The Peplink B One keeps your office or branch online through the kind of outage that would knock a single-WAN router offline. It bonds wired internet, cellular (LTE or 5G), and Starlink into one resilient connection, so a dropped link never means a dropped network. For a retail store, a remote office, or a small branch, that means staff stay productive and operations keep running even when one provider has a bad day.

It pairs especially well with Starlink. Connect a dish to any WAN port and the B One balances it against fiber, cable, or cellular, and WAN Smoothing rides over Starlink's brief satellite handover gaps so video calls and VoIP do not stutter. Everything is managed centrally through InControl 2, Peplink's cloud platform, with no on-site visit required.

The B One comes in three variants: the wired-and-Wi-Fi B One, the LTE B One Plus, and the 5G B One 5G. If you need dual-modem cellular bonding or FlexModule expansion, look at the MAX BR2 or Balance 20X instead. The B One is built for simple, affordable branch resilience.

• Multi-WAN connectivity: 2x Gigabit WAN, Wi-Fi as WAN, and USB-C as WAN for maximum flexibility.
• Wi-Fi 6 (802.11ax): dual-band 2x2 MIMO for faster speeds and better coverage.
• SpeedFusion WAN bonding and hot failover: seamless failover and bonded connections for maximum uptime.
• Dual SIM slots: automatic carrier failover for cellular backup.
• 1 Gbps routing throughput: high-speed performance for routing across multiple connections.
• InControl 2 cloud management: easy cloud-based management and remote monitoring.
• Built-in eSIM: flexible carrier connectivity and zero-touch setup on the B One Plus and B One 5G.

The B One Plus and B One 5G are certified for use on AT&T, T-Mobile, Verizon, and FirstNet. Both use Nano-SIM (4FF) plus Peplink eSIM plus BYO eSIM (2 profiles).

The B One 5G additionally supports 5G NR Sub-6 GHz bands n1, n2, n3, n5, n7, n8, n12, n13, n14, n18, n20, n25, n26, n28, n29, n30, n38, n40, n41, n48, n66, n70, n71, n75, n76, n77, n78, n79, plus LTE Cat-20 fallback at 1.6 Gbps downlink.

Does the B One work as a primary router or only as backup?
Both. The B One can run either cellular or wired WAN as your primary connection, with the other as backup, or you can bond them together for higher throughput. Most branch deployments use fiber or cable as the primary connection with cellular as automatic failover.

Can both SIM slots be active at the same time?
No. The B One Plus and B One 5G have a single modem with two SIM slots. You can load two SIM cards for automatic failover between carriers, but only one is active at a time. For dual-modem bonding, look at the MAX BR2 or HD series.

Is the B One compatible with Starlink?
Yes. You can connect Starlink to any WAN port and the B One will manage it like any other WAN connection. You can also load balance Starlink with a second connection, bond multiple Starlink dishes, and apply WAN Smoothing to smooth out interruptions.

Is the B One 5G ready for Private 5G?
Yes. SA mode support means the 5G modem works on enterprise Private 5G networks, plug-and-play with carrier Private 5G offerings.

What is the difference between the B One and the Balance 20X?
The Balance 20X offers more advanced SD-WAN features, FlexModule expansion, and more LAN ports, which makes it a better fit for larger businesses that need more routing capacity. The B One is optimized for simplicity and value: easy setup, more affordable pricing, and branch-level flexibility.
