“I've used Truely unlimited data in UK, Serbia, Thailand, Turkey and KSA during my backpacking trip. The unlimited data was genuinely nice considering I had to work while traveling. I had issue with the KSA plan once but was fixed pretty fast. The rest of the destination was all good.”
“Bought Stellar Security's Thailand 20GB/30-day eSIM. It installed but never connected or gave me data. I tried different locations, manual network selection and a restart. On 27 August, support confirmed in writing that the eSIM had not started a data session. They said my refund request was referred for review, but never sent the decision. When I followed up, I got repeated copy-paste refusals saying the QR code was delivered, with examples of an eSIM not installed or the wrong destination. Neither applies to me. I asked for a technical review and got the same template again, with no session-log evidence. EUR 5.59 isn't a lot, but I paid for data I couldn't use and still have no refund.”
“Do not use them. They charge you extra fees (€1.49) you never agree to pay and sign you up for a subscription you never agreed to buy. They claim it’s a travel insurance. When you contact them the don’t refund you. Scammers”
“Found the cheapest 50GB plan. Ordered and I've got no confirmation, no information within my account on their page, nothing. WhatsApp support very quick and responsive, though can't help much. Since I've got no plan nor any information, they've said 'will forward to shift manager' couple of times. I had to push them multiple times to receive my Esim. Zero empathy, zero apologies, nothing offered as the apology. Esim arrived 3 HOURS LATE manually into the WhatsApp without any confirmation or whatever, just 'that's your esim'. DO NOT RECOMMEND. Though Esim plan so far working fine, but everything around ain't worth trying to save. BIG REGRET.”
“Didn't work!”
“I noticed that the pay-as-you-go option does not appear in the plan listings on esimdb, which caught my attention a little. After actually using it, I personally feel this is the most convenient option.
Because it is fully usage based, you can keep using it seamlessly even when moving between countries, which is incredibly convenient. With cheaper flight tickets, long layovers at airports in China are common, and sometimes you may want to head into the city for a short while. In those situations, it feels a bit wasteful to purchase a one day plan or a large data package, so this option fits perfectly.
Airport WiFi is available, of course, but connections can be unstable, and SMS verification is sometimes required, which often makes it more troublesome than expected. That is why having the reassurance of being able to connect immediately on your own mobile line, even during immigration, feels very valuable.
Overseas roaming is also available with ahamo and Rakuten Mobile, but there are still countries that are not covered. Having this set up as a dual SIM feels like something that could really help in an emergency. I also appreciate that LINE and WhatsApp continue to work even after the main data allowance has been used up. It is a small detail, but genuinely useful.”
“Able to activate this eSIM from Indonesia however unable to connect to any provider in Singapore. Refund process was quite easy. I gave two stars because of how easy the refund process was otherwise one star.”
“Good”
“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.”
“Overall it was a pleasant experience. Purchase and setup was quick and easy. Will use again if needing a short term Esim for travel.”
“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.”
“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”
“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.”
“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.”
“Connection quality was not specified. It's changing between 3g and LTE. Registration process is a bit clumsy and you don't get your esim instantly.”
“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.”
“Promo code is not working ”
“It is not working, I don’t recommend to use that eSIM ! ”
“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.
”
“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.”
