See what travelers are saying about their Asia eSIM experience. Real feedback from real users to help you pick the best plan for your trip.
“Watch out for FRAUDULENT practices:
When you buy an eSIM, they just add an antivirus subscription to your order! That means: long after you’re done using the eSIM, you’ll still be paying for that antivirus subscription!!
At checkout, they add that subscription which you obviously didn’t want, and even if you notice it and click that “No thanks”-button, they’ll still add it and it will appear on your order.
So, if you never spot that €0.99 charge every week on your credit card bill, you’ll be paying it for years and years…”
“The SIM card works only with “Türk Telekom” and “Vodafone Turkey” networks. During the day, the internet speed was good, around 20 Mb/s, but every day after 6:00 p.m., the speed dropped to 1–2 Mb/s. This was very frustrating, and sometimes web pages wouldn’t even load. In my opinion, this isn’t the fault of the eSIM provider, but rather “Türk Telekom.” The solution to this problem is to manually select “Vodafone Turkey” towers on your phone. On Vodafone towers, the internet works reliably at all times.
You must install the eSIM before arriving in Turkey; otherwise, you won’t be able to do it. Turkey blocks eSIM installation. This applies to every carrier.”
“Unfortunately, the card only connects to “Türk Telekom” transmitters. During the day, the internet speed was good, around 20 Mb/s, but every day after 6:00 p.m., the speed dropped to 1–2 Mb/s. This was very frustrating, and sometimes web pages wouldn’t even load. In my opinion, this isn’t the fault of the eSIM provider, but rather “Türk Telekom.”
You must activate the eSIM before arriving in Turkey; otherwise, you won’t be able to do it. Turkey blocks eSIM activation. This applies to every carrier.”
“Worked flawlessly with great signal. The auto top up feature didn't work, but manual top up went great. Loved the price and will use again!”
“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.”
“DO NOT PURCHASE, THEY WON'T REFUND YOU IF THEIR SERVICE DOESN'T WORK. Didn't work at all. Went round and round with their support with no resolution and no connection. I wasted several hours of my day trying to get it to work. To add insult to injury, they refused to issue a refund for their nonfunctional service, and I've had to pursue a chargeback with my credit card company.”
“Had a great experience with Ozly in Japan. The eSIM had trouble connecting at first but eventually succeeded after some fiddling in the phone settings (the provider's AI chatbot actually gave me a helpful tip). Got a local IP so no geoblocking. Speed was satisfactory and I got signal in every city I visited (Tokyo, Hiroshima, Fukuoka, Sapporo and a few smaller ones) except in one rural area in Chiba-ken. For the price I paid, it was an incredible deal.”
“It worked for a short time and I downloaded about 3 MB of emails. Then I disabled data roaming and renabled it the next day when I didn't have wifi. I could not get it to work again - the phone kept prompting me to set a carrier name. There was no help on their website. I never got it to work so my money was wasted. They send me an email with a link to review the purchase but that did not work. They claim to refund non-function sims if you email them but I have emailed twice with no response. I think this company should not be trusted.”
“It is operated by China Mobile when you use it in Taiwan. It means that you need to submit your passport info and photo in order to get the activation done and get the connection. Or, you paid and activated but you are off line. The quality of connection is not good. For some apps, it fails to connect the internet.”
“This eSİM claims to roam with 2 Turkish networks, which was my reason to buy. This is not true. Like many other travel eSİMs, it connects to Avea/TT only. Turkcell, although mentioned as a roaming partner, does not connect, says "not allowed"
I contacted support, but they behave as if they do not understand. Final recommendation, after a couple of emails, was to just set the phone to automatic selection. Hey!”
“Title: WARNING: 100GB Plan Blocked After 25GB Use – Stay Away
I purchased Airhub's 100GB plan specifically for its advertised data allowance. However, after using only ~25GB in a few days (only 25% of the plan), the service was permanently blocked.
I spent 11 days emailing support, only for them to finally admit:
"Please note that your eSIM has been temporarily suspended due to abnormal data usage within a very short period of time, as detected by the network. This action is taken automatically to prevent unusual or excessive usage."
Selling a 100GB plan and then blocking it for "abnormal usage" at 25GB is deceptive. They have refused to reactivate the line or offer any refund for the 75GB of data I never received. Do not trust their advertised data limits. ”
“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.”
“I purchased an eSIM from Yatelo for India, 5 GB for 30 days. It worked for only one week, I had used up only 0.5 GB of my data and it stopped working. No more Internet all day in different locations.
I wasted about 40 minutes with their online support, they suggested endless things to try, none of them got the eSIM working again. They then refused to refund the money, saying they were escalating to the engineers. ”
“I bought 4 esim for Japan travel. Very bad experience. For the first day, it auto connected to Softbank service, and extremely slow and lost connection from time to time. Checked the usage, it's less than 1GB usage. The customer support was useless. Will not buy it again”
“I do not recommend this site for purchase. Before purchasing, I came across a number of negative reviews, but I decided to try my luck anyway. Here's my experience: In Uzbekistan, everything worked perfectly for one day, but the speed was terrible on the second day. In South Korea, everything worked well, but in China, everything worked well for two days, and then the internet simply disappeared, even though I still had plenty of data and time left. There is no support, and the AI agent responds by saying that I am doing something wrong.”
