GPS tracking is available for your gadgets like your mobile phone or laptop. Some services are aimed at recovery if it’s lost or stolen. The first step is to register your GPS cell phone or laptop, but check out the fine print. It might not work unless the application is on, for example, making it pretty useless to find a lost phone with the power off or a stolen one if the thief knows to turn off the tracking app. On the other hand, if you want to know whether you left it in the office, the restaurant or the car, it might be just what you need.
To send a text message to a friend using your regular email account, you address it with the 10 digit phone number @ the email Web site URL of your friend's cell phone carrier. Note that's not the same as their main URL, it's a special one for text messaging. For example, AT&T is firstname.lastname@example.org, Verizon is email@example.com and T-Mobile is firstname.lastname@example.org.
