What device do I need for internet backup?

You need two things: a backup internet connection (cellular SIM card or second ISP) and a dual WAN router that monitors both connections and switches automatically when the primary fails. The most convenient option is an all-in-one LTE router like the Peplink Balance 20X, which includes a built-in cellular modem slot — you insert a SIM card and the device handles both routing and cellular backup. If you already have a compatible primary router, a standalone LTE modem ($80–$200) can serve as the backup WAN source.

Can I use a hotspot as a backup internet device?

A mobile hotspot (like the Netgear Nighthawk M6 Pro or a carrier hotspot) can function as a backup internet source, but it requires an additional dual WAN router to provide automatic failover. Without a dual WAN router, the hotspot just creates a separate Wi-Fi network — staff would have to manually switch devices when the primary goes down. For true automatic failover, the hotspot connects to the WAN 2 port of a dual WAN router.

What is the difference between a backup modem and a backup router?

A backup modem (cellular LTE modem) provides the secondary internet connection — it has the SIM card and connects to the cellular network. A backup router (dual WAN router) manages the automatic switching between primary and backup connections. You need both. The simplest setup combines them: an all-in-one router like the Peplink Balance 20X has both a WAN port for the primary connection and a built-in LTE modem slot for the backup, so one device does everything.

Internet Backup Device Guide: Best Routers & Modems for Business Failover

About this guide: Device pricing from Amazon, 5Gstore.com, and authorized Peplink/Cradlepoint resellers Q1 2026. Covers US market. Prices vary — verify before purchasing. All devices mentioned support major US carriers (Verizon, T-Mobile, AT&T) unless noted.

There are four categories of internet backup devices, and they solve the backup problem in fundamentally different ways. Choosing the wrong category is the most common device mistake — particularly buying a consumer hotspot and assuming it provides automatic failover (it doesn't, without a dual WAN router in front of it).

The core functional requirement is the same regardless of category: the backup device must be always connected to the backup network, actively monitored by a router, and capable of becoming the active WAN connection in under 60 seconds without staff intervention. How each device category achieves that — and at what cost and complexity — is what differentiates them.

The four categories of internet backup devices

All-in-one LTE router

Standalone LTE modem

Add-on to existing router

Price:$80–$380

Router:Separate required

WAN out:Ethernet

A cellular modem that provides an Ethernet WAN output, plugged into the WAN 2 port of your existing dual WAN-capable router. Works with any router that has a second WAN port and health-check failover (UniFi, Peplink, pfSense, Meraki).

✓ Lower cost; works with existing router

⚠ Your existing router must support dual WAN failover

Managed failover appliance

No IT staff needed

Price:$0–$200/mo all-in

Data plan:Included

Config:Provider-managed

Hardware and data plan bundled from a managed service provider (Verizon Business Backup, RocketFailover, Cradlepoint with NetCloud). Provider pre-configures the device, monitors it remotely, and handles all failover logic. Plug it in and it works.

✓ Zero configuration; includes support

⚠ Higher ongoing cost than self-managed

Carrier-provided gateway

Lowest upfront cost

Price:$0 with plan

Failover:Manual config

Lock-in:Carrier-tied

Free gateway from Verizon, T-Mobile, or AT&T with plan activation. Designed primarily for primary use. Can be used as a backup WAN source by connecting its Ethernet output to a dual WAN router's WAN 2 port. Limited configuration options compared to purpose-built backup devices.

✓ No hardware cost; available immediately

⚠ Limited failover config; carrier-locked device

Which device for which business size

1–10 employees

Peplink MAX BR1 Mini ($230) + Verizon 5GB backup plan ($35/mo). Built-in LTE handles basic office failover. Fast setup with no technical background needed. SpeedFusion basic keeps VoIP stable during outage switches.

10–60 employees

Peplink Balance 20X ($400) + business LTE plan ($50–$85/mo). The sweet spot for most small and mid-size businesses — handles up to 60 users, built-in LTE modem, InControl2 cloud management free for basic monitoring.

60–100 employees

Peplink MAX BR1 Pro 5G ($950) or Cradlepoint E300 ($600 + NetCloud). Dual SIM for two-carrier redundancy. 5G throughput headroom for high-bandwidth sustained use during primary outages. SpeedFusion hot failover for VoIP-critical environments.

No IT staff

Verizon Business Backup managed plan + carrier gateway ($35–$50/mo, hardware free). Provider handles configuration and monitoring. Call Verizon Business and they ship a pre-configured Cradlepoint gateway — plug into your primary router's WAN 2 and it works.

Multi-location (5+ sites)

Cradlepoint E-series with NetCloud ($500–$700 + $50/mo/site). Centralized management, zero-touch provisioning, fleet monitoring across all sites. Per-site subscription adds up but eliminates on-site configuration for each location.

Peplink vs. Cradlepoint — the only comparison that matters for SMBs

Both platforms support the same core use case: LTE/5G failover with automatic switching. The meaningful differences are in management model and cost structure.

Peplink sells hardware with an optional PrimeCare subscription (~$149/year per device) for cloud management via InControl2. Hardware works without the subscription — basic failover functions locally without any cloud dependency. This makes Peplink the better choice for businesses that want simplicity and want to own their hardware outright. SpeedFusion is Peplink's differentiating technology for hot failover and WAN bonding.

Cradlepoint (now Ericsson Cradlepoint) sells hardware exclusively as a bundle with its NetCloud management subscription. You cannot operate a Cradlepoint device without the subscription — it's a mandatory ongoing cost. NetCloud is genuinely excellent for multi-site management, FedRAMP-authorized for government deployments, and more powerful than InControl2 for large enterprise policy management. For a single-location small business, the mandatory subscription cost adds $40–$80/month above hardware amortization. For IT teams managing 50+ sites, it earns its cost.

The external antenna upgrade most people skip

Every all-in-one LTE router's built-in antennas perform adequately in areas with strong carrier signal. In fringe-coverage areas — suburban edges, ground-floor offices in dense urban buildings, metal-construction commercial spaces — adding an external directional MIMO antenna ($40–$120) connected to the router's SMA antenna ports can improve signal 15–25 dB. This often converts an unreliable backup connection into a fully functional one. Check your router's specs for SMA connector compatibility before purchasing an external antenna.
