Wi-Fi 6 dual-WAN branch router with embedded LTE backupThe Peplink B One Plus is the cellular-equipped sibling of the B One. Same Wi-Fi 6, same SpeedFusion engine, same enterprise-grade firewall, with one critical addition: a built-in CAT-4 LTE modem and redundant SIM slot. When your fixed lines drop, the LTE modem takes over instantly. When they're up, it sits ready as a third path for SpeedFusion bonding or a low-bandwidth management channel. For sites where downtime costs real money, this is the small router that earns its keep.Built for branches that can't afford to dropThe B One Plus targets the 1-150 user environment: retail floors, branch offices, small clinics, remote teams. Two Gigabit Ethernet WAN ports take fixed lines (fibre, FTTC, cable, leased line, or Starlink). A USB-C WAN port adds tethering or a fourth WAN. Embedded LTE adds a fully managed cellular failover with a SIM tray that supports physical SIMs, eSIM provisioning, and Peplink's RemoteSIM via SIM Injector for centralised cellular fleet management. If the primary line dies at 9:42am during a checkout queue, no one notices.SpeedFusion gives you VPN bonding across all WAN paths with hot failover, WAN smoothing, and bandwidth aggregation. Two SpeedFusion peers ship by default, scaling to 5, 10 or 20 with the bundled PrimeCare subscription. The same hardware drives a built-in AP controller for up to 50 access points, so a single B One Plus can run a small site's whole connectivity and Wi-Fi without a separate controller.Specifications Feature Specification Router throughput 1 Gbps SpeedFusion VPN throughput 400 Mbps unencrypted, 200 Mbps with 256-bit AES Recommended users 1 - 150 Wired WAN 2 x Gigabit Ethernet, 1 x USB-C Wired LAN 4 x Gigabit Ethernet Cellular 1 x embedded CAT-4 LTE (downlink up to 150 Mbps, uplink up to 50 Mbps); APAC and EMEA bands B1, B3, B5, B7, B8, B20, B28, B38, B40, B41 SIM Mini-SIM (2FF), redundant SIM slot, eSIM support, BYO eSIM (firmware 8.4+), RemoteSIM via SIM Injector, FusionSIM Wi-Fi Wi-Fi 6, simultaneous 2.4 GHz / 5 GHz, 2x2 MU-MIMO, Wi-Fi as WAN or AP SpeedFusion peers 2 default, up to 20 with PrimeCare AP controller Built-in, up to 30 APs (50 with PrimeCare) Antenna connectors 2 x SMA cellular, 2 x RP-SMA Wi-Fi Power 10-30V DC; 6 W nominal, 17 W max Dimensions 262 x 161 x 33 mm, 760 g Certifications FCC, CE, RoHS Warranty 1-year limited (PrimeCare extends to 4 years) Where it fitsThe B One Plus is the right answer for sites where the cost of an outage is bigger than the cost of a SIM. Retail tills running cloud POS, dental practices syncing imaging to cloud PACS, small accountancy firms with cloud finance, branch offices on Microsoft 365, holiday let receptions on a Starlink primary line. Anywhere a single-WAN router would have you fielding panic calls during the next ISP wobble. We deploy these in pairs across multi-site retail estates and they run for years without intervention thanks to InControl 2 cloud management.What's in the box 1 x Peplink B One Plus router 2 x cellular antennas (SMA) 2 x dual-band Wi-Fi antennas (RP-SMA) 1 x 12V power adapter Quick start guide FAQWill it work with Starlink? Yes. Plug Starlink into one of the Ethernet WAN ports and the B One Plus will treat it as a normal WAN. SpeedFusion can then bond Starlink with the embedded LTE for seamless failover.Can I bring my own SIM? Yes. The Mini-SIM (2FF) tray accepts any unlocked carrier SIM. With firmware 8.4 or above the device also supports BYO eSIM with two profiles. We recommend a multi-network IoT SIM for branch failover.What's the difference between B One, B One Plus and B One 5G? All three share the same Wi-Fi 6 enclosure and 1 Gbps routing engine. The B One has fixed-line WAN only. The B One Plus adds an embedded CAT-4 LTE modem. The B One 5G adds a 5G modem. Step up only when you need the cellular path.Does PrimeCare cost extra? A 1-year PrimeCare subscription is included with every B One Plus we ship. PrimeCare unlocks 5 SpeedFusion peers, InControl 2 cloud management, hot failover, WAN smoothing, bandwidth bonding, and warranty extension. Renewals available as 1, 2, or 4-year extensions.Can I deploy without a public IP on the WAN? Yes. SpeedFusion VPN works through carrier-grade NAT on cellular and through any consumer ISP path with a private IP, because the tunnel is initiated outbound to a hub or peer.Peplink Platinum Partner supportThe Tech Factory ships the B One Plus globally from our supply chain. Free UK delivery over £500. International orders welcomed. Every device includes 1-year PrimeCare. Talk to our engineering team if you need help sizing a SpeedFusion deployment, picking SIMs, or planning a multi-site rollout. We've installed Peplink in production environments since 2015 and we know what works and what does not. Same-day UK dispatch on orders before 13:00 (working days) when the SKU is in our supply chain. Otherwise typically 1 to 3 working days from UK, or 5 to 10 days sourced from EU or US.Router-side SpeedFusion throughput: up to 400 Mbps unencrypted, 200 Mbps with 256-bit AES.
