Solwise has partnered up with Europe's leading M2M & IoT Managed Services Provider to supply fixed IP SIM cards with public IP address assignments.

The UK mobile networks provide dynamic, private IP address assignments to 3G/4G devices which in most cases are perfectly adequate for home and general business use. Your Mobile Broadband internet connection is routed through a NAT firewall in your provider’s data centre, which adds security but also restricts the ability to connect to your Mobile Broadband device from the Internet.

Your provider will not be able to cater for any port forwarding requirements you may have, so an end-to-end connection to your device will not be possible even if your device is a 3G/4G router. This limitation can also prevent site-to-site cellular connections from being established for VPN applications and can be vital in M2M (machine-to-machine) or IoT (internet-of-things) services. It's also worth noting that even services like No-IP or DynDNS will also not work on the virtual addresses from your provider. So, for example, services like remote access to IP cameras will also not work. For these services you need a fixed/public IP address.
