not activated (has not consumed any data), you may request a 100% full refund within 30 calendar days from the date of purchase.
Yes. If the service is already activated but needs to be interrupted for any reason, you may apply for a "pro-rated refund." We will calculate the refund based on the proportion of unused data (if the refund amount is less than 2 USD, the company reserves the right to convert it into store credit).
Once an internet plan expires, no refunds or compensation will be provided regardless of whether the data allowance has been fully used.
