As a result, this gives you the ultimate connectivity for your business, the fastest internet available on 4G and the ability to connect anytime, anywhere, choose an M2M Data Connect fixed IP SIM card.

Why Do I Need A Fixed IP SIM Card with Public IP Address?

If you want to remotely access your 4G router over the mobile broadband Internet then a Fixed IP SIM card  is needed.  A fixed IP SIM card with Public IP address is the most convenient way to ensure reliable connectivity because you always know what your 4G router IP address is.  As a result, when your router reboots it will always have the same IP address and you manage your SIMs using our M2M SIM management.

Whats difference between  standard data SIM and a Fixed IP SIM Card with Public IP Address?

If you use a standard Data SIM card to connect to the internet over the 4G network and visit then the IP address it shows is the public IP address for the mobile network.   The mobile network IP address is shared over many other different user devices.  As a result you will be unable connect to your router and connected devices because your normal data SIM has a private IP address.

To get a standard Data SIM card obtained directly from the mobile network then you would probably need to have a VPN server at your head office and configure each of your 4G routers as VPN clients to connect to your head office server. As a result, the IP address allocated to your SIM connection will be a private IP on the mobile network.

This means that you can’t use Dynamic DNS / DDNS because the IP address that the router reports to your DYNDNS service will be the private one which is behind the actual public IP address on the mobile providers network.

To use Dynamic DNS / DDNS you will require a Fixed IP SIM Card with Public IP Address.  This allows you to connect to a router and connected IoT devices from any computer connected to the internet.  After inserting the SIM, you have to configure the M2M APN with inbound port filtering.  As a result, you get a fixed public IP connection to allow remote access to your devices.

Fixed IP SIM Cards with Public IP address

M2M Data Connect offer mobile data SIM cards with a public IP address.  This means that once you insert your SIM card into your 4G router and have correctly configured your SIM Card APN settings the router will connect to the 4G network.   This gives you a publicly available IP address that never changes.

Your router will then connect to the  Internet connection with a fixed, public IP address you can communicate to the router directly from anywhere on the Internet and then use port forwarding to connect to your devices on the LAN.  When using a fixed IP SIM card with a public IP address ensure that your 4G router firewall settings are correctly configured because your router will be exposed to the internet.  Many routers will have advanced features and restrict inbound connections to a single IP address or IP address range.
