Cellular Bonding vs Load Balancing: What Is the Difference?

A load balancing router spreads separate sessions across several connections, but each session, such as a video call, still runs over just one of them. Bonding splits every session across all the connections and reassembles it at a server, so a single stream gets the combined bandwidth and survives one link dropping. Load balancing needs no server; bonding does.

01

The Short Answer

Load balancing works well for many users browsing at once, because their sessions are shared out across the links. It falls short for anything that needs one fast, steady connection, such as streaming or video conferencing, because that session is at the mercy of whichever single SIM it lands on.

    Many light users Load balancing is simpler and needs no server.
  • //
    Streaming and video calls Bonding keeps a single session fast and stable.
  • //
    Moving platforms Bonding rides through the signal changes on vessels and vehicles.
  • //
    Failover only A dual-SIM router with failover may be enough.
