Each tier changes how your connections work together. Essential is automatic backup: if your primary connection drops, your 5G kicks in on its own within a few seconds, then hands back when your main line recovers. No action needed from you. Smart uses selective bonding: critical traffic like calls, VPN, and gaming runs across both connections so it never drops, while browsing and downloads run at full speed. Smart+ is Smart with a third modem and a third carrier for the most bandwidth and the most ways to stay online.
Bonding has some overhead, so bonded traffic comes with a speed cap. On both Smart and Smart+ that cap only affects your protected traffic — browsing, streaming, and downloads always run at full speed.
For most people, Smart is the best fit. Smart+ is for sites that want maximum redundancy across multiple carriers. The pricing table above has the full breakdown.
