Best Bonding for streaming

Combines multiple links into one resilient stream. eSIM only fails over, it does not bond.

Which bonding should you use for streaming?
StreamPartPicker tracks 4 bonding options for streaming, ordered by what each costs to run for a year: anything you buy once plus twelve months of subscription. belaBOX SRTLA is the cheapest to run at Free (with belaBOX), Peplink + SpeedFusion the most at $400 + $13/mo. Options with no fixed price, free software and pay-per-GB data, sit first. Nothing here has a retailer rating to rank on, so cost and the specs below are the comparison, and none of it is lab-tested by us.
eSIM Is Failover, Not Bonding

Adding a second SIM to a phone gives you a backup connection, not a bigger one: a phone uses one data connection at a time, so two carriers only add bandwidth when a bonding device or service actively combines them.
