See what travelers are saying about their Southeast Asia eSIM experience. Real feedback from real users to help you pick the best plan for your trip.
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
Southeast Asia Travel eSIM FAQ
Everything you need to know about using eSIMs in Southeast Asia
How many travel eSIM brands (providers) are available for use in Southeast Asia, and how many prepaid data plans are there?
There are about 160 travel eSIM providers and roughly 7, 500 prepaid data plans available for Southeast Asia. The extensive selection offers a wide variety of options, making it easy for travelers to find an eSIM that suits their needs.
Are there any unlimited data eSIM plans available for Southeast Asia?
Unlimited data eSIM plans are available for travelers heading to Southeast Asia. Providers such as abesteSIM, Roamify, Earth Esim, Truely, Giga.Tel, Yesim, and FairPlay all offer plans with no data cap, though some may throttle speed after a certain volume. Earth Esim specifically limits speed to 5 Mbps, and Giga.Tel caps it at 10 Mbps, while the other plans note potential throttling without a fixed speed limit. Prices for these unlimited options range broadly from as low as $2.55 USD on a one‑day plan with abesteSIM to about $112.62 USD on a 30‑day plan with Yesim. The diversity of validity periods and pricing allows travelers to choose a plan that aligns with the length of stay and expected data usage.
Can I get a travel eSIM with a phone number and SMS for Southeast Asia?
Travel eSIMs that include a phone number and SMS are available for Southeast Asia. Providers such as GlobaleSIM, ESIM.DOG, EtravelSIM, JamboSim, Roamify, and Giga.Tel, along with others, offer plans that give you an inbound/outbound voice line and inbound/outbound SMS. Prices for these plans start around US$4 and typical validity periods range from 7 to 30 days, with some options extending to 60 days.
In most of these plans the phone number uses a foreign dialing code—for example +1 (United States), +44 (United Kingdom), +33 (France), +61 (Australia), +971 (United Arab Emirates), +376 (Andorra), or +7 (Russia)—so the number is not local to Southeast Asia. Only one plan listed in the dataset, offered by RedEx eSIM with dialing code +62, provides a local Indonesian number; all other plans give a non‑local number. Travelers should check which dialing codes are accessible in their destination country if a local number is required.
