“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.”
“Connectivity and speeds were spotty in Osaka and Kyoto. eSIM did NOT support hotspot sharing. Would not buy an eSIM from this provider again.”
“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.”
Billion Connect sells unlimited‑data eSIMs for Japan. The Japan eSIM [Unlimited] 1 Day plan gives users unlimited data for a single day. Prices for this plan range from about $11.60 USD up to $68.44 USD, and the network is 5G. The plan notes that speed may be throttled after heavy usage, so normal speed can be reduced under the Fair‑Usage Policy. Travelers who want more detail on how long data will remain at full speed or how much data is available before throttling should contact Billion Connect directly.
Billion Connect does not provide a Japan eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for Japan. Travelers can still send and receive voice or text via popular VoIP applications such as WhatsApp, Telegram, or iMessage that operate over the data connection.
Billion Connect lists 40 single‑country data plans and 45 multi‑country plans available for Japan. The catalogue includes both daily‑data‑cap plans—where the amount of data you can use each day is limited—and fixed‑data‑cap plans, which provide a set amount of data for the entire validity period. Prices span from about $1.32 to $175.00 USD, while data caps range from 1 GB to unlimited, depending on the specific plan chosen.
