It’s hard to get too excited when talking about routers, but the Cudy LT500D is something special. That’s because it’s not just a router. It’s also a 4G LTE modem. That means, when you snap in a SIM card from your favorite cellular provider, it becomes an always-available Internet connection regardless of where you happen to be. Yes, you can get too far out in the wilderness and lose connectivity. But the router requires an electric outlet to work so in virtually all environments with AT&T or T-Mobile access, you’re covered. Whether it’s camping out or a mountain cabin or a beach house, the LT500D is a winner. It provides instant WiFi connectivity to the Internet for your entire family. You also can send and receive SMS messages using the web interface. And there’s an awesome bonus. If you currently have Comcast or Spectrum service which regularly goes out to lunch, the Cudy LT500D is a perfect complement. Why? Because it can be configured as an automatic failover during outages.
After updating the firmware, we tested the router with SIM cards from BoostMobile and T-Mobile. Setup took less than a minute. Simply activate your SIM card in a cell phone, and then pop the card into the LT500D. It automatically configures the router to support your carrier of choice. After a reboot, you simply access the LT500D dashboard by using a browser to connect to 192.168.10.1. You can also configure an OpenVPN client connection on the router and provide VPN access to anyone that makes a WiFi connection to the router.
Choosing a cellphone plan for your router is perhaps the trickiest deployment component. Most providers don’t like devices that let multiple people share a SIM card. The best deal we could find was this current BoostMobile 5GB data plan which costs just $5 a month for the first three months. After that, you can search for another deal, or you can be clever and buy several SIM cards from BoostMobile and register down the road with a different email address. You might also consider MintMobile which sells an introductory unlimited data, 3-month plan for $15 a month. With unlimited plans, some have suggested that you may need to make your router look more like a cellphone to avoid service interruption. We don’t traffic in details for flying under the radar, but Google is your friend.
What we will share is how to configure your router as an OpenVPN client which then gives all of your WiFI users access to all of the OpenVPN clients in your virtual private network. First, create and download an OpenVPN configuration file (cudy.ovpn) from your OpenVPN server. Then, on the Cudy router, choose the General Settings menu and click on the VPN icon. Activate the Enable and Site-to-Site tabs. For the Default Rule, choose Allow All Devices. For the VPN Subnet, choose Remote Subnet. Click Edit Item and add an Allow Listed Only Rule for 10.8.0.0/255.255.255.0. Click Save. For the OpenVPN Config File, click Browse and select the cudy.ovpn file downloaded from your OpenVPN server. It will automatically fill in your OpenVPN server’s FQDN. Now click Save & Apply to bring your OpenVPN client on line. You can test things by logging in via WiFi from a PC and using a browser to access one of the 10.8.0 addresses on your virtual private network.
In conclusion, this is one of the best routers we have ever tested or used. The Advanced Settings Dashboard is in a league of its own. At $129, the Cudy LT500D is a steal. Using our referral link helps pay the bills at Nerd Vittles. Enjoy!

I have been using this with a SIM card from Tello.com
Looks like a nice plan Victor. It seems the Mint Mobile is attractive too. Of course, what works is better than specifications on a web page.
