Coinwink is a great new website, It could send you alerts on different coins, It send you an email though so you should install your email provider app in order to receive the notifications to phone that way.
If you want to make it like sending SMS then Coinwink is open source, you could modify the source code yourself and use Twilio API to send the text messages.
This one is cool.Thanks for sharing. I have created an akert for some currencies lets see how it works.
Hope they send real time price as sometimes even a small delay can cause you big loss.
