The ultimate guide to multi-SIM mobile proxies

A multi-SIM mobile proxy puts several real SIM cards behind one access point. Instead of a single mobile IP, you draw from a small pool of carrier lines — which means a fresh, genuine mobile IP on demand and far more total range to work with.

How multi-SIM rotation works

With a single SIM you get one IP that changes only when the carrier reassigns it or you trigger a rotation. With multi-SIM, each new connection can be routed to a different SIM, so you get a fresh exit IP per session without waiting on the carrier. That's ideal for workflows that need many distinct IPs in a short window.

• Per-connection rotation: each new outbound connection can land on a different SIM.
• On-demand rotation: trigger a fresh IP from your portal or via the rotation API link.
• Sticky sessions: hold one SIM for the length of a task when you need consistency.

When to choose multi-SIM

Multi-SIM shines when you're managing many accounts or running automation that benefits from IP diversity — warming accounts, distributed scraping, or anything where repeating the same IP raises flags. For a single account you babysit long-term, a dedicated single-SIM line with manual rotation is often simpler and cheaper.

Protocol notes

Multi-SIM lines expose HTTP and SOCKS5. A practical detail: rotating IPv6 works cleanly over HTTP (stateless per request), while long-lived SOCKS sessions are best paired with IPv4. Pick your location and platform at checkout and we provision the right configuration automatically.
