If you prefer doing stuff on your own, you can purchase your own Wi-Fi router from your local computer store for under $100 and add it to your home network by following the included instructions inside its box.
Once its Wi-Fi is switched on, your old Android phone should automatically connect to your Wi-Fi network. If your network is password-protected, a dialog box will appear on your phone’s screen, asking you to type in a password. Just enter the password of your Wi-Fi network and your device should be able to connect to the Wi-Fi.
Google Play Store is the application market where you can download software exclusively for Android devices.
VoIP, or Voice-over Internet Protocol applications, are softwares designed for Android that let you make phone calls and even send out text messages for free using Internet connectivity instead of the traditional telephone or mobile phone lines. This makes the calls, if not at all free, a lot cheaper than your normal phone calls using your landline or mobile network. There are several VoIP apps that you can find on Google Play Store. Some of the most popular choices are Viber by Viber Media and Zoiper IAX SIP VOIP Softphone by Securax LTD.
Tap the green “Accept” button on the Permissions page that appears, and the VoIP app you selected will be automatically downloaded and installed on your Android.
To place a call, simply dial the telephone or mobile number you want to reach using the app’s keypad and press the call key (phone icon) you’ll see on the same section to begin the call. You’ll hear the usual phone ring from the other end of the line once the application successfully connects to the number you dialed.
