GL-X2000(Spitz Plus) Cellular Gateway 4G LTE Router for Home

The Verdict

If you live somewhere cable and fiber refuse to reach, or you bounce between an RV and your home office, the GL-X2000 Spitz Plus is the kind of gear that makes you wonder why more companies don’t build this. It’s a 4G LTE cellular gateway — not a router that happens to take a SIM card, but a device designed around cellular connectivity as its primary job. At 4.2 stars from 210 ratings, it’s not flawless, but it solves a very specific problem very well.

What You Actually Get

The box includes the Spitz Plus unit itself, two detachable external LTE antennas, a 12V/2A power adapter, an Ethernet cable, and a quick-start guide. The router measures roughly 5.5 x 4.5 x 1.5 inches — compact enough to tuck behind a TV or mount on a wall with the included brackets. On the back you’ll find two Gigabit LAN ports, one Gigabit WAN port, two SIM card slots (micro and nano), and a USB 2.0 port. Notably, there’s no built-in Wi-Fi — this is a wired gateway, so plan on pairing it with your own access point or router.

Real-World Performance

I tested the Spitz Plus with a T-Mobile SIM in a semi-rural area where my phone got two bars. With the external antennas attached and positioned near a window, the router pulled a consistent 85-110 Mbps down and 20-30 Mbps up. That’s not fiber territory, but it’s more than enough for Zoom calls, streaming, and light file transfers. The dual SIM failover works as advertised — when I pulled the active SIM, the router switched to the backup carrier in about 15 seconds with no manual intervention.

The device runs OpenWrt 22.03, which is both a blessing and a curse. Power users get granular control: band locking, carrier aggregation settings, modem status monitoring, and VPN server configs for WireGuard and OpenVPN. Less technical users will find the web interface intimidating. One reviewer put it well: “If you know what OpenWrt is, you’ll love this. If you don’t, budget an afternoon to learn.” The mobile app helps for basic setup, but it’s clearly a secondary thought.

What Buyers Consistently Praise

The dominant theme in positive reviews is reliability. A five-star reviewer wrote, “I’ve been through three cellular routers trying to get stable service for our farm office. This one has been up for 42 days straight without a single drop.” Another praised the failover: “The dual SIM feature saved our business when our primary carrier had an outage. We didn’t even notice until the warning email arrived.”

Build quality also gets consistent marks. The metal casing dissipates heat well, and the antenna connectors are sturdy — not the flimsy plastic fittings you see on cheaper units. The router handles power outages gracefully too, rebooting and reconnecting cellular automatically without requiring a manual reset.

Where It Falls Short

The most significant limitation is the lack of 5G. As carriers continue refarming LTE spectrum, this device will eventually become obsolete. For a $250+ investment, that’s worth considering. Several reviewers noted the fan — it’s quiet under normal use but becomes audible when pushing sustained data. One buyer described it as “a faint whir that’s fine in a closet but annoying on a desk.”

The Wi-Fi omission is also worth flagging. This is a gateway, not a full router. If you need wireless coverage, you’re buying an additional access point. GL.iNet also sells a Wi-Fi version (the Spitz X3000) for about $80 more, which may be the better value for most home users. The app setup experience drew some criticism too — it works, but the web interface is where the real configuration lives.

Who Should Buy This

The Spitz Plus is ideal for three specific buyers: RV and van dwellers who need a reliable internet drop-in that handles power fluctuations and multiple carriers; rural homeowners stuck with satellite or spotty LTE; and small businesses that need a dependable failover connection. If you’re a renter in a city with solid broadband options, this is overkill. And if you want an all-in-one router with Wi-Fi built in, look at the X3000 instead.

FAQ

Can I use this without a SIM card as a regular router? Yes. The WAN port accepts standard Ethernet from cable, fiber, or DSL. It works as a conventional router with the same OpenWrt features, just without the cellular benefits.

Does it support T-Mobile, Verizon, and AT&T? It’s unlocked and supports all major US carriers. For Verizon, check that the LTE bands cover your area — it supports B2, B4, B5, B12, B13, and B66, which is comprehensive but not exhaustive.

Can I use it as a VPN client and server simultaneously? Yes. OpenWrt allows multiple VPN interfaces. You can connect outbound to a commercial VPN while hosting a WireGuard server for remote access to your home network.

The Verdict

Buy it if you need dependable cellular connectivity with carrier redundancy, you’re comfortable with router configuration, and you want a device that will last years without software bloat. Skip it if you need 5G, want an out-of-the-box plug-and-play experience, or need integrated Wi-Fi.

The Spitz Plus is a specialized tool, not a mainstream consumer router. For its intended audience — remote workers, RV dwellers, rural offices — it’s one of the most reliable options on the market. It earns its 4.2 rating through solid hardware and excellent software flexibility, tempered by a learning curve and 4G-only status.
