“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 offer unlimited‑data eSIM plans for South Korea. The company sells a range of unlimited packages, from a single‑day plan priced at $2.86 USD to a 30‑day plan costing $61.00 USD. Validity periods available are 1, 3, 5, 7, 10, 15, 20 and 30 days. All of these packages allow tethering and state that speeds may be throttled after a certain amount of use, reflecting the Fair Usage Policy. Users who are concerned about possible speed restrictions should contact Billion Connect directly to confirm the specific data allowance that can be used at normal speeds before any throttling occurs.
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.
For South Korea, Billion Connect offers 51 single‑country data plans and 59 multi‑country data plans. The plans cover a price range from about $1.21 to $175.00, providing data amounts from 500 MB up to unlimited. Validity periods span 1 to 30 days. In addition, 42 of the plans have a daily data cap—that is, the allotted data resets each day—while 68 plans use a fixed data cap that applies for the entire validity period. This variety allows travelers to choose a plan that best fits their usage pattern and budget.
