“connection was super easy. the site was really easy to buy off of. My family only use this from now on”
“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.”
“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.”
“I received a Viettel esim and it worked without any problems throughout 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.”
“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.”
“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.”
“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.”
“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'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.”
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?
Vietnam offers more than 200 travel eSIM brands and over 13, 400 prepaid data plans, giving travelers a wide range of options to suit their needs.
Are there any unlimited data eSIM plans available for Vietnam?

The available providers include abesteSIM, ASIMGO, MicroEsim, Roamify, Yoho Mobile, Earth Esim, Giga.Tel, Yesim, Truely, EtravelSIM, GIGAGO, Bloomy eSIM, Ohayu, and Orange Travel. All of these plans provide unlimited data for validity periods ranging from 1 to 30 days, and are delivered over 5G networks. Each plan permits tethering; however, most include a note that speed may be throttled. Typical speed limits are 5 to 10 Mbps, with Ohayu offering only 1 Mbps. Prices for unlimited data plans vary from about $1.92 to $22.00 USD, giving travelers a range of options to choose from based on their budget and desired usage duration.
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, several travel eSIM providers offer plans for Vietnam that include a phone number and SMS capability. Providers such as GlobaleSIM, eSIMX, MicroEsim, Kimlik eSIM, Kovitel, Orange Travel, and eSIMX Global list phone numbers and SMS in their Telephony details. The local Vietnamese dialing code (+84) is used by eSIMX, MicroEsim, Kimlik eSIM, and Kovitel, giving travelers a local number for calls and SMS. Other plans use foreign dialing codes: GlobaleSIM uses +1, Orange Travel uses +48 or +33, and eSIMX Global uses +376, so the number is not local to Vietnam but still provides voice and SMS services.
Prices for these plans start around $4 for a 7‑day data‑only plan with a local number and rise to about $85 for a 30‑day plan with 100 GB of data. Validity periods range from 5 days to 30 days, with some options extending to 60 days. Inbound SMS is available on all listed plans, while outbound SMS is included on most but not all; voice calls are supported on the local‑number plans and on some foreign‑number plans. Travelers should confirm that the VoIP or messaging apps they rely on are accessible in Vietnam before purchasing.
