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.

Does not work on my unlocked Pixel phone. Support couldn't give me any answer. Ended up buying from Bytesim and that worked instantly.

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.

TravelGator eSIM

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.

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

Bienused in 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.

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.
