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 connectivity is so-so. Network carrier is SoftBank and it reconnects from time to time. Not very satisfied with the stability and channeling through HK. But it’s cheap price.

Pretty poor experience. 5G promised but actually 4G only. Talked to their customer service. Guess what? They say it varies by area and operator

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.

Not that fast but okay-ish speeds in Japan on the KDDI (au) network. However, the biggest drawback is that this eSIM routes through Hong Kong (HK IP address), so ChatGPT doesn’t work which is a real shame.

Eskimo eSIM

htkused in Japan 🇯🇵

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.

S.Hused in Japan 🇯🇵

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.

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.

Do not buy the Clearance esim. It's not mentioned on the website, but it's routed through Hong Kong. The connection is very bad and 5G seems capped at slow speeds. I had issues keeping a consistent connection and ended up buying a MobiMatter esim that has worked flawlessly.

The product claimed to support multiple carriers, so I decided to try out the "eSIM, 3GB, 30 Days, Japan" for use in Japan.
It seems the APN "vmobile.jp" (iij) can be used, but... is this really multi-carrier?

Giga.Tel

iTravelalotyesindeedused in South Korea 🇰🇷

Beware: 1) No call/text available in South Korea. 2) Routed via HK so not the best service due to latency, but the same as most competitors in SK for eSIM. 3) Weird discrepancy on their website about price in USD vs charged amount ($1.00 USD more is charged than shown online). How do I know? I bought 3 eSIMs from Giga.Tel in South Korea, and over 10 from eSIM competitors. So far they are still the cheapest for the same 30GB and quality of service. Plus you can checkout with American Express in case of a dispute (MobiMatter does not allow Amex)

Pamused in Japan 🇯🇵

Used without issues in both Tokyo and Osaka. The latency wasn't great due to roaming connection through Singapore, but was manageable. At least it’s more convenient than eSIMs that go through Hong Kong and don’t work with services like ChatGPT. The network was au’s LTE or 5G, and signal was solid everywhere, no complaints.

I went with this esim because of the great value and because I saw a positive review (after having tried a couple esims in the past with various companies that barely worked, I'm always a bit apprehensive to try one without and positive reviews) and I just wanted to second that review - airlink worked perfectly throughout Korea (have been connected to SK network the whole 3 weeks) and when considering price per GB, I doubt there are many better options.

The internet worked perfectly everywhere – airports , even on road trips. No annoying "loading..." screens! Plus their customer chat is LEGIT. Messaged them at 1AM (jetlag lol) and replied in 2 minutes. She literally stayed on chat while I set it up, double-checked everything. Way cheaper than my phone plan back home. Never going back to regular SIM cards!

coverage was very good, easy setup at public wifi spot upon arrival. One major thing though: internet breakout is Hong Kong.

There is no instagram coverage (anymore) in Hong Kong!

If you plan to use this operator, you should be aware of this.

Sim does not work for data in Korea. They also claim 24/7 support but they haven’t been online for the last 6 hours. Avoid company, I was left without any internet access when I landed and had to scramble poor free wifi to buy a different eSIM.

They still have not refunded me going to have to file a charge back. Avoid at all costs

BNESIM

DSused in Japan 🇯🇵

Doesn't work! Waste of money! I was only able to see if it works after arriving in Japan in March '25, but I never got connected when automatic carrier selection is on. I chatted with the BNESIM support and was told to select KDDI manually. After that I was able to get connected, for no more than 2 mins each time in a series of unsuccessful attempts. I then chatted with the support again. This time they said this case will be escalated to the advanced team and I'd be hearing from them within 24 hrs. Yes, you're right! The never responded to me afterwards! Sadly speaking, this is the second time I run into the same situation with them. I bought another esim in 10 mins from EIOTCLUB and I got continuous, stable connection ever since. So which one is the scam?

Installation was easy, price was okay. Coverage and speed were good.

However, the website said it would connect to all networks (docomo, KDDI, SoftBank, Rakuten) but only KDDI worked for me.

The usage display only updated every 5 days (not ideal). Top-up was not possible.

Overall an okay experience.
