Delays, Misleading Product Info, and a Frustrating Refund Process

I bought two 33GB eSIMs for the Philippines and they were completely unusable — SMART required local‑resident documents, which Airhub never mentioned. Support ignored my ticket for 17 days, then claimed they had replied (they hadn’t) and even leaked another customer’s email in a screenshot.
After weeks of excuses and delays, they only offered a 50% refund for a service that never worked at all.
Unreliable service, misleading info, and very poor support.

Avoid by any means. Very bad user experience. eSIMs stop work in a random time before data or days exceeded (for example on 13 day of 30 days plan), no refund from company.

I used Jetpac eSIM in Bali. It worked perfectly, but outside of Bali, the network speed decreased significantly. Otherwise, the experience was smooth. If you plan your trip outside of Bali for most of the time, then you should consider something else.

3rd class experience. The calling option never worked. Reached out to customer care and they had no idea about the plan purchased here. Save your money and buy something else.

ChillaxSIM

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!

I bought unlimited for one day. Throttling speed was so obvious, can't go above 200 kb/s. Regardless of advertising 5g, esim connected on LTE network.
Complete waste of money.

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.

Billion Connect

Jamesused in Japan 🇯🇵, China 🇨🇳, Philippines 🇵🇭, South Korea 🇰🇷

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.

Kaguused in Singapore 🇸🇬

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.

Yoho Mobile

Jamesused in Philippines 🇵🇭

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

clarameused in Singapore 🇸🇬

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

Airalo

skused in Cambodia 🇰🇭

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.

Roamify

Anjiused in Thailand 🇹🇭, Indonesia 🇮🇩, Malaysia 🇲🇾

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.

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 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.

ghostmosefused in Indonesia 🇮🇩

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.

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.

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!
