“Bought their Vietnam eSIM with Viettel number. Was extremely good. I believe it's exactly the same as prepaid Viettel SIM product available to tourists at the airport, just in eSIM form. Excellent Ping (below 50ms), fast speeds. Solid choice.”

eSIMX Vietnam

“At first there were problems with activation, it took several hours.
I used eSIM for 2 weeks. Internet works only in the center of large cities, on the outskirts and in small towns the connection completely disappears, or is very, very slow. Support does not respond.”

TravelGator eSIM Vietnam

“Had to wait more than 30min to get the QR code after purchase, so it’s not instant delivery and it might be troublesome for people in a hurry to get online.

It took a while to get connected to Viettel network first. The speed was okay but the latency is crazy high, given the IP address is from Singapore. I had to manually change the network to MobiPhone to get better connection. Definitely not beginner-friendly.
It’s one of the cheap options but not sure if it’s worth a try. I wouldn’t choose this provider next time.”

Textr eSIM Vietnam

“Update from previous rating...
Customer support slowly but finally responded: full refund as store credit - valid for one year. Thus, not feeling so bad with the purchase.”

Textr eSIM Vietnam

“Bad! Bad! Bad!
1. At the capital, on street open sky, connection down speed is in single digit Mbs, upload in hundreds kbs.
2. Going out on highway and attraction areas: just like 2G - if there is connection.
3. Sending emails to support, for 2 full days: no response.
4. Bought a 20Gb/60 days eSim: asked for partial refund of remaining dara: silent so far.

Don't be fool, like me, for the low price.

Actually i bought a package at a local viettel store: better connection and cheaper for 60 days.

Ubigi Vietnam

“In Hanoi and Da Nang city areas, the connection was slow and occasionally cut off, but I managed to use it somehow. However, around the Naman Retreat Hotel, it was almost unusable. In the end, I had to ask the hotel staff to guide me to a store where I could buy a local SIM card for travelers.

I purchased 10GB for 7 days, but I didn't even use 1GB.”

EtravelSIM Vietnam

“Although the eSIM I purchased from ETravelSim was cheap, it was provided by Vietnamobile, and the speed was slow and the coverage wasn't very good either (especially in Nha Trang). I also didn't know how to check the remaining data because it was not clear in the instruction provided.
It might be okay if you are staying in HCMC or Hanoi, but not ideal if you are traveling other smaller cities.

The eSIM I got from GIGAGO, which connects to Vinaphone, was much better.”

GIGAGO Vietnam

“Bought an eSIM with 10GB of data from GIGAGO but it's actually provided by iTel, a Vinaphone MVNO in Vietnam. It's a local connectivity, not a typical roaming eSIM, and both the speed and latency are quite good. Although setting up the APN for personal hotspot was a bit of a hassle, overall, I am very satisfied and can recommend it.”

Ubigi Vietnam

“Ubigi's eSIM plans for Vietnam really falls short for several reasons.

1. The connection keeps on dropping randomly. This is unacceptable when you need to call your family using WhatsApp, Viber, or Zalo, and you suddenly disconnect.
2. I was assigned a mainland Chinese IP address with a Singaporean DNS. This is also unacceptable due to privacy concerns and certain sites blacklisting my eSIM.

Eventually, I switched over to a Viettel eSIM from MobiMatter, and it worked flawlessly for the rest of my family trip to Vietnam. Would not recommend Ubigi for Vietnam.”

Airalo Vietnam

“The internet was terrible. To make it work, I had to turn on and off flight mode. Then it would work for 2 minutes and stop working. I had to do this right now while writing this review. Would never purchase again. I am using an iPhone 12 and I never had any issues with eSIMs before.”

Vietnam Travel eSIM FAQ

Everything you need to know about using eSIMs in Vietnam

How many travel eSIM brands (providers) are available for use in Vietnam, and how many prepaid data plans are there?

More than 220 travel eSIM providers and more than 15, 300 prepaid data plans are available for Vietnam, giving travelers a wide range of options to find an eSIM that suits their needs. With such a broad selection, travelers can choose a plan that best fits their usage and budget.

Are there any unlimited data eSIM plans available for Vietnam?

Unlimited data eSIM plans are available for travelers heading to Vietnam from several providers. The following companies offer unlimited data: ASIMGO, Earth Esim, abesteSIM, MicroEsim, Roamify, Yesim, EtravelSIM, esimzon, GIGAGO, and Orange Travel. All these plans come with a permissible validity period ranging from one to thirty days. Speed may be throttled on most plans; some specifically cap speeds at 10 Mbps (ASIMGO, abesteSIM, MicroEsim, esimzon), 5 Mbps (ASIMGO, abesteSIM, MicroEsim, esimzon, Earth Esim, GIGAGO), or 1 Mbps (Earth Esim), while others do not specify a fixed limit. The price spectrum for these unlimited options spans from roughly $1.98 to $26.00 USD, with most providers pricing between about $2 and $25. These plans allow tethering, though eKYC may be required for a few of them (e.g., esimzon and Orange Travel).

What are the major mobile networks available for a travel eSIM in Vietnam?

Vietnam's mobile network infrastructure is primarily supported by the following major Mobile Network Operators (MNOs):

Viettel: The largest telecommunications provider in Vietnam, offering extensive nationwide coverage.
MobiFone: A major state-owned enterprise providing mobile services across the country.
VinaPhone: A core subsidiary of the state-owned Vietnam Posts and Telecommunications Group, offering comprehensive mobile services.
Vietnamobile: A private mobile network operator, recognized as the fourth largest provider in Vietnam.

In addition to these MNOs, Vietnam has several Mobile Virtual Network Operators (MVNOs) that offer mobile services by leasing access from major carriers. Notable MVNOs include iTel, Wintel, myLocal, VNSKY, and FPT SIM. It's important to note that most travel eSIMs rely on the infrastructure of MNOs rather than MVNOs.

Can I get a travel eSIM with a phone number and SMS for Vietnam?

Travel eSIM plans that include a phone number and SMS are available for Vietnam. The providers that offer such options in the data set are GlobaleSIM, eSIMX, GIGAGO, MicroEsim, SogdiaRoam and a few others. Most of these plans use a foreign dialing code, notably +1, which gives you a U.S.‑style number rather than a local Vietnamese number. Plans that use the Vietnam dialing code +84 – such as the eSIMX, GIGAGO, MicroEsim and SogdiaRoam offerings – provide a local Vietnamese number. Call and SMS capabilities vary: the +1 plans support inbound and outbound voice and inbound SMS, while the +84 plans typically allow inbound voice and SMS; some +84 plans also offer outbound voice, and several plans include both inbound and outbound SMS. Prices for these plans start around $4.00 USD for a 1 GB, 7‑day period, with validity ranges from 5 to 30 days and data capacities from 1 GB up to 50 GB, depending on the provider and plan size.
