Overall it was a pleasant experience. Purchase and setup was quick and easy. Will use again if needing a short term Esim for travel.
Their eSIM works on the 3 (Tri) network, which isn’t as strong as TSEL but offered mostly decent coverage. Speeds were solid, with latency under 100ms (better than I expected). Not much to complain about. Can recommend.
I’ve used Billion Connect for multiple eSims abroad now, and I’ve found them great every time. Their customer service responds pretty quickly to any issues, and the sims are cheap and work well. Be aware the sims are mostly based in Hong Kong so if you’re geographically far from there the latency might be a little high, and you may need a VPN for things like TikTok to work, but I’ve had very few issues.
In terms of speed it wasn’t particularly fast or slow, just average. The connection was mostly through SIMBA, but in some locations it switched to StarHub. The biggest drawback was that, since it was roaming via Hong Kong, I couldn’t use ChatGPT.
The sim worked fine, but be aware that Yoho count their days as 00:00-23:59, so if you buy a sim in the afternoon or evening, the last few hours of that purchase day will count as 1 day. I was cut off nearly a full day early because I bought it in the evening.
Supera link functioned perfectly for me in Singapore when i visited last march, providing 5G coverage across the whole city on the local du network
But when visiting smaller island nations, you might find that the local networks have limitations. It's worth thinking about how internet access is provided to these little islands
It seems the roaming provider has changed from Singtel to KPN. As a result, data now routes through the Netherlands, thus higher latency than before (200+ms). It connects to Smart network. There were several occasions when the signal dropped to "E" (Edge), and data could not be used. This might be due to local coverage issues. The latency is still manageable, but the occasional loss of connectivity is a bit inconvenient. I wouldn't recommend it.
Worked great 95% of the time. Speeds were 100+mbps in most areas in all the countries I visited. Ping was around 60-200ms.
Two downsides:
1. ChatGPT or apps blocked in Hongkong do not work anymore without VPN
2. In very crowded places internet would slow down a lot
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.
The speed is horrible. Speed at 10 Mbps - 500 GB is useless at this speed
The speeds are decent, but the IP is from Hong Kong so the latency is quite high. And most importantly, ChatGPT cannot be used unfortunately.
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.
This is an update of my review. In the end I did receive the eSIM via the support chat.
Fraud, payment was accepted but eSIM was not shown. They wrote in the support chat that they sent it to the email address (where the receipt was received), and after a while stopped replying
technically functional but extremely slow speed
Really good experience and great price. Support was really fast and helpful
Easy to use, decent speeds (not particularly fast but not frustratingly slow either). But this eSIM uses roaming via Hong Kong, so I wasn't able to use ChatGPT which was a bummer.
I received a Viettel esim and it worked without any problems throughout Vietnam.
Quick activation and good price. Unfortunately, frequent disconnects from network.
I used it only for a few days, but it worked without any issues. The signal was consistently available, and I was able to use Personal Hotspot to share data with my laptop, which was really convenient. However, the price is definitely not on the cheap side. Without the promo code discount, it wouldn't have been my first choice.
Used Jetpac eSIM for my trip to Bali because it was pretty good price during a sale.
Although the IP address was from the US, the internet breakout was in Singapore.
I wouldn't say the connection quality was exceptionally good, but it was decent enough without any major inconveniences, so it certainly passed the test.
While in Bali, it connected to Tri (3) network, and the signal was generally fine. If the price is more or less the same or cheaper, I might consider using it again for my next trip.
Bought their 10GB plan for Malaysia. It worked way better than my expectation in Kuala Lumpur. The speeds were sufficient and the latency was around 40ms.
At least in cities, this seems to be one of the best options in terms of both price and performance.
Worked flawlessly, you just have to use the qr code from the email to set it up, the automatic app activation did not work (android). Their support on whatsapp was also fast and helpful
I bought an Airhub eSim through this site, the payment was done immediately and I got a receipt to my mail but they didn't send me the eSIM details nor the QR code and said that I need to pay for the sim. After many emails still didn't get the esim. DON'T BUY AIRHUB ESIM.
