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

belaBOX SRTLA
Free (with belaBOX)Bonds several connections to your relay, built into the belaBOX encoder. Free.
- Approach
- Relay bonding
- Combines links
- Yes
- 2
Moblin SRTLA (cellular + Wi-Fi)
Free (app)Moblin can send SRTLA over the iPhone cellular line and a Wi-Fi link at once, which turns a hotspot from a second phone into real bonded uplink.
The catch: Needs a relay that speaks SRTLA (belaBOX Cloud or your own srtla_rec), and iOS decides how much it lets the app use each link.
- Approach
- App bonding (SRTLA)
- Combines links
- Yes (cellular + Wi-Fi)
- 3
IRL Pro SRTLA bonding
Free (app)On Android, IRL Pro bonds the phone line with USB modems or a Wi-Fi hotspot through SRTLA, the same protocol a belaBOX uses.
The catch: Android only, and a phone driving USB modems drains fast, so budget a power bank into the plan.
- Approach
- App bonding (SRTLA)
- Combines links
- Yes (phone + USB modems)
- 4
SRTLA on your own relay (srtla_rec)
Free (plus your VPS)The open-source receiver half of belaBOX bonding. Run srtla_rec next to SLS or MediaMTX on a VPS and any SRTLA sender bonds to it for free.
The catch: You are the sysadmin: Linux, firewall ports, and the 3 a.m. restart are all yours.
- Approach
- Relay bonding (SRTLA)
- Combines links
- Yes
- 5
OpenMPTCProuter (DIY)
Free (plus router + VPS)A router firmware that bonds every WAN it has through a VPS with multipath TCP, so even plain RTMP rides on all your modems at once.
The catch: Serious networking homework, a dedicated router board, and TCP bonding adds latency that SRTLA does not.
- Approach
- Router bonding (MPTCP)
- Combines links
- Yes
- 6
Peplink FusionHub Solo
Free licence (plus VPS)The free single-peer SpeedFusion server licence. Put it on a VPS and a Peplink router in the bag bonds its cellular links to it with no monthly fee for the hub.
The catch: Needs a Peplink router with a SpeedFusion licence, and the VPS is still on you.
- Approach
- Hardware bonding (server side)
- Combines links
- Yes
- 7
GL.iNet multi-WAN failover
Included with routerMost GL.iNet travel routers can hold a cellular link, a USB modem and a phone tether and switch between them. Honest failover for the price of the router you already own.
The catch: It switches, it does not combine: the stream still rides one link at a time, so it does not raise the tier.
- Approach
- Failover / load balance
- Combines links
- No
- 8
TVU ISX bonding
Quote-based, with a TVU unitThe cellular bonding stack in the TVU One, built for news trucks and stadium sidelines. The reference for what "it never drops" costs.
The catch: TVU hardware only, quote-based pricing, and overkill for anything that is not a paid production.
- Approach
- Hardware bonding (broadcast)
- Combines links
- Yes
- 9
Dejero Smart Blending (EnGo)
Quote-based, with a Dejero unitBroadcast bonding that blends cellular, Wi-Fi and satellite in a single EnGo transmitter. What the networks rent for live remotes.
The catch: Rental and enterprise pricing; nobody buys one for a Twitch channel.
- Approach
- Hardware bonding (broadcast)
- Combines links
- Yes
- 10
Haivision PRO / AIR (AVIWEST)
Quote-based, with a Haivision unitThe bonded transmitters formerly sold as AVIWEST, with SST bonding across up to eight cellular links. The LiveU alternative in European broadcast.
The catch: Broadcast pricing and a StreamHub receiver on the other end.
- Approach
- Hardware bonding (broadcast)
- Combines links
- Yes
- 11
Kiloview KiloLink bonding
Free server, with a Kiloview P-seriesKiloview P-series encoders bond their built-in and USB modems through a free KiloLink Server you run yourself or in Kiloview cloud.
The catch: Needs a Kiloview P1, P2 or P3 encoder; the bonding does not exist without their box.
- Approach
- Hardware bonding (encoder)
- Combines links
- Yes
- 12
Teradek Core + Node bonding
Subscription, with Teradek hardwareTeradek encoders bond a Node cellular module and any other link through the Core cloud, which then hands one stream to your platform.
The catch: A Core subscription on top of a Teradek encoder and Node, so it is the pricier of the prosumer bonding routes.
- Approach
- Hardware bonding (cloud)
- Combines links
- Yes
- 13
Mushroom Networks Streamer
Quote-basedA bonding router built specifically for live video: plug cellular modems in, point any encoder at it, and it presents one fat pipe with packet-level reassembly on the far end.
The catch: Enterprise pricing and a hosted counterpart on the other side, aimed at churches and broadcasters more than creators.
- Approach
- Hardware bonding (router)
- Combines links
- Yes
- 14
Bondix S.A.N.E.
Licence, quote-basedSoftware bonding that installs on routers people already own (Teltonika, MikroTik, OpenWrt) and terminates on a Bondix server. The router-agnostic SpeedFusion.
The catch: Licensed per client and per server, so the first quote is where the price is.
- Approach
- Software bonding (router)
- Combines links
- Yes
- 15
Comrex LiveShot
Quote-basedThe radio-industry video codec with cellular bonding, popular with local TV. Lists here because it is what a station engineer will suggest when asked.
The catch: Broadcast pricing and a matching decoder at the studio end.
- Approach
- Hardware bonding (broadcast)
- Combines links
- Yes
- 16
eSIM dual-carrier (failover)
Carrier plans$15/mo$180 first yearRun a backup carrier on the same phone so one dead network does not kill the stream.
The catch: This is failover, not bonding: it switches links, it does not combine them.
- Approach
- Failover
- Combines links
- No
- 17
Speedify
Subscription$15/mo$180 first yearSoftware channel-bonding that fuses cellular and wifi into one resilient pipe.
- Approach
- Software bonding
- Combines links
- Yes
- 18
Speedify on a Linux router
Subscription$15/mo$180 first yearThe same Speedify bonding, run on a Raspberry Pi or Linux box in the bag so a hardware encoder that cannot bond by itself still gets one fused pipe.
The catch: A second computer to power and keep updated, and Speedify is a VPN hop, so the relay sees Speedify servers, not your modems.
- Approach
- Software bonding (router)
- Combines links
- Yes
- 19
Peplink + SpeedFusion
Hardware + subscription$400 + $13/mo$556 first yearHardware dual-SIM bonding router with cloud failover. The pro reliability tier.
The catch: Router cost plus a SpeedFusion subscription.
- Approach
- Hardware bonding
- Combines links
- Yes
- 20
LiveU LRT (Solo / Solo PRO)
Subscription, with a LiveU unit$50/mo$600 first yearThe bonding inside every LiveU: LRT splits the stream across the modems attached to the Solo or Solo PRO and reassembles it in LiveU cloud before it reaches your platform.
The catch: Only works with LiveU hardware, and the bonding service is a recurring line item on top of the box.
- Approach
- Hardware bonding (broadcast)
- Combines links
- Yes
