Networks and technologies are what each provider states; the technology is a ceiling, not a measured speed.

## Internet breakout and latency

Latency is modelled from the distance between the destination and the plan's internet breakout country, not measured, and is shown as a band. Each provider is shown with the breakout country most of its single-breakout plans here use. Typical latency to services inside South Korea: ~70–110 ms.

| Provider | Breaks out in | Latency to local services |
| --- | --- | --- |
| eSIMnow | Hong Kong (~2100 km away) | ~40–60 ms |
| Bloomy eSIM | Singapore (~4700 km away) | ~70–110 ms |
| RedEx eSIM | Singapore (~4700 km away) | ~70–110 ms |
| Roamix | Singapore (~4700 km away) | ~70–110 ms |
| AbestESIM | Singapore (~4700 km away) | ~70–110 ms |
