How can a Conexa SIM card be accessed remotely?

Conexa SIM cards are characterised by their high redundancy, as they are equipped with two IP addresses. This dual IP addressing represents a significant advantage, enhancing the reliability and stability of the connection. In the event of a failure or disruption of the primary IP address, a seamless switch to the secondary IP address occurs, thereby ensuring the continuity of service. 

The remote access to a Conexa SIM card is facilitated through a VPN connection to the primary or secondary IP address of the SIM card, depending on which one is currently active. When remote access is conducted via the hostname, the currently active IP address is automatically addressed. 

Remote Access via hostname (using a VPN connection)

Ideally, remote access to a Conexa SIM card should occur through the hostname, ensuring that the currently active IP address is automatically utilised. The hostname is composed of the MSISDN of the SIM card and .LD.APNDNS.NET , for example: 883190603000000.LD.APNDNS.NET

Example:
Remote access to a Teltonika router with the Conexa SIM card, where remote access has been enabled via HTTPS port 4444:

1. Establish the VPN connection on your PC.
2. Open the web browser and enter the hostname: https://883190603000000.LD.APNDNS.NET:4444
3. The login page for the Teltonika router's WebUI will be displayed.

Determining active IP address (using a VPN connection)

Should an IP address be required for remote access instead of the hostname, the currently active IP address of the Conexa SIM card can be determined via the hostname using nslookup or ping as described below:

1. Establish the VPN connection.
2. Open the command prompt by typing "CMD" in the search box on your Windows PC.
3. In the command prompt, the active IP address of the Conexa SIM card can be resolved by entering "nslookup <hostname>". The active IP address will then be displayed under "Address", as illustrated in the example below:
   

   C:\users\xxx>nslookup 883190603000000.LD.APNDNS.NET
   
   Name: 883190603000000.LD.APNDNS.NET
   Address: 100.xxx.xxx.xxx
   
   C:\users\

4. Alternatively, instead of nslookup, you may send a ping to the hostname in the command prompt. The current IP address of the SIM card will then be displayed in square brackets, as shown in the following example:

   C:\Users\xxx>ping 883190603000000.LD.APNDNS.NET
   
   Pinging 883190603000000.LD.APNDNS.NET [100.xxx.xxx.xxx] with 32 bytes of data:

Remote Access via web.direct Link (using DevicePro)

As an alternative to the VPN connection, remote access to an HTTP or HTTPS web server can be realised through the SIMPro feature DevicePro using web.direct, for example, to access the WebUI of the mobile router. This method provides an efficient and user-friendly solution for accessing web content without the need for a VPN connection.
