Cellular connectivity on your terms. Seneca's multi-network SIMs give you granular, self-serve control over mobile data — steering automatically across the UK's mobile networks (Vodafone, EE, O2 and Three), with network slicing for isolated private virtual networks and secure routing, including IPSec tunnels back to your own core, plus low-latency breakout across global edge points of presence.

For enterprises, IoT fleets and private-network operators, Seneca's SIMs mean connectivity you configure and control from a single portal: steer traffic, enforce routing policies, whitelist by DNS and keep data off the public internet — without carrier lock-in or heavy capex.
