Terrible experience. No connection most of the time, or extremely slow connection. No 5G at all.

Never got 5g connection. Connection was often lost in Hanoi and switched from LTE to 3G. Contacting customer service was not helpful as they will greet you but will not respond otherwise.

Chrisused in Vietnam 🇻🇳

I was looking for a 5GB x 15 days Viettel SIM and most websites said this package was "soldout". ChillaxSIM had it in stock but the site looked kind of sketchy. The price was low enough to give it a try and it worked great! I added the eSIM from the QR code when I was still in the states with WiFi. While it appeared on my service list it wouldn't activate. As soon as I landed in Vietnam, activation completed and the service worked perfectly (no WiFi needed). I had service in all areas we visited, even rather remote. Compared to some of my travel partners who paid per day as much as my 15 day package was, I highly recommend!

Absolutely fantastic experience. My Vietnam eSIM activated the moment I landed, and the data was fast and reliable everywhere I went. Setup was effortless, and I stayed connected without a single hiccup. Perfect for hassle-free travel—highly recommended.

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.

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.

WARNING! This eSim Provider will throttle your data! Bought 100GB/20Days and got throttled after 9-10GB. Support not answering, terrible experience overall.

The QR code didn't work and after a few emails they issued a new code. After enabling the card and used for a few hours, it got disabled. Every time the support would ask for a lot of useless information.

Lauraused in 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.

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

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.

The carrier is Vietnammobile. I knew it's not the best one but I didn't expect the reception is that bad. I used in Da Nang. It's not very stable and fast. May not load fast in some areas. When you are going to some remote area / on a ride, it might not get any signal at all. Comparing to my friends using Viettel, they're completely fine at all time.

Ubigi

ぼくused in 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

skused in 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

skused in 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

lucasn0tchused in 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.

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.

Frequently Asked Questions

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

Vietnam offers more than 120 travel eSIM providers and over 5, 800 prepaid data plans, providing a wide variety of options that make it easy for travelers to find an eSIM that suits their needs.

Are there any unlimited data eSIM plans available for Vietnam?

Yes, unlimited data eSIMs are available for travelers to Vietnam from several providers. MicroEsim, Yoho Mobile, Billion Connect, abesteSIM, Roamify, Truely, Yesim, Airhub, and esimzon all offer unlimited data plans that cover 1‑30 day periods. Most plans allow tethering; a few specify speed limits, with MicroEsim providing up to 10 Mbps, Yoho Mobile and abesteSIM capping speed at 5 Mbps, and the remaining plans noting that speeds may be throttled during high‑usage periods. Network coverage varies from 4G to 5G and LTE, with Truely also including 3G. Prices for these unlimited options range from about $2.25 to $40.35 USD, depending on provider and validity length.

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?

Yes, travel eSIMs that include a phone number and SMS for Vietnam can be obtained. Providers such as MicroEsim and abesteSIM offer plans that deliver a local Vietnamese phone number with the +84 dialing code; these plans provide inbound and outbound voice and SMS, allowing you to make and receive calls and texts just like a local SIM.

Other providers, including GlobaleSIM and Roamify, also offer travel eSIMs with phone number and SMS capabilities for Vietnam, but their numbers use the foreign +1 dialing code. These plans generally allow inbound and outbound voice and usually support inbound SMS, though some offer outbound SMS as well. Prices and validity periods vary across the plans, with options ranging from a few days to several weeks and data limits from 1 GB to 50 GB.
