| "Easy to invite others. Just sends a simple SMS/text" and then "In countries like the US, SMS/Texting is very expensive...Whatsapp solved this problem" You need texting (a X dollar/month service) to use the service ... which solves the problem of... expensive texting? I always found that to be somewhat odd, using a service you're trying to replace/compete with as the sole authenticating factor. Edit: I realized after actually using the app, they do in fact offer an alternative authentication method (call). You have to try (and fail) at the texting method first. Also, in response to derefr (I deleted my ignorant parent comment), I block texting as even if you don't pay for a plan, you still get random spam texts that you must page for (even if you didn't ask for them) |
