Following are the situations in which we have to depend on wireless connection:

1. During international tours or trips, while travelling in public transports like train and metro, mobile data is not sufficient and we have to face problems like roaming charges while travelling from one place to another. For this, we depend on alternatives or networks like wireless connection.

2. During international tours and trips, SIM card has to be ported from international number and for that a separate recharge plan has to be taken and KYC process has to be done. For this, if we talk about alternative options, then we can use wireless connection.

   Network Security:

Network security is a very big issue. Problems like data copy, data duplication, data misuse, ownership replacement, security breach can be faced. Therefore, while using wireless connection, activate security feature in the phone. Use wireless connection only from secure networks with password and do not use wireless connection service from unknown and unfamiliar network connections.

While using wireless connection, take special care to check in downloading manager, file manager and application manager that no other application, any other file or other software has been downloaded. This can be some kind of virus-containing data which can cause problems like hanging of your phone, operating system functionality failure, surveillance and remote operating.

We should pay attention to network security even when we are using wireless connection because the one through which we connect can cause problems like virus transmission, malware transfer to your phone, data leak and data misplacement.

Do not use open wireless connection in a crowded place.
While using facilities like online payment transfer and online banking, wireless connection should be used only from a safe and trouble free public place. Those who use facilities like network security, malware security and fire fall along with internet connection. 

For this also, tools or software like online keyboard random keyboard typing can be used so that the key stock of password or user ID is not known and neither this data is available to anyone else.

You can use these Wi-Fi software sources for Windows or PC. NetSpot, Acrylic, WiFi Analyzer, Wireshark, GlassWire etc. are great tools. These tools provide information about network security, signal strength, WiFi network status, network speed etc.

WiFi Map, Instabridge, Fing etc. are great tools for mobile phones and iOS devices. They provide important information about network speed, port scanner, diagnosing issues, network monitoring etc.
