See what travelers are saying about their East Asia eSIM experience. Real feedback from real users to help you pick the best plan for your trip.
“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 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.”
“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.”
“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 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.”
“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.”
“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.”
“reasonable prices, good connection. never lost connection before expiry date & time.”
“Everything went very comfortable. eSIM was added to phone and the internet started working immediately. A huge plus is that all international services work without a VPN.”
“Bought unlimited 5g from billionconnect. I was reaching to support every 20 minutes to reset my network.Turns out the unlimited is just 1gb.You can't find this detail anywhere... And you can't get your money back.Very dissapointed.”
“I buy and use eSIM all the time and this was the WORST vendor/eSIM service. eSIM did not even work from the start, and no response from the vendor. eSIMDB should delist this vendor from the website.”
“It's a little annoying having to submit passport for authentication but speed and latency is good. Also customer service is easy to reach by Whatsapp and really responsive and knowledgeable.”
“Doesn't have a local internet breakout like it says in the page, it uses Hong Kong operator and the lag is as bad as with the other sims that are 1/6 the price, so save your money”
“Avoid. In order to buy their product (the link through eSIMDB is invalid) you must register (to buy) through either thru 1) phone number 2) Google (social sign-on) or Apple.
Their rates are extremely low and basically too good to be true. I wasn't able to reach support. Avoid.”
“The first time I used an international eSIM from this website with this company, I had no problems at all. I generally got 5G, and I was even in small towns in Japan—I honestly didn’t expect it to work that well.
I highly recommend it. To avoid any issues, and since it was 20GB, I disabled several apps so they wouldn’t use data in the background. By the way, I was also sharing it with my wife.
Everything was perfect.”
“I used the Global eSIM 1GB with a coupon for use within Japan.
It worked very smoothly.
When I went to Hakone where the signal tends to be weak, it stayed connected by switching between SoftBank and KDDI depending on the location.
I think it’s good to keep one as a backup in case of network outages.
The IP address will be from overseas so be careful with Japan-only services.”
“I tried ordering the FREE plan and set it up on my iPhone SE2.
At first, the eSIM activation stayed in “processing on the server” status for about 10 minutes without any response, so I just left it for a while until it finally completed.
After that, the phone stayed out of service and couldn’t connect to the network for over an hour. I had almost given up, but eventually, it just started working on its own.
In terms of speed, there were no issues.
While using the service, I kept checking the data usage on the website, but after reaching 0.01GB, the connection stopped working completely. I thought maybe the usage display was just delayed, but even the next day, it hadn’t updated. It felt like I had used more data than what was shown, so the website’s usage display doesn’t seem very reliable.”
“Connectivity and speeds were spotty in Osaka and Kyoto. eSIM did NOT support hotspot sharing. Would not buy an eSIM from this provider again.”
“This was my first time downloading an e-SIM. I used an iPhone 15 and everything was very simple. I didn't use the calls, just the data plan, 5GB for 10 days in Australia for $6, and it worked great. The price was very reasonable, and although I didn't check the remaining data, I can say that it was enough for me.”
“Throttled to 12 mbps. Otherwise perfect connection and excellent price.”
“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.”
