All my phone contacts were added, and for each of these, you can invite to use the app with an automatically generated email. After this, I was prompted to enter my name and choose a user picture. Happily, I just had to tap on the link in the SMS message to enter it into the app. After you enter my number, WhatsApp sent my phone a text message. I installed and tested the app on a Samsung ATIV Odyssey. To get started with WhatsApp, you'll need to enter your phone number, so if you have a device without cell service, you won't be able to use the app, even though it mostly uses Wi-Fi and cellular data to function. So, apparently, after a year of using the app, it's pay up or go home. I didn't see any indication of this subscription fee on the Windows Phone app store, but when I contacted WhatsApp to clear this up, they told me that the policy of one year free and 99 cents a year after that holds true for all platforms. WhatsApp is free to install but there's a 99 cent a year subscription after the first year. Read our editorial mission (Opens in a new window) & see how we test (Opens in a new window). Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. An advantage iMessage boasts, however, is that it offers a desktop client-Mac-only, of course-that lets you text iPhone users from your computer. That's a big advantage over the excellent yet insular iMessage iPhone app, though it's not unique among today's messaging apps.


One of the few benefits of WhatsApp is that you can use it to converse with your Android, Blackberry, and iPhone-using friends as well as with other Windows Phone users. But is all this popularity warranted? I have to admit that I'm at a loss to explain it. In fact, the WhatsApp's CEO claimed that it had more users than Twitter-over a quarter billion. So there's a good chance that your iPhone-toting pals will be reachable-even more so now that it's free to install. But among messaging apps intended to save users SMS texting costs, it certainly boasts a huge user base: In fact, WhatsApp peaked at one point as the 6th most popular paid app on the iTunes store, and Onavo (Opens in a new window)ranks it as the eighth most popular social app.

I was shocked to read a tech news article recently calling WhatsApp the "granddaddy" of messaging: I think ICQ would beg to differ.
