A proxy is a system or router that provides a gateway between users and the internet.
What is Proxy in APN Settings?
The Proxy field is an optional field allowing you to specify the address of an HTTP proxy to use for all web traffic over this connection. Carriers sometimes use HTTP proxies to modify websites for your device or to improve the speed of common access web pages and resources by caching them.
It’s relatively rare for a carrier to require that you use an HTTP proxy for your connection. In addition to this, many carriers use HTTP proxies that don’t even require this field to be set, known as transparent proxies.
The first field specifies the address of the proxy server. This may be given as an IP address (for example, numbers connected with dots or colons such as 22.214.171.124), or as a hostname.
As always, consult your carrier’s recommended APN settings to see whether they recommend that you add the address of their proxy server into this field. Many carriers won’t use or require a proxy, meaning this setting should remain empty.
Do I need to set Proxy in My APN Settings?
Simply no. As it is an option filed, you don’t need to set a proxy server but if your carrier network recommends you to add it, then you should do so.
