Fixed IP SIM Cards provide a convenient way to enable remote access to your M2M router. We offer 4G Fixed IP SIM Cards and 5G Fixed IP SIM Cards as well as roaming Fixed IP SIM Cards. We can provide SIM cards with a public IP address, which means you can communicate with your 4G router directly and use port forwarding to connect directly to your devices on the LAN. We also offer private fixed IP sim cards which provide a 4G connection with a private, fixed IP address, so in order to connect to your 4G router remotely you first of all need to create a VPN connection from your PC to our VPN server, at which point you can now communicate with your routers and connected devices.
Of course, a Fixed IP SIM with a private IP address and access to the routers via a secure VPN connection will be more secure, but in some cases less convenient than communicating directly to fixed public IP address. Using a Fixed IP SIM with a public IP address will mean that you need to ensure your router firewall will need to be correctly configured and also the connected devices will also need to have their security settings configured to prevent any unauthorised access.
