“connection was super easy. the site was really easy to buy off of. My family only use this from now on”
“not good.. in hanoi, showed lte in beginning then just went to 3g. spies were only 3g even when showing lte. thank god it was only $5, but still bad esim provider.”
“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.”
“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.”
“Does not work on my unlocked Pixel phone. Support couldn't give me any answer. Ended up buying from Bytesim and that worked instantly.”
“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.
”
“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 190 travel eSIM providers and roughly 11 500 prepaid data plans. This wide array of options makes it easy for travelers to find an eSIM that suits their needs.
Are there any unlimited data eSIM plans available for Vietnam?
Unlimited data eSIM plans for Vietnam are available from several providers. The following offer no data cap, though speed may be throttled or limited to a specific maximum: abesteSIM, MicroEsim, ASIMGO, Giga.Tel, Roamify, Earth Esim, Yesim, Truely, EtravelSIM, Ohayu and Orange Travel. For those that specify a speed limit, abesteSIM, MicroEsim, Giga.Tel and Truely have a 10 Mbps cap, Earth Esim has a 5 Mbps cap and Ohayu a 1 Mbps cap; the other plans simply state that speed may be throttled. Tethering is typically allowed on most plans. Prices for these unlimited options range from approximately $1.91 up to $35.99, depending on the provider and validity period (1‑30 days in most cases). This gives travelers a broad selection to choose from based on budget, desired speed, and duration of stay.
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 eSIM plans that provide a phone number and SMS for Vietnam are available from several providers. eSIMX, MicroEsim, ChillaxSIM, simvietnam, and GlobaleSIM offer local numbers with the Vietnamese dialing code +84, while other plans such as Giga.Tel and Orange Travel give foreign numbers with codes +7 or +48 but still support inbound and outbound voice calls and SMS. The plans range from 7 to 30 days of validity, with data allowances from 1GB up to 50GB and prices starting around $4–$6 for basic packages.
If a local phone number is preferred, eSIMX, MicroEsim, ChillaxSIM, and simvietnam provide direct +84 numbers, which are useful for traditional SMS, voice calls, and local billing. Plans with foreign numbers can still fulfill the same function but may incur international calling rates. Travelers who only need data can use data‑only eSIMs and rely on VoIP apps such as WhatsApp or Telegram; however some of these services are sometimes restricted in Vietnam, so it is advisable to confirm app availability before purchasing.
