This trick discusses "how to quickly find a free proxy server and port", bookmark or bookmark the following search engine websites: 

1. Tejji.com 

2. Ping.eu - Furthermore, the first step in finding a proxy server is to search for advertising information from cellular operators on television, newspapers, or the internet, because through these advertisements you can monitor promotions offered by operators, which you can make bugs on.

- The second step, the operator site or query that is suspected of containing the proxy server you recorded. For example: server4.operamini.com. Therefore, many proxies from Opera Mini can be used as a medium for free internet. 

- Third step, change the URL or domain that you noted earlier to the Numeric IP with Tejji.com. As an example: server4.operamini.com => 141.0.11.253. 

- The fourth step, note the Numeric IP. Then enter Ping.eu. On the Ping.eu web: 

1. Select "whois", enter the Numeric IP into the column and click "go". There are various kinds of information in it (you just ignore it) 
2. Then click "proxy checker", fill in the port column with the following numbers: 8000, 8080, 80, 3128, 3124, 9201, 9002 (all port numbers are commonly used for the internet), even if there are other ports, the function is clear different. 
3. Later you will get notifications, including: => connection time out => connection refused => 141.0.11.253:80 is not a proxy server => 141.0.11.253:80 is a proxy server Note: find the proxy server to find some port numbers above.
4. If you have obtained a proxy server, click "port check". Usually it is detected as a proxy checker, which is the port "open". The notification is like this: 141.0.11.253:80 port is open 
5. Well, IP: 141.0.11.253 and port: 80 this is what you make a new configuration setting or file prov. For APN, you can fill it according to the operator you are using. For example Telkomsel, IndosatM2, 3Gprs, and others. 
6. Test first on your mobile browser. Try opening 0.facebook.com or whatever. If you can connect, it means you can use an internet access point. 

If you are lucky, you can get free internet on your mobile browser. If it's not free, we can manipulate it with Opera Mini. 

You already know the three free internet secrets ??? That part you can manipulate. Or if you have Opera Mini settings that might still be able to connect, for example settings in the Opera Mini Handler Menu, which was able to connect due to the proxy and the port being blocked by the operator, you can change the proxy and port in the mobile access point settings, with what you get just now. And connect through the new access point that you created above. 

Happy Free Internet !!! Good luck.