“Bought 3 of their Hong Kong & Macau 7 day eSIMs and none of them worked on my Google Pixel 9A and Pixel 10 phones, they ended up gave me one replacement eSIM from a different vendor and refunded the other two. My relatives bought 4 of their 7 day Hong Kong only eSIMs around the same time as me and they all worked flawlessly.”
“I bought it for my short trip in Kazakhstan and got great experience due to routing in United Kingdom (most of eSIM providers use Singapore routing that is really slow in Kazakhstan). On LTE I've got 50-100 Mbps download and 50 Mbps upload speed.
So I definitely recommend buying this one for Kazakhstan to get stable connection without issues.”
“Hello, I purchased an unlimited data eSIM from esim.dog for my 5-day Umrah trip to Mecca, and it was a terrible experience from start to finish. Despite the signal being strong, the internet speed never exceeded 200kbps, making it impossible to browse.
I am aware that Saudi Arabia has certain internet restrictions, and I even used a paid VPN service to try and fix the issue. After switching between multiple countries on my VPN, I was barely able to use WhatsApp for texting. Web pages wouldn’t load even after refreshing 2-3 times, and images were non-existent. Without a VPN, I couldn't even access local Saudi flight or train booking sites. This was easily the worst eSIM service I have ever used. Think twice before buying.”
“Bought a 14-day eSim from Yoho. After 5 days, it expired. I uploaded a screenshot as proof. Also, they advertise 24/7 support but that's also not true. Their chat support says "Live Chat" only for show since no one is responding there. There are plenty of cheap eSim available out there. Choose a different company.”
“Used Micro-Esim for the first time, went great.
Bought online, got sent a QR code by email, downloaded it to my android and installed it, had it off as second SIM until landed in China and then turned it on, worked great for the time I was in China.
Could not get Instagram or TikTok to work but that will be due to country rules and not the SIM.”
“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.”
“Pre-installed Nomad eSIM on a 10GB/30day plan. Activation at the Guangzhou airport after a 15 hr flight was bit challenging. I used the combination of Airport Wi-Fi & Firsty Tier 1 Free Basic to bootstrap start Nomad. Provisioning and activatin took less than 5 minutes max. Nomad has implied VPN features, so to really use the cellular connection service provided by partner China Telecom, under Settings I disabled wi-fi in my iPhone 16 and primary SIM. I was able to access 90% of my Apps (normally blocked: YT, FB, WhatsApp, Outlook emails, Gmails, etc.). Some locations even with signals at 4-bars, both eSIMs appeared not working, that is the network connection issues and not the eSIM's fault. Overall very satisfied with Nomad (paid) DL upto 90Mbs and Firsty (free) 230Kbs as backup.”
“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.”
Asia Travel eSIM FAQ
Everything you need to know about using eSIMs in Asia
How many travel eSIM brands (providers) are available for use in Asia, and how many prepaid data plans are there?
There are roughly 180 travel eSIM providers and more than 8 000 prepaid data plans available for use in Asia, giving travelers a broad selection of options to meet their needs. The wide variety of plans makes it easy to find an eSIM that matches any budget or usage requirement.
Are there any unlimited data eSIM plans available for Asia?
Several providers offer unlimited data eSIM plans for use across Asia. Earth Esim, Roamify, esimzon, Truely, Yesim, FairPlay and Bloomy eSIM all list unlimited data options with validity periods ranging from one day to 80 days. Many of the plans allow tethering, though most include speed throttling or specific speed limits—such as 5 Mbps for Earth Esim or 10 Mbps for esimzon. Prices for these unlimited plans span from roughly $3.75 to $344.21 USD, varying based on the chosen duration and provider.
Can I get a travel eSIM with a phone number and SMS for Asia?
Yes. Several providers offer travel eSIMs that include a phone number and SMS capability while covering Asia. Providers such as GlobaleSIM (for example the Far East 1GB/7‑day plan and the 15GB/30‑day plan), EtravelSIM (their Travel eSIM for Asia 4 GB, 10 GB, 25 GB and 50 GB packages), Roamify (Asia Lite, Asia Sprint and Asia eSIM 20 GB plans), and Airhub (Asia 20 GB, 50 GB and 100 GB packages) offer voice inbound/outbound and such SMS features. The phone numbers that these plans deliver use foreign dialing codes – +1 for the GlobaleSIM and Roamify plans, +44 for the EtravelSIM Asia plans and +33 for the Airhub Asia plans – so they are not local Asian numbers. Prices for these Asia‑focused packages generally begin around $4 for the smallest GlobaleSIM offerings, $10.99 for the 4 GB EtravelSIM plan, $35 for the 20 GB Roamify packs, and $32–$74 for the Airhub Asia plans, with validity ranging from 7 days to 30 days.