Its a scam.
Bought their 50GB 10 Days eSIM package, and it worked great in Bangkok. Low latency, high speed on dtac 5G. Tethering supported.
Also, eSIMX is one of the easiest to buy eSIMs from. No account needed.
Mobile internet worked fine with the dtac network, mostly on 5G in Phuket. But unfortunately, tethering stopped working after two days. Also, the SMS I received after inquiring about my data usage was unclear about how much data I had left. It simply mentioned “max internet speed” without specifying the 50GB limit or my current usage.
I bought similar dtac eSIM products from other providers in my past trips and tethering worked just fine with them.
Sim Card worked fine initially, however after a few days, the sim stopped working. Airhub provided replacements that lasted again a few days
We went on a round-trip in Bali. Installation of the eSim was easy and network coverage and speed were excellent everywhere
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.
Attention, a payment gateway fee will be charged in addition to the displayed price, but the amount will not be displayed anywhere when paying by credit card! This is illegal, it is not allowed to charge more than indicated and you can therefore request a charge back from the credit card company. In my case, the surcharge was 38%! The app is also terrible, you can't see how much data volume is left. Avoid this dubious company!
Charging more than what displayed, sim is working fine , but doing fraudulent activities
I bought their Asia 5 Countries eSIM to use in Singapore but had problems activating it. The eSIM installed and connected to the network but wouldn't activate and provide data. I wasn't able to get any support as there's only a chat bot. Having to pursue a refund through PayPal.
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.
I used Jetpac’s eSIM while traveling in Thailand, and it worked better than I expected. In Bangkok, it connected to TRUE-H 5G most of the time, occasionally dropping to 4G, but coverage was solid throughout the city. When I headed up to Udon Thani province, it automatically switched to AIS.
Speeds were great, especially download speeds over 100 Mbps. Roaming via Singapore with about 40ms latency, which is quite decent for travel eSIMs. Overall, I’m pretty satisfied with the experience.
Would've been even better if it came with a local number for calls and sms.
It's likely the best travel eSIM available in Laos as of this writing. This Unitel-provided local eSIM comes with a Laos phone number (+856), allowing you to receive calls and SMS (though sending is not available). No eKYC needed.
The speeds are satisfactory, with some 5G coverage in Vientiane, and latency is fantastic as it's not a roaming product. Tethering is supported as well. Coverage in Vientiane area was good, but be sure to do your own research if you plan to travel to the countryside. Overall, it's definitely a good value for money.
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.
The setup was fast and smooth and the eSIM worked from the moment I landed in Fiji.
The issue I have is that it was constantly limited to 3G speeds. Even then, although the cellular signal was at full strength, web pages would take aaaaaaages to load or sometimes not load at all.
I reached out to their support team, but it seems the service is limited because it is an eSIM. My mother purchased a physical SIM card from the same local telco that I was using (Digicel) and she got a much better deal (165GBs) with fast LTE speeds at about the same price that I paid for 5GB at 3G speeds.
I understand that the infrastructure here is limited and eSIMs might be a newer technology that needs time to be developed; but I would have appreciated a heads-up when I was purchasing the eSIM so I would’ve at least known I’d only get 3G speeds.
My two cents - if you can wait to buy an eSIM at the airport when you land, please do. They have much better data bundles for tourists.
SIM simply did not work in Singapore and support was non existent!!
tried to get me to use their portal which wanted me to accept cookies without information on them, a real no no.
SIM supplied for UK was not as advertised connected to EE not O2.
Will not be using them again!
Just bought esim. It installed successfully, but the is “no service” tag. Support for not answering, pulling me constant automatic texts in WhatsApp.
I noticed in the Airalo app that traffic I just bought aka “my package” is “not active”. There is explanations or guide on how to “activate” the paid and installed esim.
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.
So far all the esims I've got with mobimatter worked flawless, in Taiwan I had to adjust the connection network manually once, but it was a minor issue.
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.
