10 Best Wifi Router With Sim Slots 2026 in the United States

The NETGEAR Nighthawk 5G Mobile Hotspot M7 is a strong choice if you're looking for a portable router with SIM slot support that works well while traveling or on the go. It supports 5G and 4G LTE networks and is unlocked, meaning you can use it with major US carriers like AT&T, T-Mobile, and Verizon, plus it has an eSIM option for easy setup without a physical SIM. This device offers the latest WiFi 7 standard, which promises very fast wireless speeds — up to 3.6 Gbps — making it suitable for multiple devices at once (up to 32), which is great for families or small groups. It also supports dual-band WiFi for better connection stability.

The built-in battery lasts about 10 hours, which should cover a full day of use away from power outlets. On the downside, it only has one SIM slot (with eSIM support) and no built-in Ethernet port, so you'll need an additional adapter if you want wired connections. Security is well-covered with WPA3 encryption, firewall protection, and automatic updates to keep your network safe.

Although the device is a bit pricey and might feel complex if you're new to mobile hotspots, its ease of use through the NETGEAR app for managing data plans and usage helps a lot. For those who travel frequently or need reliable, fast internet for multiple devices away from home or office, the M7 delivers a solid mix of speed, flexibility, and security.

However, it doesn’t come with a built-in battery, so it needs to be connected to a power source, which might limit its use in some mobile scenarios. Also, it lacks included power supply and antennas, so you’ll need to purchase those separately. The bundled 3-year NetCloud Mobile Essentials plan adds cloud management features, which help in monitoring and managing the network remotely, a plus for professional use.

The built-in 6400mAh battery provides up to 8 hours of use without power, so it can keep your internet running during outages or on the go. On the security side, the router includes popular VPN options like OpenVPN and WireGuard to keep your network traffic private, plus options like DNS over TLS/HTTPS for extra protection. It also offers Ethernet ports and supports multi-WAN configurations, which means you can combine different internet sources for better stability. One thing to note is that the router uses a single standby dual-SIM setup, so only one SIM is active at a time, which might be a slight limitation if you want simultaneous connections.

The router runs on OpenWrt firmware, allowing advanced users to customize settings with many plugins, though beginners might find this a bit complex. Lastly, the physical eSIM support adds flexibility but requires purchasing the card separately. This router is well-suited for professionals or anyone needing dependable mobile internet with good speed, security, and backup power, while casual users might find some features more advanced than necessary.
