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 Saint Lucia: ~110–160 ms.
