Buying Guide: What to Look for in a 5G Router with SIM Card Slot
Network Compatibility and Speed
Not all 5G routers support the same frequency bands. Ensure the router you choose works with your carrier’s 5G network, whether it uses sub-6 GHz or mmWave. Models like the SquareWiz RM520N feature the Qualcomm SDX62 modem for speeds up to 3.4 Gbps, while the Hitron D60 is certified with T-Mobile, AT&T, and US Cellular. For 4G fallback, the Cudy LT500 offers reliable Cat 4 LTE.
Wi-Fi Performance
A fast 5G connection is wasted on outdated Wi-Fi. Look for Wi-Fi 6 (802.11ax) routers like the SquareWiz and Hitron, which deliver up to 2.4 Gbps on the 5 GHz band. Dual-band or tri-band designs ensure multiple devices can stream, game, and video conference without lag. The Cudy LT500 uses Wi-Fi 5, which is still capable for most households.
VPN and Security Features
If you need secure remote access or privacy, look for built-in VPN support. The SquareWiz RM520N includes WireGuard, OpenVPN, and Zerotier, while the Cudy LT500 offers WireGuard and OpenVPN. These features are essential for business users and travelers. For more on secure connections, see our top travel routers with VPN guide.
Portability and Antenna Design
For on-the-go use, compact routers with detachable antennas offer flexibility. The Portable 4G/5G WiFi Hotspot is pocket-sized with a built-in battery, ideal for camping and road trips. If you’re living the RV lifestyle, our best travel routers for RV living guide has more tailored recommendations. The SquareWiz and Hitron models feature external antenna ports for improved signal in weak coverage areas.
Final Thoughts
Choosing the right 5G router with a SIM card slot depends on your need for speed, carrier compatibility, and portability. For maximum performance and advanced VPN features, the SquareWiz RM520N AX3000 WiFi 6 Modem 5G Router is our top pick. If you prefer a carrier-certified device with dual failover capability, the Hitron D60 5G Cellular Router with Sim Card Slot offers excellent reliability. Both models deliver fast, secure internet wherever you go.
Frequently Asked Questions
Can I use a 5G router with any SIM card?
Most unlocked 5G routers accept standard nano SIM cards from any carrier, but you must ensure the router supports the carrier’s frequency bands.

What is the difference between 5G and 4G routers?
5G routers offer significantly faster download speeds, lower latency, and better capacity than 4G LTE routers. They are ideal for streaming 4K video, online gaming, and video conferencing.
