Smartphones are PCs.
You can use your old Smartphone you are about to throw into a PC.
Steps:
First, however, you need to turn off cellular data. Otherwise, your phone will drain your battery trying to find a signal. On an iPhone, go to Settings>>Cellular. For an iPad, it’s Settings>>Cellular Data. Turn Cellular Data off.
In Android, swipe down from the top of the screen and look for the Mobile Data icon. You also might have a widget on your home screen.
Otherwise, go to Settings and under Wireless and Network, tap More Settings>>Mobile networks and uncheck Mobile data. The steps could vary by manufacturer, so check your manual if this doesn’t work for you.
On a Windows Phone, go to the App list and go to Settings>>Cellular. Turn Data connection to Off. Make sure “For limited Wi-Fi connectivity” is set to “Don’t use cellular data.”
Now it’s time to turn it into something else. The easiest option is a portable media player…
You can use that as a GPS,Alarm Clock,Gaming Unit,Kitchen Recipe Holder and WiFi Phone.
