What is an APN?

Access Point Name or APN is the name of an access point for GPRS/3G/HSDPA/HSUPA.
An access point is:

• An Internet network to which a mobile can be connected
• A set of settings which are used for that connection
• A particular option in a set of settings in a mobile phone

What is an IP address?

Every machine on the Internet has a unique identifying number, called an IP Address. A typical IP address looks like this:
234.345.2.137
To make it easier to remember, IP addresses are normally expressed in decimal format as a ‘dotted decimal number’ as illustrated above.
An easy way to understand what an IP address is to compare it to a postal address. The IP address contains the country, county, town, street and building number. With this information, data can be routed to all machines. If a machine has no IP address, no data will be able to reach it.

What is a Private IP address?

An IP address is considered private if the IP number falls within one of the IP address ranges reserved for private uses by Internet standards groups. These private IP address ranges exist through the following ranges:
10.0.0.0 through 10.255.255.255
169.254.0.0 through 169.254.255.255 (APIPA only)
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255
Private IP addresses are typically used on local networks including home, school and business LANs including airports and hotels. Devices with private IP addresses cannot connect directly to the Internet. Likewise, computers outside the local network cannot connect directly to a device with a private IP. Instead, access to such devices must be brokered by a router or similar device that supports Network Address Translation (NAT). NAT hides the private IP numbers but can selectively transfer messages to these devices, affording a layer of security to the local network.

What is a Fixed IP address?

A fixed IP address is sometimes known as a static IP address. It is an address that is assigned to a computer by an Internet service provider (ISP) to be its permanent address on the Internet.
Computers use IP addresses to locate and talk to each other on the Internet, much the same way people use phone numbers to locate and talk to one another on the telephone. The machine will retain that IP address no matter how many times it connects/disconnects from a network.

What is a dynamic IP address?

This in simple terms is the opposite of a fixed IP address. When a machine connects to the network, an IP address is assigned to it. However, when the machine disconnects, it loses the IP address
The next time the machine connects, it will pick up a new IP address.
What is the advantage of a Private IP address over a Public IP address?
The IP address for the device is ‘hidden’. As a result, the device cannot be accessed from any machine anywhere unless there is a secure VPN tunnel set up between the device and the machine. This creates an additional level of security for those who deem their data to be highly sensitive.

What is the advantage of a Private APN?

The benefit is that the traffic is secure and never goes on to a public network, staying completely on GPRS/3G/4G. This lessens complexity in the communications path and is one less point of failure in the system.
As it is secure, this means that you will not be open to attack external parties, such as spammers or virus-based activities.

What is a VPN tunnel?

A VPN is a private network that uses a public network (usually the Internet) to connect to devices with Private IP addresses from a machine on your LAN or from home. Instead of using a dedicated, real-world connection such as leased line, a VPN uses ‘virtual’ connections routed through the Internet from the company’s private network to the remote device.
The VPN tunnel would be used for those who have a private IP address on their SIMs.

What is a site-to-site VPN tunnel?

A site-to-site VPN tunnel is where two firewalls are used to create a VPN tunnel. We configure a firewall on our side and then send the config parameters to the customer. The customer would then need to enter the config parameters onto their firewall/router. This would then enable any machine(s) on a company’s LAN to connect to its devices with our m2m SIMs and vice versa. This is an always-on VPN connection. To create a site-to-site tunnel, customers would need to have a hardware firewall/router capable of setting up an IPSEC VPN tunnel.

How to access a router and camera remotely

For the VPN access we recommend OpenVPN and the instructions to install are below.

OpenVPN Software:

Download the OpenVPN software below using the link and then import the attached certificate into the OpenVPN.

Right click on OpenVPN icon

Select Import then import file. Select the certificate which you downloaded.

Once downloaded go back to OpenVPN in control panel and select the VPN name and connect. 

You can then type in the router IP in a web browser to gain access to your routers, Eg -  IP 10.32.2.61

SIM Card Doesn't Connect GPRS

What to do next
In order to connect your SIM to the GPRS network and let it pick up the fixed Private IP address, you will need to enter the Go2SIm Private APN login credentials. These can be found in the knowledge section.
In the unlikely event that the SIM card does not connect to the GPRS network, in the first instance, please do the following:
Place the Go2Sim SIM card into unlocked handset which has the ability to connect to the internet.
Check to see if it connects to the network. If not, please contact the Go2Sim Support team via a ticket on our support portal.
If it connects to the network, then try to connect to the internet. If you are able to connect to the internet then the Go2SIm SIM and the profile it is using is working OK.
