“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.”
Billion Connect does not provide an unlimited data eSIM for South Korea. The available South Korean plans have fixed data caps. For example, the Orange World eSIM 1 day 100 GB plan costs $65.79 USD, while the South Korea eSIM 30 days 50 GB plan costs $22.64 USD.
Because only fixed‑data plans are offered, travelers who need a very large amount of data may find these options more economical than paying for data on a per‑GB basis. However, if a user requires continuous, truly unlimited data, Billion Connect does not supply such a plan for South Korea.
Billion Connect does not provide eSIM plans for South Korea that include a local phone number or SMS capability. The provider offers only data‑only eSIMs. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the internet connection for voice and messaging, but no built‑in phone number or SMS service is available.
Billion Connect features 39 single‑country data plans that can be used in South Korea alone, and an additional 51 multi‑country plans that include coverage of the country. The available plans span a price range from $1.21 to $175, with data caps that vary from 500 MB up to 100 GB and validity from a single day to thirty days. The plans are divided into fixed data amounts and daily data cap options, allowing travelers to choose either a predetermined data bundle or a flexible daily usage allowance.
