GL.iNet GL-X750V2 Spitz 4G LTE AC750 VPN Router

The GL.iNet GL-X750V2 (Spitz) is a compact, OpenWrt-powered 4G LTE AC750 VPN router certified for AT&T and compatible with T‑Mobile, built for failover internet, IoT gateway use, and flexible customization.

Designed as an upgraded iteration of the original Spitz (GL-X750), the GL-X750V2 brings improved antenna design and a redesigned PCB to boost cellular reception in fringe and rural areas. It ships with the Quectel EC25-AFFA CAT4 module certified for AT&T IoT plans (North America only), dual-band Wi‑Fi (300 Mbps on 2.4 GHz and 433 Mbps on 5 GHz), and OpenWrt preinstalled so you can extend features, run VPNs, or add IoT services. The device omits BLE and is intended for use in approved countries — cellular functionality is restricted in several regions due to modem limitations.

How reliable is the GL-X750V2 for mobile or remote internet?

The GL-X750V2 is intended as a robust emergency backup or primary link where wired internet is unavailable. With the EC25-AFFA module and optimized antennas, you’ll generally get stable 4G connections suitable for browsing, cloud sync, and light streaming.

• AT&T-certified EC25-AFFA CAT4 module for approved IoT plans.
• Dual-band Wi‑Fi translates 4G to 300/433 Mbps wireless access.
• Average real-world 4G speeds typically fall in the 15–20 Mbps range (location-dependent).
• Works with T‑Mobile and AT&T networks in supported areas.

What security and VPN options are available out of the box?

The router arrives with OpenVPN and WireGuard pre-installed, and supports Cloudflare DNS for added privacy and DNS protection. Because it runs OpenWrt, you can also install additional security packages from the open-source repository.

How easy is it to set up and manage for IoT or network projects?

Setup is straightforward: insert a compatible micro SIM, connect power and an Ethernet device if desired, and use the OpenWrt web interface for configuration. The open-source platform makes it ideal for developers and network integrators who want programmable network behavior or to host lightweight services on the edge.

• Pre-installed OpenWrt/LEDE with web UI for configuration.
• Unlocked firmware for custom scripts and packages.
• Two Ethernet ports for WAN/LAN separation and failover setups.
• Community and documentation support for advanced configurations.

Who is this for? The GL-X750V2 (Spitz) is aimed at travelers, RV owners, boat operators, remote workers, and IoT integrators who need a portable, secure cellular router that’s both hackable and certified for AT&T IoT programs in North America. It’s a good fit where dependable 4G failover, VPN privacy, and firmware-level customization are priorities. Avoid purchasing if you require Bluetooth Low Energy or plan to use cellular services in countries where the modem is restricted.
